Android项目实战（二十七）：数据交互（信息编辑）填写总结-阿里云开发者社区

前言：

　　项目中必定用到的数据填写需求。比如修改用户名的文字编辑对话框，修改生日的日期选择对话框等等。现总结一下，方便以后使用。

注：

　　先写实现过程，想要学习的同学可以看看，不需要的同学可以直接拉到最下面复制代码使用。

------------------------------------------------------------------------------------------------------------------------------------

一、文字编辑对话框

看下效果图（仿今日头条）：

需求包括：

一个标题TextView

一个圆角白色背景EditText

一个可输入个数提示的TextView

两个按钮，‘确定’、‘取消’

对话框展现形式。

代码实现：

（1）编写布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/grey_5"
    android:id="@+id/popup_edit_info_ly"
    >
    <!--标题-->
    <TextView
        android:id="@+id/popup_edit_info_txt_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="title"
        android:gravity="center_horizontal"
        android:padding="@dimen/dp_6"
        android:textColor="@color/black"
        />

    <!--编辑框-->
    <EditText
        android:id="@+id/popup_edit_info_edit_content"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="@dimen/dp_6"
        android:layout_marginRight="@dimen/dp_6"
        android:background="@drawable/bg_popup_edit"
        android:padding="@dimen/dp_6"
        >
    </EditText>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="@dimen/dp_6"
        >
        <!--提示文字-->
        <TextView
            android:id="@+id/popup_edit_info_txt_tip"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="@dimen/txt_10"
            android:text="剩余可输入个数:"
            android:layout_centerVertical="true"
            android:layout_marginLeft="@dimen/dp_6"
            />

        <!--确定按钮，这里用TextView ，当然也可以用Button ImageButton-->
        <TextView
            android:id="@+id/popup_edit_info_btn_confirm"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/confirm"
            android:background="@drawable/bg_btn_blue"
            android:padding="@dimen/dp_4"
            android:textColor="@color/white"
            android:layout_alignParentRight="true"
            />

        <!--取消按钮-->
        <TextView
            android:id="@+id/popup_edit_info_btn_cancel"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/cancel"
            android:background="@drawable/bg_btn_grey"
            android:padding="@dimen/dp_4"
            android:textColor="@color/white"
            android:layout_toLeftOf="@id/popup_edit_info_btn_confirm"
            android:layout_marginRight="@dimen/dp_10"
            />
    </RelativeLayout>

</LinearLayout>

dialog_edit_txt

里面编辑框EditView涉及到了圆角白色背景需要写一个drawable文件

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <!--popupwindow 编辑框的背景颜色 用于popup_edit_info.xml布局文件-->
    <solid android:color="@color/white" ></solid>
    <corners android:radius="@dimen/dp_6"></corners>
    <stroke android:width="0.5dp" android:color="@color/grey_1"></stroke>
</shape>

bg_popup_edit

(2)、在activity或者fragment中使用

　　①、这里我把对话框写在一个方法里，方便使用

title 文本对话框的标题
isSingleLine EditText是否限制一行显示
maxSize EditText中文字的最大长度
textview 修改的TextView控件，首先要讲该控件的文本显示在EditText中，点击确定后需要将编辑文本显示在改控件中

private void showEditDialog(String title , boolean isSingleLine , final int maxSize, final TextView textview)

　　②、根据布局文件生成view 并初始化控件

　　　　 View view = LayoutInflater.from(this).inflate(R.layout.dialog_edit_txt, null);
        TextView popup_edit_info_txt_title;//标题
        final TextView popup_edit_info_txt_tip;       //编辑框剩余个数提示
        TextView popup_edit_info_btn_cancel;    //取消按钮
        TextView popup_edit_info_btn_confirm;    //确定按钮
        final EditText popup_edit_info_edit_content;   //编辑框
        popup_edit_info_txt_title = (TextView) view.findViewById(R.id.popup_edit_info_txt_title);
        popup_edit_info_txt_tip = (TextView) view.findViewById(R.id.popup_edit_info_txt_tip);
        popup_edit_info_btn_cancel = (TextView) view.findViewById(R.id.popup_edit_info_btn_cancel);
        popup_edit_info_btn_confirm = (TextView) view.findViewById(R.id.popup_edit_info_btn_confirm);
        popup_edit_info_edit_content = (EditText) view.findViewById(R.id.popup_edit_info_edit_content);

　　③、进行控件的属性设置

 　　　　popup_edit_info_edit_content.setText(textview.getText().toString());            // 将参数textview的文本数据显示在EditText中
        popup_edit_info_edit_content.setSingleLine(isSingleLine);                       // 设置EditView是否单行，像用户名这种信息需要单行，像评价简介这种的不需要单行
        popup_edit_info_edit_content.setFilters(new InputFilter[]{new InputFilter.LengthFilter(maxSize)}); // 设置EditText的最大长度，当输入超过这个值的时候不在允许输入
        popup_edit_info_txt_tip.setText("剩余可输入个数:"+(maxSize-textview.getText().toString().length()));        // 设置 剩余文字个数提示

　　     popup_edit_info_edit_content.setSelection(content.getText().length()); // 光标默认显示在最后

        final AlertDialog dialog = new AlertDialog.Builder(this)                        //创建对话框
                .setView(view)
                .create();
        popup_edit_info_txt_title.setText(title);                                       // 设置标题

　　　 　dialog.setCanceledOnTouchOutside(false);                                         // 设置点击屏幕Dialog不消失

　　④、进行EditText的设置，监听文字数据字数变化，改变提示文本的内容

　　　　　　popup_edit_info_edit_content.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
            }
            @Override
            public void afterTextChanged(Editable s) {
                int length = s.length();
                popup_edit_info_txt_tip.setText("剩余可输入个数:"+(maxSize-length));
            }
        });

　　⑤、设置‘确定’、‘取消’点击事件

popup_edit_info_btn_cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        popup_edit_info_btn_confirm.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                textview.setText(popup_edit_info_edit_content.getText().toString());
                dialog.dismiss();
            }
        });

　　⑥、显示对话框

dialog.show();

------------------------------------------------------------------------------------------------------------------------------------

二、单个条件选择的自定义PopupWindow

效果图：

需求包括：

1、顶部两个按钮：“取消”、“确定”按钮

2、标题

3、滚动的wheelview选择器

代码实现：

1、选择一个WheelView控件，这个github上很多，我这里选用的是

　　https://github.com/xiangyunwan/WheelView-master/

　　在app目录下的 build.gradle文件中添加

compile 'com.wx.wheelview:wheelview:1.3.3'

2、构建PopupWindow布局文件

　　这个比较简单，按效果图来两个按钮，一个标题文本，一个WheelView

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/popup_one_item_ly"
    android:background="@color/white"
    >

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/grey_6"
        >
        <Button
            android:id="@+id/popup_one_item_btn_cancel"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="#0000"
            android:text="取消"

            android:textColor="@color/line_blue_main"
            />

        <Button
            android:id="@+id/popup_one_item_btn_submit"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="确定"
            android:layout_alignParentRight="true"
            android:background="#0000"
            android:textColor="@color/line_blue_main"
            ></Button>

        <TextView
            android:id="@+id/popup_one_item_txt_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/black"
            android:layout_centerInParent="true"
            />
    </RelativeLayout>

    <com.wx.wheelview.widget.WheelView
        android:id="@+id/popup_one_item_wheel"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginLeft="@dimen/dp_20"
        android:layout_marginRight="@dimen/dp_20"
        >

    </com.wx.wheelview.widget.WheelView>

</LinearLayout>

popup_one_item

对应的几个资源：

<color name="grey_6">#faf9f9</color>
<color name="blue_main">#4ab8e9</color>

3、写一个封装的继承PopupWindow的类，以后类似的直接拿来用即可，这里命名OneItemPopupWindow

　 ①、参数分析

　　需要上下文 Context 用于构建View

　　需要点击事件，接口回调的方式 View.OnClickListener

　　需要标题文本，String

　　需要WheelView显示的数据源，ArrayList<String>

　　所以构造方法：

public OneItemPopupWindow(Context context, View.OnClickListener itemsOnClick, String t, ArrayList<String> datas) {
        super(context);
}

　　②、定义需要的数据

    private View mMenuView; //popupwindow布局生成的View
    private TextView title; //标题
    private Button cancel;  //取消按钮
    private Button submit;  //确定按钮
    private WheelView wheel;  //wheelview控件
    private int currentPosition;  // 当然的wheelview选择的item的位置
    ArrayList<String> datas = new ArrayList<>();    // wheelview的数据源

　　③、生成PopupWindow的View 并获取相应控件初始化，从这里开始都写在构造方法里

　　　　　LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mMenuView = inflater.inflate(R.layout.popup_one_item, null);
        cancel = (Button) mMenuView.findViewById(R.id.popup_one_item_btn_cancel);
        submit = (Button) mMenuView.findViewById(R.id.popup_one_item_btn_submit);
        wheel = (WheelView) mMenuView.findViewById(R.id.popup_one_item_wheel);
        title = (TextView) mMenuView.findViewById(R.id.popup_one_item_txt_title);
        this.datas = datas; //根据参数初始化数据源
        title.setText(t);   //设置标题

　　④、设置wheelview控件的相应属性方法

　　　　 wheel.setWheelAdapter(new ArrayWheelAdapter(context)); // 文本数据源
        wheel.setSkin(WheelView.Skin.Holo); // common皮肤
        wheel.setWheelData(datas);  // 数据集合
        wheel.setOnWheelItemSelectedListener(new WheelView.OnWheelItemSelectedListener() {
            @Override
            public void onItemSelected(int position, Object o) {
                currentPosition = wheel.getCurrentPosition();
            }
        });
        cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        submit.setOnClickListener(itemsOnClick);

　　⑤、设置PopupWindow的自身属性方法

　　　　 this.setContentView(mMenuView);
        this.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
        this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
        ColorDrawable dw = new ColorDrawable(0x000000);
        this.setBackgroundDrawable(dw);
        this.setFocusable(true);
        //点击popupWindow之外的部分  关闭popupWindow
        mMenuView.setOnTouchListener(new View.OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                int height = mMenuView.findViewById(R.id.popup_one_item_ly).getTop();
                int y = (int) event.getY();
                if (event.getAction() == MotionEvent.ACTION_UP){
                    if(y<height){
                        dismiss();
                    }
                }
                return true;
            }
        });

到这里构造方法完成了，然后我们需要写一个方法，让new OneItemPopupWindow(...)的Activity能获取到数据源选中位置的数据

　　 public int getCurrentPosition() { // 获取到wheelview当前选中的位置
        return currentPosition;
    }

    public ArrayList<String> getDatas() { //获取wheelview的数据源
        return datas;
    }

自定义 OneItemPopupWindow 的全部代码

import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

/**
 * Created by 徐启鑫 on 2016/11/15.
 * 一个选项的popupwindow
 */
public class OneItemPopupWindow extends PopupWindow{

    private View mMenuView; //popupwindow布局生成的View
    private TextView title; //标题
    private Button cancel;  //取消按钮
    private Button submit;  //确定按钮
    private WheelView wheel;  //wheelview控件
    private int currentPosition;  // 当然的wheelview选择的item的位置
    ArrayList<String> datas = new ArrayList<>();    // wheelview的数据源

    public int getCurrentPosition() {
        return currentPosition;
    }

    public ArrayList<String> getDatas() {
        return datas;
    }

    public OneItemPopupWindow(Context context, View.OnClickListener itemsOnClick, String t, ArrayList<String> datas) {
        super(context);

        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mMenuView = inflater.inflate(R.layout.popup_one_item, null);
        cancel = (Button) mMenuView.findViewById(R.id.popup_one_item_btn_cancel);
        submit = (Button) mMenuView.findViewById(R.id.popup_one_item_btn_submit);
        wheel = (WheelView) mMenuView.findViewById(R.id.popup_one_item_wheel);
        title = (TextView) mMenuView.findViewById(R.id.popup_one_item_txt_title);

        this.datas = datas; //根据参数初始化数据源
        title.setText(t);   //设置标题

        wheel.setWheelAdapter(new ArrayWheelAdapter(context)); // 文本数据源
        wheel.setSkin(WheelView.Skin.Holo); // common皮肤

        wheel.setWheelData(datas);  // 数据集合
        wheel.setOnWheelItemSelectedListener(new WheelView.OnWheelItemSelectedListener() {
            @Override
            public void onItemSelected(int position, Object o) {
                currentPosition = wheel.getCurrentPosition();
            }
        });
        cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        submit.setOnClickListener(itemsOnClick);

        this.setContentView(mMenuView);
        this.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
        this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
        ColorDrawable dw = new ColorDrawable(0x000000);
        this.setBackgroundDrawable(dw);
        this.setFocusable(true);
        //点击popupWindow之外的部分  关闭popupWindow
        mMenuView.setOnTouchListener(new View.OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                int height = mMenuView.findViewById(R.id.popup_one_item_ly).getTop();
                int y = (int) event.getY();
                if (event.getAction() == MotionEvent.ACTION_UP){
                    if(y<height){
                        dismiss();
                    }
                }
                return true;
            }
        });

    }
}

OneItemPopupWindow

至此封装好了一个有一个筛选条件的自定义PopupWindow

4、OneItemPopupWindow 的使用

　　　　　　　　　 ArrayList<String> condition = new ArrayList<>();  //构建数据源
                condition.add("北京");
                condition.add("上海");
                condition.add("浙江");
                condition.add("江苏");
                condition.add("山东");
                condition.add("山西");
                condition.add("广东");
                condition.add("福建");
                popup = new OneItemPopupWindow(this, selectItemsOnClick,"选择城市",condition);  //创建自定义的popupwindow对象
                // 设置popupWindow显示的位置
                // 此时设在界面底部并且水平居中
                popup.showAtLocation(find_expert_ly,
                        Gravity.BOTTOM| Gravity.CENTER_HORIZONTAL, 0, 0);
                // 当popupWindow 出现的时候 屏幕的透明度  ，设为0.5 即半透明 灰色效果
                backgroundAlpha(0.5f);
                // 设置popupWindow取消的点击事件，即popupWindow消失后，屏幕的透明度，全透明，就回复原状态
                popup.setOnDismissListener(new PopupWindow.OnDismissListener() {
                    @Override
                    public void onDismiss() {
                        backgroundAlpha(1f);
                    }
                });

5、监听事件的接口回调，也是写在创建 OneItemPopupWindow 对象的Activity中

private View.OnClickListener selectItemsOnClick = new View.OnClickListener() {
        public void onClick(View v) {
            switch (v.getId()) {
                //根据popupWindow 布局文件中的id 来执行相应的点击事件
                case R.id.popup_one_item_btn_submit:
                    String s = popup.getDatas().get(popup.getCurrentPosition());
                    find_expert_btn_location.setText(s);
                    break;
                // ....
            }
            //每次点击popupWindow中的任意按钮，记得关闭此popupWindow，
            popup.dismiss();
        }
    };

6、界面半透明效果方法

　　/**
     * 设置添加屏幕的背景透明度
     * @param bgAlpha
     */
    public void backgroundAlpha(float bgAlpha)
    {
        WindowManager.LayoutParams lp = getWindow().getAttributes();
        lp.alpha = bgAlpha; //0.0-1.0
        getWindow().setAttributes(lp);
    }

效果图：

------------------------------------------------------------------------------------------------------------------------------------

三、日期选择的自定义DatePopupWindow

需求同上，一个标题，一个确定按钮，一个时间按钮

　　　　三个水平排列的wheelview选择空间

效果图:

代码实现：

1、和 “单个条件选择的自定义PopupWindow” 实现类似，只是多了两个wheelview ，代码直接贴在最下面了

---------------------------------------------------------------------------------------------------------------------

完整代码：

一、文字编辑对话框

        cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }

        submit.setOnClickListener(itemsOnClick);



        this.setContentView(mMenuView);

                int y = (int) event.getY();
                if (event.getAction() == MotionEvent.ACTION_UP){
                    if(y<height){
                        dismiss();

DatePopupWindow

3、使用代码：

private void showDatePopupWindow() {

        popup = new DatePopupWindow(this, selectItemsOnClick,"选择日期",2015);  //创建自定义的popupwindow对象
        // 设置popupWindow显示的位置
        // 此时设在界面底部并且水平居中
        popup.showAtLocation(feedback_list_ly,
                Gravity.BOTTOM| Gravity.CENTER_HORIZONTAL, 0, 0);
        // 当popupWindow 出现的时候 屏幕的透明度  ，设为0.5 即半透明 灰色效果
        backgroundAlpha(0.5f);
        // 设置popupWindow取消的点击事件，即popupWindow消失后，屏幕的透明度，全透明，就回复原状态
        popup.setOnDismissListener(new PopupWindow.OnDismissListener() {
            @Override
            public void onDismiss() {
                backgroundAlpha(1f);
            }
        });
    }

    /**
     * 设置添加屏幕的背景透明度
     * @param bgAlpha
     */
    public void backgroundAlpha(float bgAlpha)
    {
        WindowManager.LayoutParams lp = getWindow().getAttributes();
        lp.alpha = bgAlpha; //0.0-1.0
        getWindow().setAttributes(lp);
    }
    private View.OnClickListener selectItemsOnClick = new View.OnClickListener() {
        public void onClick(View v) {
            switch (v.getId()) {
                //根据popupWindow 布局文件中的id 来执行相应的点击事件
                case R.id.popup_data_submit:
                    feedback_list_plan_data.setText(popup.getCurrentYear()+"-"+popup.getCurrentMonth()+"-"+popup.getCurrentDay());
                    break;
                // ....
            }
            //每次点击popupWindow中的任意按钮，记得关闭此popupWindow，
            popup.dismiss();
        }
    };
