Android 自定义ToolBar并沉浸式

  ToolBar是Android 5.0推出的一个新的导航控件用于取代之前的ActionBar,由于其高度的可定制性、灵活性、具有Material Design风格等优点,越来越多的App也用上了ToolBar。
  沉浸式状态栏是从android Kitkat(Android 4.4)开始出现的,它可以被设置成与APP顶部相同的颜色,这就使得切换APP时,整个界面就好似切换到了与APP相同的风格样式一样。

依赖包:

  Toolbar, implementation 'androidx.appcompat:appcompat:1.1.0'
  沉浸式, implementation 'com.gyf.immersionbar:immersionbar:3.0.0'

1、自定义Toolbar步骤:

1)、定义 /values/styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="TextAppearance_TitleBar_Title" parent="TextAppearance.AppCompat.Toolbar.Title">
    ...
    </style>

    <style name="TextAppearance_TitleBar_subTitle" parent="TextAppearance.AppCompat.Toolbar.Subtitle">
      ....
    </style>
</resources>

2)、自定义toolbar 继承 androidx.appcompat.widget.Toolbar

public class CustomToolBar extends Toolbar {
    private TextView mCenterTitle;
    private ImageView mCenterIcon; //中心icon
    private TextView mLeftText;
    private ImageButton mLeftIcon; 
    private TextView mSettingText;
    private ImageButton mSettingIcon;

    public CustomToolBar(Context context) {
        super(context);
    }

    public CustomToolBar(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomToolBar(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

  
    public void setLeftText(@StringRes int id) {
        setLeftText(this.getContext().getText(id));
    }

  
    public CustomToolBar setLeftText(CharSequence text) {
        Context context = this.getContext();
        if (this.mLeftText == null) {
            this.mLeftText = new TextView(context);
            this.mLeftText.setGravity(Gravity.CENTER_VERTICAL);
            this.mLeftText.setSingleLine();
//            this.mLeftText.setEllipsize(TextUtils.TruncateAt.END);
            setLeftTextAppearance(getContext(), R.style.TextAppearance_TitleBar_subTitle);
            //textView in left
//            this.addMyView(this.mLeftText, Gravity.START);
            int i = dp2px(this, 16);
            this.addMyView(this.mLeftText, Gravity.START, 0, 0, i, 0, 48);

        if (mCenterTitle != null) {
            ((View) mCenterTitle.getParent()).setOnClickListener(listener);
        }
    }
}

2、自定义Toolbar使用

1)、res/layout创建布局文件

      <?xml version="1.0" encoding="utf-8"?>
frameLabelStart--frameLabelEnd 

2)、在布局中使用

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:binding="http://schemas.android.com/tools">
    <data>
        <variable
            name="viewModel"
            type="com.android.playandroid.viewmodel.LoginViewModel" />
    </data>
    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/bkg"
        android:orientation="vertical">

        <include
            layout="@layout/title_layout"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintTop_toTopOf="parent" />
         ...
    </androidx.constraintlayout.widget.ConstraintLayout>

</layout>

3)、代码中使用

##### a、初始化:

    mBinding.root.toolbar.setNavigationIcon(R.mipmap.register_close)
    mBinding.root.toolbar.setMyCenterTitle(getString(R.string.register), true)
    mBinding.root.toolbar.setMySettingText(getString(R.string.login))

##### b、点击事件:

   mBinding.root.toolbar.setNavigationOnClickListener {
        ....
    }
    mBinding.root.toolbar.setSettingTextOnClickListener {
       ...
}

4)、沉浸式,设置toolbar背景颜色、文字颜色,一般写在基类

 protected open fun initImmersionBar() {
        //在BaseActivity里初始化
        mImmersionBar = ImmersionBar.with(this)
        if (toolbar != null) {
            mImmersionBar.titleBar(toolbar)
        }
        mImmersionBar.statusBarDarkFont(true)
    //    mImmersionBar.keyboardEnable(true).navigationBarWithKitkatEnable(false).init()
      //  mImmersionBar.init()
        
       ImmersionBar.with(this).init()
    }

注意:

1、配置整个app的toolbar风格,在/value/styles.xml文件修改代码

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    
        <item name="colorPrimary">@android:color/white</item>
        <item name="colorPrimaryDark">@android:color/white</item>
        <item name="colorAccent">@android:color/white</item>

      ...

    </style>

#### 2、修改了 toolbar的高度 ,怎么让navigationIcon显示在toolbar中心?
  只要设置如下,即可:android:minHeight="@dimen/toolbar_height"

3、toolbar布局文件位置

  如果在commonlibrary目录创建该文件,在app 下还需要复制一份,因为在app 使用toolbar,kotlin-android-extensions引用不到commonlibrary目录下的布局文件。
