ProgressBar (进度条)
例 : <ProgressBar android:id="@+id/pBar"
Style="?Android:attr/progressBarStyleHorizontal" -- 水平方向的进度条
Android:layout_width="200dp"
Android:layout_height="wrap_content"
Android:visibility="gone"
Android:max=200
/>
代码 : 1 . 声明变量
2 . 根据ID取得控件对象 findViewById
3 . 设置监听类
Class ButtonLinstener implements OnClickListener {
Public void onClick(View v) {
If (i == 0) {
pBar.setVisibility(View.VISIBLE);
}
Else if ( i < pBar.getMax() ) {
pBar.setProgress(i); -- 设置主进度条的当前值
pBar.setSecondaryProgress(i+10); -- 设置第二进度条的当前值
}
Else {
pBar.setVisbility(View.GONE);
}
I = i + 10;
}
}
4 . 绑定事件
myButton.setOnClickListener(new ButtonLinstener());
例 : main布局文件
<ListView android:id="@id/android:list"
Android:layout_width="fill_parent"
Android:layout_height="wrap_content"
Android:drawSelecrorOnTop = "false"
Android:scrollbars="vertical" />
User布局文件略 (两个TextView)
代码 : public class Activity extends ListActivity {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// 用一个集合对象装数据
ArrayList<HashMap<Stirng,String>> list = new ArrayList<HashMap<Stirng,String>>();
HashMap<String,String> Map1 = new HashMap<String,String>();
HashMap<String,String> Map2 = new HashMap<String,String>();
HashMap<String,String> Map3 = new HashMap<String,String>();
Map1.put("user_name","zhangsan");
Map1put("user_ip","192.168.0.1");
Map2.put("user_name","lisi");
Map2.put("user_ip","192.168.0.2");
Map3.put("user_name","wangwu");
Map3.put("user_ip","192.168.0.3");
List.add(Map1);
List.add(Map2);
List.add(Map3);
// listActivity对象 , map , 第二个布局文件 , 对应hashMap的值对(可想象成列) , 控件显示的位置
SimpleAdapter listAdapter = new SimpleAdapter(this , list , R.layout.user , new String[] {"user_name","user_ip"} , new int[] {R.id.user_ip,R.id.user_name});
setListAdapter(listAdapter);
}
// 重写
Protected void onListItemClick(ListView lv , View v , int position , long id) {
super.onListItemClick(1, v , position , id);
System.out.println("id--------" + id);
System.out.println("position-------" + position)
}
