Answer 1

如果你从ListActivity扩展你的列表视图，那么下面将会帮助你。

onListItemClick：

@Override 
protected void onListItemClick(ListView l, View v, int position, long id) { 
    String item = (String) getListAdapter().getItem(position); 
    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show(); 
} 

的onkeydown：

@Override 
    public boolean onKeyDown(int keyCode, KeyEvent event) { 
    super.onKeyDown(keyCode, event); 
     switch(keyCode) 
     { 
      case KeyEvent.KEYCODE_CAMERA: 
      Toast.makeText(ListViewActivity.this, "Pressed Camera Button", Toast.LENGTH_SHORT).show(); 
       return true; 
      case KeyEvent.KEYCODE_1: 
      Toast.makeText(ListViewActivity.this, "Pressed 1", Toast.LENGTH_SHORT).show(); 
       return true; 
      case KeyEvent.KEYCODE_HOME: 
      Toast.makeText(ListViewActivity.this, "Pressed Home Button", Toast.LENGTH_SHORT).show(); 
       return true; 

      case KeyEvent.KEYCODE_BACK: 
      Toast.makeText(ListViewActivity.this, "Pressed Back Button", Toast.LENGTH_SHORT).show(); 
       finish(); 
       return true; 
     } 

     return false; 
    }

使用这个类

public class CustomListView extends ListView { 

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

@Override 
public boolean dispatchKeyEvent(KeyEvent event) { 
    if ((KeyEvent.KEYCODE_DPAD_UP == event.getKeyCode() || KeyEvent.KEYCODE_DPAD_DOWN == event.getKeyCode())) { 
     //handle key events here 
    } 
    return false; 
} 

}
