android hover监控鼠标移动事件
public class HoverDemoActivity extends Activity { private Button btnBottom; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); btnBottom = (Button) findViewById(R.id.btn_bottom); btnBottom.setOnHoverListener(new OnHoverListener() { @Override public boolean onHover(View v, MotionEvent event) { int what = event.getAction(); switch(what){ case MotionEvent.ACTION_HOVER_ENTER: //鼠标进入view System.out.println("bottom ACTION_HOVER_ENTER"); break; case MotionEvent.ACTION_HOVER_MOVE: //鼠标在view上 System.out.println("bottom ACTION_HOVER_MOVE"); break; case MotionEvent.ACTION_HOVER_EXIT: //鼠标离开view System.out.println("bottom ACTION_HOVER_EXIT"); break; } return false; } }); } }
?当view隐藏时，无法监控点击，触摸和hover事件。
