Android Button事件处理

一般只需要处理按钮的点击事件就可以，但想让一个按钮处理多个事件，就得同时监听多个方法。

OnClickListener  点击事件

OnLongClickListener 长按事件

OnTouchListener  触摸事件

同事监听三个事件，只有 OnTouchListener  会被触发。

public class TestButtonActivity extends Activity
{
    Button test = null;
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        test = (Button) findViewById(R.id.test);

        test.setOnClickListener(new MyOnClickListener());
        test.setOnLongClickListener(new MyOnLongClickListener());
        test.setOnTouchListener(new MyOnTouchListener());
    }

    class MyOnClickListener implements OnClickListener
    {
     @Override
     public void onClick(View v)
     {
     Toast.makeText(getApplicationContext(), "单击事件", Toast.LENGTH_SHORT).show();
     }

    }

   class MyOnLongClickListener implements OnLongClickListener
   {  

@Override
public boolean onLongClick(View v)
{
Toast.makeText(getApplicationContext(), "长按事件", Toast.LENGTH_SHORT).show();
return true;
}

   }

   class MyOnTouchListener implements OnTouchListener
   {

@Override
public boolean onTouch(View v, MotionEvent event)
{
if (event.getAction() == MotionEvent.ACTION_DOWN)
{

Toast.makeText(getApplicationContext(), "按下按钮事件", Toast.LENGTH_SHORT).show();
}  

if (event.getAction() == MotionEvent.ACTION_UP)
{
Toast.makeText(getApplicationContext(), "弹起按钮事件", Toast.LENGTH_SHORT).show();

}

               //返回true  表示事件处理完毕，会中断系统对该事件的处理。false 系统会同时处理对应的事件
return true;
}
   }
}
