还是以自定义的TestButton为例。

我们可以通过重写onTouchEvent方法来处理诸如down move up的消息：

public class TestButton extends Button {

	public TestButton(Context context) {

		super(context);

		// TODO Auto-generated constructor stub

	}

	public TestButton(Context context, AttributeSet attributeSet) {

		super(context, attributeSet);

		// TODO Auto-generated constructor stub

	}

	@Override

	public boolean onTouchEvent(MotionEvent event) {

		boolean value = super.onTouchEvent(event);

		System.out.println("super.onTouchEvent: " + value+ " event: " + event.getAction());

		return value;

	}

也可以通过实现OnTouchListener的接口，然后设置TestButton的onTouchListener可以达到同样的目的

    class OnTouchListenerTest implements View.OnTouchListener{

		@Override

		public boolean onTouch(View v, MotionEvent event) {

			return false;

		}

    }

        TestButton b = (TestButton)findViewById(R.id.button);

        OnTouchListenerTest listener = new OnTouchListenerTest();

        b.setOnTouchListener(listener);

但上述两种监听有什么区别呢？

先看一下Android源码中对于View中dispatchTouchEvent的实现：

//源码：
	public boolean dispatchTouchEvent(MotionEvent event){

		... ...

		if(onFilterTouchEventForSecurity(event)){

			ListenerInfo li = mListenerInfo;

			if(li != null && li.mOnTouchListener != null && (mViewFlags & ENABLED_MASK) == ENABLED

				&& li.mOnTouchListener.onTouch(this, event)) {

				return true;

			}

			if(onTouchEvent(event)){

				return true;

			}

		}

		... ...

		return false;

	}

可以看到onTouchListener的接口的优先级是要高于onTouchEvent的，假若onTouchListener中的onTouch方法返回true，

表示此次事件已经被消费了，那onTouchEvent是接收不到消息的。

因为Button的performClick是利用onTouchEvent实现，假若onTouchEvent没有被调用到，那么Button的Click事件也无法响应。

综合来讲：

onTouchListener的onTouch方法优先级比onTouchEvent高，会先触发。

假如onTouch方法返回false会接着触发onTouchEvent，反之onTouchEvent方法不会被调用。

内置诸如click事件的实现等等都基于onTouchEvent，假如onTouch返回true，这些事件将不会被触发。

    }

    class OnTouchListenerTest implements View.OnTouchListener {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Log.i("我是onTouch","onTouch");
            return false;
        }

    }
