Android的：在设置里面onTouchListener为RelativeLayout的颜色 [英] Android: setting colors for relativelayout inside onTouchListener

问题描述

我有一些RelativeLayout的，其内部有多个TextView的和imagebuttons，所以为了不使 onTouchListener 一个接一个，我已经实现了低于code：

I am having some relativeLayout, inside which there are multiple textview and imagebuttons, so in order not to making onTouchListener one by one, I have implemented the below code:

    relative1.setOnTouchListener(new OnTouchListener() 
    {
        @Override
        public boolean onTouch(View arg0, MotionEvent event) 
        {
            if(event.getAction()==MotionEvent.ACTION_DOWN )
            {
                relative1.setBackgroundColor(getResources().getColor(R.color.tran_black));
            }

            if((event.getAction()==MotionEvent.ACTION_UP || event.getAction()==MotionEvent.ACTION_CANCEL))
            {
                relative1.setBackgroundColor(getResources().getColor(android.R.color.transparent));
            }
            return false;
        }           
    }); 

问：

的 relative1 RelativeLayout的已转向 tran_black 颜色当pressed，但它不能在 Action_up 回头透明。

Question:

The relative1 RelativeLayout has turned to tran_black color when pressed, but it fails to turn back to transparent upon Action_up.

怎么可能ameneded？谢谢！

How could that be ameneded? Thanks!

推荐答案

就返回真正而不是假。

据<一个href=\"http://developer.android.com/reference/android/view/View.OnTouchListener.html#onTouch%28android.view.View,%20android.view.MotionEvent%29\"相对=nofollow> onTouch方法DOC ，返回值为 True如果听者已经消耗的情况下，否则为false。
这意味着，当你返回false，连续的事件将不会被传递到您的收听。

According to onTouch method doc, the return value is True if the listener has consumed the event, false otherwise. This means that when you return false, successive events will not be passed to your listener.

您也可以参考我的答案<一个href=\"http://stackoverflow.com/questions/17291027/ontouch-events-not-working-properly/17291426#17291426\">here其中有意见的例子。
