为什么我的片段的ontouch（）和的onClick（）方法仍然响应时，它已经开始另一frament [英] Why my fragment's ontouch() and onClick() method still response when it has started another frament

问题描述

我的应用程序有一个片段A和B片段，该片段A包含一个 GridView控件和的ListView 象下面这样

My app has a fragment A and fragment B, the fragment A contains a GridView and a ListView like below:

             fragment A
-------------------------------------
|                       |            |
|                       |            |
|                       |            |
|        GridView A     | ListView A |
|                       |            |
|                       |            |
|                       |            |
|                       |            |
|                       |            |
--------------------------------------

和片段B包含一个的ListView 和的LinearLayout 如下：

and the fragment B contains a ListView and a LinearLayout as below:

--------------------------------------
|            |                       |
|            |                       |
|            |                       |
|            |                       |
| ListView B |     LinearLayout B    |
|            |                       |
|            |                       |
|            |                       |
|            |                       |
|            |                       |
--------------------------------------

在单击的ListView 的片段A A的项目时，将启动B片段，并显示该项目的详细信息。但在B片段，当我触摸这曾经是的GridView领域的屏幕 A或的ListView A，它还是响应 GridView控件 A的onTouch（）方法或的ListView A的的onClick（）方法。这是我第一次用片段，我已经混淆这一段时间孤独

When a click a item of ListView A on fragment A, it will start fragment B and shows the details information of the item. But at the fragment B when I touch the screen which used to be the area of GridView A or ListView A, it still response the GridView A's onTouch() method or ListView A's onClick() method. This is the first time I used Fragment, I have confusing this for a lone time.

推荐答案

这听起来像触摸被通过对第一个片段泄漏。我将在B片段的根布局，以prevent从经历时，它的布局是可见触摸设置onTouch监听器。

It sounds like the touches are leaking through to the first fragment. I would set a onTouch Listener on the root layout of fragment B to prevent the touches from going through when its layout is visible.

因此​​，对于这些方针的东西：

So for something along these lines:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
     View root = inflater.inflate(R.layout.fragmentBlayout, container, false);
    root.setOnTouchListener(new OnTouchListener()
    {
        @Override
        public boolean onTouch(View v, MotionEvent event)
        {
        /** Intercepts touches from going through. */
        return true;
        }
    });

    /** Find the rest of your views... */

   return root;
}
