Android检测内部片段的触摸 [英] Android detecting on touch inside fragment

问题描述

我的活动中有两个片段. Fragment2与Fragment1重叠. Fragment1占据了整个屏幕.当用户点击Fragment1时，我希望Fragment2消失.

I have two fragments in my activity. Fragment2 overlaps Fragment1. And Fragment1 takes up the entire screen. When the user taps Fragment1 I would like Fragment2 to disappear.

我的问题是如何确定Fragment1被窃听了?

My question is how can I determine that Fragment1 was tapped?

Fragment1主要由一个Webview组成，我以为我可以使用它的setOnTouchListener，但似乎从未调用过它.

Fragment1 is mostly made up of a webview which I was thinking I could use its setOnTouchListener but it doesn't seem to ever be called.

任何建议将不胜感激.

Any suggestions would be appreciated.

这是我实现onTouchListener的方式:

This is how I implemented the onTouchListener:

1)首先，我实现了"OnTouchListener"

1) first I implemented "OnTouchListener"

public class Frag_ItemDetail extends Fragment implements OnTouchListener {

2)然后我覆盖了onTouch

2)then I overrode onTouch

@Override
public boolean onTouch(View v, MotionEvent event) {
Log.d("myclass", "onTouch"); 
return false;
}

3)然后将setOnTouchListener设置为我的webview

3) then I set the setOnTouchListener to my webview

WebView itemFullDescription = (WebView) v.findViewById(R.id.itemFullDescription);
WebView.setOnTouchListener(this); 

我在按钮上设置了onTouchListenerner，它工作正常.它只是不为webview工作.

I set the onTouchListenerner on a button and it worked fine. It just isnt' working for the webview.

推荐答案

我扩展了LinearLayout类并覆盖了onInterceptTouchEvent，因此，如果触摸Fragment1，Fragment2将会消失，这是可行的.

I extended the LinearLayout class and overrode onInterceptTouchEvent so if Fragment1 is touched Fragment2 would disappear, which is working.
