问题描述

在此处输入图像说明

我的活动中有两个片段. Fragment2重叠片段1. Fragment1占用整个屏幕.当用户点击Fragment1时，我希望Fragment2消失.

我的问题是如何确定fragment1被轻拍?

fragment1主要由一个网络视图组成，我认为我可以使用它的setOntouchListener，但似乎从未被称为.

任何建议都将不胜感激.

这就是我实现OnTouchListener的方式:

1)首先我实施了" OnTouchListener"

public class Frag_ItemDetail extends Fragment implements OnTouchListener {

2)然后我覆盖了OnTouch

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

3)然后，我将setOntouchListener设置为我的WebView

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

我将OnTouchListenerner设置在一个按钮上，它工作正常.它只是对WebView不起作用.

您的返回false不应该返回true吗?如果触摸了活动2(或WebView)，则应以true返回.或VICE反之亦然

问题描述

enter image description here

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.

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

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.

Any suggestions would be appreciated.

This is how I implemented the onTouchListener:

1) first I implemented "OnTouchListener"

public class Frag_ItemDetail extends Fragment implements OnTouchListener {

2)then I overrode onTouch

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

3) then I set the setOnTouchListener to my webview

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

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

Shouldnt your return false be return true? If activity 2 is touched(or the webview) it should be returning as true. or vice versa
