How can I disable all touch events on all children of a ViewGroup?
android, android-viewpager, onclick, scrollview, webview
Solution
May be I have misunderstood something, but I guess the answer to your question is very simple: If you don't want to dispatch none of the touch events to the children - so you just need to override `ViewGroup.onInterceptTouchEvent (MotionEvent ev)` API reference like this:
public boolean onInterceptTouchEvent (MotionEvent ev){
return true;
}
According to the android documentation this means that your ViewGroup will always intercept all the touch events and don't dispatch them to the children. All of them will be directed to the `ViewGroup.onTouchEvent(MotionEvent ev)` method of your ViewGroup.
Problem
I've got a `FrameLayout` container containing many things (including `ScrollView`, `WebView`, `ViewPager`...). I would like to be able to trigger the onClick event on this container, but it seems that some of `ScrollView`, `WebView` and `ViewPager` intercept the touch event, because the onClick event is only triggered when I click on the parts of the container that do not have any of them... How can I disable all touch events on the container's children in order to be able to trigger onClick anywhere in it? UPDATE The idea is to have something like the task manager in Android 3.2, i.e. where the current visible screen of the app is shown as a reduced icon, that can be clicked. Thanks
