Pass touches to the view under

问题

In my app I have a fragment on top of the activity. The fragment is filling the whole screen. Part of the fragment is a transparent View and you can see the views under (that belong to the activity). Is there a way to transfer the touch events to the views that are under the transparent View of the fragment? Thanks!

回答1:

In your overriden onTouchEvent method inside the fragment return false, it passes the touch event to the lower layer views.

simplest way :

Declare your fragment not clickable / focusable by using

android:clickable="false"
android:focusable="false"

or

v.setClickable(false)
v.setFocusable(false).

The click events should be dispatched to the fragment's parent now.

Note: In order to achieve this, you have to add click to its direct parent. or set android:clickable="false" and android:focusable="false" to its direct parent to pass listener to further parent.

You can use special flag in layoutParams.
