为什么当另一个布局覆盖它时，按钮可以点击？(Why is a button clickable when theres another layout overlaying it?)

为什么当另一个布局覆盖它时，按钮可以点击？(Why is a button clickable when theres another layout overlaying it?)

我得到了一个相对定位的布局。 其中我得到了（现在）两件事情：

绑定到onClick事件的可点击按钮 覆盖整个屏幕的LinearLayout

虽然LinearLayout覆盖了按钮，但按钮仍然是可点击的。 即使叠加层中有另一个按钮。

我怎样才能避免这种情况？

I got a Layout which is relatively positioned. In it I got (by now) two things:

A Clickable Button which is bound to an onClick-Event A LinearLayout which is overlaying the full screen

Although the LinearLayout is overlaying the button, the button is still clickable. Even if there's another button in the overlay.

How can I avoid this?

最满意答案

覆盖视图（和布局）必须实现onClick侦听器才能捕获事件，否则事件将在底层视图上分派。

Alright I found an approach that works together with animation:

The Layout (shortened):

<RelativeLayout ...> <Button ... /> <LinearLayout android:id="@+id/underlay" android:background="#00ffffff" /> <LinearLayout android:id="@+id/overlay" ... /> </RelativeLayout>

Now when Fading In "overlay" it seems to be the best to have an invisible "underlay" which is immediately put to VISIBLE:

LinearLayout underlay = (LinearLayout)findViewById(R.id.underlay); underlay.setVisibility(View.VISIBLE); underlay.setOnClickListener(...); //now animate the overlay
