Android linearlayout click to dynamically change the background

You may want this effect when using linearlayout:

<? XML version = "1.0" encoding = "UTF-8"?>
<Selector xmlns: Android = "http://schemas.android.com/apk/res/android">
<Item Android: state_focused = "true" Android: drawable = "@ drawable/buttonbackgroundselected"/>
<Item Android: state_pressed = "true" Android: drawable = "@ drawable/buttonbackgroundselected"/>
<Item Android: state_focused = "false" Android: drawable = "@ drawable/buttonbackgroundnormal"/>
</Selector>

However:

<Linearlayout
Android: layout_width = "fill_parent" Android: layout_height = "wrap_content"
Android: Background = "@ drawable/buttonbackground"
>

After you do this, you will find that even if you touch linearlayout with your hands, the rest will not dynamically change the background color as you lock your mind, how can this problem be solved?

The solution is actually very simple,Directly add the property: Android: clickable = "true ".

Because the default linearlayout cannot be clicked, related events cannot be passed to linearlayout. After this attribute is added, the background of linearlayout can be dynamically changed.
