Android的XML选择器布局

问题描述

我想知道是否有一个选择的布局像有是可绘。

I was wanting to know if there is a selector for layouts like there is for drawables.

选择与绘制的例子：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected -->
<item android:drawable="@drawable/tab_library_clicked"
      android:state_selected="true" />
<!-- When not selected -->
<item android:drawable="@drawable/tab_library_not_clicked" />

但是，它可能有这样的事情（低于此code并没有为我工作，但它应该给你什么，我试图完成一个想法）：

But is it possible to have something like this (This code below didn't work for me but it should give you an idea of what I am trying to accomplish):

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected -->
<item android:layout="@layout/tab_library_clicked"
      android:state_selected="true" />
<!-- When not selected -->
<item android:layout="@layout/tab_library_not_clicked" />

推荐答案

我可能是错的，但我是pretty的肯定，这并不存在。

I might be wrong, but I'm pretty sure this doesn't exist.

最复杂，你就可以用XML一个选择做可能是使用的几可绘制合并到一个状态。

The most "sophisticated" you'll be able to do with a selector in XML probably is using a drawable layer list to combine several drawables onto one state.

另外，您可以尝试使用touch_down和touch_up事件以编程方式调用 setVisibility（）上的布局，但我想象中的表现会很差。

Alternatively you can try using the touch_down and touch_up events to programmatically call setVisibility() on the layouts, but I imagine the performance will be very poor.
