Question

我在drawable文件夹上有一系列图像，我想在语言文件夹（drawable-pt）中重复使用，所以我为语言文件夹中的每个图像创建了一个xml文件，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/habitat_over" />

然后我在xml文件夹中有一个表示按钮状态的xml文件：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
            android:drawable="@drawable/habitat_over"/>
    <item android:drawable="@drawable/habitat" />
</selector>

在布局中我有这样的东西：

<ImageButton android:layout_weight="1" 
android:background="@null" 
android:layout_width="wrap_content" 
android:src="@xml/habitat_button" 
android:id="@+id/habitat" 
android:layout_height="wrap_content" 
android:scaleType="fitCenter">
</ImageButton>

它应该可以工作但是当我运行应用程序时会出现此错误：

有谁知道为什么会这样？

提前致谢!!

即使没有真正记录，android:src的{{1}}属性也只接受图像文件（不是用XML定义的drawable）。

不要在位图中使用<bitmap>并从布局中引用src="@drawable/habitat_over"，而是移除<bitmap>并从布局添加直接引用到<bitmap>。< / p>

调用XML drawables的XML按钮
