android-调用XML可绘制对象的XML按钮

我想在语言文件夹(drawable-pt)中重用可绘制文件夹上的一系列图像,因此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吗？

提前致谢！！

解决方法:

即使没有真正记载,也可以将< bitmap>的android：src属性仅接受图像文件(不接受XML定义的可绘制对象).

而不是在位图中包含src =“ @ drawable / habitat_over”并引用该< bitmap>从您的布局中删除< bitmap>并将直接引用从布局添加到@ drawable / habitat_over.
