Question

我有4个钮扣，我在每个按钮上设置了一个图像作为背景。我想要做的是，未选中时按钮应变为灰色并在选择时变成原始图像颜色。我怎么能这样做？

为什么不使用切换按钮？

创建一个xml名称like_button.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:state_pressed="true" android:drawable="@drawable/likeactivepressed" />
    <item android:state_pressed="true" android:drawable="@drawable/likeinitialpressed"/>
    <item android:state_checked="true" android:drawable="@drawable/likeon"/>
    <item android:drawable="@drawable/likeinitial"/>
</selector>

然后在你的按钮中定义它

 android:background="@drawable/like_button"
