• 错误：<item> tag requires a 'drawable' attribute or child tag defining a drawable

设置背景选择器的时候像常用的那样

1
2
3
4
5
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:color="@color/leftmenu_pressed"  />
    <item android:color="@color/leftmenu_bg" />
</selector>

就会报错，目前只有在设置背景的时候碰到过。

  • 解决办法

好吧，提示说我少drawable的话。。那么在colors.xml里面把<color>标签替换成<drawable>标签

1
2
<drawable name="leftmenu_pressed">#0f0f0f</drawable>
<drawable name="leftmenu_bg">#141414</drawable>

然后将选择器改成

5
<?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/leftmenu_pressed"  />
    <item android:drawable="@drawable/leftmenu_bg" />
</selector>

就好了.
