title: 設(shè)置背景比較器失敗

• 錯(cuò)誤：<item> tag requires a 'drawable' attribute or child tag defining a drawable

設(shè)置背景選擇器的時(shí)候像常用的那樣

<?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>

就會(huì)報(bào)錯(cuò)，目前只有在設(shè)置背景的時(shí)候碰到過。

• 解決辦法

好吧，提示說我少drawable的話。。那么在colors.xml里面把<color>標(biāo)簽替換成<drawable>標(biāo)簽

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

然后將選擇器改成

<?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.
