问什么selector没有出现效果？求大神 啊
调用的时候：android:background="@drawable/selector"
- HTML code
<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_btn_bg_f" /> <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_btn_bg_f" /> <item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_btn_bg_f" /> <item android:state_pressed="true" android:drawable="@drawable/tab_btn_bg_f" /> <item android:drawable="@drawable/tab_btn_bg"/></selector>
------解决方案--------------------
没效果是只显示tab_btn_bg_f这张还是tab_btn_bg这张？
写这么复杂真心用的着么？
------解决方案--------------------
使用的不对吧
------解决方案--------------------
最简单的，
<?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/spinner_dropdown_pressed" />
<item android:state_focused="true" android:drawable="@drawable/spinner_dropdown_pressed" />
<item android:drawable="@drawable/spinner_dropdown_normal" />
</selector>
这样试试
