Question

安卓listview长按时的由黄到透明渐变色怎么改变成由蓝到透明？

Answer 1

给item的根布局增加一个背景选择器
selector

具体代码
将会以下文件保存到drawable目录中, 然后到item的根目录中调用android:background="@drawable/xxx"

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>
<solid android:color="#9AD6F0"/>

</shape> <!-- <stroke android:width="0.1dp" android:color="#333333"/> -->
</item>

<item android:state_selected="true" >
<shape>
<solid android:color="#9AD6F0"/>
</shape>
</item>

<item android:state_focused="true" >
<shape>
<solid android:color="#9AD6F0"/>
</shape>
</item>

<item>
<shape>
<solid android:color="#00000000"/>
</shape>
</item>

</selector>
