自定义Drawable（文字按钮点击效果设置）

一些在开发UI时经常需要用到的自定义Drawable的代码，整理起来，方便今后高效的开发。

1，单选按钮、复选框

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@mipmap/icon_checked" android:state_checked="true"></item>
    <item android:drawable="@mipmap/icon_normal"></item>
</selector>

2，View的点击效果

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@mipmap/btn_shake_colour_down" android:state_selected="true" />
    <item android:drawable="@mipmap/btn_shake_colour_down" android:state_focused="true" />
    <item android:drawable="@mipmap/btn_shake_colour_down" android:state_pressed="true" />
    <item android:drawable="@mipmap/btn_shake_colour_nor" />
</selector>

3，Shape做背景

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
   <solid android:color="#991C203A"/>
    <stroke android:width="1dp" android:color="#AAFFFFFF"/>
    <padding android:bottom="10dp" android:left="10dp" android:right="10dp" android:top="10dp"/>
</shape>

4，Shape和Selector合成按钮点击效果，注：<item>一定要在<item android:state_******="true">之后，否则设置无效果

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true">
        <shape>
            <solid android:color="#11000000" />
            <stroke android:width="1dp" android:color="#88FFFFFF" />
        </shape>
    </item>
    <item android:state_pressed="true">
        <shape>
            <solid android:color="#11000000" />
            <stroke android:width="1dp" android:color="#88FFFFFF" />
        </shape>
    </item>
    <item>    
        <shape>
            <solid android:color="#00000000" />
            <stroke android:width="1dp" android:color="#AAFFFFFF" />
        </shape>
    </item>
</selector>

5，TextView文字点击时变色，将该文件放到 /res/color 

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:color="@color/common_font_check_white" />
    <item android:state_focused="true" android:color="@color/common_font_check_white" />
    <item android:state_pressed="true" android:color="@color/common_font_check_white" />
    <item android:color="@color/white" />
</selector>
