1、图片设置背景选择器，以便点按或设置选中与否，背景切换
res/drawable/selector_settings_item_back.xml
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="true" android:drawable="@color/settingsSelectedItem"/> <item android:state_pressed="true" android:drawable="@color/settingsSelectedItem"/> <item android:state_selected="true" android:drawable="@color/settingsSelectedItem"/> <item android:state_focused="false" android:drawable="@color/settingsItem"/> </selector >
颜色值定义：
res/values/colors.xml
<?xml version="1.0" encoding="utf-8"?> <resources> <color name="settingsItem">#ffffff</color> <color name="settingsSelectedItem">#FFA500</color> </resources>
2、圆角按钮，按下抬起切换背景，同时切换文字颜色
res/layout/activity_xxx.xml
<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:background="@drawable/selector_shape_corner_button" android:text="审批中" android:textColor="@drawable/selector_font_style_corner_button" android:textSize="13sp" />
其中引用了 res/drawable/ 下的两个 selector ，
一个是背景图片随点按抬起状态进行切换，一个是文本颜色随点按抬起进行切换。
res/drawable/selector_shape_corner_button.xml
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="true" android:drawable="@drawable/shape_corner_button_fill"/> <item android:state_pressed="true" android:drawable="@drawable/shape_corner_button_fill"/> <item android:state_selected="true" android:drawable="@drawable/shape_corner_button_fill"/> <item android:state_focused="false" android:drawable="@drawable/shape_corner_button"/> </selector > res/drawable/selector_font_style_corner_button
shape_corner_button.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="5dp" />
<solid
android:color="#001da1f2" />
<stroke
android:width="1dp"
android:color="#1da1f2" />
</shape>
shape_corner_button_fill.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="5dp" />
<solid
android:color="#ff1da1f2" />
<stroke
android:width="1dp"
android:color="#1da1f2" />
</shape>
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:color="#ffffff"/>
<item android:state_pressed="true" android:color="#ffffff"/>
<item android:state_selected="true" android:color="#ffffff"/>
<item android:state_focused="false" android:color="#1da1f2"/>
</selector >
