在res/drawable下
shape_address_blue.xml shape_address_gray.xml shape_address_green.xml shape_normal_blue.xml shape_address_orange.xml只需要把下面代码需要以下color即可
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<!--颜色-->
<solid android:color="@color/global_blue"/>
<!--给矩形加圆角-->
<corners android:radius="6dp"/>
</shape>
在res/values/colors.xml添加需求颜色值即可如
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#303F9F</color>
<color name="colorAccent">#FF4081</color>
<color name="red">#F00</color>
<color name="black">#000</color>
<color name="gray">#a000</color>
<color name="global_blue">#459FD7</color>
<color name="white">#fff</color>
<color name="light_gray">#cccccc</color>
<color name="light_green">#00ffa1</color>
</resources>
在res/values/style.xml中在resources节点下添加style
<!--归属地弹窗样式-->
<style name="AddressDialogStyle" parent="Theme.AppCompat.Dialog">
<!--去掉标题栏-->
<item name="android:windowNoTitle">true</item>
<!--去掉背景-->
<item name="android:windowBackground">@color/white</item>
<!--设置进入退出动画-->
<item name="android:windowAnimationStyle">@style/AddressAnimStyle</item>
</style>
<!--归属地弹窗动画-->
<style name="AddressAnimStyle">
<item name="android:windowEnterAnimation">@anim/anim_dialog_enter</item>
<item name="android:windowExitAnimation">@anim/anim_dialog_exit</item>
</style>
