[移动开发]Android 仿通话来电界面

Android 仿通话来电界面

简介： 开发中需要模拟来电时的通话界面，仿照来电界面实现来电时播放铃声，界面通过动画模拟来电动效。

效果图：

1. 自定义图片背景，图片由小变大的动态效果。
   shap_circle.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <corners android:radius="65dp"/>
    <solid android:color="#31DE87"/>

</shape>

2. 布局文件activity_my_call.xml
