在res/anim文件下新建alpha_in.xml

<?xml version="1.0" encoding="utf-8"?>

<alpha xmlns:android="http://schemas.android.com/apk/res/android"

       android:duration="1000"

       android:fromAlpha="0.0"

       android:toAlpha="1.0"

    >

</alpha>

在res/layout文件下新建activity_custom_loding_dialog_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
