今天打开Android studio突然出现了setContentView(R.layout.activity_main);中的R标红错误，这已经不是第一次出现这个错误了，真心的觉得Android studio是真的不稳定，找了半天发现我的资源文件res下面的好多文件出现了乱码，（我也是醉了）。把他们一个一个的替换成正确的代码终于rebulid project不再出现错误了。

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

<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">

    <background android:drawable="@drawable/ic_launcher_background" />

    <foreground android:drawable="@drawable/ic_launcher_foreground" />

</adaptive-icon>

这是mipmap下的ic_lanucher和ic_lanucher_round通用的代码。
