添加到values-v19：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="TranslucentTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowTranslucentNavigation">true</item>
    </style>
</resources>

Error:Execution failed for task ':app:mergeDebugResources'.

D:AndroidDatademoTuMusicappsrcmainresvalues-v19styles.xml:
Error: In DataSet 'main', no data file for changedFile.
This is an internal error in the incremental builds code;
to work around it, try doing a full clean build.

我改用了StatusBarUtil
