本文解决了一个在Android开发中常见的日志警告：app:theme被标记为已弃用，并建议使用android:theme代替。通过更改布局文件中的主题属性，可以消除此警告。

Android开发中日志显示：
01-19 15:14:52.148 3118-3118/com.seehow.stmaker I/AppCompatViewInflater: app:theme is now deprecated. Please move to using android:theme instead.

由于布局中用了

app:theme="@style/NavigationDrawerStyle"

修改为android:theme="@style/NavigationDrawerStyle"后即可。
