描述：
由于产品需求，要求含有EditText的界面全屏显示，最好的解决方式是使用AndroidBug5497Workaround.assistActivity(this)
的方式来解决，但是华为和魅族手机系统自带的有底部导航栏，会造成一些布局被遮挡。
解决方案：在values-21的style.xml中添加android:windowDrawsSystemBarBackgrounds”并将值设置为false，方式如下
在style引用的主题里面加入android:windowDrawsSystemBarBackgrounds”并将值设置为false，会自动提醒点击alt+Enter会新建values-21的文件夹并生成styles.xml的文件。
也可以自己忽略的，直接新建values-21的文件夹然后新建一个styles.xml的文件，将主题里面的内容复制到styles.xml里面然后加上加入android:windowDrawsSystemBarBackgrounds”并将值设置为false即可解决。
例外：附上（网上找到的）
