首先直接～直接～直接拷贝ImmersiveStatusBar类，完全解耦，里面方法很多，但是常用的有三个，将在文章最后举例给出。
/**
本工具类作为//www.greatytc.com/p/e14db8a794de文章中的小标题2：ImmersionBar类的一个补充工具使用，因ImmersionBar的使用，会使得输入法将布局顶起引起遮盖EditText的情况，故如遇此情况，使用本工具类（本方法也可以独立使用于6.0以上机型）。一般情况（大约九成以上）的状态栏问题依然建议使用ImmersionBar。
*/
别看方法多，二话不说直接从下方开始复制：
public class ImmersiveStatusBar {
private Activity mActivity;
public ImmersiveStatusBar(Activity activity) {
this.mActivity = activity;
}
