ImmersiveStatusBar修改状态栏背景色和图标颜色工

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http://www.jianshu.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;
}
/**

*/

window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION

window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.TRANSPARENT);
window.setNavigationBarColor(Color.TRANSPARENT);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window window = activity.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
