Android沉浸式状态栏设计的实例代码

  public static void setStatusColor(Activity activity, int color) {    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {      //直接调用系统提供的方法 setStatusBarColor      activity.getWindow().setStatusBarColor(color);    } else if (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT) {      // 4.4 - 5.0 之间 采用一个技巧，首先把他弄成全屏，在状态栏的部分加一个布局      activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);      View view = new View(activity);      ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusbarHeight(activity));      view.setLayoutParams(params);      view.setBackgroundColor(color);      ViewGroup viewGroup = (ViewGroup) activity.getWindow().getDecorView();      viewGroup.addView(view);      // 获取activity中setContentView布局的根布局      ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content);      View activityView = contentView.getChildAt(0);      activityView.setFitsSystemWindows(true);    }  }  private static int getStatusbarHeight(Activity activity) {    Resources resources = activity.getResources();    int statusHeightId = resources.getIdentifier("status_bar_height", "dimen", "android");    return resources.getDimensionPixelOffset(statusHeightId);  }
