 */  
private void initStatusBarColor() {  
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {  
        Window window = getWindow();  
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);  
        window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN  
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);  
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);  
        window.setStatusBarColor(Color.TRANSPARENT);
