TextView textView;
        ViewGroup view;
        @Override
        protected void onCreate(@Nullable Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            if (android.os.Build.VERSION.SDK_INT > 18) {
                Window window = getWindow();
    //设置StatusBar为透明显示,需要在setContentView之前完成操作
                window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            }
    
            setContentView(getResultId());
            // 创建TextView用于叠加StatusBar的颜色块
            textView = new TextView(this);
            LinearLayout.LayoutParams lParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,getStatusHeight());//在此指定宽高
            textView.setBackgroundColor(Color.parseColor("#ff6219"));//在此指定颜色
            textView.setLayoutParams(lParams);
            // 获得根视图并把TextView加进去。
            view = (ViewGroup) getWindow().getDecorView();
            view.addView(textView);
            initView();
            initListener();
            initData();
        }
    在填充布局（setContentView）之前填充状态栏，安卓4.4（api19）支持
    //设置窗体全屏
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    //设置窗体始终点亮
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
          WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    //设置窗体背景模糊
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,                
            WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
    当向fragmet添加导航栏时不会发生重叠，当向activity添加导航栏时会被状态栏遮挡在下方
    获取状态栏高度的两个方法：
    1.通过获取到status_bar_height的资源id，在计算其高度
     
    public int getStatusBarHeight（）{
    int height =0;
    Int resourceId=getResources().getIdentifier(“status_bar_height”,”dimen”,”android”);
    if(resourceID>0){
    height=getResources().getDiensionPixelSize(resourceId);
    }
    return height;
    }

2.通过反射
    Public static int getStatusHeight(){
    Int statusHeight=-1;
    Try{
    Class(?) clazz=Class.forName(“com.android.internal.R$dimen”);
    Object object=clazz.newInstance();
    Int height=Integer.parseInt(clazz.getField(“status_bar_height”).get(object).toString());
    statusHeight=context.getResource().getDiensionPixelSize(height);
    }catch(Exception e){
    E.ppppppp();}
    Return statusHeight;
    }
