状态栏完美四个重要代码

//去掉信息栏

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

//信息栏背景为透明，这时内容占据信息栏，但有文字

public static void setImgTransparent(Activity activity){
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Window window = activity.getWindow();
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                    | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setStatusBarColor(Color.TRANSPARENT);
            window.setNavigationBarColor(Color.TRANSPARENT);
        }
    }

信息栏高度，即使去掉信息栏以及背景为透明也是原来高度

public static int getStatusBarHeight(Context context) {
        // 获得状态栏高度
        int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
        return context.getResources().getDimensionPixelSize(resourceId);
    }

设置状态栏文字颜色黑或白

/**
     * 设置状态栏文字颜色黑或白
     * @param window
     * @param lightStatusBar
     */
    public static void fontColor(Window window,boolean lightStatusBar){
        View decor = window.getDecorView();
        int ui = decor.getSystemUiVisibility();
        if (lightStatusBar) {
            ui |=View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR; //设置状态栏中字体的颜色为黑色
        } else {
            ui &= ~View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR; //设置状态栏中字体颜色为白色
        }
        decor.setSystemUiVisibility(ui);
    }

 

完美！！！，如果要设置颜色请自行百度
