一、沉浸式状态栏（没有状态栏了）

沉浸式状态栏

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);
        }
    }

二、半透明状态栏

半透明状态栏

 static void translucentStatusBar(Activity activity) {
        Window window = activity.getWindow();
        //设置Window为透明
        window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

        ViewGroup mContentView = (ViewGroup) activity.findViewById(Window.ID_ANDROID_CONTENT);
        View mContentChild = mContentView.getChildAt(0);

        //移除已经存在假状态栏则,并且取消它的Margin间距
        removeFakeStatusBarViewIfExist(activity);
        removeMarginTopOfContentChild(mContentChild, getStatusBarHeight(activity));
        if (mContentChild != null) {
            //fitsSystemWindow 为 false, 不预留系统栏位置.
            ViewCompat.setFitsSystemWindows(mContentChild, false);
        }
}

三、白色状态栏，修改状态栏颜色

白色状态栏

public static void setStatusBarLightMode(Activity activity, int color) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            //判断是否为小米或魅族手机，如果是则将状态栏文字改为黑色
            if (MIUISetStatusBarLightMode(activity, true) || FlymeSetStatusBarLightMode(activity, true)) {
                //设置状态栏为指定颜色
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {//5.0
                    activity.getWindow().setStatusBarColor(color);
                } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {//4.4
                    //调用修改状态栏颜色的方法
                    setStatusBarColor(activity, color);
                }
            } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                //如果是6.0以上将状态栏文字改为黑色，并设置状态栏颜色
                activity.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
                activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
                activity.getWindow().setStatusBarColor(color);

                //fitsSystemWindow 为 false, 不预留系统栏位置.
                ViewGroup mContentView = (ViewGroup) activity.getWindow().findViewById(Window.ID_ANDROID_CONTENT);
                View mChildView = mContentView.getChildAt(0);
                if (mChildView != null) {
                    ViewCompat.setFitsSystemWindows(mChildView, true);
                    ViewCompat.requestApplyInsets(mChildView);
                }
            }
        }
    }

调用

setStatusBarLightMode(this, Color.WHITE);
