安卓 透明 沉浸式 状态栏

项目中某个Activity和fragment 全透明，沉浸式状态栏

全透明效果：

1.直接在MainActivity中setContentView(R.layout.activity_main)之前加上以下代码

        getWindow().requestFeature(Window.FEATURE_NO_TITLE);

        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

            Window window = getWindow();

            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS

                    | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);

            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

                  //为避免底部导航栏覆盖注释掉这一行

//                 | 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);

        }
