我有一个全屏活动,它使用以下两个功能隐藏/显示系统 UI:
// This snippet hides the system bars.
public static void hideSystemUI(View view) {
// Set the IMMERSIVE flag.
// Set the content to appear under the system bars so that the content
// doesn't resize when the system bars hide and show.
view.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE);
}
// This snippet shows the system bars. It does this by removing all the flags
// except for the ones that make the content appear under the system bars.
public static void showSystemUI(View view) {
view.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
由于当我显示 Snackbar 并显示系统 UI 时 UI 以全屏模式布局,因此它被绘制在导航栏的后面。我没有使用 aCoordinatorLayout
并且目前没有理由使用它。鉴于系统 UI 的当前状态,让 Snackbar 显示在正确位置的正确方法是什么?
