隐藏受信任的 Web 活动中的状态栏

Question

在关注谷歌开发者关于twa的页面并隐藏网址栏之后，我现在有一个没有url栏的工作twa。但状态栏仍然可见。

是否可以在twa中隐藏状态栏以获得全屏视图？

试试这个来隐藏你的状态栏

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/secondaryTextColor</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:windowTranslucentNavigation">true</item>
</style>

完全希望它能为你工作。

更新好的，现在试试这个。它将启用全屏模式，因此它将适合您的要求，即隐藏状态栏。

    @Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        hideSystemUI();
    }
}
private void hideSystemUI() {
    // Enables regular immersive mode.
    // For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE.
    // Or for "sticky immersive," replace it with SYSTEM_UI_FLAG_IMMERSIVE_STICKY
    View decorView = getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE
            // Set the content to appear under the system bars so that the
            // content doesn't resize when the system bars hide and show.
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            // Hide the nav bar and status bar
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN);
}
// Shows the system bars by removing all the flags
// except for the ones that make the content appear under the system bars.
private void showSystemUI() {
    View decorView = getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
