你应该做到以下几点:
科特林:
private fun hideSystemBars() {
val windowInsetsController =
ViewCompat.getWindowInsetsController(window.decorView) ?: return
// Configure the behavior of the hidden system bars
windowInsetsController.systemBarsBehavior =
WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
// Hide both the status bar and the navigation bar
windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())
}
Java:
private void hideSystemBars() {
WindowInsetsControllerCompat windowInsetsController =
ViewCompat.getWindowInsetsController(getWindow().getDecorView());
if (windowInsetsController == null) {
return;
}
// Configure the behavior of the hidden system bars
windowInsetsController.setSystemBarsBehavior(
WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
);
// Hide both the status bar and the navigation bar
windowInsetsController.hide(WindowInsetsCompat.Type.systemBars());
}

尝试使用style.xml中的appcompat。它为所有平台提供支持。
<!-- Application theme. -->
<style name="AppTheme.FullScreen" parent="AppTheme">
<item name="android:windowFullscreen">true</item>
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar" />
只需将此代码粘贴到onCreate()方法中
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
import androidx.core.view.WindowInsetsCompat.Type
fun Activity.fullscreen() {
with(WindowInsetsControllerCompat(window, window.decorView)) {
systemBarsBehavior = WindowInsetsControllerCompat.BEHAVIOR_SHOW_BARS_BY_SWIPE
hide(Type.systemBars())
}
}
fun Activity.exitFullscreen() {
WindowInsetsControllerCompat(window, window.decorView).show(Type.systemBars())
}
如果你使用AppCompat和ActionBarActivity,那么使用这个
getSupportActionBar () hide ();
