问题描述
我在一个 React Native 项目中,如果用户向下拖动,则需要阻止 android 应用程序的状态栏。有没有办法做到这一点?
我唯一能做的就是隐藏它,但用户仍然可以打开它。
MainActivity.java:
package <PACKAGE>;
import android.os.Bundle;
import android.view.View;
import com.facebook.react.ReactActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;
import expo.modules.splashscreen.singletons.SplashScreen;
import expo.modules.splashscreen.SplashScreenImageResizeMode;
public class MainActivity extends ReactActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(null);
hideNavigationBar();
// SplashScreen.show(...) has to be called after super.onCreate(...)
// Below line is handled by '@expo/configure-splash-screen' command and it's discouraged to modify it manually
SplashScreen.show(this,SplashScreenImageResizeMode.CONTAIN,ReactRootView.class,false);
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
hideNavigationBar();
}
}
private void hideNavigationBar() {
getwindow().getDecorView().setsystemUIVisibility(View.SYstem_UI_FLAG_HIDE_NAVIGATION | View.SYstem_UI_FLAG_IMMERSIVE_STICKY);
}
/**
* Returns the name of the main component registered from JavaScript.
* This is used to schedule rendering of the component.
*/
@Override
protected String getMainComponentName() {
return "main";
}
@Override
protected ReactActivityDelegate createReactActivityDelegate() {
return new ReactActivityDelegate(this,getMainComponentName()) {
@Override
protected ReactRootView createRootView() {
return new RNGestureHandlerEnabledRootView(MainActivity.this);
}
};
}
}
