Remove system menu bar from react native android a

问题:

My problem is simple and I have been unable to find a solution. The menu bar is very annoying in my app and I am hoping that there is a way to remove it.

Looking at Hiding the Navigation Bar I found this:

You can hide the navigation bar on Android 4.0 and higher using the SYSTEM_UI_FLAG_HIDE_NAVIGATION flag. This snippet hides both the navigation bar and the status bar:

View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
          | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

I do not know if that's exactly what you was looking for, but you can test it.

I suggest you read more about native modules, it enables you to write native code and access it from JS.

Also the StatusBar module is very similar to what you want to do here, you can have a look at the source.
