Is there a way to hide and show the zoom controls on a WebView?

Question

I have a two Views. One is a WebView and the other is an ImageView. I set the auto zoom controls for the WebView like so:

webview.getSettings().setBuiltInZoomControls(true);

I am just changing the visibility of both Views using GONE and Visible. While changing my View from WebView to ImageView, the zoom controls do not lose their visibility for some period of time.

Is there any possible way to hide and show the Autozoomcontrols?

Edit:

I tried these methods, but it's still not working.

webview.getZoomControls().setVisibility(View.GONE);
webview.getZoomControls().invalidate();

Answer 1

public void setZoomControlGone(View view){
    Class<?> classType;
    Field field;
    try {
        classType = WebView.class;
        field = classType.getDeclaredField("mZoomButtonsController");
        field.setAccessible(true);
        ZoomButtonsController mZoomButtonsController = new ZoomButtonsController(view);
        mZoomButtonsController.getZoomControls().setVisibility(View.GONE);
        try {
            field.set(view, mZoomButtonsController);
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        }
    } catch (SecurityException e) {
        e.printStackTrace();
    } catch (NoSuchFieldException e) {
        e.printStackTrace();
    }
}
