Android get height of webview content once rendered

Question

I\'m trying to get the height of a webview once it has been rendered. It always returns null, I\'ve tried getHeight, getMeasuredHeight, getCo

You can use ViewTreeObserver on that WebView to get actual height after rendering its content.

here's the sample code.

ViewTreeObserver viewTreeObserver  = mWebView.getViewTreeObserver();

viewTreeObserver.addOnPreDrawListener(new OnPreDrawListener() {
                   @Override
                   public boolean onPreDraw() {                                
                           int height = mWebView.getMeasuredHeight();
                           if( height != 0 ){
                                   Toast.makeText(getActivity(), "height:"+height,Toast.LENGTH_SHORT).show();
                                   mWebView.getViewTreeObserver().removeOnPreDrawListener(this);
                           }
                           return false;
                   }
           });
