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

Answer 1

Tried and tested the following:

    mWebView = new WebView(this);
    mWebView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {

        @Override
        public void onLayoutChange(View view, int l, int t, int r, int b, int ol, int ot, int or, int ob) {
            Log.i("demo", String.format("%s: top=%d, bottom=%d, content height=%d",
                    Thread.currentThread().getStackTrace()[2].getMethodName(), t, b, mWebView.getContentHeight()
            ));
        }

    });

Logs:

12-20 16:08:33.969 1466-1466/yourPkg I/demo: onLayoutChange: top=0, bottom=0, content height=0
12-20 16:08:33.970 1466-1466/yourPkg I/demo: onLayoutChange: top=0, bottom=0, content height=0
12-20 16:08:34.061 1466-1466/yourPkg I/demo: onLayoutChange: top=0, bottom=1510, content height=0
12-20 16:08:34.091 1466-1466/yourPkg I/demo: onLayoutChange: top=0, bottom=1510, content height=2050

The last one is correct.
ViewTreeObserver sometimes gave me the wrong height.
