            {
                x_up = (int) arg1.getX();
                y_up = (int) arg1.getY();

            Log.v("log", "x pos is "+x_up +"y pos is "+y_up);


            if((x_down-x_up)>30)
            {
                wv.loadData("<img src=\"myurl_1\">", "text/html", null);
            }
            else if((x_up-x_down)>30)
            {
                 wv.loadData("<img src=\"myurl_2\">", "text/html", null);
            }

            }
            return true;
        }
    });

Thanks in advance...

Answer 1

You are returning always true from the onTouch method, which means that you are the only one responsible for handling touch events..
you should return true only in the cases you want, and return super.onTouch in the other cases..

Answer 2

       webView.getSettings().setBuiltInZoomControls(true);

add this code to your webview i hope it works
