@UmaYalanati and @caman9119

I have the same issue for setting the image below the text and i tried to apply ur given solution that is

URLImageParser.this.container.invalidate(); //redraw the image by invalidating the container
container.setText(container.getText());

but the last line of setting text gives error as this method is not present for that container. Looking for reply ASAP....

@parthvora25

if(container instanceof TextView) { ((TextView)container).setText(((TextView)container).getText()); }

thx @Antarix! I've tried it. it works.
