i'm confusing. thanks

try code

call method, passing in outer viewgroup want screen shot of:

public bitmap screenshot(view view) {     bitmap bitmap = bitmap.createbitmap(view.getwidth(),             150, config.argb_8888);     canvas canvas = new canvas(bitmap);     view.draw(canvas);     return bitmap; }
