问题 How I can detect a touch event from down to up (or the inverse) in Android widget (sdk 2.3.3)? 回答1: Try setting an OnTouchListener to the widget and getting the event codes with event.getAction(); Suppose your widget is an ImageView.

It is also very hard to understand the crux of what I think should be such a simple thing. Can someone on here please clarify for me. It would seem that you just set a different drawable as the

问题 How do i use intent in android widget to open images in browser. 回答1: If the image is on the internet it would be as simple as this: String url = "http://www.picturesnew.com/media/images/image-background.jpg"; Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(url)); startActivity(i); However if the image is inside of your assets you can't open it in the browser.
