imageview

问题 I am making a number of imageViews programmatically in a loop and assigning them ids. But when in onClick method I need to get the id of images, it is returning the id of the last image only. How do I get the id of the image that is clicked? The code I am using: for (int j = 0; j < 5; j++) { TableRow tr = new TableRow(this); imageUrl = "http://ondamove.it/English/images/users/"; imageUrl = imageUrl + listObject.get(j).getImage(); image = new ImageView(this); image.setPadding(20, 10, 0, 0);

问题 I have 2 ImageViews which have AnimationDrawable backgrounds to animate a box opening and closing when you click on it. The 2 images are slightly overlapping (the transparent area) so they can be closer together. The problem this is causing is that I am unable to click on regions of the 1st image where the 2nd image (transparent area) is overlapping. Is there a way to set a clickable region of an ImageView? 回答1: I don't think that you can "define a clickable region on an ImageView" like you
