问题 I have a custom class that extends ImageView that I'm programatically putting on to a RelativeLayout. I want each one of these images to be a specific width and height.

问题 I have an ImageView which is already resized to be a circle, and it contains an image inside, which is already fitted to fill the circle. The only problem is when I open the image in another part of my app it is not a circle but rather in its original form. This is because I didn't resize the image, but rather the ImageView.

问题 I'd like to be able to drag one imageview onto another, such that when they overlap, the overlapping area changes colour. To help visualise the problem, these imageviews are circular: when they overlap, it should form a Venn diagram-style image as shown below. I know you can detect whether the intersection has occurred by using: if (self.imageview1.bounds.contains(self.imageview2.bounds)) { ... } But do not really know how to colour the area in between! 回答1: so I figured out a way to do this
