android-image

问题 Ok...so here's the scenario.. Starting from scratch, I want to display THREE stars (i have an image that I want to use), centered. I want to post a different word in each star. Of course, I do not want it hard-coded, but once I can get the layout right, the rest will be easy. Can anyone help please? I would be greatly appreciated. 回答1: If you're wanting to just overlay text on top of an image, just wrap the ImageView in a FrameLayout, and then just define a TextView after the ImageView. It

问题 I'm new to android programming and every single somewhat-similar question is from three or so years ago and doesn't really answer my question. Android Studio used to have different drawable folders for different dpi. Now there is only one. So if I have two images with the same name but for different dpi, where do I add them so that during runtime the phone can use the appropriate image? Also, most android phones now are xhdpi or xxhdpi--do I really need to include any images less than that?

Assume I only have a single layout, so what I need is to prepare the images and place them under the corresponding drawable folders, right? Thanks 回答1: Yes, those are the correct sizes. Yes, just put your various versions in the res/drawable-ldpi,
