Is there a restriction to only use this if set minSdk to XX, becaus there were no xxhdpi? 回答1: Here are a couple drawbacks I can think of: More CPU intensive to resize the images, the app will use more battery and might feel more sluggish, especially on older devices.

问题 I have 5 images, I need to display this horizontally spaced one after the other. Instead of using 5 different images to display these 5 images in a LinearLayout with horizontal orientation, I would like to use a single image view. With LayerDrawable can I achieve this? If yes how?

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.

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?
