问题 I tried the accepted solution posted here, but it appears to ignore padding. When the second view (in this case a button) displays, it's much smaller than the original which has padding. Is there a workaround for that? Thanks 回答1: Yes, TransitionDrawable extends from LayerDrawable which ignores the padding. This is the getPadding() method in the base Android code, which gets rid of anything you specified: @Override public boolean getPadding(Rect padding) { // Arbitrarily get the padding from

问题 This is my first SO question so please don't eat me alive... Here's my problem: I've imported few icons via Android Studio 1.4's new option - New/Vector Asset . As you know it lets you easily import and use vector drawables and creates pngs for compatibility with APIs <21. It puts the pngs in folders app/build/generated/res/pngs/debug/drawable-<density> (mdpi, ldpi, hdpi etc). It also generates the -v21 versions of all the folders and puts the vector drawable .xmls there. The problem started,

问题 Is it possible to have an xml drawable with parameters? Suppose I have an xml drawable that I want to reuse for the rounded corners, gradients etc, and the only variable is a color or two. Is it possible to specify/pass parameters to an xml drawable? 回答1: Perhaps you can derive your own class from Drawable, have a constructor accepting the parameters you want to make adjustable and in the constructor first call createFromXML passing your xml and then setup those adjustable parameters. I didn

问题 Last two questions stayed unanswered, I hope "third one's the charm" works :) I want application that is HDPI use those drawables in folder "drawable-xhdpi" and LDPI devices those in "drawable-mdpi". So I don't have to duplicate same images. Is this possible? 回答1: Yes, Android scales drawables, selecting the drawable that will produce the best result.
