android-drawable

问题 I'm developing a basic paint application in android and I can't seem to programmatically set custom drawables for my radio buttons. These radio buttons consist of a LayerDrawable with a white ColorDrawable for the borders and an inset yellow (or whatever color it is) ColorDrawable for the center.

问题 We have a Cordova-App which contains a file 'icon.png' in every drawable-xy folder. We provide push notifications using OneSignal. The notifications are working as expected. Except the small icon. There is only a blank icon on the top bar of my phone, where app-symbols are displayed. I tried using the following snippet: { ... "small_icon" : "@android:drawable/icon.png" .... } I also tried lots and lots of other variations without "android", without "drawable", without slash, with .png and

问题 I'm attempting to colorize a graphic using setColorFilter . The following code seems to work fine on lollipop, but it seems to have no effect on kitkat, the icon is rendered in it's original colors: Drawable icon = ContextCompat.getDrawable(context, R.drawable.ic_chat_button).mutate(); icon.setColorFilter(context.getResources().getColor(R.color.control_tint_color), PorterDuff.Mode.SRC_ATOP); icon.invalidateSelf(); The mutate and invalidateSelf calls don't seem to have any effect on the

问题 Background Google Calendar app has an action item that dynamically change according to the current day ("today"): I'm required to do a very similar thing, but with a slightly different image that surrounds the text. The problem I did succeed to make it work, by creating a Drawable that has text and image in it (based on here). However, I'm don't think I did it well enough : Text font might be different across devices, so might not fit well in what I wrote. Not sure if it's because of the

问题 I've used a couple of images which I've imported using Android Studio's Vector Asset Studio through a local SVG file. The images loaded perfectly on my nexus 6p, however, on the Sony Xperia Z, its very pixelated, and on Samsung Galaxy s2, its even worse. From my understanding, since the file is a xml (vector) and not a png file, it should have been able to resize automatically or am I missing out on something. I've attached an image of the 3 cases. EDIT: Just some extra info: The file was
