问题 Whenever I try to add a 9-patch image to the \drawable folder in my project, I get the same error: ERROR: 9-patch image C:\...\res\drawable\appwidget.9.png malformed. Frame pixels must be either solid or transparent (not intermediate alphas). Found at pixel #3 along top edge.

I have a screen where the user has many items to input so screen space is at a premium. I want the look of the widget on the screen (before the user presses it) to be similar to an EditText or the left portion of the Spinner widget (without the normal down triangle) on the right side of the Spinner. Then when the user presses the widget, he/she will get the normal Spinner selection dialog. Is there some Spinner style attribute I can change to accomplish this? I have not been able to see code like this. Thanks lencinhaus One thing you can do is take Spinner 's source code from android code base

Create a NinePatch/NinePatchDrawable in runtime

由 天大地大妈咪最大 提交于 2019-11-26 11:42:42
I have a requirement on my Android application that parts on the graphics should be customizable, by retrieving new colors and images from the server side. Some of these images are nine-patch images.

The NinePatch can NOT be loaded from the Resources, since the images doesn't exist in
