将运行时生成的NinePatch保存在外部存储器上 [英] Saving run-time generated NinePatch on external memory

问题描述

我正在关注这篇文章以创建九个可绘制的补丁在运行时.我需要将9patch图像保存在内部/外部存储器上，以便我可以轻松地检索它的URI并将其分配给例如ImageView.有人知道我该怎么做到吗?

I'm following this post to create nine patch drawable at run-time. I need to save the 9patch image on the internal/external memory, so that i can easily retrieve it's URI and assign it to an ImageView for example. Does anybody know how can I achieve this?

P.S. Bitmap.compress方法不起作用，因为它将图像保存为常规(不是9patch)png文件.

P.S. Bitmap.compress method won't work, because it will save the image as a regular (not 9patch) png file.

P.S.我知道我可以序列化生成的NinePatch对象并将其保存到文件中.但是这种方式不能将其分配给RemoteViews对象(使用RemoteViews.setImageViewUri方法).因此，我需要将其保存为真实的九个补丁映像.

P.S. I know that I can serialize generated NinePatch object and save it to a file. But this way I can't assign it to a RemoteViews object (using RemoteViews.setImageViewUri method). So I need to save it as a real nine patch image.

推荐答案

您可以将图像存储为位图，然后使用

You can store the image as Bitmap and then create a NinePatch using http://developer.android.com/reference/android/graphics/NinePatch.html#NinePatch(android.graphics.Bitmap, byte[])
