我有我的应用程序，它与不同比例显示图像，调整内部（centerInside）ImageView的。我需要的是从ImageView的，包括背景（黑色在这种情况下）创建位图。

I have my application that is displaying images with different ratio, resized inside (centerInside) imageView. What I need is to create bitmap from the ImageView including the background (black in this case).

例如，我有设备屏幕小320x480，全屏幕的ImageView与图像调整到小280x480。我怎么能得到它小320x480位图？

So for example I have device screen 320x480, full screen imageView with image resized to 280x480. How could I get 320x480 bitmap from it?

在这个ImageView的我有一些标志或按钮，我不希望包括位图的顶部，他们就像在顶层。所有我需要的是位图与一些侧面图像和黑色边框。

On top of this imageview I have some logos or buttons that I don't want to include to bitmap, they're like on top layer. All I need is bitmap with image and black border from some sides.

推荐答案

您可以只使用的ImageView图像缓存。它将使整个视图，因为它奠定了（缩放，边框与背景等），以一个新的位图。

You could just use the imageView's image cache. It will render the entire view as it is layed out (scaled,bordered with a background etc) to a new bitmap.

只要确保它内置了。

imageView.buildDrawingCache();
Bitmap bmap = imageView.getDrawingCache();

有你的位图作为屏幕看到它。

there's your bitmap as the screen saw it.
