我想在屏幕上的特定区域创建位图。例如下图中我怎么能捕捉到下面的窗面积，并将其转换成位图？

I'm trying to create a bitmap from a specific area on the screen. For example in the following image how could I capture the windowed area below and convert it into a bitmap?

我知道你可以使用setDrawingCacheEnabled（真），但捕捉全景，当所有我想要的是在视图中的区域。

I know you can use setDrawingCacheEnabled(true), but that captures the whole view, when all I want is an area within the view.

推荐答案

您可以实际使用Android的 Bitma pregionDe coder.de codeRegion（）创建后的InputStream 从位图。

You can actually use Android's BitmapRegionDecoder.decodeRegion() after you create an InputStream from your Bitmap.

您可以通过一个矩形对象的德codeRegion像这样方法：

You can pass a Rect object to the decodeRegion method like so:

BitmapRegionDecoder brd = BitmapRegionDecoder.newInstance(inputStream, true);
Bitmap croppedBitmap = brd.decodeRegion(new Rect(left, top, right, bottom), null);
