Android-从屏幕上提取像素颜色

Question

I can't seem to find a good answer for this anywhere.

Is it possible to extract the a single pixel rgb directly from an android screen? (Not by taking a screen dump)

I need direct access to what's on the screen.

Any thoughts?

Thanks.

Answer 1

If you are using custom views and canvases, you definitely can:

have a look: http://developer.android.com/reference/android/graphics/Bitmap.html#getPixel(int,int )

Answer 2

I don't know exactly but I can give you an approach. if the view's drawingCache enabled you can get bitmap from getDrawingCache and you can get pixel data from that.
