将画布另存为文件，并放入滚动视图作为搜索结果

Question

In short I would like to know how to do this:

Saving a canvas with all the output of label/edittext/views as an (image)file on sdcard.

Using a search function, it will catch this canvas and display it on a scrollview or listview.

I hope someone out there knows the answer or having a nice example of the code.

Thanks for now, JackD

Answer 1

The following code saves the canvas bitmap to a file:

Dim Out As OutputStream
Out = File.OpenOutput(File.DirRootExternal, "Test.png", False)
Canvas1.Bitmap.WriteToStream(out, 100, "PNG")
Out.Close

You can draw the views to the canvas by using Canvas.DrawDrawable with the views background.

Not sure what you mean with the search function. You can later load this bitmap and display it on a ScrollView (with an ImageView) or ListView (with AddTwoLinesAndBitmap).
