android - How can I get the bitmap of the canvas I get in onDraw?

Question

How can I create the bitmap from the canvas of custom view.

Answer 1

While there is no getBitmap() function for a canvas, since you are making a custom view, what you can do instead is write a function like this inside your view class.

public Bitmap get(){
   return this.getDrawingCache();
}

This returns the Bitmap of the view, but it is important that in all your constructors you add this,

this.setDrawingCacheEnabled(true);

Otherwise getDrawingCache will return null
