This question isn't that clear but if you have a Bitmap and want draw it in an ImageView you just call ImageView.setImageBitmap().

@Override protected void onDraw(Canvas canvas) { canvas.drawColor(0xFFAAAAAA); canvas.drawBitmap(mBitmap, 0, 0, mBitmapPaint); if(item_id==3){ canvas.drawText(AppModel.contents, 100, 100, mPaint); } else{ canvas.drawPath(mPath, mPaint); } } – saranya krishnan Mar 05 '11 at 14:40

In this case, you can convert your custom view to Bitmap image by using the following snippet:

public static Bitmap getBitmapFromView(View view) {
        //Define a bitmap with the same size as the view
        Bitmap returnedBitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(),Bitmap.Config.ARGB_8888);
        //Bind a canvas to it
        Canvas canvas = new Canvas(returnedBitmap);
        //Get the view's background
        Drawable bgDrawable =view.getBackground();
        if (bgDrawable!=null) 
            //has background drawable, then draw it on the canvas
            bgDrawable.draw(canvas);
        else 
            //does not have background drawable, then draw white background on the canvas
            canvas.drawColor(Color.WHITE);
        // draw the view on the canvas
        view.draw(canvas);
        //return the bitmap
        return returnedBitmap;
}

Then you can add bitmap to image view by using the following method:

imageview.setBitmapImage(returnedBitmap);
