How to make any view to draw to canvas?

Yeah, you can do this. Keep in mind, since you're not attaching it to a layout, you'll need to lay it out manually before drawing it:

view.layout(0, 0, viewWidth, viewHeight);

And unless you just know exactly what you want for those width and height parameters, you may also want to measure it first:

int widthSpec = MeasureSpec.makeMeasureSpec (ViewGroup.LayoutParams.WRAP_CONTENT, MeasureSpec.UNSPECIFIED;int heightSpec = MeasureSpec.makeMeasureSpec (400, MeasureSpec.UNSPECIFIED;view.measure(widthSpec, heightSpec);view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());

EDIT:

If you already know the width and height you need:

//Lay the view out with the known dimensionsview.layout (0, 0, rect.width(), rect.height());//Translate the canvas so the view is drawn at the proper coordinatescanvas.save();canvas.translate(rect.left, rect.top);//Draw the View and clear the translationview.draw(canvas);canvas.restore();

EDIT again:

Yes, tested. You can try this yourself:

public class DrawingActivity extends Activity {    public void onCreate (Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //Set a Rect for the 200 x 200 px center of a 400 x 400 px area        Rect rect = new Rect();        rect.set(100, 100, 300, 300);        //Allocate a new Bitmap at 400 x 400 px        Bitmap bitmap = Bitmap.createBitmap(400, 400, Bitmap.Config.ARGB_8888);        Canvas canvas = new Canvas(bitmap);        //Make a new view and lay it out at the desired Rect dimensions        TextView view = new TextView(this);        view.setText("This is a custom drawn textview");        view.setBackgroundColor(Color.RED);        view.setGravity(Gravity.CENTER);        //Measure the view at the exact dimensions (otherwise the text won't center correctly)        int widthSpec = View.MeasureSpec.makeMeasureSpec(rect.width(), View.MeasureSpec.EXACTLY);        int heightSpec = View.MeasureSpec.makeMeasureSpec(rect.height(), View.MeasureSpec.EXACTLY);        view.measure(widthSpec, heightSpec);        //Lay the view out at the rect width and height        view.layout(0, 0, rect.width(), rect.height());        //Translate the Canvas into position and draw it        canvas.save();        canvas.translate(rect.left, rect.top);        view.draw(canvas);        canvas.restore();        //To make sure it works, set the bitmap to an ImageView        ImageView imageView = new ImageView(this);        imageView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));        setContentView(imageView);        imageView.setScaleType(ImageView.ScaleType.CENTER);        imageView.setImageBitmap(bitmap);    }}
