How to Draw TextView on Canvas in android..?

Question

We have Canvas.DrawBitmap(), Canvas.drawText(). Do we have any Method in Canvas which takes TextView as a parameter or any other method to display TextView on Canvas?

Actually, I have a alphabet in TextView and I have to make drawing on that alphabet which is in canvas.

Please suggest anything....Thanks for your cooperation

You can't draw a Textview directly, but you can put it in a layout and draw the layout. Something like this:

LinearLayout layout = new LinearLayout(context);

TextView textView = new TextView(context); 
textView.setVisibility(View.VISIBLE);
textView.setText("Hello world");
layout.addView(textView);

layout.measure(canvas.getWidth(), canvas.getHeight());
layout.layout(0, 0, canvas.getWidth(), canvas.getHeight());

// To place the text view somewhere specific:
//canvas.translate(0, 0);

layout.draw(canvas);

about the measure() call, I had more success using MeasureSpec.makeMeasureSpec(canvas.getWidth(), MeasureSpec.EXACTLY) instead of canvas.getWidth() (and same for height). – Emmanuel Touzery Jun 12 '12 at 11:33
is it possible to make the TextView clickable? I am adding an onClickListener but it doesn't seem to be working. – silent_dev Feb 18 '18 at 19:45

Doesn't TextView have a draw method that takes a canvas? Is it a no-op? – Ian Warburton Apr 28 '18 at 17:21

May be you need to use StaticLayout. It can draw formatted text, manages word wrapping and so on. Have a look at http://developer.android.com/reference/android/text/StaticLayout.html

You need to create a class which will extend Textview. After that override onDraw method. This method provides you to draw your textview tha way you like it
