2.Set Text in View(for ex,button,textview,edittext etc)-> i m doing settext() of view.but can't getting x,y co-ordinate array of whole displaying text.

I am draw this string using below code:

public class DrawCanvas extends View {
        public DrawCanvas (Context mContext) {
            super(mContext);
        }

        public void onDraw(Canvas canvas) {
            clipBounds_canvas = canvas.getClipBounds();
            String str = "णमो अरिहंताणं";
            paint.setColor(Color.WHITE);
            paint.setStyle(Paint.Style.FILL);
            canvas.drawPaint(paint);
            paint.setTextAlign(Paint.Align.CENTER);
            paint.setColor(Color.BLACK);
            int scaledSize = (int) getResources().getDimensionPixelSize(R.dimen.myFontSize);
            int fontSize = scaledSize;
            paint.setTextSize(fontSize);
            Log.e("tag", "canvas.getWidth()" + canvas.getWidth());
            int xPos = (canvas.getWidth() / 2);
            int yPos = (int) ((canvas.getHeight() / 2));
            paint.setAntiAlias(true);
            canvas.drawText(str, xPos, yPos, paint);
            canvas.drawPath(drawPath, paint);
        }
