Bitmap bg = Bitmap.createBitmap(720, 1280,

//Setting the Bitmap as background for the ImageView
ImageView i = (ImageView) findViewById(R.id.ImageView);
i.setBackgroundDrawable(new BitmapDrawable(bg));
//Creating the Canvas Object
Canvas canvas = new Canvas(bg);
//Creating the Paint Object and set its color & TextSize
Paint paint = new Paint();
paint.setColor(Color.BLACK);
paint.setTextSize(50);
//To draw a Rectangle
canvas.drawText("Rectangle", 420, 150, paint);
canvas.drawRect(400, 200, 650, 700, paint);
//To draw a Circle
canvas.drawText("Circle", 120, 150, paint);
canvas.drawCircle(200, 350, 150, paint);
//To draw a Square
canvas.drawText("Square", 120, 800, paint);
canvas.drawRect(50, 850, 350, 1150, paint);
//To draw a Line
canvas.drawText("Line", 480, 800, paint);
canvas.drawLine(520, 850, 520, 1150, paint);
}
}
Thus a Simple Android Application to create and design an android application that draws basic graphical primitives on the screen using Android Studio is developed and executed successfully.
