Randomly place objects in an activity

So I'm new to java, and I have the basics of object placement down. I'm trying to design an app in which 5 objects are randomly placed in a certain activity. How would I go about randomly placing these objects?

Thanks!

you can programmatically add your buttons to your activity with random position without using xml layout and here an example set buttons in activity 

 LinearLayout ll = new LinearLayout(this);
 ll.setOrientation(LinearLayout.VERTICAL);

 LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
 LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
 Button okButton=new Button(this);
 okButton.setText("some text");
 Random r  = new Random();
 okButton.setPadding(r.nextInt(), r.nextInt(), r.nextInt(), r.nextInt())
 ll.addView(okButton, layoutParams);

and here good thread to look at

Create a custom view that overrides the onDraw method.

Use Math.random or some other random number generating scheme to determine the x and y values of the bitmaps you are going to draw.

Then use Canvas.drawBitmap
