In this case you should consider an AbsoluteLayout, it would make more sense. Since this way you can randomly generate and x and an y position for each child.

There are a ton of examples on the net, here is the first one found by a Google search. The gist is something like this:

To plot something like this on the screen:

You can have an AbsoluteLayout declared like this in your activity xml file:

<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent">
   
<!--  Declare your shapes --> 

</AbsoluteLayout>

And then in your Activity or Fragment you will add your Shape objects at random positions, with something like:

public class MainActivity extends Activity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  // ...
  // Establish the working area
  DisplayMetrics displayMetrics = new DisplayMetrics();
  getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
  int widthArea = displayMetrics.widthPixels;
  int heightArea = displayMetrics.heightPixels;
  //Init the random generator
  Random r = new Random();
  // Then for each Shape  
  // ...
  AbsoluteLayout.LayoutParams pos = 
   (AbsoluteLayout.LayoutParams)shape.getLayoutParams();
  pos.x =  r.nextInt(widthArea);
  pos.y =  r.nextInt(heightArea);
  shape.setLayoutParams(pos);
  // ...
 }  
}
