Answer 1

For a draw line between your two views.

Create class for view which draw a line.

public class DrawView extends View {
    Paint paint = new Paint();

    public DrawView(Context context) {
        super(context);
        paint.setColor(Color.BLACK);
    }

    @Override
    public void onDraw(Canvas canvas) {
            canvas.drawLine(0, 50, 350, 50, paint);
    }

}

now from your activtiy where you want to add this line in your layout. Create object of this class and add this view in your layout.

According to your requirment try like this.

DrawView drawView; drawView = new DrawView(this);

frame1.addView(ball1);
                            // add that view here
frame1.addView(drawView);
frame1.addView(ball2);
                            // same way here
frame1.addView(ball3);
