[android help] Set Icons over Imageviews(inside frameLayout)

Set Icons over Imageviews(inside frameLayout)

I am new to android.I have a question that i am trying to put icons over the FrameLayout.

Now,all the four colored triangular Boxes are the ImageViews in the different four FrameLayouts and all the four Frame Layouts are inside a RelativeLayout.

Now I want to put the icons over the 4 FrameLayouts.I am making these layouts in jaa not in XML. So,I am not able to put these icons over the particular ImageView(framelayout); I am using this code to set the position of icons over the particular frame or imageview,

ImageView icon = new ImageView(getBaseContext());
        icon.setImageResource(R.drawable.wordpress_icon);        
        LayoutParams paramsIcon = new LayoutParams(50, 50);
        MarginLayoutParams IconPara = new MarginLayoutParams(50,50);
       // IconPara.setMargins(500, 500, 0, 0);
        //icon.setPadding(0, 0, width-60, height-60);
        icon.layout(50, 50, 0, 0);
        icon.requestLayout();
        icon.setLayoutParams(paramsIcon);

But after all , I am not able to put these icons over the specific place on the screen.
