            contentHolder = (LinearLayout)rootview.findViewById(R.id.contentOuter);
        //add LayoutParams
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        //params.setMargins(10, 20, 10, 20); // llp.setMargins(left, top, right, bottom);
        contentHolder.setOrientation(LinearLayout.VERTICAL);

        ftv = new FlowTextView(getActivity());

        FlowTextView.LayoutParams fp = new FlowTextView.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
        fp.setMargins(0, 10, 0, 10); 
        ftv.setLayoutParams(params);
        ftv.setId(110);
        ftv.setText("Currently it is placing that image as the background to the view and not the actual image in it.Currently it is placing that image as the background to the view and not the actual image in it.Currently it is placing that image as the background to the view and not the actual image in it..");

        ImageView im = new ImageView(getActivity());
        im.setBackgroundResource(R.drawable.av1);
        im.setId(5);

        RelativeLayout rt = new RelativeLayout(getActivity());
        RelativeLayout.LayoutParams rparams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        rparams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
        rparams.setMargins(0, 10, 0, 10);
        rt.setLayoutParams(rparams);
        rt.addView(im);

        ftv.addView(rt);
        ftv.invalidate();


        //add the textView and the Button to LinearLayout
        contentHolder.addView(ftv);
