Android – issue: the specified child node already has a parent node. You must first call removeview() on the child’s parents

I develop applications to add dynamic data to multiple table views. The structure is as follows

My code in onpostexecute is:

    protected void onPostExecute(List<String> results){
int ind,i = 0;
ScrollView sv=null;
TableLayout tl=null;
TableRow tr = null;
int mjsonlength=results.size();
if(results!=null){

 TableLayout indextl=(TableLayout)findViewById(R.id.indextablelayout);
    TableRow indextr=new TableRow(SubProducts.this);
    //indext1.moveToFirst();
    LinearLayout llt=(LinearLayout)findViewById(R.id.alltablell);
    //for(int f=0;f<mjsonlength;f++){

        for( ind=0;ind<indextitle.size();ind++)
        {

            TextView indextv=new TextView(SubProducts.this);
            indextv.setBackgroundResource(R.drawable.greenbg);
            indextv.setHeight(25);
            indextv.setWidth(50);
            indextv.setId(6);
            indextv.setTextColor(Color.WHITE);
            indextv.setText(indextitle.get(ind));
            indextv.setPadding(20,10,6,3);
            indextr.addView(indextv);

            indextl.addView(indextr,6);

            sv=new ScrollView(SubProducts.this);
             tl=new TableLayout(SubProducts.this);
             for( i=0;i<mjsonlength;i++){
                    tr=new TableRow(SubProducts.this);

                    if(ind==i)  {

                        RelativeLayout rl=new RelativeLayout(SubProducts.this);
                        Resources res = getResources(); //resource handle
                          rl.setBackgroundResource(R.drawable.prd_@R_33_2419@);

                         RelativeLayout.LayoutParams newParams1 = new RelativeLayout.LayoutParams(
                                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                                    RelativeLayout.LayoutParams.WRAP_CONTENT);

                            image=new ImageView(SubProducts.this);
                            image.setLayoutParams(newParams1);
                            image.setId(1);
                            image.setImageBitmap(bmp);
                            image.setPadding(5, 20, 5, 5);
                            rl.addView(image,1);



                          RelativeLayout.LayoutParams lprams = new RelativeLayout.LayoutParams(
                                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                                    RelativeLayout.LayoutParams.WRAP_CONTENT);
                            lprams.addRule(RelativeLayout.RIGHT_OF, 1);

                          TextView tv1=new TextView(SubProducts.this);
                        Spanned marked_up = Html.fromHtml(description.get(i));
                        tv1.setText((marked_up.toString()).substring(1, 170).replaceAll("&nbsp;",""));
                        tv1.setLayoutParams(lprams);
                        tv1.setId(2);
                        tv1.setHeight(150);
                        tv1.setWidth(130);
                        tv1.setPadding(20, 10, 0, 10);
                        rl.addView(tv1,2);


                         RelativeLayout.LayoutParams newParams = new RelativeLayout.LayoutParams(
                                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                                    RelativeLayout.LayoutParams.WRAP_CONTENT);
                         newParams.addRule(RelativeLayout.BELOW, 2);
                        TextView tv=new TextView(SubProducts.this);
                        tv.setText(productname.get(i));
                        tv.setLayoutParams(newParams);
                        tv.setTextColor(Color.WHITE);
                        tv.setId(3);
                        tv.setPadding(10, 0, 0, 10);
                        rl.addView(tv,3);


                        tr.addView(rl);
                        tr.setPadding(5, 10, 5, 10);


                    }
                    tl.addView(tr);

            }

             sv.addView(tl);

                llt.addView(sv);

        }

    }

}

I got the following error:

The loop variable value should be the same for both loops. Inorder obtains the sub products of the corresponding products. I am struggling with the above errors. Anyone with ideas. Plz suggests an appropriate solution. Thank you in advance

Edit:

ArrayList<String> productname=new ArrayList<String>();
ArrayList<String> description=new ArrayList<String>();
ArrayList<String> indextitle=new ArrayList<String>();
 ArrayList<String> mStrings = new ArrayList<String>();

Under doinbackground:

 JSONObject json = array.getJSONObject(i);

     manJson = json.getJSONObject("product");
     mStrings.add(manJson.getString("productimage"));
     productname.add(manJson.getString("productname"));
    indextitle.add(manJson.getString("subcategoryid"));
    description.add(manJson.getString("description"));

resolvent:

OK, the second potential problem is: indextl. Addview (indextr);

Indextr will be added in each loop iteration, but it is the same view. You can only add a view to the hierarchy once. You may want a new instance for each loop iteration. I can't say for sure, but this may be the problem
