            new int[] {
                     R.id.l2, R.id.l3, R.id.l4, R.id.l5, R.id.l6, R.id.l7}){
         @Override
         public View getView(int position, View convertView, ViewGroup parent) {
             View v = convertView;
             if (v == null) {
                 LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                 v = vi.inflate(R.layout.list_item, null);
             }
              text1 = (TextView) v.findViewById(R.id.l7);

              String rgbColor=  dataList.get(position).get(TAG_COLOR);
              String[] ARGB = rgbColor.split(" ");     
              a=Integer.parseInt(ARGB[0]);
              r=Integer.parseInt(ARGB[1]);
              g=Integer.parseInt(ARGB[2]);
              b=Integer.parseInt(ARGB[3]);                        
              text1.setBackgroundColor(Color.rgb(r, g, b));
              return super.getView(position, v, parent);
          }

     };

Problem

I am trying to set text background color using `text1.setBackgroundColor(Color.rgb(r,g,b));` were red,green,blue values are coming from database based on value `i` set `r=128,g=255,b=128` programmatically it color was dull green but i run the program it will displayed red color ``` for(int i = 0; i < list.length(); i++){ JSONObject c = list.getJSONObject(i); // Storing each json item in variable // String GRPCODE = c.getString(TAG_GRPCODE); String GRPNAME = c.getString(TAG_GRPNAME); String QTY = c.getString(TAG_QNT); String BUDGET = c.getString(TAG_BUDGET); String STOCK = c.getString(TAG_STOCK); String DIFF = c.getString(TAG_DIFF); String DIFF_P = c.getString(TAG_DIFF_P); COLOR = c.getString(TAG_COLOR); /*String[] ARGB = COLOR.split(" "); String V1=ARGB[0]; String V2=ARGB[1]; String V3=ARGB[2]; String V4=ARGB[3]; a=Integer.parseInt(V1); r=Integer.parseInt(V2); g=Integer.parseInt(V3); b=Integer.parseInt(V4);*/ HashMap<String, String> map = new HashMap<String, String>(); // adding each child node to HashMap key => value // map.put(TAG_GRPCODE, GRPCODE); map.put(TAG_GRPNAME, GRPNAME); map.put(TAG_QNT, QTY); map.put(TAG_BUDGET, BUDGET); map.put(TAG_STOCK, STOCK); map.put(TAG_DIFF, DIFF); map.put(TAG_DIFF_P, DIFF_P); map.put(TAG_COLOR,COLOR); //map.put(TAG_PHONE_MOBILE, mobile); // adding HashList to ArrayList contactList.add(map); } } catch (JSONException e) { e.printStackTrace(); } /** * Updating parsed JSON data into ListView * */ ListAdapter adapter = new SimpleAdapter(this, datatList, R.layout.list_item, new String[] { TAG_GRPNAME, TAG_QNT, TAG_BUDGET, TAG_STOCK, TAG_DIFF, TAG_DIFF_P, }, new int[] { R.id.l2, R.id.l3, R.id.l4, R.id.l5, R.id.l6, R.id.l7}){ @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.list_item, null); } text1 = (TextView) v.findViewById(R.id.l7); HashMap<String, String> map=dataList.get(position); map.get(TAG_COLOR); String[] ARGB = COLOR.split(" "); String V1=ARGB[0]; String V2=ARGB[1]; String V3=ARGB[2]; String V4=ARGB[3]; a=Integer.parseInt(V1); r=Integer.parseInt(V2); g=Integer.parseInt(V3); b=Integer.parseInt(V4); text1.setBackgroundColor(Color.rgb(r,g,b)); return super.getView(position, v, parent); } }; ```
