in what format and value do u recieve color from server, is it in RGB format ? — Ak9637, Oct 28 '16 at 07:09
no, it's string format and sorry i didn't mention about json i got like that from server {"customerusername":"444erd43","customerid":"788","customername":"SATISH KKR","enrolldate":"2015-09-14","package":"Small","color":"green"} — M_sahoo26, Oct 28 '16 at 07:17
you shoud use RGB value to set color , instead of the string ; or you need to have a method , converting the string to its corresponding RGB value,or you can even use strings.xml to save the values of the color u expect to get from server and according to your string value you should get the color values which you need to have saved in your colors values xml value , and then set your background — Ak9637, Oct 28 '16 at 07:19
Currently, I guess you are using static color from Color.xml file and setting it like this ll.setBackgroundColor(color); Is this working? When you send it through PHP, you can set it using, ll.setBackgroundColor(Color.parseColor(BackgroundColorInHashCode())); — Myth, Oct 28 '16 at 07:26
@M_sahoo26 , i have posted an example as your answer below , hope it helps you understand — Ak9637, Oct 28 '16 at 07:27
or you can use reflection to get a list of all colors, defined in java.awt.Color (http://stackoverflow.com/a/8125171/6635287) and then serach in list for the current color — Radinator, Oct 28 '16 at 07:28

For example : If you receive color=green;

You can get

getResources.getString(R.string."your color value here");

and you should have a string resources in strings.xml like

<string name="your color name">@color/colorGreen</string>

and the values of this color be defined in ur colors.xml like

<color name="colorGreen">#DF201A</color>

Pass your list in constructor of BaseAdapter, then call notifydataseChanged

    class AdapterList extends BaseAdapter {

    ArrayList<StatusList> statusList;

    public BaseAdapter(ArrayList<StatusList> statusList) {
    this.statusList = statusList;
    }

}
