如何在Android中按字母顺序对字符串数组进行排序？

Question

I know there are many solutions to this question, but I am still facing a error. I have a string array, and the data to the array is inserted through webservice . Below is my code.

protected void onPostExecute(String result) {
            dialog.dismiss();
            int dip = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
                    (float) 1, getResources().getDisplayMetrics());

            JSONArray jarray;

            try {
                jarray= new JSONArray(result);
                    name= new String[jarray.length()];
for (int i=0;i<jarray.length();i++){

                    JSONObject jobj = jarray.getJSONObject(i);
                name[i]=    jobj.getString("Name");
}

Now in name[i] I get the names ,but those are not arranged alphabetically. I tried Arrays.sort(name); but it is giving me null pointer.

For alphabetic comparation you can use method compareTo(String) . sorting mechnism you will have to develop yourself or use ArrayList an Collections.sort() method.
