             String result1[]=result.split("\\}\\,\\{");
             for(int i=0;i<=result1.length;i++)
             {

                     collegelist.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , result1));  
                     collegelist.setOnItemClickListener(new OnItemClickListener() {
                          public void onItemClick(AdapterView<?> parent, View view,
                              int position, long id) {
                            Intent intent = new Intent(ListCollege.this,viewCollege.class);
                            intent.putExtra("search_college", ((TextView) view).getText());

             httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
             HttpResponse response = httpclient.execute(httppost);
             HttpEntity entity = response.getEntity();
             is = entity.getContent();

             }
             is.close();
             result=sb.toString();
             **collegeAddress.setText(result);//Display Mysql Result in JSON**
             //String result1[]=result.split("\\}\\,\\{");
             //for(int i=0;i<result1.length;i++)
             //{
              //     result1[i]= result1[i].replace("[{", "").replace("institue_name", "").replace("\"", "").replace("}]", "").replace(":", "");

     }catch(Exception e){
             Log.e("log_tag", "Error converting result "+e.toString());
     }

}

Answer 1

Look at this part of yout code:

     for(int i=0;i<=result1.length;i++)
     {
             result1[i]= result1[i].replace("[{", "").replace("institue_name", "").replace("\"", "").replace("}]", "").replace(":", "");
             collegelist.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , result1));  
             collegelist.setOnItemClickListener(new OnItemClickListener() {
                  public void onItemClick(AdapterView<?> parent, View view,
                      int position, long id) {
                    Intent intent = new Intent(ListCollege.this,viewCollege.class);
                    intent.putExtra("search_college", ((TextView) view).getText());
                    startActivity(intent);
                 }
                });
     } 

You are Overriding the adapter and itemclicklistener of all items while looping

collegelist.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , result1));
collegelist.setOnItemClickListener(new OnItemClickListener()...

First what you need to do is save the result in result1 parsing it. After the loop Override the adapter , you must program the onclicklistener , using the arrayData to know which item is (with the position) are you clicking in .

Maybe it can be easy for you to have an auxiliar array to do it.
