如何显示多个检索MySQL和Android数据的项目

I am currently following a tutorial on retrieving data utilizing an online sql database, volley and android. How ever i am having real trouble making it so that more than one item is displayed. It only displays 1 row of the table even if 5 records match. Any help on this would be much appreciated

I added a loop to the php, which does work if i go through the url. exampleurl/id="1" displays all correct records in the browser. but im stuck on the java side as it only displays one item

while($res = mysqli_fetch_array($r)){

 $result = array();

You are using the same TextView to override again and again the data:

 textViewResult.setText("Name:\t"+name+"
Address:\t" +address+ "
Vice Chancellor:\t"+ vc);

Why don't you use a ListView to show all your results?

You should use Listview or spinner based on your requirement to show more than one item.

    JSONArray result = jsonObject.getJSONArray(Config.JSON_ARRAY);

after the the above code simply use

    JSONObject collegeData;      
    for(int i = 0; i<result.length(); i++){
         collegeData = result.getJSONObject(i);
         name = collegeData.getString(Config.KEY_NAME);
         address = collegeData.getString(Config.KEY_ADDRESS);
         vc = collegeData.getString(Config.KEY_VC);

         // populate logic here for your spinner or list

    } 

Edit

Initialize below

    ArrayAdapter adapter;
    private ArrayList<String> dataList = new ArrayList<>();

in onCreate() declare the adapter and your ListView

    ListView listView = (ListView) findViewById(R.id.your_list_view_id);
    adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_item, dataList);

Now replace "//populate logic here for your spinner or list" with

    dataList.add(name + " " + address + " " vc);

After for loop add these line

    listView.setAdapter(adapter);
    adapter.notifyDataSetChanged();

Do this and let me know the output. Of course I didn't check this code but it should do the work. Good luck.
