Answer 1

dies mit Volley-Bibliothek So versuchen tun:

private void sendjsonRequest(){ 

     JsonArrayRequest jsonArrayRequest=new JsonArrayRequest(Request.Method.GET,"serverlink",null, new Response.Listener<JSONArray>() { 

      @Override 
      public void onResponse(JSONArray response) { 

       String[] banks=parsejsonResponse(response); 
       Spinner s = (Spinner) findViewById(R.id.Spinner01); 
       ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
       android.R.layout.simple_spinner_item, banks); 
       s.setAdapter(adapter); 


      } 

     }, new Response.ErrorListener() { 

      @Override 
      public void onErrorResponse(VolleyError error) { 

      } 
     }); 

     requestQueue.add(jsonArrayRequest); 

    } 

private String[] parsejsonResponse(JSONArray array){ 

     String[] banks; 

     if (array!= null){ 
      JSONArray data=array.getJSONArray("data"); 

      for (int i=0;i<data.length();i++){ 
       try { 
         JSONObject bank=data.getJSONObject(i); 

         String id=bank.getString("id"); 
         String bankname=bank.getString("bankname") 

         banks.add(bankname); 

        } 

       } catch (JSONException e) { 

       } 

      } 
     } 

     return banks; 

    } 

Format json wie diese exemple:

[{ 
    "status": "success", 
    "message": "banks Fetched", 
    "data": [ 
     { 
      "id": 214, 
      "bankname": "FIRST CITY MONUMENT BANK PLC" 
     }, 
     { 
      "id": 215, 
      "bankname": "UNITY BANK PLC" 
     }, 
     { 
      "id": 221, 
      "bankname": "STANBIC IBTC BANK PLC" 
     }, 
     { 
      "id": 232, 
      "bankname": "STERLING BANK PLC" 
     }, 
     { 
      "id": 301, 
      "bankname": "JAIZ BANK" 
     }, 
     { 
      "id": 304, 
      "bankname": "Stanbic Mobile" 
     }, 
     { 
      "id": 305, 
      "bankname": "PAYCOM" 
     } 
    ] 
}] 

In oncreate nur cal sendjsonrequest() Methode
