安卓排球JsonPars異常

我是新手安卓，並對Volley做了一些練習。我寫的示例代碼：安卓排球JsonPars異常

RequestQueue rq = Volley.newRequestQueue(this); 
    String urlStr="https://api.github.com/users/mralexgray/repos"; 
    JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
      com.android.volley.Request.Method.GET,urlStr, null, 
      new Response.Listener<JSONObject>() { 

       @Override 
       public void onResponse(JSONObject response) { 

        Log.d("Response", response.toString()); 
       } 
      }, new Response.ErrorListener() { 

       @Override 
       public void onErrorResponse(VolleyError error) { 
        // TODO Auto-generated method stub 
        Toast.makeText(MainActivity.this, error.toString(), 
          Toast.LENGTH_LONG).show(); 
        Log.d("Error!!!!", error.toString()); 
       } 
      }); 
    rq.add(jsonObjectRequest);

但程序引發異常：

我如何解決這個錯誤？

你貼是JsonArray，不是一個JSONObject的JSON的部分，對於初學者。此外，它看起來像混合了JSONObject和JsonObject類，這可能會導致問題，因爲它們不是同一件事。我無法確切地告訴你錯誤來自哪裏，因爲我看到了幾處可能失敗的地方，並且你沒有發佈完整跟蹤，但如果響應是一個數組並且確保不要混合組織，請嘗試請求一個JsonArray。 json和com.google.gson類。 – Turnsole

的響應是一個JSON數組不是JSON對象，所以修改凌空請求方法如下

RequestQueue rq = Volley.newRequestQueue(this); 
    String urlStr = "https://api.github.com/users/mralexgray/repos"; 
    JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(urlStr, 
      new Response.Listener<JSONArray>() { 

       @Override 
       public void onResponse(JSONArray response) { 
        // TODO Auto-generated method stub 
        Log.d("Response", response.toString()); 
       } 

      }, new Response.ErrorListener() { 

       @Override 
       public void onErrorResponse(VolleyError error) { 
        // TODO Auto-generated method stub 
        Toast.makeText(MainActivity.this, error.toString(), 
           Toast.LENGTH_LONG).show(); 
         Log.d("Error!!!!", error.toString()); 
       } 
      }); 
    rq.add(jsonArrayRequest);

這將幫助你
