Android的JSON解析器陣列

public class MainActivity extends Activity { 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     setContentView(R.layout.activity_main); 

     new Read().execute("masjids"); 

    } 

    public JSONObject retrieveInfo(String radius) throws ClientProtocolException, 
      IOException, JSONException { 
     StringBuilder url = new StringBuilder(
       "http://iqamah.org/api/index.php?lat=43&long=-79&radius="); 
     url.append(radius); 

     HttpClient httpclient = new DefaultHttpClient(); 
     HttpGet get = new HttpGet(url.toString()); 
     HttpResponse r = httpclient.execute(get); 
     HttpEntity e = r.getEntity(); 
     String data = EntityUtils.toString(e); 
     JSONObject timeline = new JSONObject(data); 
     return timeline.getJSONObject("1"); 
    } 

    private class Read extends AsyncTask<String, Integer, String> { 

     ProgressDialog pd = null; 

     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      pd = new ProgressDialog(MainActivity.this); 
      pd.setTitle("Loading..."); 
      pd.setMessage("Please wait..."); 
      pd.setCancelable(false); 
      pd.show(); 

     } 

     protected String doInBackground(String... arg0) { 
      // TODO Auto-generated method stub 
      try { 
       JSONObject json = retrieveInfo("200"); 
       return json.getString(arg0[0]); 
      } catch (ClientProtocolException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (JSONException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      return null; 
     } 

     @Override 
     protected void onPostExecute(String status) { 
      super.onPostExecute(status); 
      pd.dismiss(); 

      TextView day = (TextView) findViewById(R.id.displayDay); 
      day.setText("Masjid: " + status); 

     } 

    } 

}

的JSON：

{ 
    "status": "ok", 
    "masjids": [ 
     { 
      "id": "44|Madina Masjid|1200 Danforth Ave, Toronto|49.99" 
     }, 
     { 
      "id": "39|Darul Taqwa|1 Thorncliffe Park Drive, Toronto|51.59" 
     }, 
     { 
      "id": "43|Darul Khair|25 St Dennis, Toronto|52.12" 
     } 
    ] 
}

我試圖訪問masjids->id[0]陣列，我怎麼能做到這一點與上面的代碼？

嗯..閱讀的JSONObject文檔以及如何使用它在陣列的情況下。 – 2013-03-01 04:48:48

檢查一下，我幾天前回答了一個類似的問題，你可以根據你的回答調整答案。 http://stackoverflow.com/questions/13576676/how-to-parse-complex-json-file-in-android/13576784#13576784希望它有幫助。 – Atrix1987 2013-03-01 05:48:34

String data = "{ "status": "ok", "masjids": [ { "id": "44|Madina Masjid|1200 Danforth Ave, Toronto|49.99" }, { "id": "39|Darul Taqwa|1 Thorncliffe Park Drive, Toronto|51.59" }, { "id": "43|Darul Khair|25 St Dennis, Toronto|52.12" } ] }"; 

JSONObject jObj = new JSONObject(data); 
JSONArray jArray_masjids = jObj.getJSONArray("masjids"); 
String address = jArray_masjids.getJSONObject(0).getString("id");

JSONObject timeline = new JSONObject(data); 
JasonArry jarry=timeline.getJsonArray("masjids"); 
for (int i = 0; i < jarry.length(); i++) { 
JSONObject explrObject = jsonArray.getJSONObject(i); 
String newStr = explrObject.getString("id"); 
}

試試這個，

String data = "{ "status": "ok", "masjids": [ { "id": "44|Madina Masjid|1200 Danforth Ave,  Toronto|49.99" }, { "id": "39|Darul Taqwa|1 Thorncliffe Park Drive, Toronto|51.59" }, { "id": "43|Darul Khair|25 St Dennis, Toronto|52.12" } ] }"; 

JSONObject jObj = new JSONObject(data); 
JSONArray jArray_masjids = jObj.getJSONArray("masjids"); 
for(int i = 0 ;i<jArray_masjids;i++){ 
String address = jsonArray.getJSONObject(i).getString("id"); 

}
