私は初めてでJSON、次の例外が発生しています：

org.json.JSONArray cannot be converted to JSONObjecttry セクション自体の最初の行に。

これを削除するのを手伝ってください。これが私のコードです：

try {   
    JSONObject json = new JSONObject(strResponse);

    //Get the element that holds the internship ( JSONArray )
    JSONArray name = json.names();
    JSONArray  internships = json.toJSONArray(name);

    //Loop the Array
    for(int i=0;i < internships.length();i++) {     
        Log.e("Message","loop");
        HashMap<String, String> map = new HashMap<String, String>();
        JSONObject e = internships.getJSONObject(i);
        map.put("id",  String.valueOf("id"));
        map.put("title", "Title :" + e.getString("title"));
        map.put("company", "Company : " +  e.getString("company"));
        map.put("category", "Category : " +  e.getString("category"));
        mylist.add(map);
    } 
} catch(JSONException e) {
    Log.e("log_tag", "Error parsing data "+e.toString());
}

これは、phpファイルから取得しているjsonです

おそらく次のように初期化する必要がありjsonますJSONArray。

JSONObject json = new JSONObject(strResponse);

次に、次のようにする必要があります。

JSONArray json = new JSONArray(strResponse);

ただし、次の 2 つの操作では機能しません。

JSONArray name = json.names(); //.names() doesn't exist in JSONArray
JSONArray  internships = json.toJSONArray(name); // Is instead to be seen as

JSONObject代わりにfromを取得するようにループを変更するだけで問題ありませんjson(したがって、 への依存関係を削除し.names()ます:

JSONObject e = json.getJSONObject(i);

編集：完全なコード

try {   
    JSONArray internships = new JSONArray(strResponse);

    //Loop the Array
    for(int i=0;i < internships.length();i++) {     
        Log.e("Message","loop");
        HashMap<String, String> map = new HashMap<String, String>();
        JSONObject e = internships.getJSONObject(i);
        map.put("id",  String.valueOf("id"));
        map.put("title", "Title :" + e.getString("title"));
        map.put("company", "Company : " +  e.getString("company"));
        map.put("category", "Category : " +  e.getString("category"));
        mylist.add(map);
    } 
} catch(JSONException e) {
    Log.e("log_tag", "Error parsing data "+e.toString());
}

問題：

 JSONObject json = new JSONObject(strResponse);

ここでは、 への変換中にこの例外が発生するためstrResponse、 の形式になっている可能性があります。JSONArrayJSONObject
