JSON配列から現​​在のJSONオブジェクトキーを取得し、アンドロイドの別のアクティビティに渡すにはどうすればいいですか？

Question

JSON配列から現​​在のJSONオブジェクトキーを取得し、それを別のアクティビティに渡したいときに、アンドロイドのLinear Layout OnClick関数を使用します。私のJSON配列名extra_infoには3つのオブジェクトがありますmain_header 2番目のオブジェクトの文字列名があります.2番目のオブジェクトキーを取得してJSON配列からそのオブジェクトの内部フィールドを取得する必要があります。 JSON配列

から現在のJSONオブジェクトのインデックスを見つけるためにどのように

または他の私は多くのコードを検索しましたが、それらは、配列のすべてのオブジェクトキーを提供しています。 JSON

誰でもあなたはこのようなFetchDataことができ、事前

Answer 1

JSONArray arraydata = responseObj.getJSONArray("messages"); 

JSONObject mObject; 
for(int i = 0;i<arraydata.length();i++) { 
    mObject = arraydata.getJSONObject(i); 
    String MESAGE_DATA = mObject.getString("message_data"); 
    String USER_DATA = mObject.getString("user_data"); 


    JSONObject JSON_MSG_DATA = new JSONObject(MESAGE_DATA); 
    String MSG_ID = JSON_MSG_DATA.getString("message_id"); 
    String MSG_CUSTM_ID = JSON_MSG_DATA.getString("message_custom_id"); 
    String MSG_TEXT = JSON_MSG_DATA.getString("message_text"); 
    String SENDER_ID = JSON_MSG_DATA.getString("sender_id"); 
    String RECEIVER_ID = JSON_MSG_DATA.getString("receiver_id"); 
    String MSG_DATE_CREATED = JSON_MSG_DATA.getString("date_created"); 
    String MSG_DATE_UPDATED = JSON_MSG_DATA.getString("date_updated"); 
    String PARTNER_ID = JSON_MSG_DATA.getString("partner_id"); 
    String ELAPSED_TIME = JSON_MSG_DATA.getString("elapsed_time"); 


    JSONObject JSON_USER_DATA = new JSONObject(USER_DATA); 
    String USER_ID = JSON_USER_DATA.getString("user_id"); 
    String EMAIL = JSON_USER_DATA.getString("email"); 
    String USERNAME = JSON_USER_DATA.getString("username"); 
    String PASSWORD = JSON_USER_DATA.getString("password"); 
    String DEVICE_ID = JSON_USER_DATA.getString("device_id"); 
    String DEVICE_TYPE = JSON_USER_DATA.getString("device_type"); 
    String PROFILE_IMAGE = JSON_USER_DATA.getString("profile_image"); 
    String PHONE = JSON_USER_DATA.getString("phone"); 
    String GENDER = JSON_USER_DATA.getString("gender"); 
    String BIO = JSON_USER_DATA.getString("bio"); 
    String TITLE = JSON_USER_DATA.getString("title"); 
    String WEB_LINK = JSON_USER_DATA.getString("web_link"); 
    String STATUS = JSON_USER_DATA.getString("status"); 
    String USER_DATE_CREATED = JSON_USER_DATA.getString("date_created"); 
    String USER_DATE_UPDATED = JSON_USER_DATA.getString("date_updated"); 
}
