how to loop the JSON and print all the keys and values.

Answer 1

You can simply parse the Json string as below -

String json_string_from_server = "{"test1":"test1_value","test2":"test2_value"}";

JSONObject jObj = new JSONObject(json_string_from_server);
String val_Test1 = jObj.getString("test1");
String val_Test2 = jObj.getString("test2");

case 2:

String json_string_from_server = "{ 
  "result" : [
    {"test1":"test1_values_baru", "test2":"test2_values"}, 
    {"test1":"test??1_values", "test2":"test2_values"}
  ]
}";

JSONObject jObj = new JSONObject(json_string_from_server);
JSONArray jResultArray = jObj.getJSONArray("result");
for(int i=0; i<jResultArray.length(); i++){
    JSONObject jResultObj = jResultArray.getJSONObject(i);
    String val_Test1 = jResultObj.getString("test1");
    String val_Test2 = jResultObj.getString("test2");
}
