Return button to previous activity with BaseAdapter

Return button to previous activity with BaseAdapter - android

I currently have two activities doing HTTP requests.
The first activity contains a CustomList class extends BaseAdapter.
On the second, there is a previous button allowing me to return to the first activity.
Returning to the first activity, I would like to be able to recover the state in which I left it. That is to say to be able to find the information which also come from an HTTP request. I would like to find the data "infos_user" which is in the first activity and all the data in the BaseAdapter.
My architecture is as follows: Activity 0 (HTTP request) -> Activity 1 (with BaseAdapter and HTTP request) -> Activity 2 (HTTP request)
I put all the code because I really don't know how can I do this :/
First activity:
public class GetChildrenList extends AppCompatActivity implements View.OnClickListener {
private ArrayList<Child> childrenImeList = new ArrayList<Child>();
private Button btn_previous;
private ListView itemsListView;
private TextView tv_signin_success;
int id = 0;
String infos_user;
String email;
String password;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.get_children_list);
infos_user = (String) getIntent().getSerializableExtra("infos_user");
Intent intent = new Intent(GetChildrenList.this , GetLearningGoalsList.class);
intent.putExtra("username", infos_user);
btn_previous = (Button) findViewById(R.id.btn_previous);
btn_previous.setOnClickListener(this);
tv_signin_success = (TextView) findViewById(R.id.tv_signin_success);
tv_signin_success.setText("Bonjour " + infos_user + "!");
itemsListView = (ListView)findViewById(R.id.list_view_children);
new GetChildrenAsync().execute();
}
class GetChildrenAsync extends AsyncTask<String, Void, ArrayList<Child>> {

#Override

super.onPreExecute();
loadingDialog = ProgressDialog.show(GetChildrenList.this, "Please wait", "Loading...");
}
#Override
protected ArrayList<Child> doInBackground(String... params) {
int age = 0;
email = (String) getIntent().getSerializableExtra("email");
password = (String) getIntent().getSerializableExtra("password");
String first_name = null;
String last_name = null;
try {
SendRequest sr = new SendRequest();
String result = sr.sendHttpRequest("http://" + sr.getIP_ADDRESS() + "/childrenime/list", "GET", true, email, password);
String jsonResult = "{ \"children\":" + result + "}";
Log.d("result1", jsonResult);
//Manage JSON result
JSONObject jsonObject = new JSONObject(jsonResult);

String name = first_name + " " + last_name;
childrenImeList.add(new Child(id,name,age));
}
} catch (JSONException e) {

}
#Override

BaseAdapter:

#Override

#Override

String email = (String) ((Activity) context).getIntent().getSerializableExtra("email");

Intent intent = new Intent(context, GetLearningGoalsList.class);

Second Activity:

private Button btn_previous;

}
}
Thanks for your help.

if you want to maintain GetChildrenList state as it is then just call finish() rather than new intent on previous button click as follow
replace in GetLearningGoalsList
#Override
public void onClick(View v) {
Intent myIntent = new Intent(GetLearningGoalsList.this, GetChildrenList.class);
myIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(myIntent);
return;
}
with
#Override
public void onClick(View v) {
finish();
}

Here I am not able to get user_id using shared preference. Please help me how to get it.

In onPostExecute try this you will get User ID
try {
String userid;
JSONObject ob = new JSONObject(jsonstring);
JSONArray arr = ob.getJSONArray("VerifiedMember");
for (int i = 0; i < arr.length(); i++) {
JSONObject obj = arr.getJSONObject(i);
userid=obj.getString("user_id");
}
} catch (Exception e) {
}

You can use this pojo generator
http://www.jsonschema2pojo.org/
For parsing you can use google's gson library or jackson parser is also good.

The problem is that I wanna add data from Asynctask and shown on another adapter. But how can i do that? please help. view from another adapter couldn't show with this code.

Transaction ID set correctly, but displayed only a submit later

My code gives correct response and sets transaction ID correctly. But on screen, the ID is missing the first time I submit, and when I go back and submit again, then the ID on screen is the ID of the first transaction.
On the first submit, this is rendered:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID:
On the second submit, this is rendered:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID: NUFEC37WD537K5K2P9WX
I want to see the second screen the first time I submit.
Response to the first submit:
D/TID IS: ====>NUFEC37WD537K5K2P9WX D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"NUFEC37WD537K5K2P9WX","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}
Response to the second submit:
D/TID IS: ====>18R6YXM82345655ZL3E2 D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"18R6YXM82345655ZL3E2","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}

Because you have used Volley library which is already asynchronous, you don't have to use AsyncTask anymore.
Your code can be updated as the following (not inside AsyncTask, direct inside onCreate for example), pay attention to // update TextViews here...:
...
String url = "http://www.example.com/index.php";
RequestQueue requestQueue = Volley.newRequestQueue(this);
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject json_Response = new JSONObject(response);
String _TID = json_Response.getString("tid");
String _uid = json_Response.getString("uid");
String _status = json_Response.getString("status");
String tid_m =mytid.setTId_name(_TID);
Log.d("TID IS","====>"+tid_m);
Log.d("UID IS","====>"+_uid);
// update TextViews here...
txtTransId.setText(_TID);
txtStatus.setText(_status);
...
} catch (JSONException e) {
e.printStackTrace();
}
Log.d("Response-------", "------>" + response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Responce error==","===>"+error);
error.printStackTrace();
}
}
requestQueue.add(postRequest);
...
P/S: since the reponse data is a JSONObject, so I suggest you use JsonObjectRequest instead of StringRequest. You can read more at Google's documentation.
Hope it helps!

Your line of code should be executed after complete execution of network operation and control comes in onPostExecute(); of your AsyncTask.
confirm_tId.setText(_tid);

how to display dynamic spinner values in android

I think the problem is you aren't calling the super class of notifyDataSetChanged(), maybe try
#Override
public void notifyDataSetChanged() {
rows.clear();
for (HashMap<String, String> addvert : data) {
rows.add(new MyAddActivateRow((LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE), addvert));
Log.d("MyActivateAdapter", "update " + data.size());
}
super.notifyDataSetChanged();
}
