i want to when run the app make the jsonRequest without pressing any button and save the data. i just add a method for internet connection check:
if the connection to the internet its true, make the json request pass to the spinner, and save de data.
and when the internet connection its false, just load the data from sharedPreferences to the spinner.
The application runs totally fine with the buttons (with simple onClick methods) and without the verificaConexion method.
But when i remove the buttons, add the verificaConexion method and i have internet connection, just, make the json request, show the data in the spinner and not save the data And when I close the app, remove the wifi, open the app, the spinner shows nothing.
For any reason the methods save and load data doesn't works.
This is my onCreate()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnObtener = (Button) findViewById(R.id.btnObtener);
spDelegaciones = (Spinner)findViewById(R.id.spDelegaciones);
btnGuardar = (Button) findViewById(R.id.btnGuardar);
btnCargar = (Button) findViewById(R.id.btnCargar);
txJsonArray = (TextView) findViewById(R.id.txJsonArray);
verificaConexion(this);
}
This is my json Request method, works fine:
public void request() {
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(json_url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray jsonArray) {
Log.e("jsonArray", "" + jsonArray);
if (jsonArray == null) {
Toast.makeText(MainActivity.this, "EL JSONArray esta VACIO !!! ", Toast.LENGTH_SHORT).show();
} else {
for (int i = 0; i < jsonArray.length(); i++) {
try {
JSONObject jsonObject = jsonArray.getJSONObject(i);
//con el php JsonArrayRequest2.php
// String contact = jsonObject.getString("delegacion");
//con el php JsonArrayVariosCampos.php
String contact = jsonObject.getString("Delegacion");
arrayList.add(contact);
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter.notifyDataSetChanged();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "ERROR...", Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
});
RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this);
requestQueue.add(jsonArrayRequest);
}
my guardarDatos method to save the data:
public boolean guardarDatos(){
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor mEdit1 = sp.edit();
/* sKey is an array */
mEdit1.putInt("Status_size", arrayList.size());
for(int i=0;i<arrayList.size();i++)
{
mEdit1.remove("Status_" + i);
mEdit1.putString("Status_" + i, arrayList.get(i));
}
Toast.makeText(MainActivity.this, " DATOS GUARDADOS ", Toast.LENGTH_SHORT).show();
return mEdit1.commit();
}
and my cargarDatos method to load the data:
public void cargarDatos(){
SharedPreferences mSharedPreference1 = PreferenceManager.getDefaultSharedPreferences(this);
arrayList.clear();
int size = mSharedPreference1.getInt("Status_size", 0);
for(int i=0;i<size;i++)
{
arrayList.add(mSharedPreference1.getString("Status_" + i, null));
}
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, arrayList);
spDelegaciones.setAdapter(adapter);
Toast.makeText(MainActivity.this, " DATOS CARGADOS ", Toast.LENGTH_SHORT).show();
}
and here is my class to check the internet connection:
public boolean verificaConexion(Context ctx){
boolean bConectado = false;
ConnectivityManager connec = (ConnectivityManager) ctx.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo[] redes = connec.getAllNetworkInfo();
for (int i = 0; i < 2; i++) {
if (redes[i].getState() == NetworkInfo.State.CONNECTED) {
bConectado = true;
if(bConectado) {
Toast.makeText(MainActivity.this, " con conexion ", Toast.LENGTH_LONG).show();
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, arrayList);
spDelegaciones.setAdapter(adapter);
request();
guardarDatos();
}else {
cargarDatos();
}
}else{
}
}
return bConectado;
}
Since you are using only one string in contact class. instead of arrayList<Contact> I will use ArrayList<String>
here I have removed singleTone class. and added jsonArrayRequest code inside in same class. and after adding item in arraylist I have called adapter.notifyDataSetChanged();
MainActivity.class
public class MainActivity extends AppCompatActivity {
TextView txdeleg_lista;
Button btnObtener;
ArrayList<String> arrayList = new ArrayList<String>();
ListView listView;
String json_url = "your url";
ArrayAdapter<String> adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnObtener = (Button) findViewById(R.id.btnObtener);
txdeleg_lista = (TextView) findViewById(R.id.txdeleg_lista);
listView = (ListView) findViewById(R.id.lvDelegacion);
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, arrayList);
btnObtener.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//startActivity(new Intent(MainActivity.this, DesplegarLista.class));
listView.setAdapter(adapter);
request();
}
});
}
public void request() {
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(json_url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray jsonArray) {
Log.e("jsonArray",""+jsonArray);
if(jsonArray == null){
Toast.makeText(MainActivity.this,"EL JSONArray esta VACIO !!! ", Toast.LENGTH_SHORT).show();
}
else {
for (int i = 0; i < jsonArray.length(); i++) {
try {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String contact = jsonObject.getString("UFULLNAME");
arrayList.add(contact);
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter.notifyDataSetChanged();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this,"ERROR...", Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
});
RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this);
requestQueue.add(jsonArrayRequest);
}
}
check and if you have any query comment.

I have tried setting an empty adapter first inside of onCreate() and adapter.notifyDataSetChanged(); after I get the data in my praseJSON() but still no luck!
Everything in the Recycler adapter file is also set according to all the fix is found online.

The problem is that you've set the adapter mNearbyAdapter before creating the NearbyAdapter object.
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_nearby);
mRecyclerView = findViewById(R.id.recyclerViewNearby);
// you passed mNearbyAdapter here
mRecyclerView.setAdapter(mNearbyAdapter);
// but you created the object for it here
mNearbyAdapter = new NearbyAdapter(NearbyActivity.this, mNearbyList);
...
To fix this, create the object for your adapter first, then call setAdapter(mNearbyAdapter).
I am working on an android application. In this application, I have to retrieve data from a web service and put it in a listview, but it is not retrieving anything. I don't know what I am doing wrong here. Maybe someone can help me with this.

Im using volley to download the JSON data from a server, setting the Adapter within the function that reads and parses the data. However, the adapter is not being recognized. The problem is, I have successfully implemented the adapter in another activity with the same method without errors. The following is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();
if (extras!=null) {
user_id = getIntent().getStringExtra("user_id");
} else {
Intent logIn = new Intent(JoinedActivity.this, LoginActivity.class);
startActivity(logIn);
}
setContentView(R.layout.activity_joined);
recyclerView = (RecyclerView) findViewById(R.id.recyclerView1);
recyclerView.addItemDecoration(new SimpleDividerItemDecoration(this));
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
GetJoinedEvents();
}
public void GetJoinedEvents(){
String tag_string_req = "req_getJoinedEvents";
StringRequest stringRequest = new StringRequest(Request.Method.GET, Config.URL_USER_lIST_EVENTS+user_id, new Response.Listener<String>(){
#Override
public void onResponse(String response) {
// progressDialog.dismiss();
Log.i("responseTest",response);
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray result = jsonObject.getJSONArray(Config.TAG_JSON_ARRAY);
int length = result.length();
HashMap<String, String> events;
for (int i = 0; i < length; i++) {
JSONObject jo = result.getJSONObject(i);
String event_id = jo.getString(Config.TAG_EVENT_ID);
String name = jo.getString(Config.TAG_EVENT_NAME);
String date = jo.getString(Config.TAG_EVENT_START_DT);
String weekday = jo.getString(Config.TAG_EVENT_WEEKDAY);
String event_type = jo.getString(Config.TAG_EVENT_TYPE);
events = new HashMap<>();

events.put(Config.TAG_EVENT_WEEKDAY, weekday);
events.put(Config.TAG_EVENT_TYPE, event_type);
eventList.add(events);
}
listAdapter = new RecyclerViewAdapter(JoinedActivity.this,eventList, user_id);
recyclerView.setAdapter(listAdapter);
}
catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Error", "Bad internet connection");
}
}) {};
AppController.getInstance().addToRequestQueue(stringRequest, tag_string_req);
Log.i("URL", stringRequest.toString());
}
}
A better approach to this is just to initialize the Recycler view and adapter on the onCreate. Then later on when you have the data you could create a swapItems method just for the purpose of changing the data within the recyclerview through the adapter, but in a way that both the RecyclerView and its adapter is instantiated as the activity starts.
on your swapItems you could do something like below:
public void swapItems(List<Events> eventList) {
if (eventList != null) {
this.items = eventList;
notifyDataSetChanged();// should call this to let the recyclerview know that our data set has changed
}
}
Then you could just call it via the activity by
listAdapter.swapItems(eventList);// this is done the moment you already got your list of events
While submitting data from editTexts of Dialog box whose context is in Home activity, the submitted button doing nothing.
host is a button on home activity,when clicked opens up a dialog box in same activity consists of two editText field (ename,eemail) and submit , cancel button. On submit getFeedback() functions called (used from ApiInterface method)
host.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view)
{
final Dialog d=new Dialog(context);
d.setCanceledOnTouchOutside(false);
d.setContentView(R.layout.hostdialog);
d.getWindow().setBackgroundDrawableResource(R.drawable.bgdialog);
final EditText ename=(EditText)d.findViewById(R.id.ename);
final EditText eemail=(EditText)d.findViewById(R.id.eemail);
final Button submit=(Button)d.findViewById(R.id.submit);
final Button clear=(Button)d.findViewById(R.id.clear);
submit.setOnClickListener(new View.OnClickListener() {
#SuppressLint("WrongConstant")
#Override
public void onClick(View view) {
try {
getFeedbacks(ename.getText().toString(),eemail.getText().toString());
d.dismiss();
Toast t = Toast.makeText(getApplicationContext()," ✓ Thank You, We'll contact you soon",Toast.LENGTH_LONG);
View v = t.getView();
v.setBackgroundResource(R.drawable.clear);
t.show();
} catch (Exception e) {

}
}
});
clear.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
d.dismiss();
}
});
d.show();
}
});
and my ApiInterface code is:
#GET("myurl")
Call<JsonElement> getFeedbacks(#Body RequestBody requestBody);
getFeedback method consist of:-
private void getFeedbacks(String user_name, String user_email){
JSONObject paramobject = new JSONObject();
try {

Check your hostdialog.xml file
-button id is "submit" or not
may be that id is diffrent so the code is not working
