I'm not sure how to add a progress bar or make a loading dialog while the data is being retrieved from parse.
This is my code below for retrieving the data from parse. I've tried few tutorials but none have seemed to work for me.
public class HolidayActivity extends AppCompatActivity {
private HolidayAdapter mAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_holiday);
//noinspection ConstantConditions
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setIcon(R.drawable.dl);
ParseObject.registerSubclass(Holiday.class);
mAdapter = new HolidayAdapter(this, new ArrayList<Holiday>());
ListView mListView = (ListView) findViewById(R.id.holiday_list);
mListView.setAdapter(mAdapter);
updateData();
}
public void updateData() {
ParseQuery<Holiday> query = ParseQuery.getQuery(Holiday.class);
query.setCachePolicy(ParseQuery.CachePolicy.CACHE_THEN_NETWORK);
query.findInBackground(new FindCallback<Holiday>() {
#Override
public void done(List<Holiday> holidays, com.parse.ParseException e) {
if (holidays != null) {
mAdapter.clear();
for (int i = 0; i < holidays.size(); i++) {
mAdapter.add(holidays.get(i));
}
}
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// app icon in action bar clicked; goto parent activity.
this.finish();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
Add this to your updateData():
public void updateData() {
final ProgressDialog progressDialog = ProgressDialog.show(this, null, "Loading…");
(…)
#Override
public void done(List<Holiday> holidays, com.parse.ParseException e) {
progressDialog.dismiss();
(…)
}
}
Hope it helps!

I have navigationdrawer with nav menus. When clicking on each nav menus, specific fragment opened. Each fragment display recylerviews who fetch data from SQLite external database.Now when open new fragment, little seconds must wait and when to click on each item for go to next activity for display details information about the item, 5 seconds must wait to open Details Activity. I know this is a problem for fetching data in main Thread and fetch bitmap in the main thread.But I don't know how to solve this problem with use AsyncTask.My big problem is an open new activity for display information and waiting for 5 seconds.
This is my asiafragment.

Please help me, good friends. Thanks
i want to query results from custom adapter by comparing query text with list in RecycleView, it successfully gets results from query then i make list of results and update the existing adapter but it does not effect anything, i use below code fot that
combinationMessagesList = createCombinationMessagesList();
combinationMessages = createCombinationMessagesList();
combinationMessages.clear();
for (int i = 0; i < combinationMessagesList.size(); i++) {
CombinationMessage message = combinationMessagesList.get(i);
if (message.getBody().toString().equals(search.getText().toString())){
combinationMessages.add(combinationMessagesList.get(i));

I'm trying to understand how to implement a search with chips (so there should be the chance to add more than one value) and the suggestion list should come from a web service using Retrofit. An example on what I would like to achieve is the search in Pinterest app.
I read online many post where someone uses AutoCompleteTextView and other SearchView and to be honest I'm very confused on which approach to follow.
Could you address me to the right way please?
Thanks

I'm trying to get working a native android project that uses Worklight form based authentication. I'm already able to authenticate the user through the native APIs. The problem appears when I change between activities (intents). Once the user enters his information and submits the form, it is authenticated but the worklight server connection is lost.
This is the code:
MainActivity.java
public class MainActivity extends Activity {
private Button buttonConnect = null;
private Button buttonInvoke = null;
private static TextView textView = null;
private static MainActivity _this;
private MyChallengeHadler challengeHandler;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
_this = this;
buttonConnect = (Button)findViewById(R.id.buttonConnect);
buttonInvoke = (Button)findViewById(R.id.buttonInvoke);

I have already solved my code's problem. I was using wrongly android's intents. This is the new version of the code:
LoginActivity.java
public class LoginActivity extends Activity {
private Button Submit;
private Intent result;
public static final String Back = "back";
public static final String UserNameExtra = "username";
public static final String PasswordExtra = "password";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Submit = (Button)findViewById(R.id.button1);
result = new Intent();
Submit.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
result.putExtra(UserNameExtra, "maria");
result.putExtra(PasswordExtra, "maria");
result.putExtra(Back, false);
setResult(RESULT_OK, result);
finish();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.login, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
