How to implement on click in cardview + recycler view with firebase?

I have implemented a cardview along with a recyclerview that fetch data from firebase. I want to implement onclick methods to cards that goes for different activities. How can i add on click method for the cards? Here is my mainactivity.
public class English extends AppCompatActivity {
ViewHolder apt;
RecyclerView mRecyclerView;
FirebaseDatabase mFirebaseDatabase;
DatabaseReference mRef;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_english);
mRecyclerView = findViewById(R.id.recyclerView);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mFirebaseDatabase = FirebaseDatabase.getInstance();
mRef = mFirebaseDatabase.getReference("English");
}
private void firebaseSearch(String searchText){
Query firebaseSearchQuery=mRef.orderByChild("artist").startAt(searchText).endAt(searchText + "\uf8ff");
FirebaseRecyclerAdapter<englishacti, ViewHolder> firebaseRecyclerAdapter=new FirebaseRecyclerAdapter<englishacti, ViewHolder>(englishacti.class,R.layout.row,ViewHolder.class,firebaseSearchQuery) {
#Override
protected void populateViewHolder(ViewHolder holder, englishacti model, int position) {
holder.setDetails(getApplicationContext(),model.getAlbum(),model.getDescription(),model.getImage(),model.getArtist());
}
};
mRecyclerView.setAdapter(firebaseRecyclerAdapter);
}
#Override
protected void onStart() {
super.onStart();
FirebaseRecyclerAdapter<englishacti,ViewHolder> firebaseRecyclerAdapter;
firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<englishacti, ViewHolder>(englishacti.class,R.layout.row,ViewHolder.class,mRef) {
#Override
protected void populateViewHolder(ViewHolder viewHolder, englishacti model, int position) {
viewHolder.setDetails(getApplicationContext(), model.getAlbum(), model.getDescription(), model.getImage(), model.getArtist());
}
};
mRecyclerView.setAdapter(firebaseRecyclerAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu,menu);
MenuItem item = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
firebaseSearch(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
firebaseSearch(newText);
return false;
}
});
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id=item.getItemId();
if (id==R.id.action_settings){
return true;
}
return super.onOptionsItemSelected(item);
}
}

please take a look at my snipshed code, in my case i use this way to implement setonlclick in recycleview item and send value to other activity
holder.setName(userName);
holder.setUserImage(userThumb, getContext());
holder.mView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent chatIntent = new Intent(getContext(), Tampung_chatActivity.class);
chatIntent.putExtra("user_id", list_user_id);
chatIntent.putExtra("user_name", userName);
startActivity(chatIntent);
}
});
full code you can see at here :

Skipped 98 frames! The application may be doing too much work on its main thread

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.

Android autocompletion view using retrofit

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

Here is code example of using Retrofit with AutocompleteEditText
public class MainActivity extends Activity {

Half of the lifecycle methods of fragment get not called after rotation

I'm experiencing an strange behavior of Fragment life-cycle each time that i rotate the screen. Only the first half of life-cycle methods are getting called, onPause,onSaveInstanceState,onStop, onDestroyView,onDestroy and onDetach. The other half (onAttach ...-onResume) are not getting called. The Activity associated with the Fragment is calling all its life-cycle methods.
Any help would be highly appreciated because I'm stuck on this issue.
Thanks in advance.
Here the entire code of the Activity and the static nested class where is the Fragment:
public class MoviesFeed extends AppCompatActivity {

#Override

//the detail_activity_container will be present only in large-screen
//Layouts (res/Layout-sw600dp. If this view is present, then the activity
//should be in two-pane mode
mTwoPane=true;
//In two-pane mode, show the detail view in this activity by adding
// or replacing the detail fragment using a fragment transaction
DetailActivityFragment detailActivityFragment=new DetailActivityFragment();
// Bundle bundle=new Bundle();
// bundle.putBoolean("twopane",mTwoPane);
// detailActivityFragment.setArguments(bundle);

How to add ProgressBar in android

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!
