I have implemented Android Tab Layout. I have created five fragments named, one_fragment, two fragment....five fragment.
My XML name five_fragment.xml

Adapter in my Main Activity
private void setupViewPager(ViewPager viewPager) {
Adapter adapter = new Adapter(getSupportFragmentManager());
adapter.addFragment(new ListContentFragment(), "Screen1");
adapter.addFragment(new one_fragment(), "Screen2");
adapter.addFragment(new CardContentFragment(), "Screen3");
adapter.addFragment(new two_fragment(), "Screen4");
adapter.addFragment(new CardContentFragment(), "Screen5");
adapter.addFragment(new TileContentFragment(), "Screen6");
adapter.addFragment(new three_fragment(), "Screen7");
adapter.addFragment(new five_fragment(), "Feedback");
viewPager.setAdapter(adapter);
}
My five_fragment.java
public class five_feedback extends Fragment implements View.OnClickListener{
// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
public Button btn;
public EditText t1;
public EditText t2;
public EditText t3;
public five_feedback() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
btn = (Button) getView().findViewById(R.id.button01f);
t1 = (EditText) getView().findViewById(R.id.editText01) ;
t2 = (EditText) getView().findViewById(R.id.editText2) ;
t3 = (EditText) getView().findViewById(R.id.editText3) ;
btn.setOnClickListener(this);
return inflater.inflate(R.layout.five_fragment, container, false);
}
#Override
public void onClick(View v) {
if( t2.getText().toString().trim().equals("")){
Snackbar.make(v, "Email Required",
Snackbar.LENGTH_LONG).show();
} else {
String to = "pbharadwaj777#gmail.com";
String message = t2.getText().toString();
String subject = "Feedback";
Intent mEmail = new Intent(Intent.ACTION_SEND);
mEmail.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});
mEmail.putExtra(Intent.EXTRA_SUBJECT, subject);
mEmail.putExtra(Intent.EXTRA_TEXT, message);
// prompts to choose email client
mEmail.setType("message/rfc822");
startActivity(Intent.createChooser(mEmail, "Choose an email client to send your feedback!"));
}
}
}
When I install the open, I am able to open the app. I can slide from screen 1 to screen 7. However when I open Feedback, the app crashes. What is the issue?
The issue is you are trying to access the view before you actually inflated it. Change your onCreateView to the following or alternatively you could move your findViewById and setOnClickListener code to the onViewCreated function of the Fragment.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.five_fragment, container, false);
btn = (Button) view.findViewById(R.id.button01f);
t1 = (EditText) view.findViewById(R.id.editText01) ;
t2 = (EditText) view.findViewById(R.id.editText2) ;
t3 = (EditText) view.findViewById(R.id.editText3) ;
btn.setOnClickListener(this);
return view;
}

I am new to Android development and I am trying to send data via EditText to TextView from an alert dialog inflated in the MainActivity to a different activity (NewGame.java). I have tried intent.putExtra (see below) however I am getting null pointer exceptions as it seems I cannot access the views from the dialog layout xml file.
I know there are a few other ways to create an alert dialog so perhaps this way is not best for what i am trying to achieve?
MainActivity.java
public class MainActivity extends AppCompatActivity {
Button newGame, prevGames, newSquad, savedSquads;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
newGame = findViewById(R.id.buttonNewGame);
newGame.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
LayoutInflater inflater= getLayoutInflater();
builder.setView(R.layout.new_game_dialog);
final View myView= inflater.inflate(R.layout.new_game_dialog, null);
EditText enterTeam1, enterTeam2, enterDate, enterTime, enterLocation;
enterTeam1 = myView.findViewById(R.id.etTeam1);
enterTeam2 = myView.findViewById(R.id.etTeam2);
enterDate = myView.findViewById(R.id.etDate);
enterTime = myView.findViewById(R.id.etTime);
enterLocation = myView.findViewById(R.id.etLocation);
builder.setTitle("New Game")
.setCancelable(true)
.setPositiveButton("Start", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent intent = new Intent(MainActivity.this, NewGame.class);
intent.putExtra("TEAM1", enterTeam1.getText().toString());
intent.putExtra("TEAM2", enterTeam2.getText().toString());
intent.putExtra("DATE", enterDate.getText().toString());
intent.putExtra("TIME", enterTime.getText().toString());
intent.putExtra("LOCATION", enterLocation.getText().toString());
startActivity(intent);
}
})
.setNegativeButton("Cancel", null);
builder.create();
builder.show();
}
});
NewGame.java
public class NewGame extends AppCompatActivity {
TextView team1, team2, date, time, location;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_game);
team1 = findViewById(R.id.tvTeam1);
team2 = findViewById(R.id.tvTeam2);
date = findViewById(R.id.tvDate);
time = findViewById(R.id.tvTime);
location = findViewById(R.id.tvLocation);
team1.setText(getIntent().getStringExtra("TEAM1"));
team2.setText(getIntent().getStringExtra("TEAM2"));
date.setText(getIntent().getStringExtra("DATE"));
time.setText(getIntent().getStringExtra("TIME"));
location.setText(getIntent().getStringExtra("LOCATION"));
}
}

I believe you are having this problem because you are actually inflating 2 views. And referencing the wrong one when you use findById.
LayoutInflater inflater= getLayoutInflater();
builder.setView(R.layout.new_game_dialog);
final View myView= inflater.inflate(R.layout.new_game_dialog, null);
should look like this
LayoutInflater inflater= getLayoutInflater();
final View myView= inflater.inflate(R.layout.new_game_dialog, null);
builder.setView(myView);
I have set up a RecyclerView adapter with ViewPager in an activity namely TvShowEpisodeDetails , it works well but there is one issue, the Layout of RecyclerView is fixed while scrolling up and down in the Fragment(TvShowEpisodeDetailsFragment). But I want it to scroll with them.
The RecyclerView and ViewPager are both set inside viewpager_with_toolbar_overlay.xml Layout , and both has been settup in The Activity.
TvShowEpisodeDetailsFragment is the fragment class which belongs to activity class TvShowEpisodeDetails , the fragment creates as many episodes as a TV Show season can offer.
And off course this issue will be gone if I set RecyclerView adapter inside fragment, but I will get non-fixable highlighting and scrolling issues , that is why I set it inside the activity because it does not give those issues.
I need to make it work somehow inside the activity.
My goal is that RecyclerView and ViewPager has to be in the same layout XML file and they both must either be in the activity or fragment class
Is it possible to make the RecyclerView scroll with rest of the fragment layouts?
or
Is it possible to do it programmatically?
Here is the activity
public class TvShowEpisodeDetails extends MizActivity{
#Override
protected int getLayoutResource() {
return R.layout.viewpager_with_toolbar_overlay;
}
#Override
public void onCreate(Bundle savedInstanceState) {
mBus = MizuuApplication.getBus();
super.onCreate(savedInstanceState);
// Set theme
setTheme(R.style.Mizuu_Theme_NoBackground);
// setting episodeslist
final ArrayList<PlanetModel> episodeslist = new ArrayList<>();
for(TvShowEpisode e : mEpisodes){
episodeslist.add(new PlanetModel(e.mEpisode));
}
// setting RecyclerView
mEpisodesList = (RecyclerView) findViewById(R.id.episodesLIST);
// Setting LinearLayoutManager
LinearLayoutManager layoutManager
= new LinearLayoutManager(this.getApplicationContext(), LinearLayoutManager.HORIZONTAL, false);
//mEpisodesList.setLayoutManager(new LinearLayoutManager(mContext));
mEpisodesList.setLayoutManager(layoutManager);
// Setting RecyclerView Adapter
PlanetAdapter.OnItemClickListener indicatorCallback = new PlanetAdapter.OnItemClickListener() {
#Override
public void onItemClick(String item) {
SharedPreferences getPref = getContext().getSharedPreferences("PlanetAdapter", Context.MODE_PRIVATE);
int pos = getPref.getInt("newPosition", 0);
mViewPager.setCurrentItem(pos,false);
}
};
final PlanetAdapter planetAdapter = new PlanetAdapter(episodeslist,indicatorCallback);
mEpisodesList.setAdapter(planetAdapter);
// Setting ViewPager
mViewPager = (ViewPager) findViewById(R.id.awesomepager);
mViewPager.setAdapter(new TvShowEpisodeDetailsAdapter(getSupportFragmentManager()));
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
planetAdapter.setSelectedIndex(position);
planetAdapter.notifyDataSetChanged();
mEpisodesList.smoothScrollToPosition(position);
//mEpisodesList.scrollToPosition(position);
for (int i=0; i<episodeslist.size(); i++)
{
episodeslist.get(i).setPlanetSelected(false);
}
episodeslist.get(position).setPlanetSelected(true);
ViewUtils.updateToolbarBackground(TvShowEpisodeDetails.this, mToolbar, 0, mEpisodes.get(position).getTitle(), Color.TRANSPARENT);
}
});
if (savedInstanceState != null) {
mViewPager.setCurrentItem(savedInstanceState.getInt("tab", 0));
} else {
for (int i = 0; i < mEpisodes.size(); i++) {
if (mEpisodes.get(i).getSeason().equals(MizLib.addIndexZero(mSeason)) && mEpisodes.get(i).getEpisode().equals(MizLib.addIndexZero(mEpisode))) {
mViewPager.setCurrentItem(i);
break;
}
}
}
}

I have set up a RecyclerView adapter with ViewPager in an activity namely TvShowEpisodeDetails , it works well but there is one issue, the Layout of RecyclerView is fixed while scrolling up and down in the Fragment(TvShowEpisodeDetailsFragment). But I want it to scroll with them.
It's hard to use the RecyclerView outside of the ViewPager page fragment; because you can't synchronize and link the touch/motion events when you scroll the page up/down (or when you swipe to next/previous page) between both the page fragment and a standalone (i.e. activity) RecyclerView. Even that won't be smooth.
So, the RecyclerView should be a part of the ViewPager page.
And off course this issue will be gone if I set RecyclerView adapter inside fragment, but I will get unfixable highlighting and scrolling issues
So, now the issue of adding the RecyclerView in the ViewPager fragment is the highlighting issue of the RecyclerView item when you click on any item or when you swipe the ViewPager to right/left page.
But, the main issue is that there is a RecyclerView instance per page, i.e. if you have 5 pages, then you have 5 RecyclerViews.
So, it's a cumbersome to track highlighting only within the RecyclerView adapter class. And hence manipulating that with OnClickListeners solely will have issues of linking these RecyclerView and adapter instances together to update their highlighting item.
So, a simpler approach is to pass a parameter to the RecyclerView adapter with the selected item (which is definitely equals to the current ViewPager page position).
And then do a check in the onBindViewHolder() if the position equals to the passed-in value, then highlight the item; otherwise keep items with the original color.
So, wrapping this up into actions:
Change the adapter constructor to accept a highlighted_position parameter
public PlanetAdapter(ArrayList<PlanetModel> episodeslist,
int highlightedPosition, OnItemClickListener listener)
Whenever you create the ViewPager fragment using newInstance() pass-in the current position of the page fragment:
So, in the TvShowEpisodeDetails activity:
for (int i = 0; i < mEpisodes.size(); i++)
fragments.add(TvShowEpisodeDetailsFragment
.newInstance(mShowId,
Integer.parseInt(mEpisodes.get(i).getSeason()),
Integer.parseInt(mEpisodes.get(i).getEpisode()),
i)); // The position
And in the TvShowEpisodeDetailsFragment fragment, register this into a field in the fragment argument:
public static TvShowEpisodeDetailsFragment newInstance(String showId, int season, int episode, int position) { // adding position
TvShowEpisodeDetailsFragment pageFragment = new TvShowEpisodeDetailsFragment();
Bundle bundle = new Bundle();
// trimmed code.
bundle.putInt("position", position); // <<<< into the bundle
pageFragment.setArguments(bundle);
return pageFragment;
}
And set that in the adapter creation:
int currentPosition = getArguments().getInt("position");
planetAdapter = new PlanetAdapter(episodeslist, currentPosition, new PlanetAdapter.OnItemClickListener() {
#Override
public void onItemClick(final int pos) {
mCallback.sendText(pos);
}
});
And reflect that in the adapter to highlight the item:
public class PlanetAdapter extends RecyclerView.Adapter<PlanetAdapter.PlanetViewHolder> {
private final int highlightedPos;
public PlanetAdapter(ArrayList<PlanetModel> episodeslist, int highlightedPosition, OnItemClickListener listener) {
this.episodeslist = episodeslist;
this.listener = listener;
this.highlightedPos = highlightedPosition; // <<< set the position
}
#Override
public void onBindViewHolder(PlanetAdapter.PlanetViewHolder vh, final int position) {
TextView tv = (TextView) vh.itemView;
PlanetModel planetModel = episodeslist.get(position);
tv.setText(planetModel.getPlanetName());
tv.setCompoundDrawablesWithIntrinsicBounds(R.drawable.bg, 0, 0, 0);
if (highlightedPos == position) { //<<<<< Highlight the item
vh.itemView.setBackgroundColor(getContext().getResources().getColor(R.color.colorPrimaryLight));
Log.d("LOG_TAG", "onClick: Highlight item: " + highlightedPos);
} else {
vh.itemView.setBackgroundColor(getContext().getResources().getColor(R.color.colorPrimaryDark));
Log.d("LOG_TAG", "onClick: No highlight: " + highlightedPos);
}
}
}
I have 2 layouts where first layout for Fragment and second layout for RecyclerView. I have created CardView in RecyclerView, every CardView has some data. And I have created button below RecyclerView where the function of button for sending Data on CardView. My problem is I don't know how to send data when i click button in Fragment.

When i select RadioButton, only data in RadioButton will be obtained. And when i click button, the data will be send to another activity.
Adapter RecyclerView :
public class AdapterGetAddress extends RecyclerView.Adapter<AdapterGetAddress.ViewHolder> {
Context context;
private List<ModelGetAddress> modelGetAddressList;
private BaseApiService baseApiService;
private int previousSelected = -1;
public AdapterGetAddress(Context context, List<ModelGetAddress> modelGetAddressList) {
this.context = context;
this.modelGetAddressList = modelGetAddressList;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_address, parent, false);
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, final int position) {
final ModelGetAddress adapterAddress = modelGetAddressList.get(position);
}
#Override
public int getItemCount() {
return modelGetAddressList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private TextView nameUser, addressUser, streetName, blokAddressUser, cityAddressUser, countryUser, phoneUser;
private RadioButton radioButton;
public ViewHolder(#NonNull View itemView) {
super(itemView);
nameUser = itemView.findViewById(R.id.nameUser);
addressUser = itemView.findViewById(R.id.addressUser);
streetName = itemView.findViewById(R.id.streetName);
countryUser = itemView.findViewById(R.id.countryAddressUser);
blokAddressUser = itemView.findViewById(R.id.blokAddressUser);
cityAddressUser = itemView.findViewById(R.id.cityAddressUser);
phoneUser = itemView.findViewById(R.id.phoneUser);
radioButton = itemView.findViewById(R.id.radioButton);
radioButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
previousSelected = getAdapterPosition();
notifyItemRangeChanged(0, modelGetAddressList.size());
// I want this All String will be send when i click button in Fragment
String getNameUser = nameUser.getText().toString();
String getAddressUser = streetName.getText().toString();
String getCountryUser = countryUser.getText().toString();
String getBlokUser = blokAddressUser.getText().toString();
String getCityUser = cityAddressUser.getText().toString();
String getPhoneUser = phoneUser.getText().toString();
}
});
}
}
}
Code in Fragment :
public class MenuAddressFragment extends Fragment {
private Button gunakanAlamat;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_menu_address, container, false);
gunakanAlamat = view.findViewById(R.id.gunakanAlamat);
gunakanAlamat.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Here's were i'm stuck
}
});
return view;
}
}
You can solve this via an interface.
public interface ItemClickedCallback{
void onItemClicked(String nameUser //, the other data you wanna pass );
}
pass it through the constructor of your adapter.
Use this adapter constructor
ItemClickedCallback callback;
public AdapterGetAddress(Context context, List<ModelGetAddress> modelGetAddressList, ItemClickedCallback callback) {
this.context = context;
this.modelGetAddressList = modelGetAddressList;
this.callback= callback;
}
When checking a radio button of any item; call the interface method, like this.
radioButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
previousSelected = getAdapterPosition();
notifyItemRangeChanged(0, modelGetAddressList.size());
// I want this All String will be send when i click button in Fragment
String getNameUser = nameUser.getText().toString();
String getAddressUser = streetName.getText().toString();
String getCountryUser = countryUser.getText().toString();
String getBlokUser = blokAddressUser.getText().toString();
String getCityUser = cityAddressUser.getText().toString();
String getPhoneUser = phoneUser.getText().toString();
callback.onItemClicked(getNameUser //, the rest..);
}
});
Now, when you initialize the adapter in the fragment, create the new interface via the constructor and assign the data to class variables like this.
public class MenuAddressFragment extends Fragment {
private Button gunakanAlamat;
private String nameUser_;
// the rest...
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_menu_address, container, false);
AdapterGetAddress adapter = new AdapterGetAddress(getActivity, list, new ItemClickedCallback() {
#Override
public void onItemClicked(String userName //, the rest..) {
// assign to the class variable like this
nameUser_ = userName;
// the rest..
}
}););
gunakanAlamat = view.findViewById(R.id.gunakanAlamat);
gunakanAlamat.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Use the data as you want..
}
});
return view;
}
}

}
When the search Button is clicked, I want it to open the new activity and load the results there.
You can pass this searchText to the next Activity (I'm calling it ResultsActivity) by passing it as an extra on the Intent:
private void firebaseUserSearch(String searchText) {
Intent intent = new Intent(getActivity(), ResultsActivity.class);
intent.putExtra("searchText",searchText);
startActivity(intent);
}
Then receive it on the other Activity using Intent.getExtras():
String searchText = getIntent().getExtras().getString("searchText");
And finally populate the RecyclerView from that Activity:
Query firebaseSearchQuery = mUserDatabase.orderByChild("title").startAt(searchText).endAt(searchText + "\uf8ff");
FirebaseRecyclerAdapter<Cars, UsersViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Cars, UsersViewHolder>(
Cars.class,
R.layout.list_layout,
UsersViewHolder.class,
firebaseSearchQuery
) {

I am trying to add a listview to an existing android fragment. I made a layout xml file for items in the listview, modified the previous fragment.xml, wrote a new arrayadapter and added something to the fragment.java. But whenever I call the notifyDataSetChanged() method in the fragment.java, I got an error: android.content.res.Resources$NotFoundException: String resource ID #0x0, and then the app crashes. Below please find my codes.
layout.xml

recordArrayAdapter.notifyDataSetChanged();
}
}
}
Make sure checkInRec.providerName, checkInRec.checkInDate and checkInRec.providerPoints values that you set as TextView text have a type of String and cast it to String if it's integer.
// cast to String if checkInRec.checkInDate is integer
textViewPoints.setText(String.valueOf(checkInRec.providerPoints));
UPD:
It seems ListView is located behind header view. Try to change root view of fragment.xml from FrameLayout to LinearLayout with android:orientation="vertical" attribute. Like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".fragment.MeActivity">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/me_bg2"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/fake_head"
android:layout_centerHorizontal="true"
android:layout_marginTop="40dp"
android:id="#+id/iv_fake_head"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#id/iv_fake_head"
android:text="--"
android:textSize="22dp"
android:textColor="#ffffff"
android:layout_marginTop="15dp"
android:id="#+id/tv_name"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#id/tv_name"
android:text="积分"
android:textColor="#ffffff"
android:layout_marginTop="15dp"
android:textSize="20dp"
android:background="#drawable/me_points_bg"
android:id="#+id/tv_points"
/>
</RelativeLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/lv_histories"
android:layout_gravity="bottom" />
</LinearLayout>
