ListView onItemClick "unfortunately myapp has stopped" error android

ListView onItemClick "unfortunately myapp has stopped" error android - java

I used ListView on my layout but on ItemClick event it shows this error : "unfortunately myappname has stopped"
this is my java code booking.java the OnCreate method :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.booking);
lv = (ListView) findViewById(R.id.list);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(getApplicationContext(), "Hello " + i, Toast.LENGTH_SHORT).show();
}
});
}
And my layout

Can anyone please help me to solve this problem ?

Try this
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String item = ((TextView)view).getText().toString();
Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show();
}
});

Try setOnItemSelectedListener instead of onItemClickedListener.

RecyclerView only lists first item despite layout changes

I understand this might be a duplicate, but every other solution here didn't work in my case, such as changing the layout_height to wrap_content instead of match_parent.
My Firestore database has 2 values stored inside an array, and I want to display both of them (more in the future) in my RecyclerView, however, it only displays the first value, at position 0.
Here is my Activity where the Recycler and the Adapter are created:
ActivityOs
private FirestoreAdapter listAdapter;
private FirebaseFirestore db = FirebaseFirestore.getInstance();
private CollectionReference osRef = db.collection("cliente");
private DocumentReference docRef = osRef.document("clienteTeste");
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_os);
RecyclerView recyclerView = findViewById(R.id.recyclerViewOs);
/*docRef.get().addOnCompleteListener(task -> {
if (task.isSuccessful()) {
DocumentSnapshot document = task.getResult();
if (document.exists()) {
Log.e("RESULTADO","result:" + document.toString());
}
}
});*/
Query query = osRef.orderBy("serviceOrder",
Query.Direction.ASCENDING);
FirestoreRecyclerOptions<ServiceDocument> options =
new FirestoreRecyclerOptions.Builder<ServiceDocument>()
.setQuery(osRef, ServiceDocument.class)
.build();
listAdapter = new FirestoreAdapter(options);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(listAdapter);
listAdapter.notifyDataSetChanged();
}
#Override
protected void onStart() {
super.onStart();
listAdapter.startListening();
}
#Override
protected void onStop() {
super.onStop();
listAdapter.stopListening();
}
The commented code shows me that the database does indeed return the 2 values stored in it.
Here is my Adapter class:
public class FirestoreAdapter extends FirestoreRecyclerAdapter<ServiceDocument, FirestoreAdapter.ViewHolder> {
public FirestoreAdapter(#NonNull FirestoreRecyclerOptions<ServiceDocument> options) {
super(options);
}
#Override
protected void onBindViewHolder(#NonNull ViewHolder holder, int position, #NonNull ServiceDocument model) {
holder.osIdItem.setText(String.valueOf(model.serviceOrderArray.get(position).getId()));
holder.osClientItem.setText(model.serviceOrderArray.get(position).getClient().getName());
holder.osDateItem.setText(model.serviceOrderArray.get(position).getDate());
holder.osValueItem.setText(String.valueOf(model.serviceOrderArray.get(position).getTotalValue()));
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
View view = layoutInflater.inflate(R.layout.layout_os_item, parent, false);
return new FirestoreAdapter.ViewHolder(view);
}
public class ViewHolder extends RecyclerView.ViewHolder {
private TextView osIdItem;
private TextView osClientItem;
private TextView osDateItem;
private TextView osValueItem;
public ViewHolder(View itemView) {
super(itemView);
osIdItem = itemView.findViewById(R.id.osIDItem);
osClientItem = itemView.findViewById(R.id.osClientNameItem);
osDateItem = itemView.findViewById(R.id.osDateItem);
osValueItem = itemView.findViewById(R.id.osValueItem);
}
}
}
And here are my layouts, activity_os.xml where my RecyclerView is created, and layout_os_item.xml where the layouts for each item of the recycler are made.

Using a Floating Action Button with ListView in a Fragment with Navigation

I am new to using Java and Android Studio and I'm stumped. I have created an application with bottom navigation and that functions fine. I'm trying to use a floating action button to create list entries into a ListView. I've created an adapter for the ListView and an XML for it but when I actually click on the tab, nothing shows up. I think the issue may lie in using onCreate vs. onCreateView, but since I'm new I'm not really sure what I should put where. As my code stands, the fragment loads with nothing showing except for the title of the fragment. I stopped using onCreateView and put everything under onCreate because my fragment was crashing. Any help would be appreciated.
Fragment Java:
public class DashboardFragment extends Fragment {
private DashboardViewModel dashboardViewModel;
private FragmentDashboardBinding binding;
ArrayList<String> listItems = new ArrayList<String>();
ArrayAdapter<String> adapter;
ListView ListView;
EditText editText;
public String test;
public void onCreate(#NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
editText = (EditText) getView().findViewById(R.id.editText);
listItems = new ArrayList<String>();
listItems.add("Let's see where this ends up");
ListView = (ListView) getView().findViewById(R.id.ListView);
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, listItems);
ListView.setAdapter(adapter);
binding.fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.fab:
listItems.add(editText.getText().toString());
adapter.notifyDataSetChanged();
}
}
}
);
ListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(getActivity(), "Clicked", Toast.LENGTH_SHORT)
.show();
}
});
dashboardViewModel = new ViewModelProvider(this).get(DashboardViewModel.class);
binding = FragmentDashboardBinding.inflate(inflater, container, false);
View root = binding.getRoot();
final TextView textView = binding.textDashboard;
dashboardViewModel.getText().observe(getViewLifecycleOwner(), new Observer<String>() {
#Override
public void onChanged(#Nullable String s) {
textView.setText(s);
}
});
}
#Override

I want to remove the blank space which occurs while visibility is set to GONE, as shown in the snapshot below.
Image of empty space on removing top card
Image before setting visibility GONE

Simply remove the object from the list if its user is not equal to AuthUserEmail and notify your adapter.
NO NEED TO MAKE VISBILITY GONE OF THE HOLDER VIEW

Your RecyclerView takes space even if visibility is set to gone. It still takes space because there are items that RecyclerView wants to display. Although you can fix this by removing the items RecyclerView wants to show. It would take a lot of memory if you want show that RecyclerView again because you still have to add the items back. What I would recommend is to wrap your RecyclerView with a layout eg. LinearLayout and set that layout's visibility to gone.
Try doing this:
<LinearLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Place your RecyclerView here -->
<!-- change visibility of container view -->
</LinearLayout>
*Edit: You didn't explain it well. I get what you want now. You simply have to remove the item from your RecyclerView list. The best way to do this is by using DiffUtil. This a great tutorial online showing how you can implement it in Java. https://codinginflow.com/tutorials/android/room-viewmodel-livedata-recyclerview-mvvm/part-1-introduction

Cover your RecyclerView with a FrameLayout and then set your visibility over there.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recycleView"
android:layout_gravity="top"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout_editor_absoluteX="1dp"
tools:layout_editor_absoluteY="1dp" />
</FrameLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
If this doesnt works then:
Cover your Cardview which is the layout that you designed for your Recyclerview with a FrameLayout. Anyone of them will surely work out for you.

Android: ListView "setOnItemSelectedListener" not working

I have a ListView (of a predefined set of quotes in a string array) in my android program that does not seem to work when an item is selected. The ListView is populated, but the toast message in my onClickListener is never called. I am not sure what the issue is here. I have never run into this problem before.
Here is my onCreate method
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView)findViewById(R.id.listView);
List<String> quotesList = new ArrayList<String>(Arrays.asList(quotes));
ArrayAdapter arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, quotesList);
listView.setAdapter(arrayAdapter);
listView.setOnItemSelectedListener(new ListView.OnItemSelectedListener(){
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
Toast.makeText(getApplicationContext(), "Toast", Toast.LENGTH_SHORT).show();
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {}
});
}
Here is my activity_main.xml
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#b2cfff"
tools:context="com.examples.myteststuff.listviews.MainActivity">
<LinearLayout
android:layout_width="368dp"
android:layout_height="495dp"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:orientation="vertical"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:src="#drawable/icon"
android:layout_height="wrap_content" />
<ListView
android:layout_width="match_parent"
android:id="#+id/listView"
android:background="#drawable/border"
android:layout_marginHorizontal="8dp"
android:layout_marginVertical="8dp"
android:layout_height="match_parent"/>
</LinearLayout>
</android.support.constraint.ConstraintLayout>

Try setOnItemClickListener instead :
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(getApplicationContext(), "Toast", Toast.LENGTH_SHORT).show();
}
});
Hope this helps

PopUp window with Spinner OnItem Selection Not Working

I was tried to implement the spinner inside the popupwindow, selection of spinner item with OnItemselection was not working, I have two kind of Experimental Test in this scenario.
Experimental Test-1 I've implemented the OnItemSelectionListener,result of experiment test-1 is
java.lang.NullPointerException: Attempt to invoke virtual method 'void
android.widget.Button.setOnClickListener(android.view.View$OnClickListener)'
on a null object reference.
Experimental Test-2 use getSelectedItem() method to get the position, result of only first position value showing in Toast.
Here is my code,
Java Code Implementation
private void DialogTest(){
String[] Title = {"Select Title","Teacher","Employer","Lecturer","Coach","Mentor","Co-Worker","Prinicpal","Dean","Other"};
LayoutInflater layoutInflater =(LayoutInflater)getActivity().getBaseContext().getSystemService(getActivity().LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.dialog_test, null);
final PopupWindow popupWindow = new PopupWindow(popupView, isPortrait ? getHeightByPercentage(50) : getWidthByPercentage(50), LinearLayout.LayoutParams.WRAP_CONTENT);
Spinner popupSpinner = (Spinner)popupView.findViewById(R.id.popupspinner);
Button button_test_cancel =(Button)popupView.findViewById(R.id.button_test_cancel);
Button button_test_send =(Button)popupView.findViewById(R.id.button_test_send);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_item, Title);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
popupSpinner.setAdapter(adapter);
popupWindow.showAsDropDown(btn_request_testimonial, 50, -30);
//Step-1 Experimental Test
popupSpinner.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
int selectedPosition = position;
Toast.makeText(getActivity().getBaseContext(),selectedPosition, Toast.LENGTH_LONG).show();
}
});
//Step-2 Experimental Test
final String categoryTitle = popupSpinner.getSelectedItem().toString();
Toast.makeText(getActivity().getBaseContext(),categoryTitle, Toast.LENGTH_LONG).show();
button_test_send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
button_test_cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
popupWindow.setOutsideTouchable(true);
popupWindow.setFocusable(true);

You are setting onClickListener to spinner thus it's being clicked by the first item. Rater you should use onItemSelectedListener
//Step-1 Experimental Test
popupSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
Toast.makeText(SolveTest.this, String.valueOf(position), Toast.LENGTH_LONG).show();
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});

try this one
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
Object item = arg0.getItemAtPosition(arg2);
if (item!=null) {
Toast.makeText(MainActivity.this, item.toString(),
Toast.LENGTH_SHORT).show();
}
Toast.makeText(MainActivity.this, "Selected",
Toast.LENGTH_SHORT).show();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

ListView onItemClick "unfortunately myapp has stopped" error android - java

Try this listView1.setOnItemClickListener(new OnItemClickListener() { #Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { String item = ((TextView)view).getText().toString(); Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show(); } });

Try setOnItemSelectedListener instead of onItemClickedListener.
