My RecyclerView doesn't show any value in alert dialog. I am confused and don't know where should I looking for a problem in my code. I hope some of you guys met with same issue.
This is activity where I am calling my RecycleView andl AlertDialog.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pondeljak = (Button) findViewById(R.id.buttonPonedeljak);
utorak = (Button) findViewById(R.id.buttonUtorak);
sreda = (Button) findViewById(R.id.buttonSreda);
cetvrtak = (Button) findViewById(R.id.buttonCetvrtak);
petak = (Button) findViewById(R.id.buttonPetak);
db = new DataDays(this);
View view = getLayoutInflater().inflate(R.layout.casovi,null);
alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setView(view);
alertDialog = alertDialogBuilder.create();
recyclerView = (RecyclerView) view.findViewById(R.id.recycleCasoviID);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
casoviList = new ArrayList<>();
casoviItems = new ArrayList<>();
// for (Casovi c: casoviList){
Casovi casovi = new Casovi();
//casovi.setId(0);
casovi.setDan("asas");
casovi.setRedniBrCasa("ssss");
casovi.setNzaivCasa("ssddff");
casoviItems.add(casovi);
recycleViewAdapter = new RecycleViewAdapter(this, casoviItems);
recyclerView.setAdapter(recycleViewAdapter);
recycleViewAdapter.notifyDataSetChanged();
pondeljak.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (db.casoviCountPondeljak() == 0){
Intent intent = new Intent(MainActivity.this, Unos_casova.class);
intent.putExtra("Dan", "Pondeljak");
startActivity(intent);
}else {
alertDialog.show();
}
This is RecycleView class. I am not sure, maybe here is some problem?
public class RecycleViewAdapter extends RecyclerView.Adapter<RecycleViewAdapter.ViewHolder> {
private Context context;
private List<Casovi> casoviItems;
public RecycleViewAdapter(Context context, List<Casovi> casoviItems) {
this.context = context;
this.casoviItems = casoviItems;
}
#Override
public RecycleViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.prikaz_casova, parent,false);
return new ViewHolder(view, context);
}
#Override
public void onBindViewHolder( RecycleViewAdapter.ViewHolder holder, int position) {
Casovi casovi = new Casovi();
holder.redniBrCasPrikaz.setText(casovi.getRedniBrCasa());
holder.nazivCasPrikaz.setText(casovi.getRedniBrCasa());
}
#Override
public int getItemCount() {
return casoviItems.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView redniBrCasPrikaz;
public TextView nazivCasPrikaz;
public Button delteBtn;
public Button editBtn;
public CardView cardView;
public ViewHolder(View view, Context ctx) {
super(view);
context = ctx;
redniBrCasPrikaz = (TextView) view.findViewById(R.id.rednibrojCasaID);
nazivCasPrikaz = (TextView) view.findViewById(R.id.nazivcasaID);
delteBtn = (Button) view.findViewById(R.id.obrisiCasBtnID);
editBtn = (Button) view.findViewById(R.id.izmeniCasBtnID);
cardView = (CardView) view.findViewById(R.id.carViewID);
}
}
Layout casovi. That RecycleView on witch prikaz casova should be attached.

Here the error you made, in your RecyclerView Adapter class.
#Override
public void onBindViewHolder( RecycleViewAdapter.ViewHolder holder, int position) {
Casovi casovi = new Casovi();
It should be
Casovi casovi = casoviItems.get(position);
holder.redniBrCasPrikaz.setText(casovi.getRedniBrCasa());
holder.nazivCasPrikaz.setText(casovi.getRedniBrCasa());
}
You are all done

I'm creating a shopping list similar to listonic app, but I'm stuck in listView, the button inside my listView does not read clicks but OnItemClickListener is working well. the objective is the user can save multiple shopping list for example grocery list, self-care list, etc. I have searched everywhere but did not find something that works.
here is the activity for the shopping list
private ArrayList<String> data = new ArrayList<String>();
private FloatingActionButton addList;

Your MyListAdapter works as it should except int position should be final int position because button calls it from inner class.
The problem is that you are not using MyListAdapter. So change
mAdapter = new ArrayAdapter<String>(this, R.layout.list_wrapper_item, R.id.list_item_text, taskList);
To
mAdapter = new MyListAdapter(this, R.layout.list_wrapper_item, taskList);

I have an android app where I have used RecyclerView that shows a list of contacts. Now what I want is that when selecting the contacts, call the indicated number.
For now all it do is show the contacts, but when i click on it it calls, it does not do any action. I do not know how to get it to mark
I tried with onClick() and with button item.But Unsuccessful
My code:
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.MyViewHolder> {
private static final String TAG = "RecyclerViewAdapter";
Context mContext;
List<Contact> mData;
Dialog myDialog;
Button button;
public RecyclerViewAdapter(Context mContext, List<Contact> mData) {
this.mContext = mContext;
this.mData = mData;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v ;
v = LayoutInflater.from(mContext).inflate(R.layout.single_item_contact,parent,false);
final MyViewHolder vHolder = new MyViewHolder(v);
// Dialog ini
myDialog = new Dialog(mContext);
myDialog.setContentView(R.layout.dialog_contact);
myDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
vHolder.item_contact.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Toast.makeText(mContext,"Text Click item : "+String.valueOf(vHolder.getAdapterPosition()),Toast.LENGTH_SHORT).show();
TextView dialog_name_tv = (TextView) myDialog.findViewById(R.id.dialog_name_id);
TextView dialog_phone_tv = (TextView) myDialog.findViewById(R.id.dialog_phone_id);
ImageView dialog_contact_img = (ImageView)myDialog.findViewById(R.id.dialog_img);

You need to put setOnClickListener() into OnBindViewHolder().So far what i understand is you have Recycler View in which on item click you want to open a dialog box dialog_contact and this dialog box contains Contact information. After opening this dialog you want to call that person by clicking call button present in dialog.
#Override
public void onBindViewHolder(MyViewHolder holder, final int position) {
holder.tv_name.setText(mData.get(position).getName());
holder.tv_phone.setText(mData.get(position).getPhone());
holder.img.setImageResource(mData.get(position).getPhoto());
holder.item_contact.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
myDialog = new Dialog(mContext);
myDialog.setContentView(R.layout.dialog_contact);
myDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
myDialog.show();
TextView dialog_name_tv = (TextView)myDialog.findViewById(R.id.dialog_name_id);
Button dialog_btn_call= (Button )myDialog.findViewById(R.id.dialog_btn_call);
TextView dialog_phone_tv = (TextView) myDialog.findViewById(R.id.dialog_phone_id);
ImageView dialog_contact_img = (ImageView)myDialog.findViewById(R.id.dialog_img);
dialog_name_tv.setText(mData.get(vHolder.getAdapterPosition()).getName());
dialog_phone_tv.setText(mData.get(vHolder.getAdapterPosition()).getPhone());
dialog_contact_img.setImageResource(mData.get(vHolder.getAdapterPosition()).getPhoto());
dialog_btn_call.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//Do your code here
myDialog.dismiss();
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:" +mData.get(holder.getAdapterPosition()).getPhone()));
mContext.startActivity(intent);
}
});
}
});
}
Edit:-
I am searching for a long time on net. But no use. Please help or try to give some ideas how to solve this problem.

You need to change the height of cardview and linearlayout to wrap_content
<android.support.v7.widget.CardView
android:id="#+id/cardview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="6dp"
android:padding="6dp"
app:cardBackgroundColor="#ffdddddd"
app:cardCornerRadius="28dp"
app:cardElevation="6dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
I'm trying to adapt a recyclerview to display a list of objects. But actually I have some kind of wierd bug. My object have ID and Name data to display, but in the list, at first, I only can see the Id, and when I scroll down, only the rows going completely out of the screen are completely displayed...
This is my ListPresentActivity.
public class ListPresentActivity extends AppCompatActivity implements ViewInterface {
private static final String EXTRA_PRESENT_ID = "EXTRA_PRESENT_ID";
private static final String EXTRA_PRESENT_NAME = "EXTRA_PRESENT_NAME";
private List<PresentItem> listOfPresent;
private LayoutInflater layoutInflater;
private RecyclerView recyclerView;
private CustomAdapter adapter;
private PresentController presentController;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_present);
recyclerView = (RecyclerView) findViewById(R.id.rec_list_activity);
recyclerView.setHasFixedSize(true);
layoutInflater = getLayoutInflater();
presentController = new PresentController(this, new FakePresentModel());
}
#Override
public void startDetailActivity(int id, String name, String info, String target, String advice, String price) {
//public void startDetailActivity(int id) {
Intent i = new Intent(this,PresentDetailActivity.class);
i.putExtra(EXTRA_PRESENT_ID, id);
i.putExtra(EXTRA_PRESENT_NAME, name);
startActivity(i);
}
#Override
public void setUpAdapterAndView(List<PresentItem> listOfPresent) {
this.listOfPresent = listOfPresent;
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
adapter = new CustomAdapter();
recyclerView.setAdapter(adapter);
}
private class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.CustomViewHolder>{
#Override
public CustomAdapter.CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = layoutInflater.inflate(R.layout.item_present, parent, false);
return new CustomViewHolder(v);
}
#Override
public void onBindViewHolder(CustomAdapter.CustomViewHolder holder, int position) {
PresentItem currentPresent = listOfPresent.get(position);
holder.id.setText(
Integer.toString(currentPresent.getId())
);
holder.name.setText(
currentPresent.getName()
);
}
#Override
public int getItemCount() {
return listOfPresent.size();
}
class CustomViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
private TextView id;
private TextView name;
private ViewGroup container;
public CustomViewHolder(View itemView){
super(itemView);
this.id = (TextView) itemView.findViewById(R.id.texv_item_id);
this.name = (TextView) itemView.findViewById(R.id.texv_item_name);
this.container = (ViewGroup) itemView.findViewById(R.id.root_list_present);
this.container.setOnClickListener(this);
}
#Override
public void onClick(View v) {
PresentItem presentItem = listOfPresent.get(
this.getAdapterPosition()
);
presentController.onListItemClick(presentItem);
}
}
}
}
The layout item_present.xml
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="88dp"
android:id="#+id/root_list_present"
xmlns:tools="http://schemas.android.com/tools">
<TextView
android:id="#+id/texv_item_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:textSize="48sp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:text="#id" />
<TextView
android:id="#+id/texv_item_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="84dp"
android:layout_marginTop="8dp"
android:ellipsize="end"
android:maxLines="1"
android:textSize="20sp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:text="collier" />
</android.support.constraint.ConstraintLayout>
And my list layout
<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"
tools:context="net.lubbee.bruh.view.ListPresentActivity">
<android.support.v7.widget.RecyclerView
android:id="#+id/rec_list_activity"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.support.constraint.ConstraintLayout>
I have search for a long time now, and the only concording result I have fount seems to be fixed with the recyclerView.setHasFixedSize(true); which is not my case...
Thanks for your time!
PS : If there is some code parts needed missing, just say the word! :]
Just after the first loading.
After one scroll to the bottom and back to the top of the screen
<LinearLayout android:layout_width="match_parent"
android:layout_height="88dp"
android:weightSum="1"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_gravity="center_vertical"
android:layout_weight="0.2"
android:layout_width="0dp"
android:layout_height="wrap_content" />
<TextView
android:layout_gravity="center_vertical"
android:layout_weight="0.8"
android:layout_width="0dp"
android:layout_height="wrap_content" />
</LinearLayout>
Try this simple LinearLayout it should work
You can also add other properties, but for now try it out
