I'm really struggling with this, what I need is when the user clicks on the recipe image, which comes from the ArrayList listRecipe put into the RecyclerView, the value from myTextView1 should be passed to the CreateMealPlan activity so it can be saved along with the date to an SQLite database.
Hope I've made this clear, thanks in advance for any help.

RecyclerAdapter
public class RecipeListAdapter extends RecyclerView.Adapter<com.stu54259.plan2cook.Adapters.RecipeListAdapter.ViewHolder> {
private List<Category> listRecipe;
private LayoutInflater mInflater;
private com.stu54259.plan2cook.Adapters.RecipeListAdapter.ItemClickListener mClickListener;
// data is passed into the constructor
public RecipeListAdapter(Context context, List<Category> data) {
this.mInflater = LayoutInflater.from(context);

}
// inflates the row layout from xml when needed
#Override
public com.stu54259.plan2cook.Adapters.RecipeListAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = mInflater.inflate(R.layout.cardview_recipe, parent, false);
return new com.stu54259.plan2cook.Adapters.RecipeListAdapter.ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull com.stu54259.plan2cook.Adapters.RecipeListAdapter.ViewHolder holder, int position) {
holder.myTextView1.setText(listRecipe.get(position).getRecipe_name());
holder.myTextView2.setText(listRecipe.get(position).getCategory_name());
String image2 = listRecipe.get(position).getImage2();
Bitmap myBitmap = BitmapFactory.decodeFile(image2);
if (myBitmap != null)

else
holder.imgImage.setImageResource(listRecipe.get(position).getImage());
}
// total number of rows
#Override
public int getItemCount() {
return listRecipe.size();
}
// stores and recycles views as they are scrolled off screen
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView myTextView1;
TextView myTextView2;
ImageView imgImage;
ViewHolder(View itemView) {
super(itemView);
myTextView1 = itemView.findViewById(R.id.txtName);
myTextView2 = itemView.findViewById(R.id.txtCategory);
imgImage = itemView.findViewById(R.id.imgImage);
myTextView1.setOnClickListener(this);
myTextView1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String recipe_name = myTextView1.getText().toString();
}
});
}
/**
* Called when a view has been clicked.
*
* #param v The view that was clicked.
*/
#Override
public void onClick(View v) {
}
}
// allows clicks events to be caught
void setClickListener(com.stu54259.plan2cook.Adapters.RecipeListAdapter.ItemClickListener itemClickListener) {
this.mClickListener = itemClickListener;
}
// parent activity will implement this method to respond to click events
public interface ItemClickListener {
void onItemClick(View view, int position);
}
}
You should:
Define an interface that will be used to handle click events (similar to your ItemClickListener);
Implement this interface as an anonymous class or by extending your Activity;
Pass that instance of the new interface to your adapter;
Set click listener, handle click events and pass data back into your Activity.
Step 1: define an interface
Sample interface:
interface OnRecipeClickListener {
void onRecipeClicked(int position, String someString);
}
Step 2: implement the interface
This part is located inside of your Activity class:
new OnRecipeClickListener() {
public void onRecipeClicked(int position, String someString) {
Log.d(CreateMealPlan.class.getSimpleName(), "Here is the data: " + someString);
}
}
Step 3: passing this interface to the adapter
public class RecipeListAdapter extends RecyclerView.Adapter<com.stu54259.plan2cook.Adapters.RecipeListAdapter.ViewHolder> {
...
private OnRecipeClickListener clickListener;
// data is passed into the constructor
public RecipeListAdapter(Context context, List<Category> data, OnRecipeClickListener clickListener) {
...
this.clickListener = clickListener;
}
...
}
Step 4: setting click listeners to view holders
public class RecipeListAdapter extends RecyclerView.Adapter<com.stu54259.plan2cook.Adapters.RecipeListAdapter.ViewHolder> {
...
#Override
public void onBindViewHolder(#NonNull com.stu54259.plan2cook.Adapters.RecipeListAdapter.ViewHolder holder, int position) {
...
holder.image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
clickListener.onRecipeClicked(position,
holder.textView1.getText().toString());
}
});
}
...
}
Code from Step 2 can be used like that:
OnRecipeClickListener listener = new OnRecipeClickListener() {
public void onRecipeClicked(int position, String someString) {
Log.d(CreateMealPlan.class.getSimpleName(), "Here is the data: " + someString);
}
};
adapterRecipe = new RecipeListAdapter(this, listRecipe, listener);

I have 2 recycler views that have cards.They basically look the same have the same number of cards and everthing. The first one is for like viewing and other stuff and the second one is only for deleting cards. OnlongClicking a card in the first recycler view triggers the opening of the second recycler view. I wanted to add transitions in between them like what keep notes has done when a card is long clicked. Both the recycler view use the same adapter. I have set what the adapter should do based on passing context to the adapter. enter image description here this is my 1st layout having the 1st recycler view.enter image description here this is the 2nd layout having the second recycler view.I want like a seamless transition for the tool bar again just like what Google keeps has done.A simple solution would be preferred as I am very new to this stuff.

I have added the code related to the scene transititon which is in the adapter.
here is a gif of the problem when i add a scene transition
enter image description here
As u can see there are 2 pauses when going from 1st to 2nd activity 1st pause being longer 2nd one shorter. And also a pause when exiting the 2nd activity which seems to have the same duration as the 2nd pause.
I want to create an onclick listener that reads the String from one TextView and then I somehow pass that string onto the main activity in order to open a third activity
So my main activity looks like this
public class AdvancedResults extends AppCompatActivity {
private RecyclerView mRecyclerView;
private AdvancedAdapter mAdapter;
private RecyclerView.LayoutManager mLayoutManager;
private ArrayList<String> mNames = new ArrayList<>();
private ArrayList<String> mImageUrls = new ArrayList<>();
private ArrayList<String> saved_recipes_with_ingredients = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_advanced_results);
advancedList.add(new AdvancedItem(R.drawable.ic_android, "test1", "test2");
advancedList.add(new AdvancedItem(R.drawable.ic_android, "test3", "test4");
mRecyclerView = findViewById(R.id.recyclerView1);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mAdapter = new AdvancedAdapter(advancedList);
mRecyclerView.setLayoutManager(mLayoutManager);
mRecyclerView.setAdapter(mAdapter);
mAdapter.setOnItemClickListener(new AdvancedAdapter.OnItemClickListener() {
#Override
public void onItemClick(int position) {
// I want to open a new activity and append the string from the TextView here (maybe with get/set)
}
});
}
And my recycler adapter looks like this
public class AdvancedAdapter extends RecyclerView.Adapter<AdvancedAdapter.AdvancedViewHolder> {
private ArrayList<AdvancedItem> mAdvancedList;
private OnItemClickListener mListener;
public interface OnItemClickListener {
void onItemClick(int position);
}
public void setOnItemClickListener(OnItemClickListener listener) {
mListener = listener;
}
public static class AdvancedViewHolder extends RecyclerView.ViewHolder {
public ImageView mImageView;
public TextView mTextView1;
public TextView mTextView2;
public AdvancedViewHolder(View itemView, final OnItemClickListener listener) {
super(itemView);
mImageView = itemView.findViewById(R.id.imageViewADV);
mTextView1 = itemView.findViewById(R.id.textViewADV1);
mTextView2 = itemView.findViewById(R.id.textViewADV2);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (listener != null) {
int position = getAdapterPosition();
//how do I get the string from the TextView and pass it onto the main class?
if (position != RecyclerView.NO_POSITION) {
listener.onItemClick(position);
}
}
}
});
}
}
public AdvancedAdapter(ArrayList<AdvancedItem> advancedList) {
mAdvancedList = advancedList;
}
#Override
public AdvancedViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.advanced_item, parent, false);
AdvancedViewHolder evh = new AdvancedViewHolder(v, mListener);
return evh;
}
#Override
public void onBindViewHolder(AdvancedViewHolder holder, int position) {
AdvancedItem currentItem = mAdvancedList.get(position);
holder.mImageView.setImageResource(currentItem.getImageResource());
holder.mTextView1.setText(currentItem.getText1());
holder.mTextView2.setText(currentItem.getText2());
}
#Override
public int getItemCount() {
return mAdvancedList.size();
}
i'm just not sure how im supposed to do that and what method to use.
So if you want the text from the text view you do:
String text = textViewId.getText();
But in your case you want to add the text for each one of the views on the list
So on the adapter how make a on click listener:
if (listener != null) {
int position = getAdapterPosition();
String text = mTextView1.getText();
Intent i = new Intent(getApplicationContext(), YourActitivity.class);
i.putExtra("nameYouWant", text)
startActivity(i);
if (position != RecyclerView.NO_POSITION) {
listener.onItemClick(position);
}
Now on your activity :
String text = intent.getStringExtra("nameYouWant");
You can use interface to pass the second String param. So just add one String param like this -
public interface OnItemClickListener {
void onItemClick(int position, String text);
}
And in adapter pass the string on click of the item along with the position
listener.onItemClick(position, mTextView1.getText().toString());
And in the activity, you will receive the String text, from there you can pass it to ThirdActivity via bundle.
mAdapter.setOnItemClickListener(new AdvancedAdapter.OnItemClickListener() {
#Override
public void onItemClick(int position, String textData) {
Intent i = new Intent(this, ThirdActivity.class);
i.putExtra("TEXT_KEY", textData);
}
});
Hope it will help!!
In MainActivity I have NavigationDrawer. For each menu item, I have a fragment class with a corresponding layout. One of them is MyCardFragment.java. In this fragment, I am showing CardView through RecyclerView.
My CardView contains some TextViews and an ImageView. What I wanted is when a user clicks a widget it will open a custom input dialog (contains a TextView, an EditText, a positive button, and a negative button) for updating data in Firebase Real-time database. I created a dialog fragment class, but don't know how to implement it in my adapter class.
This is my main activity which holds RecyclerView and CardView:
MainActivity.java:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAuth=FirebaseAuth.getInstance();
currentUser = mAuth.getCurrentUser();
if (currentUser != null){
myRef = FirebaseDatabase.getInstance().getReference().child("user").child(currentUser.getUid());
}
mContext = MainActivity.this;
mDrawerLayout = findViewById(R.id.drawer_layout);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ActionBar actionbar = getSupportActionBar();
actionbar.setDisplayHomeAsUpEnabled(true);
actionbar.setHomeAsUpIndicator(R.drawable.ic_action_name);
NavigationView navigationView = findViewById(R.id.nav_view);
//navigationView.inflateHeaderView(R.layout.nav_header);
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
// set item as selected to persist highlight
menuItem.setChecked(true);
// close drawer when item is tapped
mDrawerLayout.closeDrawers();
// Add code here to update the UI based on the item selected
// For example, swap UI fragments here
switch (menuItem.getItemId()) {
case R.id.nav_myCards:
menuItem.setChecked(true);
getSupportActionBar().setTitle("MY Cards");
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.content_frame,new MyCardFragment())
.commit();
break;
return true;
}
});
mDrawerLayout.addDrawerListener(
new DrawerLayout.DrawerListener() {
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
// Respond when the drawer's position changes
}
#Override
public void onDrawerOpened(View drawerView) {
// Respond when the drawer is opened
}
#Override
public void onDrawerClosed(View drawerView) {
// Respond when the drawer is closed
}
#Override
public void onDrawerStateChanged(int newState) {
// Respond when the drawer motion state changes
}
}
);
navigationView.getMenu().getItem(0).setChecked(true);
//Highlighted
//onNavigationItemSelected(navigationView.getMenu().getItem(0));
setupFirebaseAuth();
if (currentUser != null){
//updateNavHeader();
}
}
Custom Dialog Fragment:
DialogCompanyAddress.java:
public class DialogCompanyAddress extends DialogFragment {
public DialogCompanyAddress() {
// Required empty public constructor
}
#NonNull
#Override
public Dialog onCreateDialog(#Nullable Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.fragment_dialog_company_address,null));
builder.setPositiveButton("Save", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//save data to the firebase
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//Do
}
});
return builder.create();
}
}
finally the adapter:
RecyclerviewAdapter.java:
public class RecyclerviewAdapter extends RecyclerView.Adapter<RecyclerviewAdapter.MyHolder> {
// ... constructor and member variables
// Usually involves inflating a layout from XML and returning the holder
Context mContext;
List<Template> listdata;
public RecyclerviewAdapter(Context context,List<Template> listdata) {
this.mContext = context;
this.listdata = listdata;
}
#Override
public MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {
/*// Inflate the custom layout
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview,parent,false);
// Return a new holder instance
MyHolder myHolder = new MyHolder(view);
return myHolder;*/
View view = LayoutInflater.from(mContext).inflate(R.layout.cardview,parent,false);
return new MyHolder(view);
}
public void onBindViewHolder(MyHolder holder, int position) {
holder.pname.setText(listdata.get(position).getP_name());
holder.pdesignation.setText(listdata.get(position).getP_designation());
holder.pemail.setText(listdata.get(position).getP_email());
holder.pphone.setText(listdata.get(position).getP_phone());
holder.cname.setText(listdata.get(position).getC_name());
holder.caddress.setText(listdata.get(position).getC_address());
//holder.tempID.setText(listdata.get(position).getTempID());
Glide.with(mContext).load(listdata.get(position).getC_logo()).into(holder.logo_image);
}
#Override
public int getItemCount() {
//return listdata.size();
int arr = 0;
try{
if(listdata.size()==0) {
arr = 0;
} else {
arr=listdata.size();
}
} catch (Exception e){
e.printStackTrace();
}
return arr;
}
class MyHolder extends RecyclerView.ViewHolder{
// Your holder should contain a member variable
// for any view that will be set as you render a row
TextView pname,caddress,pemail,pdesignation,pphone,cname,tempID;
ImageView logo_image;
// We also create a constructor that accepts the entire item row
// and does the view lookups to find each subview
public MyHolder(final View itemView) {
// Stores the itemView in a public final member variable that can be used
// to access the context from any ViewHolder instance.
super(itemView);
pname = (TextView) itemView.findViewById(R.id.txt_personName);
caddress = (TextView) itemView.findViewById(R.id.txt_address);
pemail = (TextView) itemView.findViewById(R.id.txt_email);
pdesignation = (TextView) itemView.findViewById(R.id.txt_designation);
pphone = (TextView) itemView.findViewById(R.id.txt_phone);
cname = (TextView) itemView.findViewById(R.id.txt_companyName);
logo_image = itemView.findViewById(R.id.imageView);
tempID = itemView.findViewById(R.id.tempID);
caddress.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(mContext,"Clicked on Address",Toast.LENGTH_SHORT).show();
DialogCompanyAddress address = new DialogCompanyAddress();
//address.show(getSupportFragmentManager);--->This line give me error
}
});
}
}
use a interface in your adapter like below
public class RecyclerviewAdapter extends RecyclerView.Adapter<RecyclerviewAdapter.MyHolder> {
public interface ClickListner {
void IconClick(Template template);
}
Context mContext;
List<Template> listdata;
private final ClickListner listner;
public RecyclerviewAdapter(Context context, List<Template> listdata, ClickListner listner) {
this.mContext = context;
this.listdata = listdata;
this.listner = listner;
}
#Override
public MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(mContext).inflate(R.layout.cardview, parent, false);
return new MyHolder(view);
}
public void onBindViewHolder(MyHolder holder, int position) {
holder.pname.setText(listdata.get(position).getP_name());
holder.pdesignation.setText(listdata.get(position).getP_designation());
holder.pemail.setText(listdata.get(position).getP_email());
holder.pphone.setText(listdata.get(position).getP_phone());
holder.cname.setText(listdata.get(position).getC_name());
holder.caddress.setText(listdata.get(position).getC_address());
//holder.tempID.setText(listdata.get(position).getTempID());
Glide.with(mContext).load(listdata.get(position).getC_logo()).into(holder.logo_image);
holder.bind(listdata.get(position), listner);
}
#Override
public int getItemCount() {
//return listdata.size();
int arr = 0;
try {
if (listdata.size() == 0) {
arr = 0;
} else {
arr = listdata.size();
}
} catch (Exception e) {
e.printStackTrace();
}
return arr;
}
class MyHolder extends RecyclerView.ViewHolder {
TextView pname, caddress, pemail, pdesignation, pphone, cname, tempID;
ImageView logo_image;
public MyHolder(final View itemView) {
super(itemView);
pname = (TextView) itemView.findViewById(R.id.txt_personName);
caddress = (TextView) itemView.findViewById(R.id.txt_address);
pemail = (TextView) itemView.findViewById(R.id.txt_email);
pdesignation = (TextView) itemView.findViewById(R.id.txt_designation);
pphone = (TextView) itemView.findViewById(R.id.txt_phone);
cname = (TextView) itemView.findViewById(R.id.txt_companyName);
logo_image = itemView.findViewById(R.id.imageView);
tempID = itemView.findViewById(R.id.tempID);
// caddress.setOnClickListener(new View.OnClickListener() {
// #Override
// public void onClick(View v) {
// //Toast.makeText(mContext,"Clicked on
Address",Toast.LENGTH_SHORT).show();
// DialogCompanyAddress address = new DialogCompanyAddress();
// //address.show(getSupportFragmentManager);--->This line give me
error
//
// }
// });
}
public void bind(final Template template, final ClickListner Listner) {
// DeleteIcon.setOnClickListener(new View.OnClickListener() {
// #Override
// public void onClick(View v) {
// delListner.onDeleteIconClick(card, position);
// }
// });
caddress.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Listner.IconClick(template);
}
});
}
}
and in your fragment you need to initialize the adapter. when initialize you can override the ClickListner interface.
i created a recyclerview where i can see all my chats. Every item contains the name, the lastmessage and a thumb. if the user send or receive a new message, it should be displayed there and the item should go to position 0. Now i have the problem that the message is displayed, but the chat item goes only to the first position if the position was not 0 before. So if i receive two new messages its not working anymore because the data model is the same like before. So how can i fit my data model to the current position of every item. Currently my adapter looks like this:
private static final String TAG = "CustomAdapter";
private Context context;
private Activity mActivity;
private List<MatchesObject> matchesList;
private String currentUid;
public matchadapterino(Activity mActivity, ArrayList<MatchesObject> mDataSet) {
this.mActivity = mActivity;
this.matchesList = mDataSet;
}
// Create new views (invoked by the layout manager)
#Override
public matchadapterino.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
// Create a new view.
View v = LayoutInflater.from(viewGroup.getContext())
.inflate(R.layout.matchesitem, viewGroup, false);
return new matchadapterino.ViewHolder(v);
}
// Replace the contents of a view (invoked by the layout manager)
#Override
public void onBindViewHolder(final matchadapterino.ViewHolder viewHolder, final int position) {
viewHolder.getMatchname().setText(matchesList.get(position).getUsername());
if (!matchesList.get(position).getProfileImageUrl().equals("default")) {
Picasso.with(mActivity).load(matchesList.get(position).getProfileImageUrl()).into(viewHolder.getMatchImage());
getLastMSG(matchesList.get(position).getUserId(), viewHolder.getLastMSG(), position);
viewHolder.getMatchImage().setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(mActivity, UserDetailView.class);
//
i.putExtra("userId", matchesList.get(position).getUserId());
mActivity.startActivity(i);
}
});
} else {
viewHolder.getMatchImage().setImageResource(R.mipmap.ic_launcher_round);
}
viewHolder.getForeground().setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(mActivity, Chat.class);
Bundle b = new Bundle();
b.putString("matchId", matchesList.get(position).getUserId());
i.putExtras(b);
mActivity.startActivity(i);
}
});
}
#Override
public int getItemCount() {
return matchesList.size();
}
// Get element from your dataset at this position and replace the contents of the view
// with that element
public void removeItem(int position) {
matchesList.remove(matchesList.get(position));
notifyItemRemoved(position);
}
// Return the size of your dataset (invoked by the layout manager)
