How to set up custom input dialog for saving data in Firebase when user clicks any textview widget in cardview?

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.

Passing results (serializable class) from DialogFragment to Fragment

I have main activity which contains fragments. One of the fragment is calling dialogFragment for new item entry. This new item is specified by Serializable class.
Just to be more specific:
item.java
public class Item implements Serializable {
private String mTitle;
private String mDescription;
private Boolean mTrue;
//getters and setters
public String getTitle() {
return mTitle;
}
public void setTitle(String mTitle) {
this.mTitle = mTitle;
}
public String getDescription() {
return mDescription;
}
public void setDescription(String mDescription) {
this.mDescription = mDescription;
}
public Boolean isTrue() {
return mTrue;
}
public void setTrue(Boolean mTrue) {
this.mTrue = mTrue;
}
}
DialogNewItem
public class DialogNewItem extends DialogFragment {
//filters state holder
Boolean isTrue = false;
//filters state end
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState){
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View dialogView = inflater.inflate(R.layout.new_item, null);
final EditText editTitle = (EditText) dialogView.findViewById(R.id.editTitle);
final EditText editDescription = (EditText) dialogView.findViewById(R.id.editDescription)
//filter icons
final ImageView ivIsTrue = (ImageView) dialogView.findViewById(R.id.filterTrue);
//filter icons end
//onClickListener for filter icons
ivIsTrue.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
if (isTrue == false) {
ivIsTrue.setBackgroundResource(R.drawable.border_white);
ivIsTrue.setImageResource(R.drawable.true_white);
isTrue = true;
} else {
ivIsTrue.setBackgroundResource(R.drawable.border_green);
ivIsTrue.setImageResource(R.drawable.true_green);
isTrue = false;
}
}
});
Button btnCancel = (Button) dialogView.findViewById(R.id.btnCancel);
Button btnOK = (Button) dialogView.findViewById(R.id.btnOK);
builder.setView(dialogView);
//cancel button
btnCancel.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
dismiss();
}
});
//give button
btnOK.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//new item
final Item newItem = new Item();
//Set its variables to match the users entries on the form
newItem.setTitle(editTitle.getText().toString());
newItem.setDescription(editDescription.getText().toString());
newItem.setTrue(isTrue);
dismiss();
}
});
return builder.create();
}
}
Now, I want to pass newItem from DialogNewItem (btnOK) to a listView Fragment. In other words I want to make a listView Fragment which will contain all the new items created in DialogNewItem.
I was trying different methods (set/getFragment, ArrayList, different interfaces, etc) but some how non of it works. I have no problem with passing newItem to listView in an activity:
//get the reference to dashboard
Dashboard callingActivity = (Dashboard) getActivity();
//pass new item back to dashboard
callingActivity.createNewItem(newItem);
and then dashboard activity:
public class Dashboard extends AppCompatActivity {
private ItemAdapter mItemAdapter;
public void createNewItem(Item n) {
mItemAdapter.addItem(n);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard);
mItemAdapter = new ItemAdapter();
ListView listItem = (ListView) findViewById(R.id.listView);
listItem.setAdapter(mItemAdapter);
}
//handle clicks on listView
listItem.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick (AdapterView<?> adapter, View view, int whichItem, long id ){
//creating temporary item which is reference to the clicked item
Item tempItem = mItemAdapter.getItem(whichItem);
//new dialog window
DialogShowItem dialog = new DialogShowItem();
//send reference to the item to be shown
dialog.sendItemSelected(tempItem);
//show the dialog window with the item
dialog.show(getFragmentManager(),"");
}
});
#Override
public View getView(int whichItem, View view, ViewGroup viewGroup){
//has been inflated already
if (view==null){
//creating layout inflater
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//instantiate view by inflating inflater (listItem layout)
view = inflater.inflate(R.layout.listitem, viewGroup, false);
}
Item tempItem = itemList.get(whichItem);
//grabbing the refrence to all variables
TextView txtTitle = (TextView) view.findViewById(R.id.txtTitle);
TextView txtDescription = (TextView) view.findViewById(R.id.txtDescription);
ImageView ivTrue = (ImageView) view.findViewById(R.id.imgSmTrue);
//setting text variables
txtTitle.setText(tempItem.getTitle());
txtDescription.setText(tempItem.getDescription());
//hide not relevant images
if (!tempItem.isTrue()){
ivTrue.setVisibility(View.INVISIBLE);
} else {ivTrue.setVisibility(View.VISIBLE);}
//category with different image src
return view;
}
and everything works perfectly, but when I want to do the same with Fragment instead of Activity, somehow I cannot make it work.
I would appreciate any help. Thanx
Fragment (with listview):
public class ListItems extends ListFragment {
private ItemAdapter mItemAdapter;
public void createNewItem(Item i) {
mItemAdapter.addItem(i);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstatceState) {
View view = inflater.inflate(R.layout.list_items, container, false);
//Item adapter
mItemAdapter = new ItemAdapter();
final ListView listItems = (ListView) view.findViewById(R.id.listView);
listItems.setAdapter(mItemAdapter);
//floating give button
FloatingActionButton fab = (FloatingActionButton) view.findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
DialogNewItem dialog = new DialogNewItem();
dialog.show(getFragmentManager(), "");
}
});
//handle clicks on itemList
listItems.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int whichItem, long id) {
Item tempItem = mItemAdapter.getItem(whichItem);
DialogShowItem dialog = new DialogShowItem();
dialog.sendItemSelected(tempItem);
dialog.show(getFragmentManager(), "");
}
});
return view;
}
#Override
protected void onPause() {
super.onPause();
mItemAdapter.saveItems();
}
public class ItemAdapter extends BaseAdapter {
List<Item> itemList = new ArrayList<Item>();
private JSONSerializer mSerializer;
public ItemAdapter() {
mSerializer = new JSONSerializer("myProject.json", getActivity().getApplicationContext());
try {
itemList = mSerializer.load();
} catch (Exception e) {
itemList = new ArrayList<Item>();
Log.e("Error loading items: ", "", e);
}
}
public void saveItems() {
try {
mSerializer.save(itemList);
} catch (Exception e) {
Log.e("Error saving items: ", "", e);
}
}
#Override
public int getCount() {
return itemList.size();
}
#Override
public Item getItem(int whichItem) {
return itemList.get(whichItem);
}
#Override
public long getItemId(int whichItem) {
return whichItem;
}
public void addItem(Item n) {
itemList.add(n);
notifyDataSetChanged();
}
#Override
public View getView(int whichItem, View view, ViewGroup viewGroup) {
if (view==null) {
LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.list_items, viewGroup, false);
}
Item tempItem = itemList.get(whichItem);
TextView txtTitle = (TextView) view.findViewById(R.id.txtTitle);
TextView txtDescription = (TextView) view.findViewById(R.id.txtDescription);
ImageView ivTrue = (ImageView) view.findViewById(R.id.imgSmTrue);
//setting text variables
txtTitle.setText(tempItem.getTitle());
txtDescription.setText(tempItem.getDescription());
//hide irrelevant images
if (!tempItem.isTrue()){
ivTrue.setVisibility(View.INVISIBLE);
} else {ivTrue.setVisibility(View.VISIBLE);}
return view;
}
}
}
It's a drawer activity so I'm showing it after drawer item click:
private void switchFragment(int position) {
Fragment fragment = null;
String fragmentID = "";
switch (position) {
case 0:
fragmentID = "LISTITEMS";
fragment = new ListItems();
break;
case 1:
fragmentID = "PROFILE";
fragment = new Profile();
break;
default:
break;
}
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragmentHolder, fragment, fragmentID).commit();
//close the drawer
mDrawerLayout.closeDrawer(mNavDrawerList);
}

You can make a public method in ListItems fragment class in which you receive an Item class object and add it in adapter. And then inside your DialogNewItem Fragment, On OK Button click, you can search the ListItems using SupportFragmentManager by using its tag and call the public method you wrote.
The following code might help you.
DialogNewItem class
btnOK.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//new item
final Item newItem = new Item();
//Set its variables to match the users entries on the form
newItem.setTitle(editTitle.getText().toString());
newItem.setDescription(editDescription.getText().toString());
newItem.setTrue(isTrue);
FragmentManager manager = getActivity().getSupportFragmentManager();
ListItems fragment = (ListItems)manager.findFragmentByTag("LISTITEMS");
if(fragment != null){
fragment.createNewItem(newItem);
}
dismiss();
}
});
In your ListItems fragment the following code will depict an ItemAdapter as the data member of the ListViewFragment class and below that is the method you can call to add the item in the adapter.
private ItemAdapter mItemAdapter;
public void createNewItem(Item n) {
mItemAdapter.addItem(n);
}

Add an element from a listView to another listView

I want to create an add to favorites action bar button on the news and if the button is clicked, add the news to a new list adapter in the favorites tab, can you help me please implementing the button and tell me how to create the new list?

You can add button to layout of item in Recyclerview or ListView.
Then set action ClickItemListener. When click add button you can store this data of row item you clicked to Shared Preferences or Sqlite. When you open tab favorite reload view and get data from data you stored.

add a parsed list item to another list

i am working on a xml parsing app- news app.
I've parsed the xml file and transformed it to the listView, and when i click the news i see more detailed info about it. I'd like to implement the "add to favorites" button so that it appears in a list in favorites tab (i've implemented the favorites tab in the tabhost in main activity), can anybody help me to do this? (I don't know how to implement action bar button (add to favorites) and how by clicking it to add it to a listview). Thanks!!!!

viewPager / AsyncTask Implementation: mPager cannot be resolved and GetXMLTask cannot be resolved to a type - Java / Android

I'm getting two errors in eclipse:
GetXMLTask cannot be resolved to a type line 119:
which is
GetXMLTask task = new GetXMLTask(this);
as well as
mPager cannot be resolved line 151: onTabChanged(mPager.getAdapter(), mCurrentTabPosition, position);
I believe I've declared and called both GetXMLTask and mPager correctly so I'm not sure exactly what might be causing this.
Any suggestions are greatly appreciated.

Two problems:
mPager is defined in onCreate() method and you are trying to use it in another method. You should declare it in class level outside any method.
GetXMLTask is an inner class of ImagePagerAdapter. so it is not visible outside it. move this definition into your main class outside ImagePagerAdapter or use it as ImagePagerAdapter.GetXMLTask
