How to reference a view inside an element from my ListView?

So I have created a custom adapter for my ListView with three Views - TextView, ImageView and a basic View:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/AllNotesFragment">
<TextView
android:id="#+id/addNoteTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_marginStart="30dp"
android:layout_marginTop="25dp"
android:textSize="18sp"
android:gravity="center"
android:fontFamily="#font/ukij_qolyazma"
android:text="+new"
/>
<ImageButton
android:id="#+id/deleteNoteImageButton"
android:layout_width="50dp"
android:layout_height="70dp"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:layout_marginTop="0dp"
android:layout_marginEnd="30dp"
android:textSize="24sp"
android:gravity="center"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:fontFamily="#font/ukij_qolyazma"
/>
<View
android:id="#+id/underlineView"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:layout_marginHorizontal="30dp"
android:layout_marginTop="70dp"
android:background="#color/colorMainDark" />
<ListView
android:id="#+id/notesListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_marginTop="75dp"
android:layout_marginBottom="0dp">
</ListView>
I have created and instantiated the ListView
notesListView = view.findViewById(R.id.notesListView);
And filled it with a bunch of my notes
notes = (ArrayList<Note>) db.getAllNotesForDay(NotesForDayActivity.getRememberDay(),
NotesForDayActivity.getRememberMonth(),
NotesForDayActivity.getRememberYear());
for (Note note : notes) {
noteTitles.add(note.getTitle());
}
NotesListAdapter adapter = new NotesListAdapter(((NotesForDayActivity) getActivity()).getContext(), notes);
notesListView.setAdapter(adapter);
With my custom adapter:
public class NotesListAdapter extends BaseAdapter {
private static final String TAG = "NotesListAdapter";
public static Context context;
private RelativeLayout notesListRelativeLayout;
private TextView noteTitleTextView;
private ImageView tickImage;
private View underlineView;
private List<Note> notes;
// !
private View listItemsView;
public NotesListAdapter(Context context, List<Note> notes) {
this.notes = notes;
this.context = context;
}
#Override
public int getCount() {
return NotesForDayActivity.getCountNotes();
}
#Override
public Object getItem(int position) {
return notes.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
listItemsView = convertView;
if (listItemsView == null) {
listItemsView = LayoutInflater.from(NotesForDayActivity.context).inflate(R.layout.notes_list_layout, null);
}
underlineView = listItemsView.findViewById(R.id.underlineView);
notesListRelativeLayout = (RelativeLayout) listItemsView.findViewById(R.id.notesListRelativeLayout);
noteTitleTextView = (TextView) listItemsView.findViewById(R.id.noteTitleTextView);
tickImage = (ImageView) listItemsView.findViewById(R.id.tickImageView);
noteTitleTextView.setText(notes.get(position).getTitle());
return listItemsView;
}
I can access an item inside my ListView with a OnItemClickListener, but I do not know how to access a View inside that particular Item of my ListView.
So If I set my OnClick like this:
notesListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
How can I reference one of the three Views in that item. For example I need to set the visibility of my imageview:
Any help is appreciated.

Try this, OnItemClickListener will return the view, so that you can get access through that view
notesListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
ImageView tickImage = view.findViewById(R.id. tickImageView);
if(tickImage!=null){
tickImage.setVisibility(View.GONE);
}
}
});

RecyclerView - I can't add more than 1 line

I'm with a problem to add more than 1 line(item) in my RecyclerView, the item overwrites the previous one when I tap the button, but if I create a List<> with data in hardcoded on onCreate, It works adding more than 1 line in the RecyclerView. Follow the code:
ListChecklistAdapter
public class ListChecklistAdapter extends RecyclerView.Adapter<ListChecklistAdapter.ListChecklistViewHolder> {
private List<Checklist> mChecklist;
private Context mCtx;
public ListChecklistAdapter(Context ctx, List<Checklist> checklists) {
mCtx = ctx;
mChecklist = checklists;
}
#Override
public ListChecklistViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(mCtx).inflate(R.layout.item_checklist, parent, false);
return new ListChecklistViewHolder(view);
}
#Override
public void onBindViewHolder(ListChecklistViewHolder holder, int position) {
holder.cbItem.setText(mChecklist.get(position).getDescricao());
holder.cbItem.setChecked(mChecklist.get(position).isCheckado());
}
#Override
public int getItemCount() {
return mChecklist.size();
}
public class ListChecklistViewHolder extends RecyclerView.ViewHolder {
#BindView(R.id.item_checkbox)
CheckBox cbItem;
public ListChecklistViewHolder(View view) {
super(view);
ButterKnife.bind(this, view);
}
}
public void refreshData(List<Checklist> item) {
this.mChecklist.clear();
this.mChecklist.addAll(item);
notifyDataSetChanged();
}
}
item_checklist
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">

android:id="#+id/item_checkbox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:paddingLeft="6dp"
android:text=" "
tools:text="Exemplo de item de lista" />
</RelativeLayout>
MainActivity
public class MainActivity extends AppCompatActivity {
#BindView(R.id.rcv_lista)
RecyclerView rvLista;
int valor;
private List<Checklist> lista;
private ListChecklistAdapter listChecklistAdapter;
#BindView(R.id.btn_add_item)
Button btnAdd;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
}
private int cont() {
return valor++;
}
public void novoItem(View view) {
lista = new ArrayList<>();
lista.add(new Checklist("Item " + (cont() + 1), true));
loadRecycler(lista);
}
private void loadRecycler(List<Checklist> lista) {
if (listChecklistAdapter == null) {
Log.i("LOG", "IF");
listChecklistAdapter = new ListChecklistAdapter(this, lista);
rvLista.setAdapter(listChecklistAdapter);
rvLista.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
rvLista.addItemDecoration(new DividerItemDecoration(this, 1));
return;
} else {
Log.i("LOG", "ELSE");
listChecklistAdapter.refreshData(lista);
listChecklistAdapter.onAttachedToRecyclerView(rvLista);
}
}
}

Just remove this line this.mChecklist.clear(); from your refreshData() method.
public void refreshData(List<Checklist> item) {
this.mChecklist.addAll(item);
notifyDataSetChanged();
}

#Nilesh Rathod solved the problem! I just deleted this.mChecklist.clear(); from the ListCheckAdapter.java > refreshData()
Thanks for everyone to help too!

Show and hide listview

I want to do list view like this. What I want is when user touch 1st item, the 2nd item row appear. When user touch 3rd row item the previous item automatically hide again. How can i achieve this instead of using expandable listview? guide me in achieving this. Thanks in advance.

I'm sorry that i'm a bit busy, so i can't write the code right now. But below is the way which you can use to get what you want. I will add code when i will get time.
There is a parameter name "android:animateayoutchanges", apply it to the parent of your view which will be visible and invisible.
Save the position of the item which you have clicked and expanded.
When you click that item, Set the visibility of the view to visible.
When you again click on that item position, set that item's visibility to gone.
When you click some other item, then set the visibility of the stored item position to gone, set currently selected item's visibility to visible and store it's position.
That's it.
android:animateayoutchanges is used so that when you set the visibility to visible or gone and views move upward or downward, then this movement will have smooth animation.
I will update my answer with code later But you will get an idea from above steps.

How do I use the swipe gesture to remove cards within a recycleview?

How do I use the swipe gesture to remove cards from my recycle-view in the same way that it is done in Google-now etc. So far I've created the cardview application but it's removing cards via a swipe gesture which I'm having problems with. I haven't found a single tutorial or question answered on this website which could help.
Any help would be very much appreciated. My code is below.
MyActivity
public class MyActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_my);
setContentView(R.layout.activity_my);
RecyclerView recList = (RecyclerView) findViewById(R.id.cardList);
recList.setHasFixedSize(true);
LinearLayoutManager llm = new LinearLayoutManager(this);
llm.setOrientation(LinearLayoutManager.VERTICAL);
recList.setLayoutManager(llm);
ContactAdapter ca = new ContactAdapter(createList(30));
recList.setAdapter(ca);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.my, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private List<ContactInfo> createList(int size) {
List<ContactInfo> result = new ArrayList<ContactInfo>();
for (int i=1; i <= size; i++) {
ContactInfo ci = new ContactInfo();
ci.name = ContactInfo.NAME_PREFIX + i;
ci.surname = ContactInfo.SURNAME_PREFIX + i;
ci.email = ContactInfo.EMAIL_PREFIX + i + "#test.com";
result.add(ci);
}
return result;
}

You can use below code (ItemTouchHelper.SimpleCallback from Android support V7) to remove the cards from RecyclerView using swipe gesture
ItemTouchHelper.SimpleCallback simpleItemTouchCallback = new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
#Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
return false;
}
#Override
public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
contacts.remove(viewHolder.getAdapterPosition());
ca.notifyItemRemoved(viewHolder.getAdapterPosition());
}
#Override
public void onMoved(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, int fromPos, RecyclerView.ViewHolder target, int toPos, int x, int y) {
super.onMoved(recyclerView, viewHolder, fromPos, target, toPos, x, y);
}
};
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(simpleItemTouchCallback);
itemTouchHelper.attachToRecyclerView(recList);

Gridview adapter images with title name for images group

I have a gridView witch contains a group of images with two columns, what I want to do is to put a title for a group of images.
Now I can do that but the problem that title is that the title is only in one column and the second column is always empty, how can I put the title in the two columns?
Here is my adapter:
public class MultimediaPhotosAdapter extends BaseAdapter {
private Context mContext;
private List<ImagesDto> imagesDto = new ArrayList<ImagesDto>();
ImagesFlickrDto imagesFlickrDto;
final String formatImage = ImagesNameFormat.FORMAT_IMAGE_DEFAULT.getImagesNameFormat();

this.gridViewImages = gridViewImages;
this.mContext = context;
}

return 0;
}
