I want to remove List element on Click of Delete Button or toggle the status of task with checkBox,I'm not even seeing the Toast that is present in clickListener of Checkbox and Delete Button,there's just nothing happening, unable to figure out how to do that..

Make a Callback interface to solve your problem. I think this the best way what you want to achieve.
OnItemClickListener
public class OnItemClickListener implements View.OnClickListener {
private int position;
private OnItemClickCallback onItemClickCallback;
public OnItemClickListener(int position, OnItemClickCallback
onItemClickCallback) {
this.position = position;
this.onItemClickCallback = onItemClickCallback;
}
#Override
public void onClick(View view) {
onItemClickCallback.onItemClicked(view, position);
}
public interface OnItemClickCallback {
void onItemClicked(View view, int position);
}
}
In your adapter class
private OnItemClickListener.OnItemClickCallback onItemClickCallback;
public CustomAdapter(#NonNull Context context, ArrayList<listClass> arr,
OnItemClickListener.OnItemClickCallback onItemClickCallback)
{
super(context,R.layout.detail, arr);
this.arr = new ArrayList<listClass>(0);
this.onItemClickCallback = onItemClickCallback;
this.arr.addAll(arr);
}
and
holder.imageButton.setOnClickListener(new OnItemClickListener(position,
onItemClickCallback));
In your activity
private OnItemClickListener.OnItemClickCallback
onItemDeleteClickCallback = new
OnItemClickListener.OnItemClickCallback() {
#Override
public void onItemClicked(View view, int position) {
//here you will get delete item pos
}
};
and
CustomAdapter adapter = new CustomAdapter(MainActivity.this, arr,
onItemDeleteClickCallback );
final ListView lv = findViewById(R.id.vishulv);
lv.setAdapter(adapter);
Hope this will help you.

Try this in your adapter
holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (buttonView.isChecked()) {
//checked
Toast.makeText(getContext(),"active checkbox",Toast.LENGTH_LONG).show();
}
else
{
//not checked
Toast.makeText(getContext(),"inactive checkbox",Toast.LENGTH_LONG).show();
}
});

Deleting the clicked item in the listview Android

My code java. I'm getting data from the intent as an array. I am using arraylist,listview and custom adapter. I can show the incoming data using listview. I want the item I clicked to be deleted. The name of my delete button "deleteshop" in customadapter. How can I do that ?
My code;
final ListView list = findViewById(R.id.list);
final ArrayList<SubjectData> arrayList = new ArrayList<SubjectData>();
final String[] cartList = getIntent().getStringArrayExtra("saleData");
arrayList.add(new SubjectData("", ""));
final int cartListLength = cartList.length;
int counter = 0;
String lastItem = "";
for (String e : cartList) {
counter += 1;
if (e == "" || e == null) {
lastItem = cartList[counter-3];
break;
}
String productPhoto = "";
switch (e) {
case "1 PC GREEN COLA x 10.00 TL":
productPhoto = "cc";
break;

productPhoto = "";
break; }
arrayList.add(new SubjectData(e, productPhoto));;
}
arrayList.remove(arrayList.size()-1);
arrayList.remove(arrayList.size()-1);
arrayList.add(new SubjectData("*** GRAND TOTAL TL:" + lastItem + " ***", "arrowgreen"));
arrayList.add(new SubjectData("", ""));
arrayList.add(new SubjectData("", ""));
final CustomAdapter customAdapter = new CustomAdapter(this, arrayList);
list.setAdapter(customAdapter);

public SubjectData(String subjectName, String image) {
this.SubjectName = subjectName;

If you want to delete clicked item from your list view then you can use this code .I tested and its deleting smoothly , after deleting its updating list also.
CustomAdapter customAdapter = new CustomAdapter(this,R.layout.list_row, arrayList);
list.setAdapter(customAdapter);
// after setting adapter put this code
// and update your ui again using set adapter
Log.e("Custom",""+arrayList.size());
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
arrayList.remove(i);
list.setAdapter(customAdapter);
}
});
This is not a best solution but ulternative , suppose if you want to update your adapter on click of deletebutton first create one interface , here is sample
public interface MyInterface{
public void deleteItem(int pos);
}
Now in your main activity use like this MainActivity extends AppCompatActivity implements MyInterface and place your interface method public void deleteItem(int pos){ arrayList.remove(pos); list.setAdapter(customAdapter); }
After that call this method from your adapter like below
deleteshop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, "Delete",
Toast.LENGTH_SHORT).show();
//Actually change your list of items here
if (context instanceof SampleList) {
((MainActivity)context).deleteItem(position);
}
}
});

UltimateRecycleView : SetLoadMoreView is Not Working

I am currently working with Android and UltimateRecycleView. I manage to make the ultimaterecycleview working, but when I tried to use the load more functionality, the bottom progress bar is not showing (although the data is loaded). Anyone has experienced this problem? Can you please help me to find out what is wrong?
Here is the code :

Android OnClickListener not working with custom adapter

I've made a custom adapter for a ListView in order to display a String and an ImageButton within the same row. A row is generated every time the add button is clicked. The string is taken from the EditText field, while the ImageButton bin_button is allocated dinamically. Everything works fine except I can't make the bin_buttons fire an OnClick event.
I've tried several solutions. Here bin_button_listener is generated outside the add_button OnClickListener and then set. I've also tried to set listeners with a new OnClickListener every time a new bin_button was created.
Here some code:
Row layout list_string_button_layout.xml:
<TextView
android:id="#+id/list_item_string"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingStart="8dp"
android:paddingEnd="0dp"
android:paddingTop="8dp"
android:textSize="18sp"
android:textStyle="bold"/>
<ImageButton
android:id="#+id/delete_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="10dp"
android:paddingEnd="5dp"
android:background="#00ffffff"
android:src="#drawable/ic_delete_black_18dp"
android:layout_alignBottom="#+id/list_item_string"
android:layout_alignParentEnd="true"
android:focusableInTouchMode="true"
/>
</RelativeLayout>
Activity layout activity_search.xml:
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ingredient_text_input"
android:hint="#string/start_typing_ingredient"
android:layout_marginTop="52dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_button"

first of all
u should move your logic to onCreate() see: Difference between onCreate() and onStart()?
second
u should in your method in adapter :
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// 1. inflate view
// 2. find button
// 3. assign here listener to bin button
// i advice to use convert view pattern
}
some hints :
create data object describing row item
public class BinRow {
private String _someString;
private Drawable _imageDrawable; // (or resource id name)
public String getString() {
return _someString;
}
public Drawable getImage() {
return _imageDrawable;
}
public BinRow(String someText, Drawable imageDrawable) {
_someText = someText;
_imageDrawable = imageDrawable;
}
}
here u have adapter example ( u need adjust Album - to your BinRow & layout for row & convert view items in view holder ) - this should show you idea how adapter works :
public class AlbumAdapter extends BaseAdapter implements IListAdapter<Album> {
private List<Album> _albums;
private Context _context;
private LayoutInflater _layoutInflater;
static class ViewHolder {
ImageView imageView;
TextView albumName;
public ViewHolder(View v) {
imageView = (ImageView) v.findViewById(R.id.image);
albumName = (TextView) v.findViewById(R.id.tvAlbumName);
}
}
public AlbumAdapter(List<Album> albums) {
if(albums == null) {
_albums = new ArrasyList<>();
} else {
_albums = albums;
}
}
#Override
public int getCount() {
return _albums.size();
}
#Override
public Album getItem(int position) {
return _albums.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, final ViewGroup parent) {
final Album album = getItem(position);
if (_context == null) {
_context = parent.getContext();
}
if (_layoutInflater == null) {
_layoutInflater = LayoutInflater.from(_context);
}
View _view = convertView;
ViewHolder viewHolder;
if (_view == null) {
_view = _layoutInflater.inflate(R.layout.album_item_layout, parent, false);
viewHolder = new ViewHolder(_view);
_view.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) _view.getTag();
}
viewHolder.albumName.setText(album.getAlbumDescription());
// here u can set: image to image view & listener to image
// image view could be a button
viewHolder.imageView.setOnClickListener(View.OnClickListener);
return _view;
}
#Override
public void add(Album listElement) {
_albums.add(listElement);
}
#Override
public void addAll(List<Album> listOfElements) {
_albums.addAll(listOfElements);
}
#Override
public void clear() {
_albums.clear();
}
#Override
public void remove(Album listElement) {
_albums.remove(listElement);
}
}
public interface IListAdapter<T> {
void add(T listElement);
void addAll(List<T> listOfElements);
void clear();
void remove(T listElement);
}
above interface serves as helper for adapter list methods

list.setAdapter(adapter);
dialog.dismiss();
}else {

instead of add to list add the item in adapter and then call notifyDataSetChanged

Please help me.
When I pressed OK button then my apps has stop but there is no error even eclipse do't show any error.
How I can solve it?
Please help me.

This like inputMethodManager.hideSoftInputFromWindow(wishEditText.getWindowToken(), 0); might be giving you a NullPointerException
