Android Listview with Onclick Items

Android ListView with onClick items

In your activity, where you defined your listview

you write

listview.setOnItemClickListener(new OnItemClickListener(){   
    @Override
    public void onItemClick(AdapterView<?>adapter,View v, int position){
        ItemClicked item = adapter.getItemAtPosition(position);

        Intent intent = new Intent(Activity.this,destinationActivity.class);
        //based on item add info to intent
        startActivity(intent);
    }
});

in your adapter's getItem you write

public ItemClicked getItem(int position){
    return items.get(position);
}

Android How to set onClick event in list item of ListView

list.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                Intent intent = new Intent(context, SendMessage.class);
                String message = "abcpqr";
                intent.putExtra(EXTRA_MESSAGE, message);
                startActivity(intent);
            }
        });

try this way.

How to add an onClickListener to different items in a ListView row

Create your own Adapter which extends the ArrayAdapter (see this link), override the getView() method and in there you can add OnClickListeners to every View in the ListView's child. To notify the ListView a child is removed, call notifyDataSetChanged() on the ListView's Adapter.

You could solve this using the ListView, but I would suggest using the RecyclerView (Android RecyclerView). RecyclerView has better support for updating its children (like removing, inserting, updating children) and has default animations set.

Adding onClickListener to specific items in ListView

You can define your listView.setOnItemClickListener like this to go to different activity for clicking different element.

listView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view,
                            int position, long id) {
         String item = listView.getItemAtPosition(position);
         Toast.makeText(this,"You selected : " + item,Toast.LENGTH_SHORT).show();
         if(position==0) {
            // Do your code for clicking "Smartphone Plans" example
            // startActivity(new Intent(getApplicationContext(),SmartphonePlans.class));
         }
        else if(position==1) { 
           // Do your code for clicking "Internet Bundles". example
          // startActivity(new Intent(getApplicationContext(),InternetBundles.class));
         }
        else if(position==2) { 
           // Do your code for clicking "Weekend Plans". example 
          //startActivity(new Intent(getApplicationContext(),WeekendPlans.class));*/
    }

});

how to attach a onClick Listener to a listview item on an app widget

The section of Adding behavior to individual items in the official doc say:

As described in Using the AppWidgetProvider Class, you normally use setOnClickPendingIntent() to set an object's click behavior—such as to cause a button to launch an Activity. But this approach is not allowed for child views in an individual collection item (to clarify, you could use setOnClickPendingIntent() to set up a global button in the Gmail app widget that launches the app, for example, but not on the individual list items). Instead, to add click behavior to individual items in a collection, you use setOnClickFillInIntent(). This entails setting up up a pending intent template for your collection view, and then setting a fill-in intent on each item in the collection via your RemoteViewsFactory.

Your RemoteViewsFactory must set a fill-in intent on each item in the collection. This makes it possible to distinguish the individual on-click action of a given item. The fill-in intent is then combined with the PendingIntent template in order to determine the final intent that will be executed when the item is clicked.

Your need to call setOnClickFillInIntent to differentiate the item on-click behavior. Something like this:

public RemoteViews getViewAt(int position) {

        final RemoteViews remoteView = new RemoteViews(
            context.getPackageName(), R.layout.widget_item);

        [...]

        // Next, set a fill-intent, which will be used to fill in the pending intent template
        // that is set on the collection view in StackWidgetProvider.
        Bundle extras = new Bundle();
        extras.putInt(YouWidgetProvider.EXTRA_ITEM, position);
        Intent fillInIntent = new Intent();
        fillInIntent.putExtras(extras);
        // Make it possible to distinguish the individual on-click
        // action of a given item
        remoteView.setOnClickFillInIntent(R.id.item_frame, fillInIntent);

        return remoteView;
    }

Also setPendingIntentTemplate should be use instead of setOnClickPendingIntent to set a single PendingIntent template on the collection. Set the pending intent in onUpdate method corresponding to you subclass of AppWidgetProvider, something like this:

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        // update each of the app widgets with the remote adapter
        for (int i = 0; i < appWidgetIds.length; ++i) {
            ...
            RemoteViews remoteView = new RemoteViews(context.getPackageName(), 
                R.layout.widget_item);
            ...

            // This section makes it possible for items to have individualized behavior.
            // It does this by setting up a pending intent template. Individuals items of a collection
            // cannot set up their own pending intents. Instead, the collection as a whole sets
            // up a pending intent template, and the individual items set a fillInIntent
            // to create unique behavior on an item-by-item basis.
            Intent activityIntent = new Intent(context, ListActivity.class);
            // Set the action for the intent.
            // When the user touches a particular view.
            activityIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
            activityIntent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
            PendingIntent pendingIntent = PendingIntent.getActivity(context, appWidgetIds[i], 
                activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);
            remoteView.setPendingIntentTemplate(R.id.stack_view, pendingIntent);

            appWidgetManager.updateAppWidget(appWidgetIds[i], remoteView);
        }
        super.onUpdate(context, appWidgetManager, appWidgetIds);
    }

Android : How to set onClick event for Button in List item of ListView

You can set the onClick event in your custom adapter's getView method..

check the link http://androidforbeginners.blogspot.it/2010/03/clicking-buttons-in-listview-row.html

How to handle the click event in Listview in android?

I can not see where do you declare context. For the purpose of the intent creation you can use MainActivity.this

 lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                Intent intent = new Intent(MainActivity.this, SendMessage.class);
                String message = "abc";
                intent.putExtra(EXTRA_MESSAGE, message);
                startActivity(intent);
            }
        });

To retrieve the object upon you have clicked you can use the AdapterView:

ListEntry entry = (ListEntry) parent.getItemAtPosition(position);

is it possible to set onClickListener for custom listView item in activity?

1. Update your customButtonListener interface as below:

public interface customButtonListener {
    public void onEditButtonClickListner(int position, String value);
    public void onDeleteButtonClickListner(int position);
}

2. In adapters getView() method set click listener to edit and delete buttons:

@NonNull
@Override
public View getView(final int position, @Nullable View convertView, @NonNull final ViewGroup parent) {

    ............
    ...................

    // Edit
    viewHolder.editBtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            if (customListner != null) {
                customListner.onEditButtonClickListner(position, getItem(position).getExerciseName());
            }
        }
    });

    // Delete
    viewHolder.deleteBtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            if (customListner != null) {
                customListner.onDeleteButtonClickListner(position);
            }
        }
    });

    return convertView;
}

3. In your activity, add CustomButtonListener to your ListView:

A. Get item position from `onEditButtonClickListner()` and get `workoutExercise` object and pass it to another activity 
B. Get item position from `onDeleteButtonClickListner()` and delete item and upadte ListView.

Add below codes in your Activity:

    ..........
    .................

    listAdapter.setCustomButtonListener(create_workout.this);
    exercisesList.setAdapter(listAdapter);

    exercisesList.setCustomButtonListener(new WorkoutExerciseListAdapter.customButtonListener() {

        @Override
        public void onEditButtonClickListner(int position, String value) 
        {
            // Item
            WorkoutExercise workoutExercise = workoutExercises.get(position);

            // Do something with object workoutExercise 
        }

        @Override
        public void onDeleteButtonClickListner(int position) 
        {
            // Delete
            workoutExercises.remove(position);

            // Update ListView
            listAdapter.notifyDataSetChanged();
        }
    });

Hope this will help~
