[android] How to dynamically remove items from ListView on a button click?

I am working on an app that requires removing items from a ListView on a button event.

I tried to remove it from ArrayList and create the whole new adapter and load the list again. As my list is huge, doing this will affect the performance of my app. So I was wondering if there is any other way by which I could remove an item from my list dynamically.

Edit: I tried what you said.

When I removed one item it worked perfectly, but as I increase the number of selected items it starts giving me IndexOutOfBoundException.

Here's my code:

public void onClick(View view)
{
    SparseBooleanArray checkedPositions = new SparseBooleanArray();
    checkedPositions.clear();
    checkedPositions = lv.getCheckedItemPositions();
    int size = checkedPositions.size();
    if(size != 0)
    {

        for(int i = 0; i <= size; i++)
        {
            if(checkedPositions.valueAt(i))
            {
                list.remove(notes.getItem(checkedPositions.keyAt(i)));
                notes.notifyDataSetChanged();
            }
        }
    }
        else{}
}

Here, notes is a reference to an object of SimpleAdapter.

Have a button on list and let it onclick feature in xml like to get postion first

public void OnClickButton(View V){
  final int postion = listView.getPositionForView(V);
    System.out.println("postion selected is : "+postion);
Delete(postion);

}
public void Delete(int position){
    if (adapter.getCount() > 0) {

        //Log.d("largest no is",""+largestitemno);
        //deleting the latest added by subtracting one 1 
        comment = (GenrricStoring) adapter.getItem(position);
        //Log.d("Deleting item is: ",""+comment);
        dbconnection.deleteComment(comment);
        List<GenrricStoring> values = dbconnection.getAllComments();
        //updating the content on the screen
        this.adapter = new UserItemAdapter(this, android.R.layout.simple_list_item_1, values);
        listView.setAdapter(adapter);
    }
    else
    {
        int duration = Toast.LENGTH_SHORT;
        //for showing nothing is left in the list
        Toast toast = Toast.makeText(getApplicationContext(),"Db is empty", duration);
        toast.setGravity(Gravity.CENTER, 0, 0);

        toast.show();
    }

}

You can remove item from list view like this: or you can choose on your Button event which item have to be removed

public class Third extends ListActivity {
private ArrayAdapter<String> adapter;
private List<String> liste;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_third);
     String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2" };
     liste = new ArrayList<String>();
     Collections.addAll(liste, values);
     adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, liste);
     setListAdapter(adapter);
}
 @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
     liste.remove(position);
     adapter.notifyDataSetChanged();
  }
}

 List<String> entries;
 private ArrayAdapter<String> categoryAdapter;
 //Your list of entries {Example: <"category1","category2","category3">}
 entries =  new ArrayList<String>();
 categoryAdapter = new ArrayAdapter<String>(ViewBeaconsActivity.this,
                                   android.R.layout.simple_list_item_1, entries);
 //Remove that specific category from the list
 entries.remove(categoryName);
 //Notify the adapter that your dataset has changed.
 categoryAdapter.notifyDataSetChanged();

adapter.remove(arraylist.get(position));
adapter.notifyDataSetChanged();

or you can call again

setListAdapter(adapter)

<ImageView
    android:id="@+id/btnDelete"
    android:layout_width="35dp"
    android:layout_height="match_parent"
    android:layout_alignBottom="@+id/editTipo"
    android:layout_alignParentRight="true"
    android:background="@drawable/abc_ic_clear"
    android:onClick="item_delete_handler"/>

And create Event item_delete_handler,

This worked for me. Hope it helps someone. :)

SimpleAdapter adapter = (SimpleAdapter) getListAdapter();
this.resultsList.remove((int) info.id);
adapter.notifyDataSetChanged();

As for your last question, here's the problem illustrated with a simple example:

Let's say that your list contains 5 elements: list = [1, 2, 3, 4, 5] and your list of items to remove (i.e. the indices) is indices_to_remove = [0, 2, 4]. In the first iteration of the loop you remove the item at index 0, so your list becomes list = [2, 3, 4, 5]. In the second iteration, you remove the item at index 2, so your list becomes list = [2, 3, 5] (as you can see, this removes the wrong element). Finally, in the third iteration, you try to remove the element at index 4, but the list only contains three elements, so you get an out of bounds exception.

Now that you see what the problem is, hopefully you will be able to come up with a solution. Good luck!

      private List<DataValue> datavalue=new ArrayList<Datavalue>;

     @Override
    public View getView(int position, View view, ViewGroup viewGroup) {

            view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                datavalue.remove(position);
                notifyDataSetChanged();
            }
        });
    }
    }
