Previously, we learn about how to implement drag and drop control event in Android (Drag and Drop Event in Andriod). Now we see how to delete multiple on multiple selection in Listview. 

In android, you can delete multiple items from list.

In this Article, you will learn how to delete multiple selected items in your listview using a contextual action bar. User can select multiple item, first time long click and after just click.

1.      Create a new project in Eclipse. You need to target Android 3.2 or better.

2.      Add listView in activity_main.xml

 <RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
 
    <ListView
        android:id="@+id/listview"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
    </ListView>
 
</RelativeLayout>

  3.      Create an XML graphical layout for your listview item

 <?xmlversion="1.0"encoding="utf-8"?>
 <LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
      android:background="?android:attr/activatedBackgroundIndicator"
    android:orientation="horizontal">
 
    <ImageView
        android:id="@+id/myImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher"/>
 
    <TextView
        android:id="@+id/textview"
        android:layout_marginLeft="5sp"
        android:layout_gravity="center"
        android:textSize="20sp"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
 
</LinearLayout>

 4.      Add adapter class for bind data in custom listview

 
package com.example.listviewmultipledeletion;
 
import java.util.List;
 
import android.content.Context;
import android.util.SparseBooleanArray;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
 
publicclass MyListViewAdapter extends ArrayAdapter<String> { 
     Context myContext;
     LayoutInflater inflater;
     List<String> DataList;
     private SparseBooleanArray mSelectedItemsIds;
 
     // Constructor for get Context and list
      public MyListViewAdapter(Context context, int resourceId, List<String> lists) {
          super(context, resourceId, lists);
          mSelectedItemsIds = new SparseBooleanArray();
          myContext = context;
          DataList = lists;
          inflater = LayoutInflater.from(context);
     }
 
     // Container Class for item
     privateclass ViewHolder {
          TextView tvTitle;
          ImageView myImg;
     }
 
     public View getView(int position, View view, ViewGroup parent) {
          final ViewHolder holder;
          if (view == null) {
              holder = new ViewHolder();
              view = inflater.inflate(R.layout.listview_item, null);
              // Locate the TextViews in listview_item.xml
          holder.tvTitle = (TextView) view.findViewById(R.id.textview);
 
              // Locate the ImageView in listview_item.xml
          holder.myImg = (ImageView) view.findViewById(R.id.myImage);
              view.setTag(holder);
          } else {
              holder = (ViewHolder) view.getTag();
          }
          // Capture position and set to the TextViews
          holder.tvTitle.setText(DataList.get(position).toString());
 
          // Capture position and set to the ImageView
          holder.myImg.setImageResource(R.drawable.ic_launcher);
          return view;
     }
 
     @Override
     publicvoid remove(String object) {
          DataList.remove(object);
          notifyDataSetChanged();
     }
 
     // get List after update or delete
     public List<String> getMyList() {
          returnDataList;
     }
 
     publicvoid toggleSelection(int position) {
          selectView(position, !mSelectedItemsIds.get(position));
     }
 
     // Remove selection after unchecked
     publicvoid removeSelection() {
          mSelectedItemsIds = new SparseBooleanArray();
          notifyDataSetChanged();
     }
 
     // Item checked on selection
     publicvoid selectView(int position, boolean value) {
          if (value)
              mSelectedItemsIds.put(position, value);
          else
              mSelectedItemsIds.delete(position);
          notifyDataSetChanged();
     }
 
     // Get number of selected item
     publicint getSelectedCount() {
          returnmSelectedItemsIds.size();
     }
 
     public SparseBooleanArray getSelectedIds() {
          returnmSelectedItemsIds;
     }
}

 5.      Add menu for show contextual action bar after select item

 
<?xmlversion="1.0"encoding="utf-8"?>
<menuxmlns:android="http://schemas.android.com/apk/res/android">
    
     <item
        android:id="@+id/selectAll"
        
        android:title="Select All"/>
  <item
        android:id="@+id/delete"
        
        android:title="Delete"/>
</menu>

 6.      Now paste following code in MainActivity class

 
package com.example.listviewmultipledeletion;
 
import java.util.ArrayList;
import java.util.List;
 
import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.util.SparseBooleanArray;
import android.view.ActionMode;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.AbsListView.MultiChoiceModeListener;
import android.widget.ListView;
 
@SuppressLint("NewApi")
publicclass MainActivity extends Activity {
     List<String> myList;
     ListView listView;
     MyListViewAdapter adapter;
 
     @Override
     protectedvoid onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          myList = new ArrayList<String>();
          // Add item in list
          for (int i = 1; i < 81; i++)
              myList.add("Item " + i);
          listView = (ListView) findViewById(R.id.listview);
          // Pass value to MyListViewAdapter Classadapter = new MyListViewAdapter(this, R.layout.listview_item, myList);
          // Binds the Adapter to the ListView
          listView.setAdapter(adapter);
          // define Choice mode for multiple delete
          listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
  listView.setMultiChoiceModeListener(new MultiChoiceModeListener() {
 
              @Override
     publicboolean onPrepareActionMode(ActionMode mode, Menu menu) {
                   // TODO Auto-generated method stub
                   returnfalse;
              }
 
              @Override
              publicvoid onDestroyActionMode(ActionMode mode) {
                   // TODO Auto-generated method stub
 
              }
 
              @Override
      publicboolean onCreateActionMode(ActionMode mode, Menu menu) {
                   // TODO Auto-generated method stub
         mode.getMenuInflater().inflate(R.menu.multiple_delete, menu);
                   returntrue;
 
              }
 
              @Override
            publicboolean onActionItemClicked(final ActionMode mode,
                        MenuItem item) {
                   // TODO Auto-generated method stub
                   switch (item.getItemId()) {
                   case R.id.selectAll:
                        //
                        finalint checkedCount = myList.size();
             // If item is already selected or checked then remove or
                        // unchecked and again select all
                        adapter.removeSelection();
                        for (int i = 0; i < checkedCount; i++) {
                             listView.setItemChecked(i, true);
                             // listviewadapter.toggleSelection(i);
                        }
                 // Set the CAB title according to total checked items
 
            // Calls toggleSelection method from ListViewAdapter Class
 
                        // Count no. of selected item and print it
                        mode.setTitle(checkedCount + " Selected");
                        returntrue;
                   case R.id.delete:
                // Add dialog for confirmation to delete selected item
                        // record.
               AlertDialog.Builder builder = new AlertDialog.Builder(
                                  MainActivity.this);
      builder.setMessage("Do you want to delete selected record(s)?");
 
               builder.setNegativeButton("No", new OnClickListener() {
 
                             @Override
               publicvoid onClick(DialogInterface dialog, int which) {
                                  // TODO Auto-generated method stub
 
                             }
                        });
             builder.setPositiveButton("Yes", new OnClickListener() {
 
                             @Override
             publicvoid onClick(DialogInterface dialog, int which) {
                                  // TODO Auto-generated method stub
                               SparseBooleanArray selected = adapter
                                           .getSelectedIds();
                  for (int i = (selected.size() - 1); i >= 0; i--) {
                                      if (selected.valueAt(i)) {
                                      String selecteditem = adapter
                                          .getItem(selected.keyAt(i));
                          // Remove selected items following the ids
                                        adapter.remove(selecteditem);
                                      }
                                  }
 
                                  // Close CAB
                                  mode.finish();
                                  selected.clear();
 
                             }
                        });
                        AlertDialog alert = builder.create();
                alert.setIcon(R.drawable.questionicon);// dialog Icon
                      alert.setTitle("Confirmation"); // dialog Title
                        alert.show();
                        returntrue;
                   default:
                        returnfalse;
                   }
 
              }
 
              @Override
              publicvoid onItemCheckedStateChanged(ActionMode mode,
                        int position, long id, boolean checked) {
                   // TODO Auto-generated method stub
            finalint checkedCount = listView.getCheckedItemCount();
               // Set the CAB title according to total checked items
                   mode.setTitle(checkedCount + " Selected");
          // Calls toggleSelection method from ListViewAdapter Class
                   adapter.toggleSelection(position);
              }
          });
     }
 
}
 

Now run your application
