So erhalten Sie die ausgewählten Kontakte aus Kontrollkästchen (Android)

Question

Ich erstelle eine Gruppe Android SMS. Daher brauche ich ein Kontrollkästchen. Aber, mein Problem ist, kann ich nicht herausfinden, wie man die ausgewählten Kontakte bekommt?

Das ist mein Layout:

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/topLayout" 
android:orientation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:layout_centerHorizontal="true"> 

<ListView 
android:id="@+id/list" 
android:layout_width="fill_parent" android:layout_height="fill_parent"  android:choiceMode="multipleChoice"> 
</ListView> 

<ImageView android:id="@+id/contact_image" 
    android:src="@drawable/icon" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
/> 
<TextView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Name: " 
    android:id="@+id/contact_name" 
    android:textSize="18dip" 
    android:layout_below="@id/contact_image"  
     /> 

     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="Phone: " 
      android:id="@+id/phone_number" 
      android:textSize="28dip" 
      android:layout_below="@id/contact_name" 


     /> 
     <CheckBox android:id="@+id/checkBox" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:checked="false" android:layout_alignParentRight="true"  android:focusable="false"> 
    </CheckBox> 

    </RelativeLayout>

    listView.setAdapter(new ArrayAdapter<String>(this, 
    android.R.layout.simple_list_item_multiple_choice, lv_items)); 





    Cursor cursor = getContentResolver().query(People.CONTENT_URI, 
      new String[]{People._ID,People.NAME,People.NUMBER}, null, null, null); 
    startManagingCursor(cursor); 

    // start mappings 
    String[] columns = new String[] {People.NAME, People.NUMBER}; 
    int[] names = new int[] {R.id.contact_name, R.id.phone_number};

Answer 2

Das sind meine aktualisierten Codes. Wann immer, ich klicke auf die 'Mark' Menü-Taste, es erhält nicht das ausgewählte Element und Anzeige bei Text bearbeiten.
