Why do the selected contacts not appear in the textview?_问答_开发者

I am creating a multiple choice layout for contact list. I successfully pick the contacts. However, instead of displaying the contact name in text view,it appear as String value. I just want the contact name to appear in TextView not the String values.

I got 2 classes. One class is to pick contact. While the other class is for browsing and selecting the contacts.

Selected Contact Activity

package com.droidnova.android.samples;

 import android.app.Activity;
  import android.content.Intent;
  import android.database.Cursor;
  import android.os.Bundle;
  import android.provider.Contacts.People;
  import android.provider.ContactsContract.Contacts;
  import android.view.View;
  import android.widget.Button;


   public class SelectContact extends Activity {
 private static final int PICK_CONTACT = 0;
 private Button btnPick;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.button);

        btnPick = (Button)findViewById(R.id.button);
        btnPick.setOnClickListener(new MyOnClickListener());


    }
    @Override
     protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == PICK_CONTACT) {
            if (resultCode == RESULT_OK) {
                Cursor contact = getContentResolver().query(data.getData(), null, null, null, null);
                contact.moveToFirst();
                String name = contact.getString(contact.getColumnIndexOrThrow(People.NAME));


        }

    }
       }
    private class MyOnClickListener implements View.OnClickListener {
     @Override
   public void onClick(View v) {
         startActivityForResult(new Intent(Intent.ACTION_PICK),PICK_CONTACT);
  }
  }
}

Contacts Activity

 public class Contacts extends ListActivity {
ListView list;
TextView Selection;



private static String[] PROJECTION = new String[]
{
    People._ID,
    People.NAME,
    People.NUMBER,
};

  @Override
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    list=(ListView)findViewById(android.R.id.list);
    Cursor cursor = getContentResolver().query(People.CONTENT_URI, 
            PROJECTION, null, null, null);
    startManagingCursor(cursor);

    ListAdapter adapter = new SimpleCursorAdapter(this,android.R.layout.simple_list_item_multiple_choice,
            cursor,new String[]{People.NAME},new int[]{android.R.id.text1});

    getListView().setChoiceMode(2);
   setListAdapter(adapter);
    Selection = (TextView)findViewById(R.id.selection);
   }
  @Override

  protected void onListItemClick(ListView parent,View v,int position,long id){
  Selection.setText("");
  SparseBooleanArray chosen = parent.getCheckedItemPositions();
  for(int i=0;i<chosen.size();i++)
  {
          Log.d("Selection", "index:"+i+";key:"+chosen.keyAt(i) +";value:"+chosen.valueAt(i)
                  +";"+PROJECTION[chosen.keyAt(i)]);

          if(chosen.valueAt(i)){
              Selection.append(PROJECTION[chosen.keyAt(i)]+"");
          }

      }
  }

}

This is my logcat:
