QuickContactBadge的用法

首先上个运行效果图：

下边是ListView 中单个Item的布局文件：

<?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:paddingLeft="0dip"
     android:paddingRight="9dip"
     android:layout_height= "wrap_content"
     android:minHeight="48dip" android:id="@+id/contactItemRelLayout">    <QuickContactBadge
         android:id="@+id/badge"
         android:layout_marginLeft="2dip"
         android:layout_marginRight="14dip"
         android:layout_marginTop="4dip"
         android:layout_marginBottom="3dip"
         android:layout_alignParentLeft="true"
         android:layout_alignParentTop="true"
         android:layout_height= "wrap_content"
         android:layout_width= "wrap_content"
         android:src="@drawable/default_head_pic"
         style="?android:attr/quickContactBadgeStyleWindowSmall" />    <TextView
         android:id="@+id/name"
         android:textAppearance="?android:attr/textAppearanceMedium"
         android:paddingLeft="2dip"
         android:layout_centerVertical="true"
         android:layout_toRightOf="@id/badge"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" android:text="哈哈"/>
     <TextView 
         android:id="@+id/phone"
         android:textAppearance="?android:attr/textAppearanceMedium"
         android:paddingRight="2dip"
         android:layout_centerVertical="true"
         android:paddingLeft="4dip"
         android:layout_toRightOf="@id/name"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" android:text="12345678901"/>
     <CheckBox    
         android:id="@+id/cb"    
         android:layout_width="wrap_content"    
         android:layout_height="wrap_content"    
         android:layout_centerVertical="true"
         android:focusable="false"    
         android:focusableInTouchMode="false"    
         android:clickable="false" 
         android:layout_alignParentRight="true"
         android:checkMark="?android:attr/listChoiceIndicatorMultiple"/></RelativeLayout>

下边是自定义的Adapter，这个很关键，和一般的Adapter不一样，不是继承自BaseAdapter

package abc.qiao.contact.adapter;
import java.util.ArrayList;
 import java.util.List;import abc.qiao.contact.R;
 import android.content.Context;
 import android.database.CharArrayBuffer;
 import android.database.Cursor;
 import android.provider.ContactsContract;
 import android.provider.ContactsContract.Contacts;
 import android.view.View;
 import android.view.ViewGroup;
 import android.widget.CheckBox;
 import android.widget.QuickContactBadge;
 import android.widget.ResourceCursorAdapter;
 import android.widget.TextView;public class ContactAdapter extends ResourceCursorAdapter{
  private Context context2;
  static final int SUMMARY_ID_COLUMN_INDEX = 0;
     static final int SUMMARY_NAME_COLUMN_INDEX = 1;
     static final int SUMMARY_STARRED_COLUMN_INDEX = 2;
     static final int SUMMARY_TIMES_CONTACTED_COLUMN_INDEX = 3;
     static final int SUMMARY_PRESENCE_STATUS_COLUMN_INDEX = 4;
     static final int SUMMARY_PHOTO_ID_COLUMN_INDEX = 5;
     static final int SUMMARY_LOOKUP_KEY = 6;
     static final int SUMMARY_HAS_PHONE_COLUMN_INDEX = 7;
     
     private List<Long> contactIDList = new ArrayList<Long>();
     
  public ContactAdapter(Context context, int layout, Cursor c) {
   super(context, layout, c);
   contactIDList.clear();
   this.context2 = context;
  } @Override
  public View newView(Context context, Cursor cursor, ViewGroup parent) {
   // TODO Auto-generated method stub
   View view = super.newView(context, cursor, parent);
   ContactListItemCache cache = new ContactListItemCache();
   cache.nameView = (TextView)view.findViewById(R.id.name);
   cache.photoView = (QuickContactBadge)view.findViewById(R.id.badge);
   cache.phoneView = (TextView)view.findViewById(R.id.phone);
   cache.checkBox = (CheckBox)view.findViewById(R.id.cb);
   view.setTag(cache);
   return view;
  } @Override
  public void bindView(View view, Context context, Cursor cursor) {
   // TODO Auto-generated method stub
   final ContactListItemCache cache = (ContactListItemCache) view.getTag();
         // Set the name
         cursor.copyStringToBuffer(SUMMARY_NAME_COLUMN_INDEX, cache.nameBuffer);
         int size = cache.nameBuffer.sizeCopied;
         cache.nameView.setText(cache.nameBuffer.data, 0, size);
         final long contactId = cursor.getLong(SUMMARY_ID_COLUMN_INDEX);
         cache.phoneView.setText(getPhoneNumbersByContactID(contactId).toString());
 //        cache.checkBox.setChecked(false);
         contactIDList.add(contactId);
         final String lookupKey = cursor.getString(SUMMARY_LOOKUP_KEY);
         cache.photoView.assignContactUri(Contacts.getLookupUri(contactId, lookupKey));
  }
  
  final static class ContactListItemCache {
         public TextView nameView, phoneView;
         public QuickContactBadge photoView;
         public CharArrayBuffer nameBuffer = new CharArrayBuffer(128);
         public CheckBox checkBox;
     }
  
  public List<Long> getContactIdList(){
   return this.contactIDList;
  }
  private String getPhoneNumbersByContactID(Long _id){
   Cursor cursor = context2.getContentResolver().query(
     ContactsContract.CommonDataKinds.Phone.CONTENT_URI,  
                 null,  
                 ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "="  
                 + Long.toString(_id), null, null);
   String phoneNumber = "";
   while(cursor.moveToNext()){
    String strNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
    phoneNumber += strNumber + ",";
   }
   cursor.close();
   String trailedPhoneNumber = phoneNumber.substring(0, phoneNumber.length() - 1);
   return trailedPhoneNumber;
  }
  
  public void notifyall(){
   notifyDataSetChanged();
  }
 }下边是Activity的代码
 
package abc.qiao.contact;
import abc.qiao.contact.adapter.ContactAdapter;
 import android.app.Activity;
 import android.database.Cursor;
 import android.os.Bundle;
 import android.provider.ContactsContract.Contacts;
 import android.widget.ListView;public class ContactSearchActivity extends Activity {
  ListView listView = null;
  ContactAdapter adapter = null;
  
  static final String[] CONTACTS_SUMMARY_PROJECTION = new String[] {
         Contacts._ID, // 0
         Contacts.DISPLAY_NAME, // 1
         Contacts.STARRED, // 2
         Contacts.TIMES_CONTACTED, // 3
         Contacts.CONTACT_PRESENCE, // 4
         Contacts.PHOTO_ID, // 5
         Contacts.LOOKUP_KEY, // 6
         Contacts.HAS_PHONE_NUMBER, // 7
  };
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
         init();
         initData();
     }
     
     private void init(){
      listView = (ListView)findViewById(android.R.id.list);
      listView.setBackgroundDrawable(getWallpaper());
      listView.setCacheColorHint(00000000);//不加这个会出现滑动ListView时出现黑屏的现象
     }
     
     private void initData(){
      String select = "((" + Contacts.DISPLAY_NAME + " NOTNULL) AND ("
         + Contacts.HAS_PHONE_NUMBER + "=1) AND ("
         + Contacts.DISPLAY_NAME + " != '' ))";
      Cursor c =
             getContentResolver().query(Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select,
             null, Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
      adapter = new ContactAdapter(ContactSearchActivity.this, R.layout.contact_item_layout2, c);
      listView.setAdapter(adapter);
     }
 }
