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); } }
