QuickContactBadge的用法

来源：互联网发布：linux监听tcp端口数据编辑：程序博客网时间：2024/06/10 00:28

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">

</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);
    }
}
