ResourceCursorAdapter

何为QuickContactBadge 如下图：
2011.07.07——— android QuickContactBadge

这个我主要是在apidemo中看到的代码如下：

package com.example.android.apis.app;import com.example.android.apis.R;import android.app.ListActivity;import android.content.Context;import android.database.CharArrayBuffer;import android.database.Cursor;import android.os.Bundle;import android.provider.ContactsContract.Contacts;import android.view.View;import android.view.ViewGroup;import android.widget.QuickContactBadge;import android.widget.ResourceCursorAdapter;import android.widget.TextView;public class QuickContactsDemo extends ListActivity {    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    };    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;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        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");        startManagingCursor(c);        ContactListItemAdapter adapter = new ContactListItemAdapter(this, R.layout.quick_contacts, c);        setListAdapter(adapter);    }    private final class ContactListItemAdapter extends ResourceCursorAdapter {        public ContactListItemAdapter(Context context, int layout, Cursor c) {            super(context, layout, c);        }        @Override        public void bindView(View view, Context context, Cursor cursor) {            System.out.println("bind View");            final ContactListItemCache cache = (ContactListItemCache) view.getTag();            TextView nameView = cache.nameView;            QuickContactBadge photoView = cache.photoView;            // 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);            final String lookupKey = cursor.getString(SUMMARY_LOOKUP_KEY);            cache.photoView.assignContactUri(Contacts.getLookupUri(contactId, lookupKey));        }        @Override        public View newView(Context context, Cursor cursor, ViewGroup parent) {            System.out.println("new View");            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);            view.setTag(cache);            return view;        }    }    final static class ContactListItemCache {        public TextView nameView;        public QuickContactBadge photoView;        public CharArrayBuffer nameBuffer = new CharArrayBuffer(128);    }}

代码里最重要的是给这个view关联一个联系人的uri

cache.photoView.assignContactUri(Contacts.getLookupUri(contactId, lookupKey));
