高手都到哪里去了啊？

Uri uri;
                // email query
                uri = Uri.withAppendedPath(
                        ContactsContract.CommonDataKinds.Email.CONTENT_FILTER_URI,
                        Uri.encode(mKeyword));
                cursor = resolver.query(uri, EMAIL_SEARCH_PROJECTION, null, null, null);
                if (cursor != null) {
                    try {
                        while (cursor.moveToNext()) {
                            long id = cursor.getLong(ContactSummary.CONTACT_SUMMARY_COL_ID);
                            if (!excludeIds.contains(id) && !contactIds.contains(id)) {
                                contactIds.add(id);
                            }
                        }
                    } finally {
                        cursor.close();
                        cursor = null;
                    }
                }
                // phone number start to query the phone only if the number
                // looks like a phone
                if (Telephony.isPossiblePhoneNum(mKeyword)) {
                    if (Config.DEBUG) {
                        Log.v(TAG, mKeyword + " is a number");
                    }
                    uri = Uri.withAppendedPath(
                            ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI,
                            Uri.encode(mKeyword));
                    cursor = resolver.query(uri, PHONE_SEARCH_PROJECTION, null, null, null);
                    if (cursor != null) {
                        try {
                            while (cursor.moveToNext()) {
                                long id = cursor.getLong(ContactSummary.CONTACT_SUMMARY_COL_ID);
                                if (!excludeIds.contains(id) && !contactIds.contains(id)) {
                                    contactIds.add(id);
                                }
                            }
                        } finally {
                            cursor.close();
                            cursor = null;
                        }
                    }
                }

    private static final String[] EMAIL_SEARCH_PROJECTION = new String[] {
        Email.CONTACT_ID
    };
    private static final String[] PHONE_SEARCH_PROJECTION = new String[] {
        Phone.CONTACT_ID
    };

上面只搜索出 对应 email 或者 phone的 Contact_id, 然后在通过这个Contact_id 到contacts 表里面取到对应的 联系人头像。

可以参照下这个

public class MyListView2 extends Activity {
06  
07      private ListView listView;
08      //private List<String> data = new ArrayList<String>();
09      @Override
10      public void onCreate(Bundle savedInstanceState){
11          super .onCreate(savedInstanceState);
12           
13          listView = new ListView( this );
14           
15          Cursor cursor = getContentResolver().query(People.CONTENT_URI, null , null , null , null );
16          startManagingCursor(cursor);
17           
18          ListAdapter listAdapter = new SimpleCursorAdapter( this , android.R.layout.simple_expandable_list_item_1,
19                  cursor,
20                  new String[]{People.NAME},
21                  new int []{android.R.id.text1});
22           
23          listView.setAdapter(listAdapter);
24          setContentView(listView);
25      }
26       
27       
28 }
 

 

　Cursor cursor = getContentResolver().query(People.CONTENT_URI, null, null, null, null);先获得一个指向系统通讯录数据库的Cursor对象获得数据来源。

　startManagingCursor(cursor);我们将获得的Cursor对象交由Activity管理，这样Cursor的生命周期和Activity便能够自动同步，省去自己手动管理Cursor。

　SimpleCursorAdapter 构造函数前面3个参数和ArrayAdapter是一样的，最后两个参数：一个包含数据库的列的String型数组，一个包含布局文件中对应组件id的 int型数组。其作用是自动的将String型数组所表示的每一列数据映射到布局文件对应id的组件上。上面的代码，将NAME列的数据一次映射到布局文 件的id为text1的组件上。

注意：需要在AndroidManifest.xml中如权限：<uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>

有没有直接根据名字和电话写个多表查询，可以查询到photo_id的？多谢大家了。

有没有高手帮帮我啊~
