这几天在完成《anbdroidSDK开发范例大全》中关于“搜索手机通讯录自动完成”的例子时，由于书上的例子是针对SDK1.5版本的，在用android2.2版本时，查询到的手机号为null，避免大家走弯路，特将代码贴出来共同探讨学习，由于个人能力有限，望各位大虾们指导。 创建autocontact.xml
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
android:text=""
android:id="@+id/contactACTV"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
android:id="@+id/contactTV"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
创建ContactActivity类 public class ContactActivity extends Activity{ //自动提示框
AutoCompleteTextView autoCompleteTextView;
TextView tv;
//数据库查询得到的游标
Cursor cursor;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.autocontacts);
//获得活动中的组件对象
autoCompleteTextView = (AutoCompleteTextView)findViewById(R.id.contactACTV);
tv = (TextView)findViewById(R.id.contactTV);
//查询已存在的联系人信息 并将信息绑定到autocompleteTextView中
ContentResolver cr = getContentResolver();
//制定查询字段
String[] fieldes = {ContactsContract.Contacts._ID,ContactsContract.Contacts.DISPLAY_NAME};
//获得查询的信息
cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,
fieldes, null, null, null);
while(cursor.moveToNext())
{
String[] columns = cursor.getColumnNames();
for(String s: columns)
{
String value = cursor.getString(cursor.getColumnIndexOrThrow(s));
System.out.println(s+": "+value+"\n");
}
}
//绑定自动提示框信息
ContentApdater adapter = new ContentApdater(this, cursor);
autoCompleteTextView.setAdapter(adapter);
autoCompleteTextView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView parent, View view,
int position, long id) {
//将游标定位到要显示数据的行
cursor.move(position);
String name= cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
String phone = showPhone();
String info =name+"的\n \t\t电话是："+phone;
info += "\n \t\t电子邮件："+showEmail();
tv.setText(info);
}
//显示电话号码
public String showPhone()
{
String id = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
Cursor phoneCursor = getContentResolver().query
(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID+"=?", new String[]{id}, null);
if(phoneCursor.moveToNext())
{
String phone =phoneCursor.getString(phoneCursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.DATA));
return phone;
}
phoneCursor.close();
return null;
}
//显示电子邮件
public String showEmail()
{
String id = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
Cursor emailCursor = getContentResolver().query
(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Email.CONTACT_ID+"=?", new String[]{id}, null);
if(emailCursor.moveToNext())
{
String email = emailCursor.getString(emailCursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Email.DATA));
return email;
}
return null;
}
});
}
}
class ContentApdater extends CursorAdapter{ ContentResolver resolver;
//构造函数
public ContentApdater(Context context, Cursor c) {
super(context, c);
resolver = context.getContentResolver();
} @Override //将信息绑定到控件的方法
public void bindView(View view, Context context, Cursor cursor) {
((TextView)view).setText(cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)));
}
@Override
public CharSequence convertToString(Cursor cursor) {
return cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
}
@Override //创建自动绑定选项
public View newView(Context context, Cursor cursor, ViewGroup parent) {
final LayoutInflater inflater = LayoutInflater.from(context); final TextView tv = (TextView)inflater.inflate(android.R.layout.simple_spinner_dropdown_item, parent,false);
tv.setText(cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)));
return tv;
}
} 看效果时记得在功能选项中，创建联系人（Contacts-->menu-->new contacts）
