问题描述
我想我所有的联系人的姓名和电话号码加载到AutoCompleteTextView的适配器。我怎样才能做到这一点？例如，当我键入G，它会显示好，＆LT; 111111>，好，＆LT; 222222>，在其下拉列表
与API的演示，我只能把DISPLAY_NAMEs在结果光标。我不知道如何既姓名和号码组合成一个光标。谢谢！
从API演示codeS：
ContentResolver的内容= getContentResolver（）;
光标光标= content.query（ContactsContract.Contacts.CONTENT_URI，
PEOPLE_PROJECTION，NULL，NULL，NULL）;
ContactListAdapter适配器=新ContactListAdapter（这一点，光标）;
mAutoCompleteTextView.setAdapter（适配器）;私有静态类ContactListAdapter CursorAdapter的扩展实现的可筛选{
私人ContentResolver的MCR; 公共ContactListAdapter（上下文的背景下，光标C）{
超（背景下，C）;
MCR = context.getContentResolver（）;
} @覆盖
公共查看NewView的（上下文的背景下，光标光标的ViewGroup父）{
最后LayoutInflater吹气= LayoutInflater.from（背景）;
最后TextView的视图=（TextView中）inflater.inflate（
android.R.layout.simple_dropdown_item_1line，父母，假）;
view.setText（cursor.getString（1））;
返回视图。
} @覆盖
公共无效bindView（查看视图，上下文的背景下，光标光标）{
（（的TextView）视图）.setText（cursor.getString（1））;
} @覆盖
公共字符串convertToString（光标光标）{
返回cursor.getString（1）;
} @覆盖
公共光标runQueryOnBackgroundThread（CharSequence的约束）{
如果（getFilterQueryProvider（）！= NULL）{
返回getFilterQueryProvider（）runQuery（约束）。
}
StringBuilder的缓冲= NULL;
字串[] args = NULL;
如果（约束！= NULL）{
缓冲区=新的StringBuilder（）;
buffer.append（UPPER（）;
buffer.append（ContactsContract.Contacts.DISPLAY_NAME）;
buffer.append（）GLOB？）;
ARGS =新的String [] {constraint.toString（）与toUpperCase（）+*};
}
返回mCR.query（ContactsContract.Contacts.CONTENT_URI，PEOPLE_PROJECTION，
缓冲== NULL？空：buffer.toString（），指定参数时，NULL）;
}
}私有静态最后的String [] = PEOPLE_PROJECTION新的String [] {
ContactsContract.Contacts._ID，
ContactsContract.Contacts.DISPLAY_NAME，
ContactsContract.Contacts.HAS_PHONE_NUMBER
};
解决方案
中的数字应该已经光标的一部分。检索它们像这样。
最终长phoneNumber的; // = c.getColumnIndex（People.NUMBER_KEY）;
if(Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) ＆GT; 0）{
ID = cursor.getString（cursor.getColumnIndex（ContactsContract.Contacts._ID））;
INT名称列= cursor.getColumnIndex（People.NAME）;
INT numberKeyColumn = cursor.getColumnIndex（People.NUMBER_KEY）;
phoneNumber的= this.getPhoneNumbers（ID）; }
然后getPhoneNumbers方法，在相同的类中，unforunately必须再次遍历。如果有一个更好的方式通过结合光标（新API）来做到这一点，但它的作品不能肯定。
众长getPhoneNumbers（字符串ID）{
长数=新龙（0）;
ContentResolver的CR = this.context.getContentResolver（）;
光标pCur = cr.query（
ContactsContract.CommonDataKinds.Phone.CONTENT_URI，
空值，
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +=？，
新的String [] {ID}，NULL）;
pCur.moveToFirst（）;
如果（pCur.getCount（）大于0）{
字符串NUM = pCur.getString（pCur.getColumnIndex（ContactsContract.CommonDataKinds.Phone.NUMBER））;
NUM = num.replaceAll（ - ，）;
数=的Long.parseLong（NUM）;
}
pCur.close（）;
返回数;
}
I want to load all of my contacts' names and phone numbers into an AutoCompleteTextView's adapter. How can I achieve that? for example, when i type "G", it will show "Good, <111111>", "Good, <222222>" in its drop-down list.
with the api demo, i can only put the DISPLAY_NAMEs in the result cursor. I don't know how to combine both names and numbers into one cursor. thanks!
codes from the api demo:
ContentResolver content = getContentResolver();
Cursor cursor = content.query(ContactsContract.Contacts.CONTENT_URI,
PEOPLE_PROJECTION, null, null, null);
ContactListAdapter adapter = new ContactListAdapter(this, cursor);
mAutoCompleteTextView.setAdapter(adapter);
private static class ContactListAdapter extends CursorAdapter implements Filterable {
private ContentResolver mCR;
public ContactListAdapter(Context context, Cursor c) {
super(context, c);
mCR = context.getContentResolver();
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
final LayoutInflater inflater = LayoutInflater.from(context);
final TextView view = (TextView) inflater.inflate(
android.R.layout.simple_dropdown_item_1line, parent, false);
view.setText(cursor.getString(1));
return view;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
((TextView) view).setText(cursor.getString(1));
}
@Override
public String convertToString(Cursor cursor) {
return cursor.getString(1);
}
@Override
public Cursor runQueryOnBackgroundThread(CharSequence constraint) {
if (getFilterQueryProvider() != null) {
return getFilterQueryProvider().runQuery(constraint);
}
StringBuilder buffer = null;
String[] args = null;
if (constraint != null) {
buffer = new StringBuilder();
buffer.append("UPPER(");
buffer.append(ContactsContract.Contacts.DISPLAY_NAME);
buffer.append(") GLOB ?");
args = new String[] { constraint.toString().toUpperCase() + "*" };
}
return mCR.query(ContactsContract.Contacts.CONTENT_URI, PEOPLE_PROJECTION,
buffer == null ? null : buffer.toString(), args, null);
}
}
private static final String[] PEOPLE_PROJECTION = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.HAS_PHONE_NUMBER
};
解决方案
The numbers should already be part of the cursor. Retrieve them like so.
final long phoneNumber;// = c.getColumnIndex(People.NUMBER_KEY);
if(Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0){
id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
int nameColumn = cursor.getColumnIndex(People.NAME);
int numberKeyColumn = cursor.getColumnIndex(People.NUMBER_KEY);
phoneNumber = this.getPhoneNumbers(id); }
Then the getPhoneNumbers method, in the same class, unforunately has to iterate again. Not sure if there's a better way to do this by binding to a cursor (in the new api), but it works.
public Long getPhoneNumbers(String id) {
Long number = new Long(0);
ContentResolver cr = this.context.getContentResolver();
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
pCur.moveToFirst();
if (pCur.getCount() > 0){
String num = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
num = num.replaceAll("-", "");
number = Long.parseLong(num);
}
pCur.close();
return number;
}
