问题描述
我想修改code，我看到的计算器一个AutoCompleteTextView，这样我会回到复式联系人进行MultiAutoCompleteTextView。
然而，当我加载此到我的Android手机我再也不能看到任何建议，以供选择。我已经觉得问题出在一个ArrayAdapter初始化，但我无法弄清楚什么是错的。
感谢您事先的任何帮助。
我有以下的code我multiautocompletetextview：
＆LT; MultiAutoCompleteTextView
机器人：ID =@ + ID / mmWhoNo
机器人：layout_width =FILL_PARENT
机器人：layout_height =WRAP_CONTENT
机器人：文字颜色=＃0000A0
机器人：提示=选择你的联系人/＆GT;
最后，我有以下阅读我的联系人我从<一个拿href=\"http://stackoverflow.com/questions/12400504/selecting-contact-from-autocomplete-textview\">selecting从自动完成的TextView 接触修改一点点。
私人的ArrayList＆LT;地图＆LT;字符串，字符串＆GT;＆GT; mPeopleList;
私人ArrayAdapter mAdapter;
私人MultiAutoCompleteTextView mTxtPhoneNo; mPeopleList =新的ArrayList＆LT;地图＆LT;字符串，字符串＆GT;＆GT;（）;
PopulatePeopleList（）;
mTxtPhoneNo =（MultiAutoCompleteTextView）findViewById（R.id.mmWhoNo）;
mTxtPhoneNo.setTokenizer（新MultiAutoCompleteTextView.CommaTokenizer（））;
mTxtPhoneNo.setThreshold（1）; //只是为了检查看到mPeopleList正在填充
Log.i（Multiplecontacts，mPeopleList.get（0）的ToString（））;
mAdapter =新ArrayAdapter＆LT; ArrayList的＆LT;地图＆LT;字符串，字符串＆GT;＆GT;＆GT;（这一点，android.R.layout.simple_dropdown_item_1line）;
mAdapter.add（mPeopleList）; mTxtPhoneNo.setAdapter（mAdapter）; mTxtPhoneNo
.setOnItemClickListener（新OnItemClickListener（）{ @覆盖

INT指数，长ARG3）{
// TODO自动生成方法存根
地图＆LT;字符串，字符串＆GT;地图=（地图＆LT;字符串，字符串＆GT;）AV
.getItemAtPosition（索引）; 字符串名称= map.get（名称）;

如果（numberType.equals（0））
NamePhoneType.put（类型，工作）;
否则如果（numberType.equals（1））
NamePhoneType.put（类型，家）;
否则如果（numberType.equals（2））
NamePhoneType.put（类型，手机）;
其他
NamePhoneType.put（类型，其他）;
//然后这个地图添加到列表中。
mPeopleList.add（NamePhoneType）;
}
phones.close（）;
}
}
people.close（）;
startManagingCursor（人）;
} }）;
解决方案
您所遇到的问题是因为您使用的是ArrayAdaptor。你给它的地图列表中选择的形式，但对如何过滤器或地图对象比较输入文本没有数据。我用了一个SimpleAdapter，而不是和它工作得很好。
mTxtPhoneNo =（MultiAutoCompleteTextView）findViewById（R.id.multiAutoCompleteTextViewContactsNames）;
mAdapter =新SimpleAdapter（这一点，mPeopleList，R.layout.costom_contact_view，新的String [] {姓名，手机，类型}，新的INT [] {
R.id.ccontName，R.id.ccontNo，R.id.ccontType}）;
mTxtPhoneNo.setThreshold（1）;
mTxtPhoneNo.setAdapter（mAdapter）;
mTxtPhoneNo.setTokenizer（新MultiAutoCompleteTextView.CommaTokenizer（））;
mTxtPhoneNo.setOnItemClickListener（multiAutoContactNamesListener）;
此外，你OnClickListener一定要串连联系人的姓名。
变化：
mTxtPhoneNo.setText（+姓名+＆LT;+数字+＆gt;中）;
要：
mTxtPhoneNo.append（，+名字+＆LT;+数字+＆gt;中）;
希望这有助于。
I am trying to modify a code that I have seen on stackoverflow for an AutoCompleteTextView so that i would return mutliple contacts for a MultiAutoCompleteTextView.
However, when I load this onto my Android phone I can no longer see any suggestions to select from. I have feeling that the problem lies in the ArrayAdapter initialization but I cannot figure out what is wrong with it.
Thanks in advance for any help.
I have the following code for my multiautocompletetextview:
<MultiAutoCompleteTextView
android:id="@+id/mmWhoNo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#0000A0"
android:hint="Choose your Contacts" />
And finally I have the following to read my contacts which i have take from selecting contact from autocomplete textview with a little bit of modification.
private ArrayList<Map<String, String>> mPeopleList;
private ArrayAdapter mAdapter;
private MultiAutoCompleteTextView mTxtPhoneNo;
mPeopleList = new ArrayList<Map<String, String>>();
PopulatePeopleList();
mTxtPhoneNo = (MultiAutoCompleteTextView) findViewById(R.id.mmWhoNo);
mTxtPhoneNo.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
mTxtPhoneNo.setThreshold(1);
//just to check to see that mPeopleList is being populated
Log.i("Multiplecontacts",mPeopleList.get(0).toString());
mAdapter = new ArrayAdapter<ArrayList<Map<String,String>>>(this, android.R.layout.simple_dropdown_item_1line);
mAdapter.add(mPeopleList);
mTxtPhoneNo.setAdapter(mAdapter);
mTxtPhoneNo
.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> av, View arg1,
int index, long arg3) {
// TODO Auto-generated method stub
Map<String, String> map = (Map<String, String>) av
.getItemAtPosition(index);
String name = map.get("Name");
String number = map.get("Phone");
mTxtPhoneNo.setText("" + name + "<" + number + ">,");
}
public void PopulatePeopleList() {
mPeopleList.clear();
Cursor people = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (people.moveToNext()) {
String contactName = people.getString(people
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String contactId = people.getString(people
.getColumnIndex(ContactsContract.Contacts._ID));
String hasPhone = people
.getString(people
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if ((Integer.parseInt(hasPhone) > 0)) {
// You know have the number so now query it like this
Cursor phones = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = " + contactId, null, null);
while (phones.moveToNext()) {
// store numbers and display a dialog letting the user
// select which.
String phoneNumber = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String numberType = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
Map<String, String> NamePhoneType = new HashMap<String, String>();
NamePhoneType.put("Name", contactName);
NamePhoneType.put("Phone", phoneNumber);
if (numberType.equals("0"))
NamePhoneType.put("Type", "Work");
else if (numberType.equals("1"))
NamePhoneType.put("Type", "Home");
else if (numberType.equals("2"))
NamePhoneType.put("Type", "Mobile");
else
NamePhoneType.put("Type", "Other");
// Then add this map to the list.
mPeopleList.add(NamePhoneType);
}
phones.close();
}
}
people.close();
startManagingCursor(people);
}
});
解决方案
The problem you are having is because you are using an ArrayAdaptor. You are giving it a list of Map to choose form but no data on how to filter or compare the map objects to the input text. I used a SimpleAdapter instead and it worked fine.
mTxtPhoneNo = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextViewContactsNames);
mAdapter = new SimpleAdapter(this, mPeopleList, R.layout.costom_contact_view, new String[] { "Name", "Phone", "Type" }, new int[] {
R.id.ccontName, R.id.ccontNo, R.id.ccontType });
mTxtPhoneNo.setThreshold(1);
mTxtPhoneNo.setAdapter(mAdapter);
mTxtPhoneNo.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
mTxtPhoneNo.setOnItemClickListener(multiAutoContactNamesListener);
Also, in you OnClickListener be sure to concatenate the contacts' names. Change :
mTxtPhoneNo.setText("" + name + "<" + number + ">,");
To:
mTxtPhoneNo.append(", " + name + " <" + number + ">");
Hope this helps.
