问题描述

i need to display an auto complete text box which will basically load the contacts e-mail ids. I have tried it using a custom adapter but nothing gets populated in the textbox. No suggestions at all. Any solutions will be very useful.
推荐答案
试试以下:
ArrayList<String> emailAddressCollection = new ArrayList<String>();
ContentResolver cr = getContentResolver();
Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, null, null, null);
while (emailCur.moveToNext())
{
String email = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
emailAddressCollection.add(email);
}
emailCur.close();
String[] emailAddresses = new String[emailAddressCollection.size()];
emailAddressCollection.toArray(emailAddresses);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, emailAddresses);
AutoCompleteTextView textView = (AutoCompleteTextView)findViewById(R.id.YOUR_TEXT_VIEW);
textView.setAdapter(adapter);
}
注意:不要忘记将 READ_CONTACTS
权限添加到您的 Manifest.xml:
Note: Don't forget to add the READ_CONTACTS
permission to your Manifest.xml:
<uses-permission android:name="android.permission.READ_CONTACTS" />
