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" />
