推荐答案

请确保您有您的应用程序 READ_CONTACTS 许可。

Make sure you have READ_CONTACTS permission for your App.

    AutoCompleteTextView autoCompleteTextView = (AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);
    Cursor emailCursor = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, null, null, null);
    startManagingCursor(emailCursor);
    autoCompleteTextView.setAdapter(new SimpleCursorAdapter(this, android.R.layout.simple_dropdown_item_1line, emailCursor, new String[] {Email.DATA1}, new int[] {android.R.id.text1}));
    autoCompleteTextView.setThreshold(0);

请注意AutoCompleteTextView是区分大小写的。
