【问题描述】：

我需要显示一个自动完成文本框，它基本上会加载联系人电子邮件 ID。 我已经尝试使用自定义适配器，但文本框中没有填充任何内容。完全没有建议。任何解决方案都会非常有用。

请发布您的一些代码，以便我们更好地帮助您

阅读这篇文章***.com/questions/11879078/…这将对你有所帮助

【参考方案1】：

尝试以下方法：

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：

<uses-permission android:name="android.permission.READ_CONTACTS" />

@Korhan 肯定比我想象的要优雅得多。我的代码有效，但 @Korhan 的要简单得多。谢谢。我创建了这个自定义适配器类来读取联系人

class ContactListAdapter extends CursorAdapter implements Filterable   
        private ContentResolver mCR;

        public ContactListAdapter(Context context, Cursor c,boolean a)   
            super(context, c, true);  
            mCR = context.getContentResolver();  
        


        @Override
        public void bindView(View view, Context context, Cursor cursor) 


                 ((TextView) view).setText(cursor.getString(1));
        


        @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 String convertToString(Cursor cursor)   



            return cursor.getString(1);
        
        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.CommonDataKinds.Email.ADDRESS);
            buffer.append(") GLOB ?");
            args = new String[]  constraint.toString().toUpperCase() + "*" ;
        

        return mCR.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,CreateEventActivity.PEOPLE_PROJECTION ,buffer == null ? null : buffer.toString(), args,
               null);
        

    

还有主要的Activity：

MultiAutoCompleteTextView act = (MultiAutoCompleteTextView)findViewById(R.id.attende_list);
ContentResolver content = getContentResolver();
Cursor cursor = content.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,PEOPLE_PROJECTION, null, null, null);
ContactListAdapter adapter = new ContactListAdapter(this, cursor, true);
act.setThreshold(0);
act.setAdapter(adapter);
act.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
