对AutoCompleteTextView添加text变化的监听函数：

   mAutoCompleteTextView.addTextChangedListener(new TextWatcher(){

           @Override
           public void afterTextChanged(Editable s) {
               // TODO Auto-generated method stub

           }

           @Override
           public void beforeTextChanged(CharSequence s, int start, int count,
                   int after) {
               // TODO Auto-generated method stub

           }

           @Override
           public void onTextChanged(CharSequence s, int start, int before,
                   int count) {
               // TODO Auto-generated method stub
               if(s.toString().length()>0){
                   /**电话本列表背景置灰切不可点击。*/

                   m_list_frame_book.setEnabled(false);
                    m_list_frame_book.setBackgroundColor(0x7DC0C0C0);
               }else{
                   /**点击后是listview的灰显消失，listview也可以点击。*/

                   m_list_frame_book.setEnabled(true);
                    m_list_frame_book.setBackgroundDrawable(null);
               }
               String mSearchaContactName = s.toString().trim();
               Cursor cursor = DBHelper.QueryContact(mSearchaContactName);
               //startManagingCursor(cursor);
               SearchCurAdapter adapter = new SearchCurAdapter(CarBTActivity.this,cursor,true);
               mSearchPhoneBook.setAdapter(adapter);

           }

          });

对AutoCompleteTextView下来框添加点击事件处理：

mAutoCompleteTextView.setOnItemClickListener(searchItemClick);

        /**
       * 搜索联系人下拉框点击事件
       */
      OnItemClickListener searchItemClick=new OnItemClickListener(){

           @Override
           public void onItemClick(AdapterView<?> av, View v, int position,
                   long l) {
               // TODO Auto-generated method stub
               m_show_mode=7;
               changeBTFrameShow();
               changeBottomBnFocus(R.id.id_bn_keyboard);
               //View mView = av.getChildAt(position);
                TextView tvName= (TextView) v.findViewById(R.id.search_connact_name);
                TextView tvNum=(TextView)v.findViewById(R.id.search_connact_num);
               String selectName=tvName.getText().toString();
               String selectNum=tvNum.getText().toString();

               Message localMessage = new Message();
               localMessage.obj = selectNum;
               localMessage.what = BTSdevice.OPER_BTORDERDIAL;
               if (mBTActionHandle.hasMessages(BTSdevice.OPER_BTORDERDIAL)){
                   mBTActionHandle.removeMessages(BTSdevice.OPER_BTORDERDIAL, selectNum);
                }

               mBTActionHandle.sendMessageDelayed(localMessage, 1000L);
               connecting_keyboard_phone_num.setText(selectNum);
               m_talking_keyboard_phone_num_d.setText(selectNum);
               m_talking_keyboard_phone_num.setText(selectNum);
               connecting_keyboard_phone_name.setText(selectName);
               m_talking_keyboard_phone_name_d.setText(selectName);
               m_talking_keyboard_phone_name.setText(selectName);
               m_handle_talking.sendEmptyMessageDelayed(0, 10000L);
               //int position=0;
               Log.v(TAG,"==========>item click in");

               mSearchPhoneBook.setText(null);
               mSearchPhoneMiss.setText(null);
               mSearchPhoneIn.setText(null);
               mSearchPhoneOut.setText(null);

               /**点击后是listview的灰显消失，listview也可以点击。*/

               m_list_frame_book.setEnabled(true);
                m_list_frame_book.setBackgroundDrawable(null);


           }

      };
