android多選聯系人實作

有很多網友問多選聯系人實作方式，這裡參考了apidemos的例子做了簡單實作。

<a href="http://blog.51cto.com/attachment/201203/224551404.gif" target="_blank"></a>

整體思路是使用使用一個ArrayList存放選中的聯系人資訊，細節就不說了，貼一下代碼

public class CopyContactsListMultiple extends ListActivity implements OnClickListener{  

    private final int UPDATE_LIST=1;  

    ArrayList&lt;String&gt; contactsList; //得到的所有聯系人  

    ArrayList&lt;String&gt; getcontactsList; //選擇得到聯系人  

    private Button okbtn;  

    private Button cancelbtn;  

    private ProgressDialog proDialog;  

    Thread getcontacts;  

    Handler updateListHandler = new Handler() {  

            public void handleMessage(Message msg) {  

                 switch (msg.what) {  

                 case UPDATE_LIST:  

                     if (proDialog != null) {  

                            proDialog.dismiss();  

                        }  

                     updateList();   

                 }  

            }  

     };  

    public void onCreate(Bundle savedInstanceState) {  

        super.onCreate(savedInstanceState);  

        setContentView(R.layout.contactslist);  

        contactsList=new ArrayList&lt;String&gt;();  

        getcontactsList=new ArrayList&lt;String&gt;();  

        final ListView listView = getListView();  

        listView.setItemsCanFocus(false);  

        listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);  

        okbtn=(Button)findViewById(R.id.contacts_done_button);  

        cancelbtn=(Button)findViewById(R.id.contact_back_button);  

        okbtn.setOnClickListener(this);  

        cancelbtn.setOnClickListener(this);  

        getcontacts=new Thread(new GetContacts());  

        getcontacts.start();  

        proDialog = ProgressDialog.show(CopyContactsListMultiple.this, "loading","loading", true, true);  

    }  

    @Override 

    protected void onResume() {  

        // TODO Auto-generated method stub  

        super.onResume();  

    void updateList(){  

        if(contactsList!=null)  

        setListAdapter(new ArrayAdapter&lt;String&gt;(this,  

               android.R.layout.simple_list_item_multiple_choice, contactsList));  

    protected void onListItemClick(ListView l, View v, int position, long id) {  

        if(!((CheckedTextView)v).isChecked()){  

            CharSequence num=((CheckedTextView)v).getText();  

            getcontactsList.add(num.toString());  

        }  

            if(((CheckedTextView)v).isChecked()){     

                CharSequence num=((CheckedTextView)v).getText();  

                if((num.toString()).indexOf("[")&gt;0){  

                    String phoneNum=num.toString().substring(0, (num.toString()).indexOf("\n"));  

                    getcontactsList.remove(phoneNum);  

                    Log.d("remove_num", ""+phoneNum);  

                    }else{  

                         getcontactsList.remove(num.toString());  

                        Log.d("remove_num", ""+num.toString());  

                    }  

        super.onListItemClick(l, v, position, id);    

   class GetContacts implements Runnable{  

       @Override

            Cursor cursor=managedQuery(uri, projection, selection, selectionArgs, sortOrder);  

            Cursor phonecur = null;  

            while (cursor.moveToNext()){    

                // 取得聯系人名字    

                int nameFieldColumnIndex = cursor.getColumnIndex(android.provider.ContactsContract.PhoneLookup.DISPLAY_NAME);    

                String name = cursor.getString(nameFieldColumnIndex);

                }      

            }    

            if(phonecur!=null)  

             phonecur.close();  

            cursor.close();   

            Message msg1=new Message();
