[经验分享] Android实现多选联系人
有很多网友问多选联系人实现方式，这里参考了apidemos的例子做了简单实现。整体思路是使用使用一个ArrayList存放选中的联系人信息，细节就不说了，贴一下代码
public
class CopyContactsListMultiple extends ListActivity implements OnClickListener{
private
final
int UPDATE_LIST=1; ArrayList contactsList; //得到的所有联系人
ArrayList getcontactsList; //选择得到联系人
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(); getcontactsList=new ArrayList();
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(this, android.R.layout.simple_list_item_multiple_choice, contactsList));
}
@Override
protected
void onListItemClick(ListView l, View v, int position, long id) { // TODO Auto-generated method stub
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(“[")>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
public
void run() { // TODO Auto-generated method stub
Uri uri = ContactsContract.Contacts.CONTENT_URI; String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.PHOTO_ID }; String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + “ = ’1′”; String[] selectionArgs = null; String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + “ COLLATE LOCALIZED ASC”; Cursor cursor=managedQuery(uri, projection, selection, selectionArgs, sortOrder); Cursor phonecur = null;
while (cursor.moveToNext()){
// 取得联系人名字
int nameFieldColumnIndex = cursor.getColumnIndex(android.provider.ContactsContract.PhoneLookup.DISPLAY_NAME); String name = cursor.getString(nameFieldColumnIndex);
// 取得联系人ID
String contactId = cursor.getString(cursor.getColumnIndex(android.provider.ContactsContract.Contacts._ID)); phonecur = managedQuery(android.provider.ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, android.provider.ContactsContract.CommonDataKinds.Phone.CONTACT_ID + “ = ” + contactId, null, null); // 取得电话号码(可能存在多个号码) while (phonecur.moveToNext()){ String strPhoneNumber = phonecur.getString(phonecur.getColumnIndex(android.provider.ContactsContract.CommonDataKinds.Phone.NUMBER)); if(strPhoneNumber.length()>4) contactsList.add(“18610011001″+“\n测试”); //contactsList.add(strPhoneNumber+”\n”+name+”");
} } if(phonecur!=null) phonecur.close(); cursor.close();
Message msg1=new Message(); msg1.what=UPDATE_LIST; updateListHandler.sendMessage(msg1); } } @Override protected void onPause() { // TODO Auto-generated method stub super.onPause();
}
@Override protected void onDestroy() { contactsList.clear(); getcontactsList.clear(); super.onDestroy(); }
@Override public void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.contacts_done_button: Intent i = new Intent(); if(getcontactsList!=null>>getcontactsList.size()>0){ Bundle b = new Bundle(); b.putStringArrayList(“GET_CONTACT”, getcontactsList); i.putExtras(b); } setResult(RESULT_OK, i); CopyContactsListMultiple.this.finish(); break; case R.id.contact_back_button: CopyContactsListMultiple.this.finish(); break; default: break; } } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // TODO Auto-generated method stub if(keyCode==KeyEvent.KEYCODE_BACK){ Intent i = new Intent(); Bundle b = new Bundle(); b.putStringArrayList(“GET_CONTACT”, getcontactsList); i.putExtras(b); // } setResult(RESULT_OK, i); } return super.onKeyDown(keyCode, event); }
