protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
        super.onActivityResult(requestCode, resultCode, data);
        if(data!=null){enter code here
            Bundle bundle = data.getExtras();
            if(requestCode ==1){
                selectedConatcts = bundle.getStringArrayList("sel_contacts");
                Log.v("", "Selected contacts-->"+selectedConatcts);
                if(selectedConatcts.size()<0){

                    for(int i =0;i<selectedConatcts.size();i++){
                        RelativeLayout lnr_inflate = (RelativeLayout)View.inflate(thisActivity, R.layout.contacts_inflate, null);

                        // EditText edt = (EditText)lnr_inflate.findViewById(R.id.edt_contact);

                        String selectednames =selectedConatcts.get(i) ;

                        List<String> stringList = new ArrayList<String>(Arrays.asList(selectednames)); 

                        final ListView edt = (ListView)lnr_inflate.findViewById(R.id.edt_contact);

                        ArrayAdapter<String> adaptercon = new ArrayAdapter<String>(thisActivity, android.R.layout.select_dialog_multichoice,stringList);
                        edt.setAdapter(adaptercon);
                        edt.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
                        edt.setOnItemClickListener(new OnItemClickListener() {

                            @Override
                            public void onItemClick(AdapterView<?> arg0,
                                    View arg1, int arg2, long arg3) {
                                // TODO Auto-generated method stub
                                 final int len = edt.getCount();
                                    final SparseBooleanArray checked = edt.getCheckedItemPositions();

                                    for(int i =0;i<len;i++){


                                        if (checked.get(i)) {

                                            selectedConatcts.remove(phone_nos[i]);
                                            contactdisp.removeViewAt(i);


                                           //you can you this array list to next activity
//                                         do whatever you want with the checked item 
                                         }
//                                      selectedConatcts.get(i);
                                        System.out.println("i m in check button cheked"+selectedConatcts.get(i));


                                    }       
                                selectedConatcts.remove(phone_nos[arg2]);
                                contactdisp.removeViewAt(arg2);


                            }
                        });

                        contactdisp.addView(lnr_inflate);
}}}}

更好地检查复选框是否已选中或是否在button_click下编写代码
删除项目
remove selectedConatcts.remove(phone_nos[arg2]); contactdisp.removeViewAt(arg2);
