直奔主题~！

结构如图：

person_content.java代码：

public class person_content extends ListActivity {private Button submit_result_btn;private HashMap<String, String> al;@Overrideprotected void onListItemClick(ListView l, View v, int position, long id) {// TODO Auto-generated method stubsuper.onListItemClick(l, v, position, id);CheckBox cb = (CheckBox) v.findViewById(R.id.cb);TextView username_txt = (TextView) v.findViewById(R.id.username);TextView phonenum_txt = (TextView) v.findViewById(R.id.tel_num);String username = username_txt.getText().toString();String phonenum = phonenum_txt.getText().toString();cb.setEnabled(true);if (cb.isChecked()) {cb.setChecked(false);al.remove(phonenum);} else {cb.setChecked(true);al.put(phonenum, username);}cb.setEnabled(false);}@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.show_contacts);bind();}public void bind() {al = new HashMap<String, String>();submit_result_btn = (Button) this.findViewById(R.id.submit_result_btn);Cursor ps_cs = getContentResolver().query(People.CONTENT_URI, null,null, null, null);startManagingCursor(ps_cs);String[] string = { Phones.NAME, Phones.NUMBER };int[] intText = { R.id.username, R.id.tel_num };SimpleCursorAdapter sca = new SimpleCursorAdapter(person_content.this,R.layout.person_content, ps_cs, string, intText);setListAdapter(sca);submit_result_btn.setOnClickListener(new OnClickListener() {public void onClick(View v) {// TODO Auto-generated method stubIntent it = new Intent();Bundle bd = new Bundle();bd.putSerializable("select_people", al);it.putExtras(bd);setResult(1, it);finish();}});}}

Sms_Send_AllActivity.java代码：
