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
     
       al;	@Override	protected void onListItemClick(ListView l, View v, int position, long id) {		// TODO Auto-generated method stub		super.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);	}	@Override	protected void onCreate(Bundle savedInstanceState) {		// TODO Auto-generated method stub		super.onCreate(savedInstanceState);		setContentView(R.layout.show_contacts);		bind();	}	public void bind() {		al = new HashMap
      
       ();		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 stub				Intent 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：

public class Sms_Send_AllActivity extends Activity {	@Override	protected void onActivityResult(int requestCode, int resultCode, Intent data) {		// TODO Auto-generated method stub		// super.onActivityResult(requestCode, resultCode, data);		if (requestCode == 0) {			if (resultCode == 1) {				Bundle bd = data.getExtras();				al = (HashMap
