android - 从android中的电话簿中选择多个联系人

Question

我需要从 android 的电话簿中选择联系人号码/电子邮件。

我看到从 this link 中选择一个联系人并在 onActivityResult 中返回结果.

但我需要从电话簿中选择多个联系人。如何做到这一点？

我不想制作我的自定义列表，有没有办法使用 androids 的内置功能？

 getAllContacts(this.getContentResolver());
    ListView lv = (ListView) findViewById(R.id.lv);
    ma = new MyAdapter();
    lv.setAdapter(ma);
    lv.setOnItemClickListener(this);
    lv.setItemsCanFocus(false);
    lv.setTextFilterEnabled(true);
    // adding
    select = (Button) findViewById(R.id.button1);
    select.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            StringBuilder checkedcontacts = new StringBuilder();

            for (int i = 0; i < name1.size(); i++)

            {
                if (ma.mCheckStates.get(i) == true) {
                    checkedcontacts.append(name1.get(i).toString());
                    checkedcontacts.append("\n");

                } else {

                }
