您可以从联系人列表中获取所有联系人并将其显示在列表中。您可以使用复选框选择联系人并单击按钮。导航到 SendMessage 活动并输入短信内容并发送消息
我认为有更好的方法来处理复选框。对于复选框获取所选项目，我点击以下链接。
https://groups.google.com/forum/?fromgroups#!topic/android-developers/No0LrgJ6q2M
您还可以获取您只需要的列。下面获取所有不好的列。
Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);

你需要添加这两个权限
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.SEND_SMS" />
编辑：
首先打开 SendMessage 活动。单击editext1 旁边的获取按钮。导航到显示所有联系人的 MainActivity 并使用复选框进行选择。单击发送将完成活动并返回短信活动。在editext 1中可以看到选中的联系人，其余的都一样。
我使用 startActivity 作为结果。这比我能做的更多。请相应修改。
