Android 如果没有课堂活动的扩展，如何获取电子邮件id'；从contacts获取s并从contacts获取电话号码？
大家好，如何实现从联系人处获取电子邮件id和从联系人处获取电话号码的编码告诉我克服此问题的方法Android 如果没有课堂活动的扩展，如何获取电子邮件id'；从contacts获取s并从contacts获取电话号码？,android,Android,大家好，如何实现从联系人处获取电子邮件id和从联系人处获取电话号码的编码告诉我克服此问题的方法 注意：类没有extends活动和oncreate（）方法，所以请帮助我继续看看这段代码 btn_existing_contacts.setOnClickListener(new OnClickListener() { public void onClick(View v){ Intent intent_contacts = new Intent(Intent.A

Send_investments.class是我使用这些联系人的活动您的类没有extends activity或onCreate（）方法。因此，从将活动扩展到此类的类中传递上下文参数 sudo代码 在这里，B类不扩展活动。 但是将以下方法写入类别B中的gwt联系人和电子邮件id

当您将从活动创建该类的对象时，请将此作为参数传递给类如何实现ApplicationConstants.phoneContacts.add（新ContactNumberBean（ContactName of Contact，contactNumber，contactNumberType））请给我解决此问题的方法Hi deepak我正在添加评论请编辑您的答案/如何实现ApplicationConstants和ContactEmailBean…这就是这里的问题。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。添加（新的ContactEmailBean（contactName，emailIdOfContact，emailType））；嗨，迪帕克，请提出一些建议，我在更多的日子里感到震惊谢谢拉克斯曼，我已经编辑了我的答案。现在看看，它会对你有用的。昨天我离开办公室，这就是为什么我不能给你答案Hi deepak这个两个bean类还可以如何检索classA活动类中的联系人总数公共类通讯簿扩展活动{@Override public void onCreate（Bundle savedInstanceState）{super.onCreate（savedInstanceState）；setContentView（R.layout.main）；ContactList1.getContactEmails（此）；ContactList1.GetContactNumber（此）；}
