正确显示联系信息

Question

我正在制作一个 Android 应用，在其中显示联系信息。此信息来自 webAPI，采用 JSON 格式。我得到的是一堆字符串，比如名字、姓氏、电话号码等。

目前我有这样的设置：

JSONObject object = array.getJSONObject(0);
TextView contact = (TextView) view.findViewById(R.id.contact);
String contactString = "";
contactString += object.getString("Voorletters") + " ";
contactString += object.getString("Voorvoegsel").trim() + " ";
contactString += object.getString("Achternaam") + "\n";
contactString += object.getString("Email")+"\n";
if (!object.getString("Mobiel").isEmpty()) {
    contactString += object.getString("Mobiel") + "\n";
}
if (!object.getString("Mobiel2").isEmpty()) {
    contactString += object.getString("Mobiel2") + "\n";
}
if (!object.getString("Telefoon").isEmpty()) {
    contactString += object.getString("Telefoon") + "\n";
}
if (!object.getString("Telefoon2").isEmpty()) {
    contactString += object.getString("Telefoon2") + "\n";
}
contact.setText(contactString);
Linkify.addLinks(contact,Linkify.ALL);

这很好用，你可以点击电子邮件和电话号码就好了。我唯一的问题是，当您点击一个电话号码时，我的平板电脑会弹出一个仅显示电话号码的窗口，并提供将该电话号码添加到联系人列表的选项。

我想要实现的是让 android 看到这个信息是链接的。这不仅仅是显示电话号码，每当您点击文本视图中的任何位置时，都会弹出一个显示所有联系信息和“添加到联系人”选项的弹出窗口，最好像

这可能吗？如果有，怎么做？

Answer 1

您可以使用 Intents.Insert.ACTION 调用带有必要数据的联系人应用程序。您需要做的就是添加所需的数据，例如电话号码、电子邮件等作为额外的意图。

// Creates a new Intent to insert a contact
Intent intent = new Intent(Intents.Insert.ACTION);
// Sets the MIME type to match the Contacts Provider
intent.setType(ContactsContract.RawContacts.CONTENT_TYPE);

// Inserts a name
intent.putExtra(Intents.Insert.NAME, name);

// Inserts an email address
intent.putExtra(Intents.Insert.EMAIL, mEmailAddress.getText());

startActivity(intent);

我建议您考虑使用 Gson 类来有​​效地解析您的 JSON 对象。它会像，

Gson gson = new Gson();
JSONObject object = array.getJSONObject(0);    
ContactClass person = gson.fromJson((String)object, ContactClass.class); 

Gson 将从 json 对象映射所有传入的联系人。 之后，我建议您创建一个自定义适配器来显示您想要的联系信息。 我认为没有显示联系人的模板，因此您必须创建自己的适配器和 xml 视图。

感谢 iago，我设法找到了解决方案。显然不可能使用默认的联系人应用程序来显示自定义信息，但可以创建一个联系人并显示该联系人。所以我所做的如下：

我创建了一个带有 Contact 类的小型库。这个联系人类包含我希望我的联系人拥有的所有信息。在那里，我创建了一个函数来检查提供的电子邮件地址是否存在于联系人列表中。如果是这样，此函数将启动一个显示联系人信息的意图。否则，它将启动一个意图，允许用户将联系人添加到他们的联系人列表中。完整的这个类看起来像这样：
