Question

我正在制作一款Android应用，我会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，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，当你点击一个电话号码时，我的平板电脑会弹出一个只显示电话号码的弹出窗口，以及一个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看到这些信息是链接的。只需显示电话号码，无论何时点击文本视图中的任何位置，都会弹出一个弹出窗口显示所有联系信息和一个选项＆＃34;添加到联系人＆＃34;，最好是

这可能吗？如果是这样，怎么样？

Answer 1

您可以使用Intents.Insert.ACTION，它将使用必需的数据调用Contacts应用程序。您需要做的就是添加所需的数据，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);

我建议你研究一下使用Gson类来有效地解析你的JSON对象。它会像，

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

Gson将映射json对象中的所有传入联系人。之后，我建议您创建一个自定义适配器，以显示您想要的联系信息。我不认为有一个模板可以显示联系人，所以你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，使用默认的联系人应用程序来显示自定义信息是不可能的，但是可以创建一个联系人并显示该联系人。所以我做的是以下几点：

我用Contact类创建了一个小型库。此联系类包含我希望联系人拥有的所有信息。在那里，我做了一个功能，检查联系人列表中是否存在提供的电子邮件地址。如果是，则此功能将启动显示联系信息的意图。否则，它将启动一个允许用户将联系人添加到其联系人列表的意图。完整的这个类看起来像这样：
