的AccountManager：如何让用户选择使用一个对话框账户 [英] AccountManager: How to let the user select an Account using a Dialog

问题描述

在的AccountManager教程记住您的用户，我们建议：

In the AccountManager tutorial Remembering Your User, it's recommended:

如果有多于一个的数组中的帐户，你应该present一个   对话框，要求用户选择之一。

If there's more than one Account in the array, you should present a dialog asking the user to select one.

什么是做到这一点的最好方法是什么？我心里有一个解决方案，但如果有来自社区其他很好的例子，它看起来这是什么样的样板code可以分享和轻松地重新被别人利用。

What's the best way to do this? I have a solution in mind, but if there are other good examples from the community, it seems like this is the kind of boilerplate code that could be shared and easily re-used by others.

推荐答案

从Android 4.0的（API级别14）日起，推出如下所示意图的活动，显示帐户选择。

From Android 4.0 (API level 14) onwards, launching an activity with an intent shown below, shows account chooser.

Intent intent = AccountManager.newChooseAccountIntent(null, null,
        new String[] { acc_type }, true, null, null,
        null, null);
startActivityForResult(intent, CHOOSE_ACCOUNT);
