我怎样才能显示一个CALL采用的是Android处理之前作出选择对话框？ [英] How can I display a dialog box for making a choice before a CALL is processed in android?

问题描述

我想拦截外拨电话，并将其传递给VoIP应用。我看到，谷歌语音应用程序的每个调用实际启动之前显示问题的功能。它为用户提供了选择

I would like to intercept outgoing calls and pass them to a VOIP application. I see that the Google Voice application has a feature for displaying a question before each call is actually initiated. It provides the user with the choice:

• 通过谷歌语音启动呼叫


• 启动通过标准的呼叫通话

我想办法做到我的申请类似的东西（所以，并非所有的呼叫都通过它进行路由）。此刻，我可以通过一个BroadcastReceiver拦截呼叫事件，但是，这些都不允许打开对话框（从而能够以显示的选择）。

I would like a way to do something similar with my application (so that not all calls have to be routed through it). At the moment, I can intercept CALL events via a BroadcastReceiver, however, these are not allowed to open dialogs (thus making it possible to display the choice).

什么是实现这一目标的最佳途径？

What is the best way of achieving this goal?

推荐答案

您的应用程序应该监听的意图：NEW_OUTGOING_CALL

Your application should listen for the intent : NEW_OUTGOING_CALL

检查此处的http://developer.android.com/reference/android/content/Intent.html#ACTION_NEW_OUTGOING_CALL

一旦你收到的意图在BroadcaseReceiver，与你的活动类的意图从而显示的对话框打电话给你的活动通过它。

And once you receive the intent in a BroadcaseReceiver, call your activity through it with your activity class intent which in turn displays the dialog.
