推荐答案

根据API，ACTION_CALL会做你的需要，但不紧急号码，而ACTION_DIAL将显示与拨号提示拨号器，但允许拨打紧急电话号码。

According to the API, ACTION_CALL will do what you need but not to emergency numbers, while ACTION_DIAL will display a dialer with the dial prompt but allows to call emergency numbers.

恐怕是没有办法做你想做的，一个很好的理由 - 以prevent拨错紧急服务。这是一个precautionary措施。

I'm afraid there is no way to do what you want, for a good reason - to prevent misdials to emergency services. It's a precautionary measure.
