从输入得到的只是数字并拨打该号码的Andr​​oid [英] Get only digits from input and call that number Android

问题描述

好吧，我创建Android应用程序，我不喜欢让从这里输入数 mostLikelyThingHeard unfortenately我的code没有出于某种原因

Okay, I am creating an android app, I do like to get the number from an input here mostLikelyThingHeard unfortenately my code doesn't work for some reason.

例如，当用户说：BEL 0612345678

For example when the user says: bel 0612345678

拨号器必须调用0612345678

The dialer has to call 0612345678

String one = "bel";
if (mostLikelyThingHeard.contains(one)) {
    String numbers = mostLikelyThingHeard.replaceAll("[^0-9]", "");
    Intent call = new Intent(Intent.ACTION_DIAL);
    call.setData(Uri.parse("tel:" + numbers));
    tts.speak(numbers + " wordt gebeld.",
    TextToSpeech.QUEUE_FLUSH, null);
    found = true;
}

我还添加了在AndroidManifest.xml正确的权限，我猜code是错误的。

I also added the right permissions in AndroidManifest.xml, I guess the code is wrong.

推荐答案

您需要从字符串得到的数字是这样的：

You need to get numbers from String like this:

String numbers = mostLikelyThingHeard.replaceAll("[^\\d]", "");

要拨打该号码，就可以使用ACTION_CALL。 ACTION_DIAL将只需打开拨号屏幕，这个数字。此外，你已经初始化的意图，但你缺少调用 startActivity（意向）

To call that number, you can use ACTION_CALL. ACTION_DIAL will just open a dialer screen with that number. Also, you have initialized intent, but you are missing call to startActivity(intent)

Intent call = new Intent(Intent.ACTION_DIAL);
call.setData(Uri.parse("tel:" + numbers));
startActivity(call);

希望这有助于。
