Get only digits from input and call that number Android

问题

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.

For example when the user says: bel 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;
}

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

回答1:

You need to get numbers from String like this:

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

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);

Hope this helps.

Can you try this

Intent.ACTION_CALL

and make sure that you are using this before application tag in manifest file

<uses-permission android:name="android.permission.CALL_PHONE" />

回答3:

You can use regex and delete non-digits.

str = str.replaceAll("\\D+","");

回答4:

Try this one..

   Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + yours_numbers_values));
   startActivity(intent);

回答5:

    String one = "bel";
String mostLikelyThingHeard="bel 0612345678";
if (mostLikelyThingHeard.contains(one)) {
    String numbers = mostLikelyThingHeard.replaceAll("[^0-9]", "");
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:"+Uri.encode(numbers.trim())));
    startActivity(callIntent);
    tts.speak(numbers + " wordt gebeld.",
    TextToSpeech.QUEUE_FLUSH, null);
    found = true;
}

And in Manifest add permission

<uses-permission android:name="android.permission.CALL_PHONE" ></uses-permission>
