A reusable dialer implementation extracted from AOSP.

repositories {
    jcenter()
}
compile 'im.dlg:android-dialer:1.2.3'

Just add the DialpadFragment into your activity and make sure the activity implements DialpadActivity.Callback:

interface Callback {
    void ok(String formatted, String raw);
}

The formatted string contains the input as it displayed to user (+1 555-546-0001) and the raw string contains characters only (+15555460001).

Intent intent = new Intent(context, DialpadActivity.class);
startActivityForResult(intent, 100); // any result request code is ok

And then in your onActivityResult:

@Override
override void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == Activity.RESULT_OK) {
        String formatted = data.getStringExtra(DialpadActivity.EXTRA_RESULT_FORMATTED);
        String raw = data.getStringExtra(DialpadActivity.EXTRA_RESULT_RAW);
        ...
    }
}

Whether you're using a fragment or an activity, you can provide configuration via extras. For a fragment use setArguments, and for activity use intent extras.

Arguments are:

1. EXTRA_REGION_CODE (string): Region code for the phone formatter. Default is US.
2. EXTRA_FORMAT_AS_YOU_TYPE (boolean): Enable phone formatting. If disabled, both formatted and raw results will be the same. Default is true.
3. EXTRA_ENABLE_STAR (boolean): Will show the 'star' symbol. Default is true.
4. EXTRA_ENABLE_POUND (boolean): Will show the 'pound' symbol. Default is true.
5. EXTRA_ENABLE_PLUS (boolean): Will show the 'plus' symbol. Default is true.
6. EXTRA_CURSOR_VISIBLE (boolean): Will show the cursor in the digits EditText. Default is true.

The dialer is styled using android theme colors; the button color is colorAccent and digits color is colorPrimary.
