我使用下面的代码，它可以正常工作。它在通话结束后返回。

Uri number = Uri.parse("tel:" + contactNumber);
Intent dial = new Intent(Intent.ACTION_CALL, number);
if (ActivityCompat.checkSelfPermission(mContext, android.Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                                // TODO: Consider calling
                                //    ActivityCompat#requestPermissions
                                // here to request the missing permissions, and then overriding
                                //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                                //                                          int[] grantResults)
                                // to handle the case where the user grants the permission. See the documentation
                                // for ActivityCompat#requestPermissions for more details.
     return;
}
mContext.startActivity(dial);

尝试使用它，如果它适合你。
