Answer 1

Try this:

1) Create method checkPermissionRecordAudio()

public boolean checkPermissionRecordAudio(){
        if (ContextCompat.checkSelfPermission(this.context,
                android.Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED)
            return false;
    return true;
}

2) Create method requestPermission()

public void requestPermission(){
        if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) this.context,android.Manifest.permission.RECORD_AUDIO)) {

            AlertDialog.Builder builder = new AlertDialog.Builder(this.context);
            builder.setMessage("Enable permission record audio")
                    .setTitle("Message")
                    .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {
                            request();
                        }
                    })
                    .setNegativeButton("No", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {

                        }
                    });
            AlertDialog dialog = builder.create();
            dialog.show();
        } else {
            request();
        }
    }

3) method request()

private void richiedi(){
        ActivityCompat.requestPermissions((Activity) this.context,
                new String[]{android.Manifest.permission.RECORD_AUDIO},
                MY_PERMISSIONS_REQUEST_RECORDAUDIO);
    }

4) In the end override onRequestPermission() for handle the request

@Override
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case RequestPermission.MY_PERMISSIONS_REQUEST_RECORDAUDIO: {
                // If request is cancelled, the result arrays are empty.
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//permission is enable, do something
                } else {
                    //permission not enable
                }

            }
        }
        super.onRequestPermissionsResult(requestCode,permissions,grantResults);
    }
