Question

I wonder if someone can help me. I’m trying to display a toast element when an SMS is received. This toast should contain a layout which has an image (SMS Icon) and 2 textviews (sender, message)

If I call the following method from an activity, it works as expected…

public void showToast(Context context, String name, String message) {
    LayoutInflater inflater = getLayoutInflater();
    View layout = inflater.inflate(R.layout.toast_sms,
                                   (ViewGroup) findViewById(R.id.toast_sms_root));

    TextView text = (TextView) layout.findViewById(R.id.toastsms_text);
    text.setText(message);

    Toast toast = new Toast(getApplicationContext());
    toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(layout);
    toast.show();
}

However, if I try to call the same code in the same way from my SMSReceiver, I get:

The method getLayoutInflater() is undefined for the type SmsReceiver
The method findViewById(int) is undefined for the type SmsReceiver
The method getApplicationContext() is undefined for the type SmsReceiver

Can someone please advise how I can do tihs from an intent. I assume the issue is somehow related to cross-threading however, I’m unsure how to proceed. I’ve seen a couple of examples online but they seem to either use deprecated code or only display simple text

Can someone please point me in the correct direction

Many thanks

You can use LayoutInflater.from(context) to get your LayoutInflater. Like this:

LayoutInflater mInflater = LayoutInflater.from(context);
View myView = mInflater.inflate(R.layout.customToast, null);
TextView sender = (TextView) myView.findViewById(R.id.sender);
TextView message = (TextView) myView.findViewById(R.id.message);
