Android ProgressDialog setMessage from string Resources

Issue

I have this code

    public void serviceUnavailable() {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {

            progressBar = new ProgressDialog(context);
            progressBar.setOnKeyListener(new DialogInterface.OnKeyListener() {
                @Override
                public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
                    if (keyCode == KeyEvent.KEYCODE_BACK) {
                        atsSocketManager.disconnect();
                        progressBar.dismiss();
                    }
                    return false;
                }
            });
            progressBar.setCancelable(false);
            progressBar.setTitle(R.string.ats_title_wait);
            progressBar.setMessage(R.string.ats_unavailable_service);
            progressBar.setProgressStyle(ProgressDialog.STYLE_SPINNER);
            progressBar.show();
        }
    });
}

But I am getting an error on line where I am setting the message if I set like this

progressBar.setMessage(R.string.ats_unavailable_service);

The error is this

error: no suitable method found for setMessage(int) method ProgressDialog.setMessage(CharSequence) is not applicable (actual argument int cannot be converted to CharSequence by method invocation conversion) method AlertDialog.setMessage(CharSequence) is not applicable (actual argument int cannot be converted to CharSequence by method invocation conversion)

where I set the title is almost the same and is working

progressBar.setTitle(R.string.ats_title_wait);

If I put the text between comas is working, but I want to understand why this way doesn't work

progressBar.setMessage("Service unavailable");

thank you

Solution

Yes, Because setMessage() is not designed to get resource string as int.

You have to get String from resource int and apply to setMessage() using getResource().getString() method of Application Context.

Like,

progressBar.setMessage(context.getResources().getString(R.string.ats_unavailable_service));
