You have to pass theme as well in AlertBuilder.

AlertDialog.Builder myAlert = new AlertDialog.Builder(getContext(), R.style.AppCompatAlertDialogStyle);
deleteAlert.setTitle(title);
deleteAlert.setMessage(message);
deleteAlert.setPositiveButton(android.R.string.ok, clickListener);
deleteAlert.setNegativeButton(android.R.string.cancel, clickListener);
deleteAlert.show();

No need to call the create() method if you have called show(). Because internally the show() method calls create().

Note: I can clearly say the issue from my experience. I missed to pass theme.

R.style.AppCompatAlertDialogStyle

DOES NOT WORK:

AlertDialog.Builder myAlert = new AlertDialog.Builder(getContext());

WORKS SUCCESFULLY:

AlertDialog.Builder myAlert = new AlertDialog.Builder(getContext(),  R.style.AppCompatAlertDialogStyle);

I don't know what is causing it, but for start I'm pretty sure you don't need to call builder.create() then dialog.show() separately.

Call directly builder.show() and let the Alert Dialog Builder handle its creation and display. If you really need the dialog instance, get it from the result of the builder.show().

About the lack of texts, maybe you are overriding some style, have you checked if the texts are simply White colored and because of that are "invisible"?

Instead of context, try to use ActivityName.this.
