To show NumberPicker in AlertDialog use this code :

final AlertDialog.Builder d = new AlertDialog.Builder(context);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.number_picker_dialog, null);
d.setTitle("Title");
d.setMessage("Message");
d.setView(dialogView);
final NumberPicker numberPicker = (NumberPicker) dialogView.findViewById(R.id.dialog_number_picker);
numberPicker.setMaxValue(50);
numberPicker.setMinValue(1);
numberPicker.setWrapSelectorWheel(false);
numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
    @Override
    public void onValueChange(NumberPicker numberPicker, int i, int i1) {
        Log.d(TAG, "onValueChange: ");
    }
});
d.setPositiveButton("Done", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
        Log.d(TAG, "onClick: " + numberPicker.getValue());
    }
});
d.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
    }
});
AlertDialog alertDialog = d.create();
alertDialog.show();
