White on white text inside dialogue box

Question

Hi guys I searched through other titles relating to white on white text but they do not help me as I encounter this issue when forgot password has been clicked. As you can see all other fields within the dialogue box seem to appear as they should, however my cancel, and recover buttons are unseen until clicked and a very light grey box forms around the buttons.

I have tried to use setTitle(androidcolor.R.black)inside the code but it didnt work haha. I am learning slowly and this may very well be an easy fix but it evades me for now.

This is the code I have run with it hopefully it helps someone help me or at least point me to the right place :)

 private void showRecoverPasswordDialog() {
    //AlertDialog
    AlertDialog.Builder builder =  new AlertDialog.Builder(this);
    builder.setTitle("Recover Password");

    //Set Layout to Linear Layout
    LinearLayout linearLayout = new LinearLayout(this);

    //Views to set in Dialog
    final EditText emailET = new EditText(this);
    emailET.setHint("Email");
    emailET.setInputType(InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS);

    emailET.setMinEms(16);

    linearLayout.addView(emailET);
    linearLayout.setPadding(10,10,10,10);

    builder.setView(linearLayout);

    //Button to Recover
    builder.setPositiveButton("Recover", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            //Input Email for Recovery
            String email = emailET.getText().toString().trim();
            beginRecovery(email);
        }
    });
    //Button to Cancel
    builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            //Dismiss Dialog
            dialog.dismiss();
        }
    });

    //Show Dialog
    builder.create().show();

}

private void beginRecovery(String email) {
    //Show progress dialog
    progress_Dialog.setMessage("Recovery Email sending...");
    progress_Dialog.show();
    mAuth.sendPasswordResetEmail(email).addOnCompleteListener(new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            progress_Dialog.dismiss();
            if(task.isSuccessful()){
                Toast.makeText(LoginActivity.this, "Recovery Email has been sent", Toast.LENGTH_SHORT).show();
            }
            else{
                Toast.makeText(LoginActivity.this, "Recovery Email failed to send ", Toast.LENGTH_SHORT).show();
            }
        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            progress_Dialog.dismiss();
            //Get and Show proper Error Message
            Toast.makeText(LoginActivity.this, ""+e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });
}

private void loginUser(String email, String passw) {
    //Show progress dialog
    progress_Dialog.setMessage("Logging in...");
    progress_Dialog.show();
    mAuth.signInWithEmailAndPassword(email, passw)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        //Dismiss progress dialog
                        progress_Dialog.dismiss();
                        // Sign in success, update UI with the signed-in user's information
                        FirebaseUser user = mAuth.getCurrentUser();
                        //User is logged in, start Login Activity
                        startActivity(new Intent(LoginActivity.this, ProfileActivity.class));
                        finish();
                    } else {
                        //Dismiss progress dialog
                        progress_Dialog.dismiss();
                        // If sign in fails, display a message to the user.
                        Toast.makeText(LoginActivity.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                    }
                }
            }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            //Dismiss progress dialog
            progress_Dialog.dismiss();
            //Get and show an Error Message
            Toast.makeText(LoginActivity.this, ""+e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });
