How can reload the 0 page ?

Question

Hi treehousers! I have stuck! I need to reload the 0 page when articles of the app has been to the end and to hide the previous Button only when the app shows my first article ( 0 page). Because there is no need the user see the previous button when he can't choose it. Thanks for any help.

public class StoryActivity extends AppCompatActivity {

public static final String TAG = StoryActivity.class.getSimpleName();


private Story mStory = new Story();

private ImageView mImageView;
private TextView mTextView;
private Page mCurrentPage;
private String mName;
private Button mPreviousButton;
private Button mNextButton;
private ScrollView mScrollView;
private Button mStartButton;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_story2);

  //Intent intent = getIntent();
   //mName = intent.getStringExtra(getString(R.string.key_name));

    if(mName == null){
        mName = "";
    }

    Log.d(TAG, mName);

    mImageView = (ImageView)findViewById(R.id.storyImageView);
    mTextView = (TextView)findViewById(R.id.storyTextView);
   mPreviousButton = (Button)findViewById(R.id.previousButton);
   mNextButton = (Button)findViewById(R.id.nextButton);

    mTextView.setMovementMethod(new ScrollingMovementMethod());

    loadPage(0);
}
private void loadPage(int choice){
 mCurrentPage = mStory.getPage(choice);

    Drawable drawable  = getResources().getDrawable(mCurrentPage.getImageId());
    mImageView.setImageDrawable(drawable);

    String pageText = mCurrentPage.getText();
    //add the name if placeholder included.
   //pageText  = String.format(pageText,mName);
    mTextView.setText(pageText);

    if(mCurrentPage.isSingle()){
        mPreviousButton.setVisibility(View.VISIBLE);
        mNextButton.setText("");
        mNextButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                loadPage(0);
            }
        });

    }else{

        mPreviousButton.setText(mCurrentPage.getChoices().getText1());
        mNextButton.setText(mCurrentPage.getChoices().getText2());

        mPreviousButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int previousPage = mCurrentPage.getChoices().getPreviousPage();
                loadPage(previousPage);
            }
        });

        mNextButton.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) {
            int nextPage = mCurrentPage.getChoices().getNextPage();
            loadPage(nextPage);

        }
    });
}}
