如何使用daimajia/AndroidImageSlider库在图像的滑动上更改TextView的文本？

dependencies {
    implementation 'com.daimajia.slider:library:1.1.5@aar'
}

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.daimajia.slider.library.SliderLayout
        android:id="@+id/slider"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:text="默认文本"
        android:textSize="18sp" />
</RelativeLayout>

        sliderLayout.addSlider(sliderView1);
        sliderLayout.addSlider(sliderView2);

        sliderLayout.addOnPageChangeListener(new ViewPagerEx.OnPageChangeListener() {
            @Override

                String description = sliderLayout.getCurrentSlider().getDescription();
                textView.setText(description);
            }

            @Override
            public void onPageScrollStateChanged(int state) {
                // 页面滚动状态改变时的回调
            }
        });
    }

    @Override
    protected void onStop() {
        sliderLayout.stopAutoCycle();
        super.onStop();
