android - sayyam / carouselview动态更改页数

Question

我在github上使用CaruselView项目，我想动态更改PageCount，但我没有找到任何相关信息。

以下是代码示例：

public class SampleCarouselViewActivity extends AppCompatActivity {

    CarouselView carouselView;

    int[] sampleImages = {R.drawable.image_1, R.drawable.image_2, R.drawable.image_3, R.drawable.image_4, R.drawable.image_5};

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

        carouselView = (CarouselView) findViewById(R.id.carouselView);
        carouselView.setPageCount(sampleImages.length);

        carouselView.setImageListener(imageListener);
    }

    ImageListener imageListener = new ImageListener() {
        @Override
        public void setImageForPosition(int position, ImageView imageView) {
            imageView.setImageResource(sampleImages[position]);
        }
    };

}

可能会动态重置计数并设置新计数？有什么想法吗？

您必须在更改尺寸之前移除旋转木马的父级，而不必将其重新分配给旋转木马。

if (carouselView != null) {
    parentView = carouselView.getParent();
    if (parentView != null && parentView instanceof ViewGroup) {
        ViewGroup g = (ViewGroup) parentView;
        g.removeView(carouselView);
    }
}
carouselView.setPageCount(newSize);

if (parentView != null && parentView instanceof ViewGroup) {
    ViewGroup g = (ViewGroup) parentView;
    g.addView(carouselView);
}
