怎么往回滑动到初始位置，不能再滑动了，能否无限回滑呢？无限下滑可以 #1

里面的原理是利用整形最大值作为适配器的数量大小,你是怎么滑到头的

第一次进去默认就是第一张图片往左滑动就到头了

xuezj commented 6 years ago

只有一张图吗?

itzhaokun commented 6 years ago

4张图，现在可以往左滑动了，有时候在运行中和第一次加载会报错 java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.support.v7.widget.RecyclerView$LayoutManager.canScrollVertically()' on a null object reference at com.xuezj.cardbanner.view.CardView.findViewAtCenter(CardView.java:163) at com.xuezj.cardbanner.view.CardView.onLayout(CardView.java:67) 你能看下这个错误吗

@GlideModule public class MyAppGlideModule extends AppGlideModule {

@Override
public boolean isManifestParsingEnabled() {
    return false;
}

} 创建这个类。重写这个方法就好了，改一下吧

xuezj commented 6 years ago

你是不是自己也引用Glide了

itzhaokun commented 6 years ago

是的，有什么冲突吗？

itzhaokun commented 6 years ago

嗯，这个问题我在项目中解决了
