我想要创建的是一个水平滚动图库.我有一个RecyclerView(支持22.0.0).我遇到的问题是,当我滚动到最后然后向后滚动时,通常会丢失一个图像,有时会丢失两个图像.奇怪的是,当我不停地来回扫动时,可能会丢失不同的图像.这是项目的布局:

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="160dp">

<ImageView
    android:id="@+id/product_variation_image"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scaleType="centerCrop"
    android:layout_gravity="center"/>

public class TestAdapter extends RecyclerView.Adapter<TestAdapter.ViewHolder> {
private String[] mDataset;

public static class ViewHolder extends RecyclerView.ViewHolder {

    public ImageView mImageView;
    public ViewHolder(View v) {
        super(v);
        mImageView = (ImageView) v.findViewById(R.id.product_variation_image);
    }
}

public TestAdapter(String[] myDataset) {
    mDataset = myDataset;
}

@Override
public TestAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                               int viewType) {
    // create a new view
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.variaton_list_item, parent, false);
    ViewHolder vh = new ViewHolder(v);
    return vh;
}

@Override
public …
