Java 在RecyclerView AndroidX中的项目之间添加不同的布局

我想在我的recyclerview中的项目之间添加不同的布局，我在第一个布局中有3个项目，然后我在项目编号2中添加第二个布局，所以现在应该有4个项目，（1-FirstLayout）-（2-SecondLayout）-（3FirstLayout）-（4FirstLayout），但我意识到我选择的位置从第二个布局替换为第一个布局，它变成这样（1-FirstLayout）-（2-SecondLayout）-（3FirstLayout） 我不知道如何修理它

这是我的适配器

    this.mContext = mContext;
    this.modelGameReviews = modelGameReviews;
    this.mListener = mListener;
}

//Container
@Override

    View v = null;

    if (viewType == TYPE_TOPREVIEWER) {
        v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_gamereviewtopreviewer, null);
        return new GameReviewTopReviewerViewHolder(v);
    } else if (viewType == TYPE_ADSBANNER) {
        v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_adsbannerdummy, null);

    }

}

您错误地实现了此方法

@Override
public int getItemCount() {
    int itemCount = 0;
    if(mWithTopReviewer == true){
        itemCount++;
    }
        itemCount = modelGameReviews.size();

    return itemCount;
}

应该是类似的

@Override
public int getItemCount() {
    int itemCount = modelGameReviews.size();
    if(mWithTopReviewer == true){
        itemCount++;
    }

    return itemCount;
}

使用recycler视图的getItemViewType（）方法使用多个视图types@Sandeepdhiman请阅读我的适配器代码，我已经实现了getItemViewType（），我尝试了它，它变成了崩溃java.lang.IndexOutOfBoundsException:Index:3，Size:3位于java.util.ArrayList.get（ArrayList.java:437）在com.indofun.android.indojoy.Adapters.Adapter\u GameReview.AdapterGameReview.onBindViewHolder（AdapterGameReview.java:103）@SunggakiChannel返回值

getItemCount（）

表示列表中有多少项。你的数组大小是3。但是，如果要显示四个项目，数组还应该有4个项目。因此，如果（mWithTopReviewer==true）{itemCount++；}应该使大小变为4，但它仍然崩溃

@Override
public int getItemCount() {
    int itemCount = modelGameReviews.size();
    if(mWithTopReviewer == true){
        itemCount++;
    }

    return itemCount;
}
