Question

我有一个带有2个布局的Recyclerview，
一个是我的谷歌地图，
两个是关于我必须在地图中指出的额外细节。

我的适配器中的代码是这样的。

public class AdapterTrending extends RecyclerView.Adapter<AdapterTrending.MyTrendingHolder> {
private int viewType = 0;
private Context mContext;
private ArrayList<String> reviewTrending = new ArrayList<>();

public AdapterTrending(Context context, ArrayList<String> reviewTrending) {
    this.mContext = context;
    this.reviewTrending = reviewTrending;
}

@Override
public MyTrendingHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    int listViewItemType = getItemViewType(viewType);
        if (listViewItemType == 0) {
            return new MyGoogleMap(LayoutInflater.from(mContext).inflate(R.layout.custom_googlemap_layout, parent, false));
        } else {
            return new MyTrendings(LayoutInflater.from(mContext).inflate(R.layout.custom_trending_layout, parent, false));
        }
}

@Override
public void onBindViewHolder(MyTrendingHolder holder, int position) {

}

@Override
public int getItemCount() {
    return 10;
}

@Override
public int getItemViewType(int position) {
    if (position == 0) {
        viewType = 0;
    }
    if (position >= 1) {
        viewType = position;
    }
    return viewType;
}


class MyTrendings extends MyTrendingHolder {
    public MyTrendings(View itemView) {
        super(itemView);
    }
}

class MyGoogleMap extends MyTrendingHolder {
    public MyGoogleMap(View itemView) {
        super(itemView);
    }
}

class MyTrendingHolder extends RecyclerView.ViewHolder {
    public MyTrendingHolder(View itemView) {
        super(itemView);
    }
}
}

我有三个标签的tabpager 第一个标签是这个。
第二页和第三页什么都没有当我滑到第三页并返回第二页时，
发生此错误。

对于我的XML，这是指导我的错误。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="match_parent"
          android:layout_height="match_parent"

    <LinearLayout

    android:layout_height="match_parent"
    android:orientation="vertical">


    <LinearLayout

        android:layout_height="160dp">

        <fragment

            class="com.google.android.gms.maps.SupportMapFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    </LinearLayout>
</LinearLayout>

Answer 1

我建议，以编程方式膨胀SupportMapFragment 而不是以XML格式添加片段。

public class AdapterTrending extends RecyclerView.Adapter<AdapterTrending.MyTrendingHolder> { private FragmentManager mFragmentManager; private int viewType = 0; private Context mContext; private ArrayList<String> reviewTrending = new ArrayList<>(); public AdapterTrending(Context context, FragmentManager fragmentManager, ArrayList<String> reviewTrending) { this.mContext = context; this.mFragmentManager = fragmentManager; this.reviewTrending = reviewTrending; } @Override public MyTrendingHolder onCreateViewHolder(ViewGroup parent, int viewType) { int listViewItemType = getItemViewType(viewType); if (listViewItemType == 0) { return new MyGoogleMap(LayoutInflater.from(mContext).inflate(R.layout.custom_googlemap_layout, parent, false)); } else { return new MyTrendings(LayoutInflater.from(mContext).inflate(R.layout.custom_trending_layout, parent, false)); } } @Override public void onBindViewHolder(ExperienceListHolder holder, int position) { // Setup other views here SupportMapFragment fragment = SupportMapFragment.newInstance(options); FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction(); fragmentTransaction .replace(R.id.map_container, fragment) .addToBackStack(null) .commit(); fragment.getMapAsync(this); } @Override public int getItemCount() { return 10; } @Override public int getItemViewType(int position) { if (position == 0) { viewType = 0; } if (position >= 1) { viewType = position; } return viewType; } class MyTrendings extends MyTrendingHolder { public MyTrendings(View itemView) { super(itemView); } } class MyGoogleMap extends MyTrendingHolder { public MyGoogleMap(View itemView) { super(itemView); } } class MyTrendingHolder extends RecyclerView.ViewHolder { public MyTrendingHolder(View itemView) { super(itemView); } } }

XML现在看起来像

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <LinearLayout android:id="@+id/map_container" android:layout_width="match_parent" android:layout_height="160dp"> </LinearLayout> </LinearLayout>

使用多个视图在Recyclerview中扩充类碎片时出错
