Question

经过多次努力，我在这里发布我的问题并希望我能得到解决方案。我正在尝试在recyclerview中填充一个gridView但是在每个位置我在网格视图中都有不同的项目，我面临的问题假设我有2个位置0处的项目和位置1处的6项目我的回收站视图每次占用六个项目的空间，它不会通过在0位置仅显示两个项目来填充，我如何实现这一目标：

我的RecyclerView适配器代码是： -

public class RecyclerViewDashItemAdapter extends RecyclerView.Adapter<RecyclerViewDashItemAdapter.ViewHolder> {
    Context mContext;
    WacsDashboardItemResponse wacsDashboardItemResponse;
    GridViewItemBaseAdapter gridViewItemBaseAdapter;

    public RecyclerViewDashItemAdapter(Context mContext, WacsDashboardItemResponse wacsDashboardItemResponse) {
        this.mContext = mContext;
        this.wacsDashboardItemResponse = wacsDashboardItemResponse;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_view_dash_item_adapter, parent, false);
        ViewHolder viewHolder = new ViewHolder(v);
        return viewHolder;
    }

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

        gridViewItemBaseAdapter = new GridViewItemBaseAdapter(mContext,
                wacsDashboardItemResponse.subGroup.get(position).itemArray);

        holder.gridViewDashItem.setAdapter(gridViewItemBaseAdapter);

    }

    @Override
    public int getItemCount() {
        return wacsDashboardItemResponse.subGroup.size();
    }

    class ViewHolder extends RecyclerView.ViewHolder {

        GridView gridViewDashItem;

        public ViewHolder(View itemView) {

            super(itemView);

            gridViewDashItem = (GridView) itemView.findViewById(R.id.gridViewDashItem);
        }
    }
}

我的RecyclerView适配器的xml是： -

<?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:background="@android:drawable/edit_text"
    android:orientation="vertical">

    <GridView
        android:id="@+id/gridViewDashItem"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center_horizontal"
        android:columnWidth="300dp"
        android:horizontalSpacing="2dp"
        android:numColumns="2"
        android:padding="2dp"
        android:stretchMode="columnWidth"
        android:verticalSpacing="8dp" />

</LinearLayout>

我的GridView代码是： -

public class GridViewItemBaseAdapter extends BaseAdapter {
    Context mContext;
    List<WacsDashboardItemResponse.SubGroup.ItemArray> itemArray;

    public GridViewItemBaseAdapter(Context mContext, List<WacsDashboardItemResponse.SubGroup.ItemArray> itemArray) {
        this.mContext = mContext;
        this.itemArray = itemArray;
    }

    @Override
    public int getCount() {

        return itemArray.size();
    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup viewGroup) {
        LayoutInflater inflater = (LayoutInflater) mContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View gridView = null;

        if (convertView == null) {

            gridView = new View(mContext);
            gridView = inflater.inflate(R.layout.grid_view_dash_item, null);
            TextView itemName = (TextView) gridView.findViewById(R.id.itemName);
            itemName.setText(itemArray.get(position).itmeDesc);


        }
        return gridView;
    }
}

网格视图的我的Xml是： -

<?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:gravity="center_vertical"
    android:orientation="horizontal">

    <com.orbitsysindia.repairordermanagement.servicereception.util.custom.TextViewMedium
        android:id="@+id/itemName"
        style="@style/textColorBlack_14sp"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:text="Check Engine" />

    <ImageView
        android:layout_width="45dp"
        android:layout_height="45dp"
        android:layout_marginEnd="10dp"
        android:src="@drawable/wiperblade" />

    <Switch
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:theme="@style/SwitchTheme" />

</LinearLayout>

我在每个位置都有不同的项目，如何解决每个部分的高度问题，先谢谢。

你必须修复gridview项目的高度，因为它目前是matchparent，所以它采取最大高度

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="320dp"
android:gravity="center_vertical"
android:orientation="horizontal">

<com.orbitsysindia.repairordermanagement.servicereception.util.custom.TextViewMedium
    android:id="@+id/itemName"
    style="@style/textColorBlack_14sp"
    android:layout_width="100dp"
    android:layout_height="wrap_content"
    android:text="Check Engine" />

<ImageView
    android:layout_width="45dp"
    android:layout_height="45dp"
    android:layout_marginEnd="10dp"
    android:src="@drawable/wiperblade" />

<Switch
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/SwitchTheme" />

无法在回收站视图中维护网格视图的大小？
