在Listview的项目中设置RecyclerView项目的位置,可以通过以下步骤实现:
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
public class MyAdapter extends BaseAdapter {
private List<String> data;
private Context context;
public MyAdapter(List<String> data, Context context) {
this.data = data;
this.context = context;
}
@Override
public int getCount() {
return data.size();
}
@Override
public Object getItem(int position) {
return data.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
convertView = LayoutInflater.from(context).inflate(R.layout.item_layout, parent, false);
viewHolder = new ViewHolder();
viewHolder.recyclerView = convertView.findViewById(R.id.recyclerView);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
// 设置RecyclerView的位置
LinearLayoutManager layoutManager = new LinearLayoutManager(context);
layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
viewHolder.recyclerView.setLayoutManager(layoutManager);
// 设置RecyclerView的适配器
List<String> recyclerViewData = new ArrayList<>();
// 添加RecyclerView的数据
// ...
RecyclerViewAdapter recyclerViewAdapter = new RecyclerViewAdapter(recyclerViewData);
viewHolder.recyclerView.setAdapter(recyclerViewAdapter);
return convertView;
}
private static class ViewHolder {
RecyclerView recyclerView;
}
}
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
private List<String> data;
public RecyclerViewAdapter(List<String> data) {
this.data = data;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_item_layout, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
String item = data.get(position);
holder.textView.setText(item);
}
@Override
public int getItemCount() {
return data.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
TextView textView;
public ViewHolder(@NonNull View itemView) {
super(itemView);
textView = itemView.findViewById(R.id.textView);
}
}
}
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
ListView listView = findViewById(R.id.listView);
List<String> listData = new ArrayList<>();
// 添加Listview的数据
// ...
MyAdapter myAdapter = new MyAdapter(listData, this);
listView.setAdapter(myAdapter);
通过以上步骤,你可以在Listview的项目中设置RecyclerView项目的位置。这样,每个Listview的item中都会包含一个独立的RecyclerView,并且可以根据需要设置RecyclerView的布局方式和数据。
