在RecyclerView中使用LinearLayoutManager時,可以通過設置一個空的Adapter來處理空數據情況。以下是一種可能的方法:
public class EmptyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
return null;
}
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
}
@Override
public int getItemCount() {
return 0;
}
}
RecyclerView recyclerView = findViewById(R.id.recyclerView);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
if (dataList.isEmpty()) {
recyclerView.setAdapter(new EmptyAdapter());
} else {
recyclerView.setAdapter(new YourAdapter(dataList));
}
通過以上方法,可以在LinearLayoutManager中處理空數據情況,顯示一個空的列表視圖。
