我有以下问题，我有3种不同对象的json响应。我需要在一个列表视图中显示此数据。我正在使用GSON库反序列化JSON。
Json文件

}

}
]
}
}
这是我的适配器
public class RequestInListAdapter extends ArrayAdapter<Data> {
private Context context;
private ArrayList<Data> RequestInListItem;
public RequestInListAdapter(Context context, ArrayList<Data> arrayList) {
super(context, 0, arrayList);
this.context = context;
this.RequestInListItem = arrayList;
}
@SuppressLint("ResourceAsColor")
@NonNull
@Override
public View getView(final int position, @Nullable View convertView, @NonNull ViewGroup parent) {
final Data card_item = RequestInListItem.get(position);
for (Response order : responses) {
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.order_item, parent, false);
}
TextView desc = convertView.findViewById(R.id.description);
TextView address = convertView.findViewById(R.id.address);
TextView dnt = convertView.findViewById(R.id.dnt);
TextView category = convertView.findViewById(R.id.category);
TextView status = convertView.findViewById(R.id.status);
RelativeLayout card_layout = convertView.findViewById(R.id.card_layout);
de.hdodenhof.circleimageview.CircleImageView photo_template = convertView.findViewById(R.id.photo_template);
desc.setText(order.getOrder().getDescription());
address.setText(order.getOrder().getAddress());
Picasso.with(context).load(String.valueOf(order.getOrder().getEmployer().getPhoto())).resize(70, 70).into(photo_template);
long timestamp = order.getOrder().getCreatedAt() * 1000L;
dnt.setText(getDate(timestamp));
status.setText("Response");
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
}
});
return convertView;
}
return convertView;
}
}
这段代码来自我的主班
private ArrayList<Data> arrayList = new ArrayList<>();
RequestInListAdapter adapter;
JSONReader jsonReader = new JSONReader();
BellIn bellIn = jsonReader.getBellIn(responseObj.toString());
arrayList.add(bellIn.getData());
adapter = new RequestInListAdapter(getContext(), arrayList);
listView.setAdapter(adapter);
现在Listview仅显示1个元素，但我应该得到更多。问题是因为我传递了 bellIn 对象，该对象包含3个不同的列表
public class Data {
private List<Response> responses = null;
private List<OpenOrder> open_orders = null;
private List<DirectOrder> direct_orders = null;
public List<Response> getResponses() {
return responses;
}
public void setResponses(List<Response> responses) {
this.responses = responses;
}
public List<OpenOrder> getOpenOrders() {
return open_orders;
}
public void setOpenOrders(List<OpenOrder> openOrders) {
this.open_orders = openOrders;
}
public List<DirectOrder> getDirectOrders() {
return direct_orders;
}
public void setDirectOrders(List<DirectOrder> directOrders) {
this.direct_orders = directOrders;
}
1。如何在1个Listview中显示3个不同的对象？
2。如何在ListView中显示所有项目（不仅是第一个项目）？
3。我可以为此对象使用不同的视图吗？
答案 0 :(得分：0)
进行自定义的Listview，并在元素的自定义布局中添加所有3个项目，并假设您不想在某个特定元素中显示所有项目，然后使用属性visibility使它不可见
答案 1 :(得分：0)
首先，我更改了布局。因此，最后，我在1种布局中放置了3个ListView。
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp">
<ListView
android:id="@+id/listviewResponse"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="@android:color/transparent"
android:dividerHeight="10sp"
android:paddingStart="15dp"
android:paddingEnd="15dp" />
<ListView
android:id="@+id/listviewDirect"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="@android:color/transparent"
android:dividerHeight="10sp"
android:paddingStart="15dp"
android:paddingEnd="15dp" />
<ListView
android:id="@+id/listviewOpen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="@android:color/transparent"
android:dividerHeight="10sp"
android:paddingStart="15dp"
android:paddingEnd="15dp" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.v4.widget.SwipeRefreshLayout>
我创建了3个不同的适配器并将适配器设置为Listviews
@BindView(R.id.listviewResponse)
ListView listViewResponse;
@BindView(R.id.listviewOpen)
ListView listViewOpen;
@BindView(R.id.listviewDirect)
ListView listViewDirect;
private List<Response> responses = new ArrayList<>();
private List<OpenOrder> open_orders = new ArrayList<>();
private List<DirectOrder> direct_orders = new ArrayList<>();
RequestListResponseAdapter adapterResponse;
RequestListOpenAdapter adapterOpen;
RequestListDirectAdapter adapterDirect;
adapterResponse = new RequestListResponseAdapter(getContext(), responses);
adapterOpen = new RequestListOpenAdapter(getContext(), open_orders, openType);
adapterDirect = new RequestListDirectAdapter(getContext(), direct_orders);
listViewResponse.setAdapter(adapterResponse);
listViewDirect.setAdapter(adapterDirect);
listViewOpen.setAdapter(adapterOpen);
