我尝试在loadOrdersData()中的setAdapter()之前添加:adapter.notifyDataSetChanged();，但这没有任何意义.有人看到它是由什么引起的吗?

I tried adding: adapter.notifyDataSetChanged(); before setAdapter() in loadOrdersData() but it makes no sense. Does anyone see what it is caused by?

代码如下:

MainActivity:

MainActivity:

public class CourierActivity extends AppCompatActivity { private TableLayout orderTable; private RecyclerView recyclerView; private RecycleAdapter adapter; private List<OrderListItem> listItems; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.courier_main); recyclerView = (RecyclerView) findViewById(R.id.rv); recyclerView.setHasFixedSize(true); recyclerView.setLayoutManager(new LinearLayoutManager(CourierActivity.this)); adapter = new RecycleAdapter(listItems, getApplicationContext()); recyclerView.setAdapter(adapter); loadOrdersData(); } private void loadOrdersData() { RequestQueue queue = Volley.newRequestQueue(this); StringRequest sr = new StringRequest(Request.Method.GET, URL, new Response.Listener<String>() { @Override public void onResponse(String response) { listItems = new ArrayList<>(); try { String rsp = new String(response.getBytes("ISO-8859-1"), "UTF-8"); JSONArray orders = new JSONArray(rsp); for (int i = 0; i < orders.length(); i++) { OrderListItem listItem = new OrderListItem( // .. ); listItems.add(listItem); } adapter = new RecycleAdapter(listItems, getApplicationContext()); recyclerView.setAdapter(adapter); } catch (JSONException | UnsupportedEncodingException e) { e.printStackTrace(); } } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_SHORT); } }) { @Override public Map<String, String> getHeaders() throws AuthFailureError { Map<String, String> params = new HashMap<String, String>(); return params; } }; queue.add(sr); } }

OrderListItem:

OrderListItem:

public class OrderListItem { private String name; private String status; private String price; private String courier; public OrderListItem(String name, String status, String price, String courier) { this.name = name; this.status = status; this.price = price; this.courier = courier; } public String getName() { return name; } public String getStatus() { return status;} public String getPrice() { return price; } public String getCourier() { return courier; } }

RecycleAdapter:

RecycleAdapter:

public class RecycleAdapter extends RecyclerView.Adapter<RecycleAdapter.ViewHolder> { private List<OrderListItem> listItems; private Context context; public RecycleAdapter(List<OrderListItem> listItems, Context context) { this.listItems = listItems; this.context = context; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View v = LayoutInflater.from(parent.getContext()) .inflate(R.layout.rv_item, parent, false); return new ViewHolder(v); } @Override public void onBindViewHolder(ViewHolder holder, int position) { OrderListItem listItem = listItems.get(position); holder.TextViewName.setText(listItem.getName()); holder.TextViewStatus.setText(listItem.getStatus()); holder.TextViewPrice.setText(listItem.getPrice()); holder.TextViewCourier.setText(listItem.getCourier()); } @Override public int getItemCount() { int count = 0; if (listItems != null && !listItems.isEmpty()) { count = listItems.size(); } return count; } public class ViewHolder extends RecyclerView.ViewHolder { public TextView TextViewName; public TextView TextViewStatus; public TextView TextViewPrice; public TextView TextViewCourier; public ViewHolder(View itemView) { super(itemView); TextViewName = (TextView) itemView.findViewById(R.id.orderListName); TextViewStatus = (TextView) itemView.findViewById(R.id.orderListStatus); TextViewPrice = (TextView) itemView.findViewById(R.id.orderListPrice); TextViewCourier = (TextView) itemView.findViewById(R.id.orderListCourier); } } }

@ layout/rv_item.xml:

@layout/rv_item.xml:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="schemas.android/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content"> <android.support.v7.widget.CardView xmlns:card_view="schemas.android/apk/res-auto" android:layout_margin="@dimen/activity_horizontal_margin" android:layout_height="wrap_content" android:layout_width="match_parent"> <LinearLayout android:padding="@dimen/activity_horizontal_margin" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/orderListName" android:text="Order name" android:textAppearance="@style/Base.TextAppearance.AppCompat.Large" android:layout_width="match_parent" android:layout_height="wrap_content" /> <TextView android:id="@+id/orderListStatus" android:text="Status" android:layout_width="match_parent" android:layout_height="wrap_content" /> <TextView android:id="@+id/orderListPrice" android:text="Price" android:layout_width="match_parent" android:layout_height="wrap_content" /> <TextView android:id="@+id/orderListCourier" android:text="Courier" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout> </android.support.v7.widget.CardView> </LinearLayout>

@ layout/main.xml:

@layout/main.xml:

<?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout xmlns:android="schemas.android/apk/res/android" xmlns:tools="schemas.android/tools" xmlns:app="schemas.android/apk/res-auto" tools:context="com.example.seether.myapplication.CourierActivity" android:background="#fff" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/drawerLayout"> <android.support.v7.widget.RecyclerView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/rv"/> </android.support.v4.widget.DrawerLayout>

编辑.如果我在listItems中输入自定义数据，则可以完美运行而无需日志警告.

EDIT. Works perfect without log's warnings if I enter custom data into listItems.

推荐答案

不要将 list 对象从活动传递到适配器.而是在适配器中有一个单独的阵列列表. 将您的适配器构造函数更改为此:

Don't pass the list object from activity to adapter. Instead have a separate array list in adapter. Change your adapter constructor to this:

public RecycleAdapter(List<OrderListItem> listItems, Context context) { this.listItems = new ArrayList<>(listItems); this.context = context; }

并且正如Maddy建议的那样，在适配器中使用setMethod传递listitem数组，并将所有项目添加到其中，然后调用notifyDataSetChanged.

And as Maddy suggested use a setMethod in adapter passing the listitem array and adding all items to it and calling notifyDataSetChanged.

我想当您在活动和适配器中不使用相同的listitems对象时，这应该可以解决您的问题.

I guess this should solve your problem when you don't use the same listitems object in activity and adapter.
