我有一个Fragment，它有一个TextView，点击时应该重定向到另一个Activity。我为TextView实现了OnClickListener＆＃34;空＆＃34;但它不起作用。我点了一个System.out来打印一些东西，甚至不打印它。
这是我的片段：
public class OrderFragment extends Fragment implements AdapterView.OnItemClickListener {
private BeeGif viewGif;
private ListView lstChefOrders;
private ArrayList<OrderList> orderLists, listOrders;
private TextView empty;
private SwipeRefreshLayout mSwipeRefreshLayout;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_order, null, false);
}
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
empty = (TextView) view.findViewById(R.id.empty);
lstChefOrders = (ListView) view.findViewById(R.id.lstChefOrders);
lstChefOrders.setOnItemClickListener(this);
RelativeLayout viewLayout = (RelativeLayout) view.findViewById(R.id.beeGifOrder);
viewGif = (BeeGif) viewLayout.findViewById(R.id.view);
mSwipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_refresh);
mSwipeRefreshLayout.setColorSchemeResources(R.color.colorPrimary);
mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
if (NetworkHelper.isOnline(getActivity())) {
callOrderService();
} else {
NetworkHelper.noNetworkToast(getActivity());
}
}
});
if (NetworkHelper.isOnline(getActivity())) {
if (!PrefernceHelper.getBoolean(getActivity(), Commons.Constants.USERLOGGEDIN)) {
lstChefOrders.setVisibility(View.GONE);
empty.setText(R.string.order_history);
empty.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
System.out.println("Teste");
Intent intent = new Intent();
intent.setClass(getActivity(), SignInActivity.class);
startActivity(intent);
}
});
} else {
lstChefOrders.setVisibility(View.VISIBLE);
empty.setVisibility(View.GONE);
viewGif.setVisibility(View.VISIBLE);
callOrderService();
}
} else
NetworkHelper.noNetworkToast(getActivity());
}
private void callOrderService() {
// Log.e("TAG", "Kuch toh patta chala : " + PrefernceHelper.getString(getActivity(), Commons.Constants.USER_ID));
new VolleyHelper(getActivity()).get("foodiesOrderListing/" + PrefernceHelper.getString(getActivity(), Commons.Constants.USER_ID), null, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
viewGif.setVisibility(View.GONE);
mSwipeRefreshLayout.setRefreshing(false);
// Log.e("TAG", "Thanks for the return GIFT : " + response.toString());
try {
// HashMap<String, List<OrderList>> listDataChild = new HashMap<String, List<OrderList>>();
ArrayList<OrderId> orderIdList = new ArrayList<>();
orderLists = new ArrayList<>();
listOrders = new ArrayList<>();
JSONArray array = response.getJSONArray("order_ids");
for (int i = 0; i < array.length(); i++) {
String status = "";
OrderList orderList1 = new OrderList();
OrderId orderId = new OrderId();
JSONObject object = array.getJSONObject(i);
String date = object.getString("order_date");
orderId.setOrder_date(date);
orderId.setOrderid(object.getString("orderid"));
orderIdList.add(orderId);
//orderList1.setOrder_status("Pending");
orderList1.setOrderid(object.getString("orderid"));
orderList1.setChef_id("");
orderList1.setUser_id("");
orderList1.setItem_id("");
orderList1.setItem_qty("");
orderList1.setItem_price("");
orderList1.setItem_name(object.getString("orderid"));
orderList1.setOrderDate(object.getString("order_date"));
if (i % 2 == 0) {
orderList1.setBackGroundColor(Commons.Constants.TYPE_WHITE);
} else {
orderList1.setBackGroundColor(Commons.Constants.TYPE_GREY);
}
//listOrders.add(orderList1);
JSONArray orderListArray = response.getJSONArray("orderList");
for (int j = 0; j < orderListArray.length(); j++) {
OrderList orderList = new OrderList();
JSONObject orderListObject = orderListArray.getJSONObject(j);
if (orderIdList.get(i).getOrderid().equals(orderListObject.getString("orderid"))) {
status = orderListObject.getString("order_status");
//orderList.setOrder_status(orderListObject.getString("order_status"));
//orderList.setOrderid(orderListObject.getString("orderid"));
//orderList.setChef_id(orderListObject.getString("chef_id"));
//orderList.setUser_id(orderListObject.getString("user_id"));
//orderList.setItem_id(orderListObject.getString("item_id"));
//orderList.setItem_qty(orderListObject.getString("item_qty"));
//orderList.setItem_price(orderListObject.getString("item_price"));
//orderList.setItem_name(orderListObject.getString("orderid"));
//orderList.setOrderDate(date);
/*if (j % 2 == 0) {
orderList.setBackGroundColor(Commons.Constants.TYPE_WHITE);
} else {
orderList.setBackGroundColor(Commons.Constants.TYPE_GREY);
}
orderLists.add(orderList);*/
}
}
orderList1.setOrder_status(status);
listOrders.add(orderList1);
// listDataChild.put(orderId.getOrder_date(), orderLists);
}
if (listOrders.size() > 0) {
OrderListAdapter adapter = new OrderListAdapter(getActivity(), listOrders); //listDataChild (was the 3rd paramter for the Constructor earlier)
lstChefOrders.setAdapter(adapter);
empty.setVisibility(View.GONE);
} else {
if (getView().findViewById(R.id.empty) != null)
lstChefOrders.setEmptyView(getView().findViewById(R.id.empty));
// for (int i = 0; i < adapter.getGroupCount(); i++)
// lstChefOrders.expandGroup(i);
}
} catch (JSONException je) {
}catch (NullPointerException npe){
npe.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent();
intent.setClass(getActivity(), OrderDetailsActivity.class);
//intent.putExtra("orderID", orderLists.get(position).getOrderid());
intent.putExtra("orderID", listOrders.get(position).getOrderid());
startActivity(intent);
}
}
这是带有textView的片段的XML：

如果这些条件为false，则不会将单击侦听器绑定到文本视图：

这样做：
empty.setText(getResources().getString(R.string.order_history));
empty.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getBaseContext(), "Teste", Toast.LENGTH_LONG).show();
Intent intent = new Intent(this, SignInActivity.class);
startActivity(intent);
}
});
