Help。 RecyclerViewに何も表示されない理由はわかりません。アダプターの私の実装は正しいです。どこが間違っているのか分かりません。RecyclerViewに何も表示されません
ここで断片クラスです：
public class RemittanceFragment extends Fragment implements View.OnClickListener {
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";
private String mParam1;
private String mParam2;
@BindView(R.id.remit_cancel_view)
View remitCancelView;
@BindView(R.id.remit_checkpaid_view)
View remitCheckPaidView;
@BindView(R.id.remit_create_view)
View remitCreateView;
@BindView(R.id.remit_main_menu)
View remitMainMenuView;
@BindView(R.id.btn_cancel)
Button btnCancel;
@BindView(R.id.btn_checkpaid)
Button btnCheckPaid;
@BindView(R.id.btn_create)
Button btnCreate;
@BindView(R.id.btn_back)
TextView btnGoBack;
@BindView(R.id.btn_back2)
TextView btnGoBack2;
@BindView(R.id.remit_header_title)
TextView tvRemitHeaderTitle;
@BindView(R.id.remit_cancel_list)
RecyclerView cancelRecyclerView;
public RemittanceFragment() {
// Required empty public constructor
}
public static RemittanceFragment newInstance() {
RemittanceFragment fragment = new RemittanceFragment();
Bundle args = new Bundle();
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_remit_menu, container, false);
ButterKnife.bind(this, view);
remitCancelView.setVisibility(View.GONE);
remitCheckPaidView.setVisibility(View.GONE);

populateData();
break;

}
}
public void populateData() {
List<RemitTransaction> transactions = new ArrayList<>();

}
return transactions;
}
}
public class RemitTransactionListAdapter

@Override

}
}
}
}
そしてここでは、レイアウトファイルです：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/utility_white"
android:paddingTop="@dimen/dimen_margin_vertical_extra_large">
<android.support.v7.widget.RecyclerView
android:id="@+id/remit_cancel_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
そしてここlist_itemレイアウトです：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/remit_item_refno"
style="@style/RemitListItem"
android:text="VW832191"
android:textStyle="bold"
android:layout_alignParentStart="true"/>
<TextView
android:id="@+id/remit_item_amount"
style="@style/RemitListItem"
android:text="100.00"
android:textStyle="bold"
android:layout_alignParentEnd="true"/>
<TextView
android:id="@+id/remit_item_date"
style="@style/RemitListItem"
android:text="2016-07-20"
android:layout_alignParentStart="true"
android:layout_below="@+id/remit_item_refno"/>
<TextView
android:id="@+id/remit_item_msisdn"
style="@style/RemitListItem"
android:text="09273450686"
android:layout_alignParentEnd="true"
android:layout_below="@+id/remit_item_amount"/>
</RelativeLayout>
は、あなたがすべて私を助けることができる願っています。ありがとうございました！
これはすべてあなたのXMLですか？ 'remit_cancel_view'、' remit_checkpaid_view'などはどこに定義されていますか？あなたのフラグメントで定義されているビューの束にバインドされているように見えますが、XMLではありません。 – Neil
こんにちは@Neil私は 'remit_cancel_view'を使っています。他のビューは' 'タグの中に入っています –

@ imaN.NeoFighTの答えを見てください。それはあなたの問題を解決するかもしれません。 – Neil
