Java 回收视图项目中的Android回收视图,java,android,android-recyclerview,Java,Android,Android Recyclerview,我正在为一个学校项目构建一个应用程序，我想要的是在我的应用程序中为学生制作一个周计划。为此，我需要在recyclerview项目中添加一个recyclerview，但当我运行我的应用程序时，它不会显示任何内容。我认为这是我的错误 logcat:06-19 15:43:36.926 2980-2980/com.sapps.tools.dedykapp E/RecyclerView﹕ 无适配器连接；跳过布局。这是我的代码： PlannerActivity.java //day planner mon

我正在为一个学校项目构建一个应用程序，我想要的是在我的应用程序中为学生制作一个周计划。为此，我需要在recyclerview项目中添加一个recyclerview，但当我运行我的应用程序时，它不会显示任何内容。我认为这是我的错误

logcat:

06-19 15:43:36.926 2980-2980/com.sapps.tools.dedykapp E/RecyclerView﹕ 无适配器连接；跳过布局。

这是我的代码：

PlannerActivity.java

//day planner monday
    ArrayList<DayItems> mon = new ArrayList<>();
    mon.add(new DayItems("huiswerk maken"));

    LinearLayout v = (LinearLayout)getLayoutInflater().inflate(R.layout.dayitems, viewGroup);

    RecyclerView dayPlan = (RecyclerView)v.findViewById(R.id.mon);
    dayPlan.setHasFixedSize(true);
    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
    linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    dayPlan.setLayoutManager(linearLayoutManager);

    DayRecAdapter dayAdapter = new DayRecAdapter(mon);
    dayPlan.setAdapter(dayAdapter);

    //planner
    RecyclerView plan = (RecyclerView)findViewById(R.id.planner);
    plan.setHasFixedSize(true);
    LinearLayoutManager linManager = new LinearLayoutManager(this);
    linManager.setOrientation(LinearLayoutManager.VERTICAL);
    plan.setLayoutManager(linManager);

    PlannerRecAdapter recAdapter = new PlannerRecAdapter(R.layout.dayitems);
    plan.setAdapter(recAdapter);

//日程安排周一
ArrayList mon=新的ArrayList（）；
周一添加（新的日项目（“huiswerk maken”）；
LinearLayout v=（LinearLayout）GetLayoutFlater（）.充气（R.layout.dayitems，视图组）；
RecyclerView日计划=（RecyclerView）v.findViewById（R.id.mon）；
dayPlan.setHasFixedSize（true）；
LinearLayoutManager LinearLayoutManager=新的LinearLayoutManager（此）；
linearLayoutManager.setOrientation（linearLayoutManager.VERTICAL）；
dayPlan.setLayoutManager（linearLayoutManager）；
DayRecAdapter dayAdapter=新的DayRecAdapter（周一）；
dayPlan.setAdapter（dayadadapter）；
//计划者
RecyclerView计划=（RecyclerView）findViewById（R.id.planner）；
plan.setHasFixedSize（真）；
LinearLayoutManager linManager=新的LinearLayoutManager（此）；
linManager.setOrientation（LinearLayoutManager.VERTICAL）；
plan.setLayoutManager（linManager）；
PlannerAdapter-recAdapter=新的PlannerAdapter（R.layout.dayitems）；
计划。设置适配器（重新适配器）；

我的议程的两个适配器：

todo列表的适配器，位于recyclerview项中：

public class DayRecAdapter extends RecyclerView.Adapter<DayViewHolder> {

ArrayList<DayItems> mList;

public DayRecAdapter(ArrayList<DayItems> mList){
    this.mList = mList;
}

public int getItemCount(){
    return mList.size();
}

public DayViewHolder onCreateViewHolder(ViewGroup viewGroup, int position){
    View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.planitem, viewGroup, false);
    DayViewHolder DVH = new DayViewHolder(v);
    return DVH;
}

public void onBindViewHolder(DayViewHolder vHolder, int i){
    vHolder.dayText.setText(mList.get(i).todo);
}

}

公共类DayRecAdapter扩展了RecyclerView.Adapter{ 阵列列表；公共DayRecAdapter（ArrayList mList）{ this.mList=mList； } public int getItemCount（）{ 返回mList.size（）； } public DayViewHolder onCreateViewHolder（视图组视图组，内部位置）{ 视图v=LayoutInflater.from（viewGroup.getContext（））.flate（R.layout.planitem，viewGroup，false）； DayViewHolder DVH=新的DayViewHolder（v）；返回DVH； } BindViewHolder上的公共无效（DayViewHolder vHolder，int i）{ vHolder.dayText.setText（mList.get（i.todo））； } } 主回收器视图的适配器：

public class PlannerRecAdapter extends RecyclerView.Adapter<PlannerViewHolder> {

int layoutResource;

public PlannerRecAdapter(int layoutResource){
    this.layoutResource = layoutResource;
}

public int getItemCount(){
    return 1;
}

public PlannerViewHolder onCreateViewHolder(ViewGroup viewGroup, int position){
    View v = LayoutInflater.from(viewGroup.getContext()).inflate(layoutResource, viewGroup, false);
    PlannerViewHolder PVH = new PlannerViewHolder(v);
    return PVH;
}

public void onBindViewHolder(PlannerViewHolder holder, int i){

}
}

公共类PlannerAdapter扩展了RecyclerView.Adapter{
国际布局资源；
公共规划师再适应（内部布局资源）{
this.layoutResource=layoutResource；
}
public int getItemCount（）{
返回1；
}
public Planner ViewHolder onCreateViewHolder（视图组视图组，内部位置）{
视图v=LayoutInflater.from（viewGroup.getContext（））.flate（layoutResource，viewGroup，false）；
PlannerViewHolder PVH=新的PlannerViewHolder（v）；
返回PVH；
}
BindViewHolder上的公共无效（PlannerViewHolder，int i）{
}
}

以下是PlannerAdapter的布局资源：

    <LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

        android:layout_height="wrap_content"
        card_view:cardCornerRadius="4dp"
        card_view:cardBackgroundColor="#9CCC65"
        android:layout_margin="13dp">

            android:textSize="15dp"
            android:textStyle="bold"
            android:padding="14dp"
            android:text="Maandag"/>

        <android.support.v7.widget.RecyclerView
            android:id="@+id/mon"
            android:layout_height="wrap_content"
            android:layout_width="fill_parent"
            android:padding="14dp"
            android:scrollbars="vertical" />

    </android.support.v7.widget.CardView>
