Ich plane, eine App zu entwickeln, die einige dynamische Daten in einem @ anzeigrecyclerCardView. Also habe ich beschlossen, ein @ hinzuzufügrecyclerView namensCheckBoxRecyclerView in meinem HauptrecyclerView. Dies ist mein Code für meine App:

Meine Hauptaktivität:

setContentView(R.layout.activity_startup);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
reminderView = (RecyclerView) findViewById(R.id.reminder_recycler_view);
RlayoutManager = new LinearLayoutManager(this);
reminderView.setLayoutManager(RlayoutManager);

setSupportActionBar(toolbar);
cardView = (CardView) findViewById(R.id.card_first);
cardView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent(getApplicationContext() , ReminderActivity.class);
        startActivity(intent);
    }
});
ReminderHelper helper = new ReminderHelper(getApplicationContext());
ReminderAdapter reminderAdapter = new ReminderAdapter(helper);
ContentValues reminderValues = new ContentValues();
ContentValues checkboxValues = new ContentValues();
// Devlopment Part ->
reminderValues.put("reminderTitle" , "A Reminder Title");
reminderValues.put("reminderLastModDate" , 0);
reminderValues.put("reminderAlarm" , 0);
reminderValues.put("reminderPicURI" , "skjshksjh");
reminderValues.put("ReminderBackground" , "#00796b");
checkboxValues.put("checkboxText" , "This is a CheckBox");
checkboxValues.put("isDone" , false);
checkboxValues.put("checkboxReminderID" , 0);
reminderAdapter.INSERT_REMINDER(reminderValues);
reminderAdapter.INSERT_CHECKBOX(checkboxValues);
File dbPath = getApplicationContext().getDatabasePath(ReminderHelper.DATABASE_NAME);
if(dbPath.exists()){
    List<Reminder> reminders = new ReminderAdapter(helper).getAllReminders();
    List<CheckBoxItem> checkBoxItems = new ReminderAdapter(helper).getAllCheckBoxes();
    RAdapter = new RAdapter(reminders , getApplicationContext() , checkBoxItems);
    reminderView.setAdapter(RAdapter);
}else{

}

Und es ist Layout-Datei:

<LinearLayout xmlns:android=",http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="8dp"
    android:paddingLeft="8dp"
    android:paddingRight="8dp"
    android:paddingTop="8dp"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.smflog.sreminder.StartupActivity"
    tools:showIn="@layout/app_bar_startup">

    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:id="@+id/reminder_recycler_view"
        android:scrollbars="vertical"
        android:layout_height="match_parent">

und in dieser recyclerView gibt es noch eine andere:

<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/reminder_card"
    card_view:cardCornerRadius="2dp"
    card_view:cardElevation="4dp"
    card_view:cardUseCompatPadding="true">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:paddingBottom="16dp"
        android:paddingLeft="8dp">

        <com.smflog.sreminder.utils.TitleView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/reminder_title"
            android:paddingTop="8dp"
            android:text="Wellcome To Google Keep !"
            android:textSize="15dp"
            android:textStyle="bold" />
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:orientation="horizontal">
<android.support.v7.widget.RecyclerView
    android:layout_width="wrap_content"
    android:id="@+id/checkbox_recycler_view"
    android:layout_height="wrap_content">

</android.support.v7.widget.RecyclerView>
        </LinearLayout>

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

Ihre Adapter, Main (RAdapter):

public class RAdapter extends RecyclerView.Adapter<RAdapter.ViewHolder> {
    List<Reminder> reminder;
    private Context context;
    private LinearLayoutManager lln;
    private CAdapter checkBoxAdapter;
    private List<CheckBoxItem> checkBoxItems;
    public static class ViewHolder extends RecyclerView.ViewHolder {
        public CardView rCardView;
        public RecyclerView recyclerView;
        public TitleView rTitleView;
        public ViewHolder(View itemView) {
            super(itemView);
            rCardView = (CardView) itemView.findViewById(R.id.reminder_card);
            rTitleView = (TitleView) itemView.findViewById(R.id.reminder_title);
            recyclerView = (RecyclerView) itemView.findViewById(R.id.checkbox_recycler_view);
        }
    }

    public RAdapter(List<Reminder> reminder, Context context, List<CheckBoxItem> checkBoxItems) {
        this.reminder = reminder;
        this.context = context;
        this.checkBoxItems = checkBoxItems;
    }

    @Override
    public RAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.reminder_card, parent, false);
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

    @Override
    public void onBindViewHolder(RAdapter.ViewHolder holder, int position) {
        lln = new LinearLayoutManager(context);
        holder.recyclerView.setLayoutManager(lln);
        checkBoxAdapter = new CAdapter(checkBoxItems, context);
        holder.recyclerView.setAdapter(checkBoxAdapter);
        holder.rCardView.setCardBackgroundColor(Color.parseColor("#00796b"));
        holder.rTitleView.setText(reminder.get(position).getReminderTitle());
    }

    @Override
    public int getItemCount() {
        return reminder.size();
    }
}

Und zweiter Adapter:

public class CAdapter extends RecyclerView.Adapter<CAdapter.ViewHolder> {
    List<CheckBoxItem> checkBoxItems;
    Context context;

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public TitleView checkBoxTitle;
        public ImageView deleteCheckBox;
        public CheckBox checkBoxCheckBox;

        public ViewHolder(View itemView) {
            super(itemView);
            checkBoxTitle = (TitleView) itemView.findViewById(R.id.checkbox_item_text);
            checkBoxCheckBox = (CheckBox) itemView.findViewById(R.id.checkbox_item_checkbox);
            Log.d("CAdapterLog", "Adpater Holded !!!!! :( ");
            deleteCheckBox = (ImageView) itemView.findViewById(R.id.btn_delete_checkbox);
        }
    }

    public CAdapter(List<CheckBoxItem> checkBoxItems, Context context) {
        this.checkBoxItems = checkBoxItems;
        this.context = context;
        Log.d("CAdapterLog", "Adpater Created !!!!! :( ");
    }


    @Override
    public CAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.checkbox_item, parent, false);
        ViewHolder vh = new ViewHolder(v);
        Log.d("CAdapterLog", "Adpater ViewHolded :( !!!!! :( ");
        return vh;
    }

    @Override
    public void onBindViewHolder(CAdapter.ViewHolder holder, int position) {
        Boolean isCheckboxChecked = Boolean.parseBoolean(checkBoxItems.get(position).getCheckBoxIsDone());
        String checkBoxText = checkBoxItems.get(position).getCheckBoxBody();
        Log.d("CAdapterLog", "Adpater Binded :( ");
        final int checkboxID = Integer.parseInt(checkBoxItems.get(position).getCheckBoxID());
        int reminderCheckBoxID = Integer.parseInt(checkBoxItems.get(position).getCheckBoxReminderID());
        holder.deleteCheckBox.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("CAdapterLog", "Cross Button Clicked !");
            }
        });
        holder.checkBoxCheckBox.setChecked(isCheckboxChecked);
        holder.checkBoxTitle.setText(checkBoxText);
    }

    @Override
    public int getItemCount() {
        return checkBoxItems.size();
    }

}

Und mein Problem: wie Sie in CAdapter sehen, nur das @ des KonstruktoLo Nachricht angezeigt.

AKTUALISIERE: Wenn es eine andere Möglichkeit gibt, einige dynamische Daten auf einer anderen dynamischen Karte anzuzeigen, wenn ja, ist es besser, sie anstelle von recyclerView zu verwenden?
jemand mir helfen?
Die Ausgabe :Application output Wie Sie sehen, funktioniert nur der setTitle für RAdapter.
