Ich plane, eine App zu entwickeln, die einige dynamische Daten in einem recyclerCardView
zeigt. Also entschied ich, fügen Sie eine recyclerView
namens CheckBoxRecyclerView
in meinem Haupt recyclerView
. Dies ist mein Code für meine App:So fügen Sie eine RecyclerView in einem anderen RecyclerView hinzu
Meine Haupttätigkeit:
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 das 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 diesem recyclerView es eine andere ist:
<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 zweiten 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 Log Nachricht Konstruktor angezeigt.
UPDATE: Wenn es eine andere Möglichkeit gibt, einige dynamische Daten in einer anderen dynamischen Karte anzuzeigen, wenn ja, ist es besser, sie anstelle von recycleView zu verwenden?
jemand mir helfen?
Die Ausgabe: Application output wie Sie sehen, nur die SetTitle für RAdapter funktioniert.
Versuchen Sie, die [ExpandableListView] (http://developer.android.com/intl/es/reference/android/widget/ExpandableListView.html) neu zu erfinden? –
Meine Liste Daten ist nicht erweiterbar. Ich denke, das Problem ist von meinem Adapter, aber weiß nicht, was ist das Problem? –
Sie wollen Recyclerview in anderen Recyclerview einfach Ihre Lösung mehr das ist nicht gut für die Leistung – sector11
