我在 logcat 中收到错误“未连接适配器；跳过布局”。但是在我的手机上显示似乎没有问题。我想知道是什么导致了错误。
提前致谢。
OnCreate 方法:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_appbar);
context=this;
toolbar=(Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
NavFragment drawerFragment = (NavFragment)
getSupportFragmentManager().findFragmentById(R.id.nav_frag);
drawerFragment.setUp(R.id.nav_frag, (DrawerLayout) findViewById(R.id.drawerLayout), toolbar);
listEvents= new ArrayList<>();
Parse.enableLocalDatastore(this);
Parse.initialize(this, "xxxxxxxxxx", "xxxxxxxxxxx");
//TEST PARSE
ParseQuery<ParseObject> query = ParseQuery.getQuery("Test");
//query.whereEqualTo("playerName", "Dan Stemkoski");
query.findInBackground(new FindCallback<ParseObject>() {
public void done(List<ParseObject> eventList, ParseException e) {
if (e == null) {
Log.d("Events", "Retrieved " + eventList.size() + " Events");
for (int i = 0; i < eventList.size(); i++) {
Events events = new Events();
events.setTitle((String) eventList.get(i).get("teststr"));
events.setId(String.valueOf(eventList.get(i).get("teststr")));
listEvents.add(events);
}
eventAdapter= new EventAdapter(context);
eventAdapter.setEventList(listEvents);
eventsList.setAdapter(eventAdapter);
} else {
Log.d("score", "Error: " + e.getMessage());
}
}
});
eventsList=(RecyclerView)findViewById(R.id.list_events);
eventsList.setLayoutManager(new LinearLayoutManager(this));
}
事件适配器:
public class EventAdapter extends RecyclerView.Adapter<EventAdapter.ViewHolderEvents> {
private LayoutInflater layoutInflater;
private ArrayList<Events> listEvents= new ArrayList<>();
public EventAdapter(Context context){
layoutInflater=LayoutInflater.from(context);
}
public void setEventList(ArrayList<Events> listEvents){
this.listEvents=listEvents;
notifyItemRangeChanged(0,listEvents.size());
}
@Override
public ViewHolderEvents onCreateViewHolder(ViewGroup viewGroup, int i) {
View view=layoutInflater.inflate(R.layout.custom_event_row,viewGroup,false);
ViewHolderEvents viewHolder =new ViewHolderEvents(view);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolderEvents viewHolderEvents, int i) {
Events currentEvent= listEvents.get(i);
viewHolderEvents.title.setText(currentEvent.getTitle());
viewHolderEvents.id.setText(currentEvent.getId());
}
@Override
public int getItemCount() {
return listEvents.size();
}
static class ViewHolderEvents extends RecyclerView.ViewHolder{
private TextView title;
private TextView id;
public ViewHolderEvents(View itemView) {
super(itemView);
title=(TextView)itemView.findViewById(R.id.title);
id=(TextView)itemView.findViewById(R.id.description);
}
}
