I trying to create a ListView in a Fragment within a ViewPager in a AppCompatActivity. In the AppCompatActivity are all view elements are wrappend in a CoordinatorLayout. Because I used the CoordinatorLayout. I have to use a RecylerView I am trying to follow the training from developer.android.com, but my application stopped after my log. This is my code in myFragment where the applications stopped.
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
//...
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_city_list, container, false)
mRecyclerView = (RecyclerView) view.findViewById(android.R.id.list);
mLayoutManager = new LinearLayoutManager(this.getActivity());
Log.d("debugMode", "The application stopped after this");
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new RecyclerAdapter(getNames());
mRecyclerView.setAdapter(mAdapter);
return view;
}
//...
Use this
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_city_list, container, false)
// Replace 'android.R.id.list' with the 'id' of your RecyclerView
mRecyclerView = (RecyclerView) view.findViewById(android.R.id.list);
mLayoutManager = new LinearLayoutManager(this.getActivity());
Log.d("debugMode", "The application stopped after this");
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new RecyclerAdapter(getNames());
mRecyclerView.setAdapter(mAdapter);
return view;
}
You should call the setLayoutManager
& setAdapter
methods (respectively) on the Recyclerview
.
Plus,
mRecyclerView = (RecyclerView) view.findViewById(android.R.id.list);
you should not use android.R.id.list
, as you're not using a ListFragment
. Replace it with the id
of you Recyclerview
(as in your XML layout).
