Question

我正在尝试在片段中实现列表视图。但是当我启动应用程序时它会崩溃。这是HomeFragment.java类的代码

package info.nadimemon.slidingmenu;
import android.app.Fragment;
import android.app.ListFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class HomeFragment extends ListFragment {

public HomeFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_home, container, false);


    String[] adobe_products = getResources().getStringArray(R.array.adobe_products);
    this.setListAdapter(new ArrayAdapter<String>(getActivity(), R.layout.fragment_home, R.id.label, adobe_products));


    return rootView;
}

}

这是我的logcat
