Fragment内にListViewを配置しているのですが、Android4.x環境で以下のエラーが発生します(Android6.xでは問題なし)。解決法を探しても似た事例が見つかりませんでした。よろしくお願いします。

CustomAdapterのコードは以下です。

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

import java.util.List;

public class CustomAdapter extends ArrayAdapter<Article> {
    private LayoutInflater layoutInflater_;
    Context context;
    List<Article> articles;

    public CustomAdapter(Context context, int textViewResourceId, List<Article> objects) {
        super(context, textViewResourceId, objects);
        this.context = context;
        this.articles = objects;
        layoutInflater_ = LayoutInflater.from(context);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        Article item = articles.get(position);

        // convertViewがnullの時のみ作成
        if (v == null) {
            v = layoutInflater_.inflate(R.layout.row, null); //←ここでエラー
        }

        TextView textView = (TextView)convertView.findViewById(R.id.textView2);
        textView.setText(item.getTitle());

        TextView textView1 = (TextView)convertView.findViewById(R.id.textView3);
        textView1.setText(item.getSite());

        TextView textView2 = (TextView)convertView.findViewById(R.id.textView4);
        textView2.setText(item.getDate());

        return v;
    }
}
