java - Android ArrayAdapter 未定义

Question

我在创建 Listview 适配器时遇到问题，这是代码。

import com.actionbarsherlock.app.SherlockFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class Recipes extends SherlockFragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        ListView recipelist = (ListView) getView().findViewById(R.id.recipe_drawer);

        String[] items ={ getResources().getString(R.string.block),
        getResources().getString(R.string.tool),
        getResources().getString(R.string.support),
        getResources().getString(R.string.veggie)
        };

        ArrayAdapter<String> adapt = new ArrayAdapter<String>(Recipes.this, R.layout.recipes_list_item, items);
        recipelist.setAdapter(adapt);

        View rootView = inflater.inflate(R.layout.recipes, container, false);
        return rootView;


    }

}

我得到的错误位于 ArrayAdapter<String> adapt = new ArrayAdapter<String>(Recipes.this, R.layout.recipes_list_item, items);它说

The constructor ArrayAdapter(Recipes,int,String[]); is undefined.

我尝试将 Recipes.this 更改为这个，但仍然遇到相同的错误。任何帮助，将不胜感激!

将Recipes.this更改为getActivity()。您处于 Fragment 中，它不是 Context，而 Context 是 ArrayAdapter 系列构造函数的第一个参数。
