如何从扩展BaseAdapter的类启动一个Activity？

Question

我使用以下代码生成自定义ListView.一切都运行正常,但是当用户点击列表视图时,我无法转到另一个类,因为Intents不能在非Activity类中使用.有没有办法为下面的代码启动一个活动???

public class CustomAdapter extends BaseAdapter  {
String[] result;
Context context;
int[] imageId;
private static LayoutInflater inflater = null;

public CustomAdapter(MainActivityList mainActivity, String[] prgmNameList,
        int[] prgmImages) {
    // TODO Auto-generated constructor stub
    result = prgmNameList;
    context = mainActivity;
    imageId = prgmImages;
    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return result.length;
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return position;
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}

public class Holder {
    TextView tv;
    ImageView img;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    Holder holder = new Holder();
    View rowView;
    rowView = inflater.inflate(R.layout.program_list, null);
    holder.tv = (TextView) rowView.findViewById(R.id.textViewlist);
    holder.img = (ImageView) rowView.findViewById(R.id.imageViewlist);
    holder.tv.setText(result[position]);
    holder.img.setImageResource(imageId[position]);

    rowView.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            switch(position)
            {
            case 0:
            {
                //Intent is not working here
                                    //Here i need some help 
            }
            }
        }
    });
    return rowView;
}

}

我被困在项目的这一部分,请帮帮我..

使用活动上下文

Intent intent = new Intent(context,AnotherActivity.class);
context.startActivity(intent);
