如何进入Android Studio自定义listView中的某一项？

public class CustomListAdapter extends ArrayAdapter<String> {
    private Context mContext;
    private List<String> mList;

    public CustomListAdapter(Context context, List<String> list) {
        super(context, 0, list);
        mContext = context;
        mList = list;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.list_item, parent, false);
        }

        TextView textView = convertView.findViewById(R.id.text_view);
        textView.setText(mList.get(position));

        convertView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 用户点击了某一项
                // 执行相应的操作，例如打开一个新的Activity
                Intent intent = new Intent(mContext, DetailActivity.class);
                intent.putExtra("position", position);
                mContext.startActivity(intent);
            }
        });

        return convertView;
    }
}
