我有一个工作的导航抽屉,使用文档中ArrayAdapter所示.我想为每个导航抽屉项设置图标,所以我需要创建一个自定义适配器来使用,但我不确定如何做到这一点.我在下面运行而不会崩溃应用程序,但导航抽屉打开空,没有任何内容.你能帮帮我吗？提前致谢!ImageView

到目前为止我为自定义适配器做了什么:

public class CustomAdapter extends ArrayAdapter
{
    private final Context context;

    public CustomAdapter(Context context)
    {
       super(context, R.layout.drawer_list_item);
       this.context = context;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View v = inflater.inflate(R.layout.drawer_list_item, parent, false);
        TextView textViewHome = (TextView) v.findViewById(R.id.drawerHomeTextView);
        ImageView imageViewHome = (ImageView) v.findViewById(R.id.drawerHomeImage);
        TextView textViewList = (TextView) v.findViewById(R.id.drawerListTextView);
        ImageView imageViewList = (ImageView) v.findViewById(R.id.drawerListImage);

        return v;
    }
}

设置抽屉MainActivity:

mDrawerList = (ListView) findViewById(R.id.leftDrawer);

mDrawerList.setAdapter(new CustomAdapter(this)); …
