Android 自定义适配器上的NullPointerException

我遇到了一个无法解决的错误

这是我的密码：

私有类MyAdapter扩展了ArrayAdapter {

下面是日志：

更改返回语句

返回行

作为return super.getView（position，convertView，parent）；包含covertView，它为空并引发空指针异常。

我替换了return语句，但仍然得到空指针异常。****************************************************************************************************************************************************************************04-27 13:33:23.574:E/AndroidRuntime（22501）：致命异常：main 04-27 13:33:23.574:E/AndroidRuntime（22501）：java.lang.nullpointer异常04-27 13:33:23.574:E/AndroidRuntime（22501）：在com.fsd.fashioner.main菜单$MyAdapter.getView（main menu.java:51）04-27 13:33:23.574:E/AndroidRuntime（22501）：在android.widget.AbsListView.obtainView（AbsListView.java:2461）04-27 13:33:23.574***************************************但现在错误在第51行注释这些行并检查它：tv.setText（items[position].getFName（）+“”+items[position].getName（）；Log.w（“myApp”，tv.getText（）.toString（））；
