Java ListView自定义适配器位置卡在0处
我正在跟踪此ListView，但我的ListViewJava ListView自定义适配器位置卡在0处,java,android,android-listview,Java,Android,Android Listview,我正在跟踪此ListView，但我的ListViewlistVThisMonthRecords卡在0位置，它只打印出ArrayListthisMonthRecords的第一项。ArrayListthisMonthRecords中有3个记录对象 我已经设置了调试日志，以了解CustomAdapter中发生了什么，下面是输出。看起来thismonthrocrds已正确传递，其中包含3项，但问题是每次调用CustomAdapter中的getView（）时，该位置每次都卡在0处。我不知道如何解决这个问
