我想用2个文本框来定制ListView，当我首先显示号码时，我可以显示其未接来电号码，已接或外拨号码，以及日期，我可以在ListView的第二行中显示日期和通话类型，但是当我尝试时显示数字会产生以下错误。

在这里，我已经将List转换为String []，但是如果我写的话，我就能得到输出
lviewAdapter = new ListViewAdapter(this, timeArray, timeArray);其中都打印呼叫类型和日期，但当我写lviewAdapter = new ListViewAdapter(this, timeArray, timeArray);它给出了ArrayIndexoutOfBoundException

最佳答案
上面的代码运行良好，我只需将其复制并粘贴并运行此代码即可获得以下结果。
