从sdcard到listview创建了两个文件名和时间的文本视图

从sdcard到listview创建了两个文件名和时间的文本视图,listview,datetime,android-listview,arraylist,adapter,Listview,Datetime,Android Listview,Arraylist,Adapter,我的应用程序是我录制声音并在列表中显示录制文件的地方。我想创建一个包含两个文本视图的列表视图。我从sd卡中指定一个文件夹,其中包含我使用应用程序录制的音频文件,并在列表视图中显示这些文件。列表中的第一个文本视图是文件名,第二个文本是创建的时间或日期。我不知道如何在名单上加上时间 我的代码如下 public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); set
