我有一个包含很多文件的目录.我想删除整个目录以及其中的所有文件.
我希望我的代码等到该目录中的每个文件(包括目录本身)在执行下一个命令之前被删除.
我怎么等 我的代码是
public void wipeMemoryCard()
{
File deleteMatchingFile = new File(Environment
.getExternalStorageDirectory().toString());
try {
filenames = deleteMatchingFile.listFiles();
if (filenames != null && filenames.length > 0)
{
content = true;
for (File tempFile : filenames)
{
if (tempFile.isDirectory())
{
wipeDirectory(tempFile.toString());
tempFile.delete();
}
else
{
File file = new File(tempFile.getAbsolutePath());
file.delete();
}
}
}
else
{
deleteMatchingFile.delete();
Toast("No files to Delete");
}
}
catch (Exception e)
{
e.printStackTrace();
}
if(content == true)
{
if (filenames == null && filenames.length == 0)
{
Toast("Files Deleted");
}
}
}
private static void wipeDirectory(String name) {
File directoryFile = new File(name);
File[] filenames = directoryFile.listFiles();
if (filenames != null && filenames.length > 0)
{
for (File tempFile : filenames)
{
if (tempFile.isDirectory())
{
wipeDirectory(tempFile.toString());
tempFile.delete();
}
else
{
File file = new File(tempFile.getAbsolutePath());
file.delete();
}
}
} else
{
directoryFile.delete();
}
}
