I got this here from SO, I'm sorry I forgot the author (credits to him) but if you want to make/customize your own function, do this.
我是从 SO 那里得到的，很抱歉我忘记了作者（归功于他）但是如果您想制作/自定义您自己的功能，请执行此操作。
private boolean delete(File pFile) {
boolean bResult = false;
if(pFile.exists()) {
if(pFile.isDirectory()) {
if(pFile.list().length == 0) {
pFile.delete();
} else {
String[] strFiles = pFile.list();
for(String strFilename: strFiles) {
File fileToDelete = new File(pFile, strFilename);
delete(fileToDelete);
}
}
} else {
pFile.delete();
}
}
return bResult;
}
