java中删除特定后缀名文件

String path = Environment.getExternalStorageDirectory()
.getPath() + AppConstant.FILE_PATH + "/" + apkName ;
File file = new File(path);
deleteApk(path);

/**
* 删除其他版本安装包
*/
public void deleteApk(String abpath) {
String[] ss = abpath.split("/");
String name = ss[ss.length - 1];
String path = abpath.replace("/" + name, "");

File file = new File(path);// 里面输入特定目录
File temp = null;
File[] filelist = file.listFiles();
for (int i = 0; i < filelist.length; i++) {
temp = filelist[i];
if (temp.getName().endsWith("apk") && !temp.getName().endsWith(name))// 获得文件名，如果后缀为“”，这个你自己写，就删除文件
{
temp.delete();// 删除文件}
}
}
