How to get files in cache directory in android?
提问by omega
In my android app, I make files in a directory I get using this function (notice its putting in a subdirectory).
在我的 android 应用程序中，我在使用此函数的目录中创建文件（注意它放在子目录中）。
gsFile = new File(getCacheDir(), "test/aa.txt");
But how do I iterate through the files in that directory now?
但是我现在如何遍历该目录中的文件？
I tried
我试过
File dir = new File(getCacheDir(), "test/aa.txt");
for (File f : dir.listFiles()) {
}
but it crashed on File f
但它在文件 f 上崩溃了

Using the below code you can get all the files which are there in your app's cache directory and you can iterate over it and perform whatever is required
使用下面的代码，您可以获得应用程序缓存目录中的所有文件，您可以对其进行迭代并执行所需的任何操作
File dir = new File(mContext.getCacheDir().getAbsolutePath());
if (dir.exists()) {
for (File f : dir.listFiles()) {
f.getName();
}
}
