有没有什么功能/方法，它允许检测各种不同的存储到您的手机与他们的名字。我的意思是，检测所有内部/外部存储如果您的设备上的多个。以及如何检测是否有可用SD卡或不？

推荐答案

我不知道其他类型的存储设备，我只知道内部存储和外部存储的Andr​​oid设备。

I don't know about other types of storage device, I only know Internal Storage and External Storage device for android.

现在可用的检查外部存储类似，

public static boolean isSdPresent() {

return android.os.Environment.getExternalStorageState().equals(
android.os.Environment.MEDIA_MOUNTED);

}

return type boolean(true->available,false->NA).

和对于内部存储，（内部存储始终保持（present），所以没有必要检查）刚刚获得像，

And for Internal storage, (Internal storage is always remain (present) so no need to check it) just get like,

File path = Environment.getDataDirectory();

现在，在这两种情况下，检查可用内存和使用的内存，

Now, in both case to check available free memory and usage memory,

StatFs stat = new StatFs(path.getPath());
long blockSize = stat.getBlockSize();
long availableBlocks = stat.getAvailableBlocks();
return Formatter.formatFileSize(this, availableBlocks * blockSize);
