Question

我已经阅读了有关此主题的其他问题，但我找不到解决方案，因为没有任何对我有用。

我正在尝试获取总设备磁盘空间，无论它是空闲还是忙碌。当您看到设备规范时，会出现＆＃34;存储＆＃34;通常为64GB，32GB或8GB的项目，表示整个设备存储。

到目前为止，我的代码是：

private static String floatForm(double d) {
    return new DecimalFormat("#.##").format(d);
}

@NonNull
private static String bytesToHuman(long size) {
    long Kb = 1024;
    long Mb = Kb * 1024;
    long Gb = Mb * 1024;
    long Tb = Gb * 1024;
    long Pb = Tb * 1024;
    long Eb = Pb * 1024;

    if (size <  Kb)                 return floatForm(size) + " Bytes";
    if (size >= Kb && size < Mb)    return floatForm((double) size / Kb) + " KB";
    if (size >= Mb && size < Gb)    return floatForm((double) size / Mb) + " MB";
    if (size >= Gb && size < Tb)    return floatForm((double) size / Gb) + " GB";
    if (size >= Tb && size < Pb)    return floatForm((double) size / Tb) + " TB";
    if (size >= Pb && size < Eb)    return floatForm((double) size / Pb) + " PB";
    if (size >= Eb)                 return floatForm((double) size / Eb) + " EB";
    return "???";
}


static public String totalSpace() {
    long availableBytes = 0;

    StatFs root = new StatFs(Environment.getRootDirectory().getPath());
    StatFs data = new StatFs(Environment.getDataDirectory().getPath());


    availableBytes += root.getBlockCountLong() * root.getBlockSizeLong();
    availableBytes += data.getBlockCountLong() * data.getBlockSizeLong();

    return bytesToHuman(availableBytes);
}

在我的OnePlus 5（128GB）上，它返回114,17GB，在我的三星J5（8GB）6,65GB上。它总是缺少10-20％的大小

我如何修复此代码？

Answer 1

public static long getTotalInternalMemorySize() {
    final File path = Environment.getDataDirectory();
    final StatFs stat = new StatFs(path.getPath());
    final long blockSize = stat.getBlockSize();
    final long totalBlocks = stat.getBlockCount();

    long sizeInMb =  totalBlocks * blockSize / (1024 * 1024);
    return sizeInMb;
}

Try this. If not suitable for you let me know. Thanks
