Android开发实现的获取sdcard大小及内存大小工具类

本文实例讲述了Android开发实现的获取sdcard大小及内存大小工具类。分享给大家供大家参考，具体如下：

public class SDCardUtil {
  
  public static void getSDCardInfo(Context context){
    try {
      File path = Environment.getExternalStorageDirectory();
      StatFs s = new StatFs(path.getPath());
      long availableBlocks = s.getAvailableBlocksLong();
      long blockCount = s.getBlockCountLong();
      long blockSize = s.getBlockSizeLong();
      long totalsize = blockSize * blockCount;
      long availsize = blockSize * availableBlocks;
      String totalsizeStr = Formatter.formatFileSize(context, totalsize);
      String availsizeStr = Formatter.formatFileSize(context, availsize);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
  
  public static void getDataInfo(Context context){
    try {
      File path = Environment.getDataDirectory();
      StatFs s = new StatFs(path.getPath());
      long availableBlocks = s.getAvailableBlocksLong();
      long blockCount = s.getBlockCountLong();
      long blockSize = s.getBlockSizeLong();
      long totalsize = blockSize * blockCount;
      long availsize = blockSize * availableBlocks;
      String totalsizeStr = Formatter.formatFileSize(context, totalsize);
      String availsizeStr = Formatter.formatFileSize(context, availsize);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}
