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 {
/**
* SD卡
* @param context
*/
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();
}
}
/**
* 手机内存
* @param context
*/
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();
}
}
}
