* 方法：getDataDirectory()解释：返回 File ，获取 Android 数据目录。* 方法：getDownloadCacheDirectory()解释：返回 File ，获取 Android 下载/缓存内容目录。* 方法：getExternalStorageDirectory()解释：返回 File ，获取外部存储目录即 SDCard* 方法：getExternalStoragePublicDirectory(String type)解释：返回 File ，取一个高端的公用的外部存储器目录来摆放某些类型的文件* 方法：getExternalStorageState()解释：返回 File ，获取外部存储设备的当前状态* 方法：getRootDirectory()解释：返回 File ，获取 Android 的根目录public void getSDPath(){ File sdDir = null; File sdDir1 = null;File sdDir2 = null;boolean sdCardExist = Environment.getExternalStorageState() .equals(android.os.Environment.MEDIA_MOUNTED); //判断sd卡是否存在 if (sdCardExist) { sdDir = Environment.getExternalStorageDirectory();//获取跟目录 sdDir1 = Environment.getDataDirectory();sdDir2 =Environment.getRootDirectory();} System.out.println("getExternalStorageDirectory(): "+sdDir.toString()); System.out.println("getDataDirectory(): "+sdDir1.toString()); System.out.println("getRootDirectory(): "+sdDir2.toString()); } //判断一个路径下的文件（文件夹）是否存在public class IsExist {public static void main(String[] args) {isExist("e://12");}/*** * @param path 文件夹路径*/public static void isExist(String path) {File file = new File(path);//判断文件夹是否存在,如果不存在则创建文件夹if (!file.exists()) {file.mkdir();}}}

public class make extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); File sd=Environment.getExternalStorageDirectory(); String path=sd.getPath()+"/notes"; File file=new File(path); if(!file.exists()) file.mkdir(); }
