一、Context 對象獲取目錄

1）getExternalFilesDir

說(shuō)明

• 方法中的參數為需要在 files 目錄下新建的目錄名，如果新建的目錄不存在，則會(huì )創(chuàng )建，反之，不會(huì )重復創(chuàng )建。

示例

// args// Environment.DIRECTORY_MUSIC// Environment.DIRECTORY_PODCASTS// Environment.DIRECTORY_RINGTONES// Environment.DIRECTORY_ALARMS// Environment.DIRECTORY_NOTIFICATIONS// Environment.DIRECTORY_PICTURES// Environment.DIRECTORY_MOVIES// Environment.DIRECTORY_DOWNLOADS// Environment.DIRECTORY_DCIM// /storage/emulated/0/Android/data/cn.opensrc.enterpriseopenaccountsdktest/filesFile filePath1 = getExternalFilesDir("");// /storage/emulated/0/Android/data/cn.opensrc.enterpriseopenaccountsdktest/files/DCIMFile filePath2 = getExternalFilesDir(Environment.DIRECTORY_DCIM);// /storage/sdcard1/Android/data/cn.opensrc.enterpriseopenaccountsdktest/files/selfFile filePath3 = getExternalFilesDir("self");

2）getExternalCacheDir

說(shuō)明

• 新建 cache 目錄。

示例

// /storage/emulated/0/Android/data/cn.opensrc.enterpriseopenaccountsdktest/cacheFile filePath = getExternalCacheDir();

3）getCacheDir

示例

// /data/data/cn.opensrc.enterpriseopenaccountsdktest/cacheFile filePath = getCacheDir();

4）getDir

說(shuō)明

• 會(huì )新建名為 app_DirName 的目錄，其中 app_ 為固定格式。

示例

// /data/data/cn.opensrc.enterpriseopenaccountsdktest/app_MyFile filePath = getDir("My", MODE_PRIVATE);

5）getFilesDir

示例

// /data/data/cn.opensrc.enterpriseopenaccountsdktest/filesFile filePath = getFilesDir();

6）getObbDir

說(shuō)明

• 新建 obb 目錄。應用卸載時(shí)此目錄不會(huì )被卸載。
• obb 目錄主要用來(lái)存放 obb 文件，通常游戲會(huì )用。

示例

// /storage/emulated/0/Android/obb/cn.opensrc.enterpriseopenaccountsdktestFile filePath = getObbDir();

二、Environment 靜態(tài)方法獲取目錄

1）getExternalStorageDirectory

示例

// /storage/emulated/0File filePath = Environment.getExternalStorageDirectory();

2）getDataDirectory

示例

// /dataFile filePath = Environment.getDataDirectory();

3）getDownloadCacheDirectory

示例

// /cacheFile filePath = Environment.getDownloadCacheDirectory();

4）getExternalStoragePublicDirectory

說(shuō)明

• 返回的只是一個(gè)目錄路徑，而此路徑目錄并沒(méi)有被創(chuàng )建。

示例

// args:// Environment.DIRECTORY_MUSIC// Environment.DIRECTORY_PODCASTS// Environment.DIRECTORY_RINGTONES// Environment.DIRECTORY_ALARMS// Environment.DIRECTORY_NOTIFICATIONS// Environment.DIRECTORY_PICTURES// Environment.DIRECTORY_MOVIES// Environment.DIRECTORY_DOWNLOADS// Environment.DIRECTORY_DCIM// /storage/emulated/0File filePath1 = Environment.getExternalStoragePublicDirectory("");// /storage/emulated/0/DownloadFile filePath2 = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);// /storage/emulated/0/sharpFile filePath3 = Environment.getExternalStoragePublicDirectory("sharp");

5）getRootDirectory

示例

// /systemFile filePath = Environment.getRootDirectory();

6）getExternalStorageState

示例

// return:// Environment.MEDIA_UNKNOWN// Environment.MEDIA_REMOVED// Environment.MEDIA_UNMOUNTED// Environment.MEDIA_CHECKING// Environment.MEDIA_NOFS// Environment.MEDIA_MOUNTED// Environment.MEDIA_MOUNTED_READ_ONLY// Environment.MEDIA_SHARED// Environment.MEDIA_BAD_REMOVAL// Environment.MEDIA_UNMOUNTABLEString state = Environment.getExternalStorageState();

注意

1. 當應用安裝后，系統自動(dòng)會(huì )創(chuàng )建 內部存儲/Android/應用包名目錄，默認這個(gè)以包名命名的目錄下會(huì )創(chuàng )建一個(gè)files目錄。當應用卸載時(shí)，這個(gè)以包名命名的目錄也會(huì )被刪除。
2. /sdcard == Environment.getExternalStorageDirectory( ) == Environment.getExternalStoragePublicDirectory("")
