如何更改SD卡保存到的默認文件夾？

Question

我的應用程序當前保存到我指定的文件夾/Pictures/<app_name>/，但它也保存到默認文件夾/DCIM/Camera/。這導致文件被保存到SD卡兩次，但在不同的文件夾中。我如何製作它，因此它不會將它保存到兩個文件夾，只有我指定的文件夾？

我剛纔添加的解決方案，以避免如果鏈接的頁面變化的無效答案。

檢查下面的代碼：

private void FillPhotoList() { 
    // initialize the list!  
    GalleryList.clear();  
    String[] projection = { MediaStore.Images.ImageColumns.DISPLAY_NAME }; 
    for(int i=0;i<projection.length;i++) 
     Log.i("InfoLog","projection "+projection[0].toString()); 
    // intialize the Uri and the Cursor, and the current expected size.  
    Cursor c = null;  
    Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI; 
    Log.i("InfoLog","FillPhoto Uri u "+u.toString()); 
    // Query the Uri to get the data path. Only if the Uri is valid.  
    if (u != null)  
    {  
     c = managedQuery(u, projection, null, null, null);  
    }  
    // If we found the cursor and found a record in it (we also have the id).  
    if ((c != null) && (c.moveToFirst()))  
    {  
     do   
     {   
      // Loop each and add to the list.   
      GalleryList.add(c.getString(0)); // adding all the images sotred in the mobile phone(Internal and SD card) 

     }    
     while (c.moveToNext());  
    } 
    Log.i(INFOLOG,"gallery size "+ GalleryList.size()); 
} 

而這正是該方法是做所有的魔法

/** Method will check all the photo is the gallery and delete last captured and move it to the required folder. 
*/ 
public void movingCapturedImageFromDCIMtoMerchandising() 
{ 

    // This is ##### ridiculous. Some versions of Android save   
    // to the MediaStore as well. Not sure why! We don't know what   
    // name Android will give either, so we get to search for this   
    // manually and remove it.   
    String[] projection = { MediaStore.Images.ImageColumns.SIZE, 
      MediaStore.Images.ImageColumns.DISPLAY_NAME, 
      MediaStore.Images.ImageColumns.DATA, 
      BaseColumns._ID,}; 
    // intialize the Uri and the Cursor, and the current expected size. 

    for(int i=0;i<projection.length;i++) 
     Log.i("InfoLog","on activityresult projection "+projection[i]); 
    //+" "+projection[1]+" "+projection[2]+" "+projection[3] this will be needed if u remove the for loop 
    Cursor c = null;   
    Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;  
    Log.i("InfoLog","on activityresult Uri u "+u.toString()); 

    if (CurrentFile != null)  
    {       
     // Query the Uri to get the data path. Only if the Uri is valid,  
     // and we had a valid size to be searching for.  
     if ((u != null) && (CurrentFile.length() > 0))   
     {    
      //****u is the place from data will come and projection is the specified data what we want 
      c = managedQuery(u, projection, null, null, null);  
     }

         try

          CurrentFile.createNewFile();  
          FileChannel source = null; 
          FileChannel destination = null; 
          try

           destination = new FileOutputStream(CurrentFile).getChannel(); 
           destination.transferFrom(source, 0, source.size()); 
          } 
          finally      
          { 
           if (source != null)

           }

         }       
         catch (IOException e)     
         {        
          // Could not copy the file over.  
          ToastMaker.makeToast(this, "Error Occured", 0);

對於Android的薑餅版本2.3.3，您可以更改攝像頭默認保存位置。啓動相機應用程序，單擊設置（cog），單擊扳手選項卡，向下滾動，然後選擇存儲卡。更改爲存儲卡（與內部存儲器相比）。
