android : 폴더 이름을 얻는 방법

Question

BUCKET_LIST_NAME을 (를) 사용하여 모든 폴더와 폴더 이름을 표시하는 클래스 어댑터가 있습니다. 그러나 폴더는 같은 이름 = 사진을 가지고 있습니다. 다른 이름을 얻는 방법, 나는 각 폴더의 진짜 이름을 얻는 방법을 의미한다 ??? 감사.

public class ThumbnailAdapter extends BaseAdapter { 

// Context required for performing queries 
private final Context mContext; 

// Cursor for thumbnails 
private final Cursor cursor; 

private final int count; 

String bucket; 
String id; 


public ThumbnailAdapter(Context c) { 
    this.mContext = c; 

    // Get list of all images, sorted by last taken first 
    final String[] projection = { 
      MediaStore.Images.Media.BUCKET_ID, 
      MediaStore.Images.Media.BUCKET_DISPLAY_NAME 
    }; 
    String BUCKET_GROUP_BY = 
      "1) GROUP BY 1,(2"; 
    String BUCKET_ORDER_BY = "MAX(datetaken) DESC"; 

    cursor = mContext.getContentResolver().query(
      MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
      projection, 
      BUCKET_GROUP_BY, 
      null, 
      BUCKET_ORDER_BY 
    ); 
    if (cursor.moveToFirst()) { 

     int bucketColumn = cursor.getColumnIndex(
       MediaStore.Images.Media.BUCKET_DISPLAY_NAME); 

     int idColumn = cursor.getColumnIndex(
       MediaStore.Images.Media.BUCKET_ID); 


     do { 
      // Get the field values 
      bucket = cursor.getString(bucketColumn); 
      id = cursor.getString(idColumn); 


     } while (cursor.moveToNext()); 
    } 

    count = cursor.getCount(); 
    Log.d("ThumbnailAdapter", count + " images found"); 
} 

@Override 
public int getCount() { 
    return count; 
} 

@Override 
public Object getItem(int position) { 
    return position; 
} 

@Override 
public long getItemId(int position) { 
    return position; 
} 


@Override 
public View getView(int position, View convertView, ViewGroup parent) { 

     LinearLayout ll = new LinearLayout(mContext); 

     ImageView imageView = new ImageView(mContext); 
     TextView mytext = new TextView(mContext); 
    mytext.setText(bucket); 
     imageView.setImageResource(R.drawable.your_folder_icon); 
     ll.addView(imageView); 
     ll.addView(mytext); 



    return ll; 
}

는 커서를 초기화 :이와 어댑터에

final String[] projection = { 
      MediaStore.Images.Media.BUCKET_ID, 
      MediaStore.Images.Media.BUCKET_DISPLAY_NAME 
    }; 
    String BUCKET_GROUP_BY = 
      "1) GROUP BY 1,(2"; 
    String BUCKET_ORDER_BY = "MAX(datetaken) DESC"; 

    cursor = mContext.getContentResolver().query(
      MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
      projection, 
      BUCKET_GROUP_BY, 
      null, 
      BUCKET_ORDER_BY 
    ); 

패스 :

CursorAdapter adapter = ThumbnailAdapter(mContext, cursor); 

어댑터 클래스 :

public class ThumbnailAdapter extends CursorAdapter 
{ 
    LayoutInflater mInflater; 
    Context context; 
    Cursor cursor; 
    String bucket; 
    String id; 

    public ThumbnailAdapter(Context context, Cursor c) 
    { 
     super(context, c); 
     this.context = context; 
     this.cursor = c; 
     mInflater = LayoutInflater.from(context); 
    } 
    @Override 
    public void bindView(View view, Context context, Cursor cursor) 
    { 
     TextView mytext = (TextView) view.findViewById(R.id.mytext); 
     ImageView imageView = (ImageView) view.findViewById(R.id.imageView); 

     mytext.setText(bucket); 
     imageView.setImageResource(R.drawable.your_folder_icon); 
    } 
    @Override 
    public View newView(Context arg0, Cursor arg1, ViewGroup arg2) 
    { 
     View v = mInflater.inflate(R.layout.checklistitem_withbutton, null); // Your XML View. 
     return v; 
    } 
}
