"Android Notes" Android Stats folder size, delete all file methods under folder

1. Get the folder size:

1 /**   2 * Get folder size3      * @paramFile File Instance4      * @returnLong5      */     6      Public Static Longgetfoldersize (Java.io.File File) {7    8         LongSize = 0; 9         Try {  Tenjava.io.file[] FileList =File.listfiles ();  One              for(inti = 0; i < filelist.length; i++)      A             {      -                 if(Filelist[i].isdirectory ()) -                 {      theSize = size +getfoldersize (Filelist[i]);  -     -}Else{      -Size = size +filelist[i].length ();  +     -                 }      +             }   A}Catch(Exception e) { at             //TODO auto-generated Catch block - E.printstacktrace ();  -         }      -        //return size/1048576;  -         returnsize;  -}

2. Delete all files under folder:

1 /**   2 * Delete files and directories in the specified directory3      * @paramDeletethispath4      * @paramfilepath5      * @return    6      */     7      Public voidDeletefolderfile (String FilePath,BooleanDeletethispath) {     8         if(!Textutils.isempty (FilePath)) {     9             Try {  TenFile File =NewFile (FilePath);  One                 if(File.isdirectory ()) {//Working with Catalogs AFile files[] =File.listfiles ();  -                      for(inti = 0; i < files.length; i++) {      -Deletefolderfile (Files[i].getabsolutepath (),true);  the                     }       -                 }      -                 if(Deletethispath) { -                     if(!file.isdirectory ()) {//if it is a file, delete + File.delete ();  -}Else{//Catalogue +                    if(File.listfiles (). Length = = 0) {//there is no file or directory under the directory, delete A File.delete ();  at                         }      -                     }      -                 }   -}Catch(Exception e) { -                 //TODO auto-generated Catch block - E.printstacktrace ();  in             }      -         }      to}

3. Format Folder size unit:

1 /** 2 * Formatted units3      * @paramsize4      * @return 5      */  6      Public StaticString Getformatsize (Doublesize) {  7         Doublekilobyte = size/1024; 8         if(Kilobyte < 1) {  9             returnSize + "B"; Ten         }   One            A         Doublemegabyte = kilobyte/1024;  -         if(Megabyte < 1) {   -BigDecimal RESULT1 =NewBigDecimal (double.tostring (kilobyte));  the             returnResult1.setscale (2, bigdecimal.round_half_up). Toplainstring () + "KB";  -         }   -            -         DoubleGigaByte = megabyte/1024;  +         if(GigaByte < 1) {   -BigDecimal RESULT2 =NewBigDecimal (double.tostring (megabyte));  +             returnResult2.setscale (2, bigdecimal.round_half_up). Toplainstring () + "MB";  A         }   at            -         Doubleterabytes = gigabyte/1024;  -         if(Terabytes < 1) {   -BigDecimal RESULT3 =NewBigDecimal (double.tostring (gigaByte));  -             returnResult3.setscale (2, bigdecimal.round_half_up). Toplainstring () + "GB";  -         }   inBigDecimal RESULT4 =NewBigDecimal (terabytes);  -         returnResult4.setscale (2, bigdecimal.round_half_up). Toplainstring () + "TB";  to}
