Android Scan SCard Card all pictures

1. These days in order to scan all the pictures of SCard card is very tangled, I originally thought this is a very simple thing, but I found that I was wrong. There is no complete code on the web, just bits and pieces of code that can scan a single file. After today's code debugging passed, I think I need to share with you.
   1, because the mobile phone side of the scan, so it is best to open a thread. It is very important to have the scan done in a sub-thread, so start looking at this class now! This code can scan out all the files on the SCard card.

2. Public class Getfilepaththread implements Runnable {
   
4. 
   
6. Public String pathstring;
   
8. Public List < String > listpath;
   
10. Public Getfilepaththread(string path,List<string> List ) {
    
12. This . pathstring=path;
    
14. This . Listpath=list;
    
16. }
    
18. 
    
20. Public void Run (){
    
22. 
    
24. File file = New File (pathstring) ;
    
26. if (file. isdirectory ()){
    
28. file fs[]=file. Listfiles ();
    
30. if (fs!=null) {
    
32. System . Out. println ("The number of files contained in the directory--->"+fs. length );
    
34. if (fs. length >0){
    
36.                          for ( int i= 0 I<, fs length I+ + ) Span style= "COLOR: #0000CC" >{
    
38.                              if ( fs[ i] isfile ( ) {
    
40.                                  listpath add ( fs[ i] getabsolutepath ( )
    
42.                                   system Out println ( "file---->" + fs[ i getabsolutepath ( )
    
44.                              } else if ( fs< Span style= "COLOR: #0000CC" >[ i] . isdirectory ( ) {
    
46.                                   system Out println ( "directory---->" + fs[ i getabsolutepath ( ) + "/" )
    
47. New Thread(NewGetfilepaththread(Fs[I].GetAbsolutePath()+"/",Listpath)).Start();
    
49. //GetFilePath (Fs[i].getabsolutepath (), listpath);
    
51. 
    
53. }
    
55. }
    
57. }
    
59. }
    
61. }
    
63. }
    
65. }

2. Scan the image files we need , of course, before you define it.
Private List list=new ArrayList ();

2. StringBuffer Buffer = New StringBuffer ();
   
4.                 for ( int I= 0; I<, list . size ( ; I+ + ) Span style= "COLOR: #0000CC" >{
   
6.                      if ( list get ( i endswith ( ". jpg" ) {
   
8. Buffer . Append (list. Get (i) . toString ()+"n");
   
10. }
    
12. }

3, remember to join about SCard card Read and Write permission, this is very important. As for the thread, I won't say much.
Summary: This code in small place tangled for a long time, really should not, the main problem is two, one is how to traverse the folder sub-file, the second, how to get the file path added to;
Hope these can be useful to everyone!
