文件选择

打开文件选择器

private static final int FILE_SELECT_CODE = 0;

private  void  showFileChooser() {      Intent intent = new  Intent(Intent.ACTION_GET_CONTENT);      intent.setType( "*/*" );      intent.addCategory(Intent.CATEGORY_OPENABLE);        try  {          startActivityForResult( Intent.createChooser(intent, "Select a File to Upload" ), FILE_SELECT_CODE);      } catch  (android.content.ActivityNotFoundException ex) {          Toast.makeText( this , "Please install a File Manager." ,  Toast.LENGTH_SHORT).show();      } }

　　

选择的结果

@Override protected  void  onActivityResult( int  requestCode, int  resultCode, Intent data)  {      switch  (requestCode) {          case  FILE_SELECT_CODE:               if  (resultCode == RESULT_OK) {               // Get the Uri of the selected file              Uri uri = data.getData();              String path = FileUtils.getPath( this , uri);          }                    break ;      } super .onActivityResult(requestCode, resultCode, data); }

　

FileUtils文件

public  class  FileUtils {      public  static  String getPath(Context context, Uri uri) {            if  ( "content" .equalsIgnoreCase(uri.getScheme())) {              String[] projection = { "_data"  };              Cursor cursor = null ;                try  {                  cursor = context.getContentResolver().query(uri, projection, null , null , null );                  int  column_index = cursor.getColumnIndexOrThrow( "_data" );                  if  (cursor.moveToFirst()) {                      return  cursor.getString(column_index);                  }              } catch  (Exception e) {                  // Eat it              }          }            else  if  ( "file" .equalsIgnoreCase(uri.getScheme())) {              return  uri.getPath();          }            return  null ;      } }

　　这个很简单。
