Dateien auflisten Android

[philipp.hofmann]

Das funktioniert jetzt folgendermaßen:

Aufruf Explorer:

Delphi-Quellcode:

     TMessageManager.DefaultManager.Unsubscribe(TMessageResultNotification, HandleActivityMessageTCXWrite);
     TMessageManager.DefaultManager.SubscribeToMessage(TMessageResultNotification, HandleActivityMessageImportRead);
     Intent := TJIntent.Create;
     Intent.setType(StringToJString('*/*'));
     //Intent.setType(StringToJString('application/zip'));//possible but I need gpx-files also
     //Intent.setType(StringToJString('application/gpx'));//not possible
     Intent.setAction(TJIntent.JavaClass.ACTION_GET_CONTENT);
     MainActivity.startActivityForResult(Intent, 0);

Abarbeitung der Auswahl:

Delphi-Quellcode:

   procedure TicTrainerF.HandleActivityMessageGPXRead(const Sender: TObject; const M: TMessage);
   var
     //P: TJavaObjectArray<Jstring>;
     Data:JIntent;
     C: JCursor;
     I: integer;
     uri,filename:String;
     ms: TMemoryStream;
     jis: JInputStream;
     b: TJavaArray<Byte>;
   begin
     if (M is TMessageResultNotification) then
     begin
      mlog.info('start to read GPX-file');
      TMessageManager.DefaultManager.Unsubscribe(TMessageResultNotification, HandleActivityMessageGPXRead);
      data:=TMessageReceivedNotification(M).Value;
      if (data=nil) then
      begin
        mlog.info('nothing to Import');
        exit;
      end;
      uri:=JStringToString(Data.getData.toString);
      //P:=TJavaObjectArray<Jstring>.create(1);
      //P.Items[0]:=StringToJstring('_data');
      mlog.info('try to get GPX-File from: '+uri);
      C := MainActivity.getContentResolver.query(Data.getData, nil {P}, StringToJString(''),nil, StringToJString(''));
      C.moveToFirst;
      for I := 0 to C.getColumnCount - 1 do
      begin
        if JStringToString(C.getColumnName(I)) = '_display_name' then
        begin
         filename:=JStringToString(C.getString(I));
         Break;
        end;
      end;
      mlog.info('try to store GPX-File: '+filename);
      if ((not lowercase(filename).endsWith('.gpx')) and (not lowercase(filename).endsWith('.zip'))) then
      begin
        showInfo(translation.get(3066,'The file')+'|'+filename+'|'+translation.get(3067,'is not a GPX-File.'),TMsgDlgType.mtError);
        exit;
      end;
      ms := TMemoryStream.Create();
      try
        jis := TAndroidHelper.Context.getContentResolver.openInputStream(Data.getData);
        b := TJavaArray<Byte>.Create(jis.available);
        jis.read(b);
        ms.Write(b.Data^, b.Length);
        jis.close;
        mlog.info('prepare save GPX-file to '+filename+' '+IntToStr(b.length));
        TFileUtils.checkDirSequence(TFileUtils.adjustDir(eConfigMyExerciseDirectory.text)+'GPX');
        filename:=TFileUtils.adjustDir(TFileUtils.adjustDir(eConfigMyExerciseDirectory.text)+'GPX')+filename;
        //filename:=StringReplace(filename,' ','',[rfReplaceAll]); //bad to search for the video
        mlog.info('save GPX-file to '+filename+' '+IntToStr(b.length));
        ms.saveToFile(filename);
        mlog.info('saved GPX-file');
      finally
        ms.free();
      end;
      mlog.info('read GPX-file '+filename);
      readExerciseFromGPX(btWizardGPXRead,filename,true,true);
     end;
   end;

Mehrfachauswahl muss ich mir auch noch anschauen.
