java - 如何在ArrayAdapter类的getView方法中使用startActivityForResult？

我想使用startActivityForResult从ArrayAdapter类中调用另一个意图，但是我做不到。这是我的代码。

ArrayAdapter类构造函数

public QsShareManagerAdapter(Context context, String[] values, Long[] size,String[] time,
        boolean isRoot, Boolean[] attrdir, ArrayList<Boolean> selected,boolean type,
        LinearLayout linearLayout,String SHARE,String qsUsername)
{
    super(context, R.layout.listlayout, values);
    this.context = context;
    this.values = values;
    this.size = size;
    this.time=time;
    this.isRoot = isRoot;
    this.attrdir = attrdir;
    this.selected = selected;
    this.type=type;
    this.linearLayout=linearLayout;
    this.SHARE=SHARE;
    this.qsUsername=qsUsername;
}





    @Override
public View getView(final int position, View convertView, ViewGroup parent)
{
    String spliter = "/";
    tag=SHARE.split(spliter);

    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(R.layout.listlayout, parent, false);

    //
    addFiles=(Button)linearLayout.findViewById(R.id.add_files);
    manageUser=(Button)linearLayout.findViewById(R.id.manage_users);
    deleteSharedFolder=(Button)linearLayout.findViewById(R.id.delete_shared_folder);
    copyFiles=(Button)linearLayout.findViewById(R.id.copy);
    deleteFiles=(Button)linearLayout.findViewById(R.id.delete_files);

    addFiles.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
              Intent intent=new Intent(context,QsFileSelector.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  ;
              intent.putExtra(QsFileSelector.SELECTED_FILES,existing_seletedFile);
              intent.putExtra(QsFileSelector.FILE_OR_DIRECTORY, tag[6]);
              startActivityForResult(intent);
            Toast.makeText(context, "Add Files", Toast.LENGTH_SHORT).show();
        }
    });

    manageUser.setOnClickListener(new OnClickListener() {

            Toast.makeText(context, "Manage User", Toast.LENGTH_SHORT).show();
        }
    });

    deleteSharedFolder.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
              boolean status=serverURL.folderRequestResponseURI("DELETED_CREATOR", tag[6], qsUsername, tag[5], null, "");
              if(status){
                  Toast.makeText(context, "Delete Share Folder", Toast.LENGTH_SHORT).show();
              }
        }
    });

    copyFiles.setOnClickListener(new OnClickListener() {

        @Override

        }

        else if (sizeinKb > 1048576) {
            double sizeinGB = sizeinKb / (1024 * 1024);
            sizeView.setText(Double.toString(round(sizeinGB, 2,

        }

        else {

最佳答案

addFiles.setFocusable(false);

我认为您应该将Context更改为Activity ...在您的Adapter构造函数中将其更改...
activity.startActivityForResult(intent，position);
