我想使用startActivityForResult從ArrayAdapter類調用另一個意圖，但我不能這樣做。這裏是我的代碼。如何在ArrayAdapter類的getView方法中使用startActivityForResult？
一個ArrayAdapter類構造函數
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() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "Manage User", Toast.LENGTH_SHORT).show();
}
});
deleteSharedFolder.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {

boolean status=serverURL.folderRequestResponseURI("DELETED_CREATOR", tag[6], qsUsername, tag[5], null, "");

它不工作。我已經這樣做了。 –
爲什麼？有什麼錯誤？請參閱我的更新回答 –
對於類型Context，未定義方法startActivityForResult（Intent，int）。這是你更新後的錯誤。 –
