android - Dialog and displaying it in a TextView -


IÂ've had a dialog where I can select many things, in my example content for a pizza. I want to select / select more than one item but every time I run the app, I can select more than one but it only displays one. Here's my code, I was ignoring it once but my mistake could not be found. I hope you can help me. Thanks in advance;) 

  Private Zero pizzaBelagDialog () {// Variablen Ultimate ArrayList & LT; Integer & gt; Arraybill = new arreelist & lt; Integer & gt; (); DialogBuilder = New AlertDialog.Builder (this); Last string [] strBelaege = {"Hühnchen", "Pepperoni", "Pilze", "Zwiebeln", "Speak", "Oliven", "Ananas", "Pommes", "SOA ?? e", "Meeresfrüchte"} ; // process strBelag = "\ n Belag: \ n"; DialogBuilder.setTitle ("WAhle deinen Belag aus"); dialogBuilder.setMultiChoiceItems (strBelaege, null, New DialogInterface.OnMultiChoiceClickListener () {@Override public void onClick (DialogInterface dialogue that integer, boolean isChecked) {if (isChecked) {arrayBelag.add (a);} else if (arrayBelag.contains (Joe)) {arrayBelag.remove (Integer.valueOf (Joe));}}}); DialogBuilderksetPositiveButton ( "OK", the new DialogInterface.OnClickListener () {@Override public void onClick (DialogInterface dialog, int which) {(int intLoop = 0 in; intLoop & LT; arrayBelag.size (for); intLoop ++ ) {strBelag = strBelaege [(int) arrayBelag .Get (intLoop)] ""; display () ;;} Toast.makeText .show () (getApplicationContext () ,, Toast.LENGTH_SHORT ". Belag ausgewählt wurde") }}); dialogBuilder.setNegativeButton ( "Cancel", new DialogInterface.OnClickListener () {@Override public void onClick (DialogInterface dialog, int which) {Toast.makeText (getApplicationContext (), "Belag nicht ausgewählt wurde.", Toast.LENGTH_SHORT ). Show ();}}); // Output AlertDialog Dialogue PizzaBelag = dialogBuilder.create (); DialogPizzaBelag.show (); } Text   
 Syntac   
 
 
 In each loop you override your variable strBelag . You should use this:.  strBelag + = Your code + ""  This way you keep the value added to the previous loop and do not change it   <. / html>

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
