android - Where have I to define the onclick for button in customized dialog? -


I have found a dialog in a dialog. It works fine.

I use a custom layout for my dialogue. These are two buttons

release_scan_dialog.xml 

   & Lt; Button Android: id = "@ + id / storage" Android: layout_width = "match_parent" Android: layout_height = "wrap_content" Android: text = "scan2" /> & Lt; / LinearLayout & gt;   
  ScanFragment.java   
  public class ScanFragment extends DialogFragment {public Android. app.Dialog onCreateDialog (android.os.Bundle savedInstanceState) {AlertDialog dialog = new AlertDialog.Builder (this.getActivity ()) .setView (this.getActivity (). getLayoutInflater (). add (R.layout.release_scan_dialog, null) ) .setTitle (R.string.title_store) .setPositiveButton (android.R.string.ok, new DialogInterface.OnClickListener () {@Override public void onClick (DialogInterface dialog, int which) {}}) .setNegativeButton (android.R .string.cancel, New DialogInterface.OnClickListener () {@Override Click on Public Zero (DialogInterface dialog, int which) {}} .create (); dialog.setOnShowListener (New DialogInterface.OnShowListener () {@Override public void onShow (DialogInterface dialog) {((AlertDialog) dialog) .getButton (AlertDialog.BUTTON_POSITIVE) .setEnabled (false);}}); // This is a NullPointerException dialog.findViewById (R.id.code) .setOnClickListener (New OnClickListener () {@Override see public void onClick () {((AlertDialog) getDialog ()). GetButton (will crush with AlertDialog.BUTTON_POSITIVE) .setEnabled (true);}}); Return dialog; }}   
 If I try to define  onClick  for both buttons then  is NullPointerException . Thanks to any response to  onClick   
 which is the correct event.   
 
 release_scan_dialog  within the inflated view with layout = "text"> 
  code  Button can be found.  
  public class ScanFragment DialogFragment extended {public android.app.Dialog onCreateDialog (android.os.Bundle savedInstanceState) inflates scene {// release_scan_dialog layout. Final View release_scan_view = getActivity () GetLayoutInflater (). Fulao (R. Late .rele_scan_dialog, blank); AlertDialog dialog = new AlertDialog.Builder (this.getActivity ()) .setView (release_scan_view) .setTitle (R.string.title_store) .setPositiveButton (android.R.string.ok, New DialogInterface.OnClickListener () {@Override public void onClick (DialogInterface dialog, int which) {}}) .setNegativeButton (android.R.string.cancel, new DialogInterface.OnClickListener () {@Override public void onClick (DialogInterface dialog, int which) {}}) .create () ; dialog.setOnShowListener (New DialogInterface.OnShowListener () {@Override public void onShow (DialogInterface dialog) {((AlertDialog) dialog) .getButton (AlertDialog.BUTTON_POSITIVE) .setEnabled (false);}}); // Release_scan_dialog Set OnClickListener for the 'Code' button in the layout. release_scan_view.findViewById (R.id.code) .setOnClickListener (New OnClickListener () {@Override see public void onClick () {((AlertDialog) getDialog ()) getButton (AlertDialog.BUTTON_POSITIVE) .setEnabled (right) ;.}} ); Return dialog; }}

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.

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...
