android - DialogFragment with WebView - Handling back button? -


It should be that simple, but I can not find a working solution ...

I have a DialogFragment that has a linear layout that includes a WebView. When the user navigates into the webview, I want to be able to go back using the back button. When he / she reaches the start page (i.e. can not go back), the back button dialog should be closed. I tried setCancelable (wrong) and DialogFragments was reversed with an OnKeyListener on the root view (one that was incremented), but it never seems to call back the button. I do not want to include onBackPressed of the activity (it should be controlled by DialogFragment if possible).

So far the solution I found is to install WebView's OnKeyListener like this: 

  @Override Public View onCreateView (LayoutInflater Inflator, ViewGroup Container, Bundle savedInstanceState) {View V = inflater.inflate (R.layout.dialog_fragment_layout, Container, Incorrect) WebView = (WebView) V. FindViewById (R.id.webView) ); WebView.setOnKeyListener; return v;} OnKeyListener keyListener = new OnKeyListener () {@Override Public Boolean onKey (see V, Integer Keycode, KeyEve NT Event) {if (keycode == KeyEvent.KEYCODE_BACK & amp; ; Event.getAction () == KeyEvent.ACTION_DOWN) {if (webView.canGoBack ()) {webView.goBack (); Back true; } } return false; }};

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. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

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...
