android - Increment TextView with button click -


Thanks for the help, but I am still struggling. I did this:

Button in XML: 

  & amp; Android: layout_centerHorizontal = "true" android: layout_marginTop = "43dp" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Background = "@ Android: Color / White" Android: onClick = "incrementScore" Android: text = "@ string / player" />   
  Main code (in the end):   
  Where do I get this code especially when I press the app crash button should keep?   
  context reference; TextView TV; Button incremental; Public zero growth score (bundle saved instenstate) {super.onCreate (SavedInstanceState); SetContentView (R.layout.fragment_home); TV = (TextView) FindViewById (R.id.textView1); Incrementer = (button) findViewById (R.id.button1); Context = this; . Incrementer.setOnClickListener (New View.OnClickListener) {@Override Public Zero onClick (see v) {string present_value_string = tv.getText () toString (); Integer present_value_int = Integer.parseInt (present_value_string); present_value_int ++; tv.setText (String.valueOf (present_value_int));}}); }    
 
 
 Build in your class:  
  int Score = 0;   
 And then;  
  button.setOnClickListener (New OnClickListener () {@Override Public Zero onClick (see v) {// Scores like score operation operation = = increment_value; t1.setText ("" + score); }});   
 If you need to "save" scores, then you have left the application, you need to share to show / update the stock.

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...
