Oke guyz,

i made a xml parser thanks to this forum, but i have a new problem.



it makes 3 spinners and after that it reads the values out of it and prints the right text. it all happens when the app starts up. but now i want to add a button and when you press the button this all happens. so i tried to make a class into my code and the class holds the xml parser and other stuf. In the public void oncreate i want to make the button code that calls the xml class. but when i make this my Strings wont work any more and i have to add final, but final means that you can't edit the String. so how can i get this working?



this is my code:

I'm not sure if I understand your question 100%, but what I would do is create a completely seperate class which extends activity, and in that class, you have your button declaration.

Maybe a concrete example will help. Say you have a java class menu, and a java class action. The menu has the button that will start action. So what you do is you have to have a different xml for each.

Code: Select all

public class MainMenu extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
   
    Button actionButton = (Button)findViewById(R.id.button1);
        actionButton.setOnClickListener(new OnClickListener() {
           public void onClick(View v) {
              startActivity(new Intent("<packagename>.ACTION")); // replace package name with your package name
           }
        });


then in the action class yuo have everything you already have.

(in main.xml)
in the xml for main, you have your button named button1 -

Code: Select all

    <Button
         android:id = "@+id/button1"
         android:layout_height = "wrap_content"
         android:layout_width = "wrap_content"
         android:background = "@drawable/directory_button"
         />    

and then make sure you declare the intent in the manifest by creating a new activity

Code: Select all

        <activity android:name=".Action" //replace this with .<name of your java class>
                  android:label="@string/app_name"
                  android:theme="@android:style/Theme.NoTitleBar">>
            <intent-filter>
                <action android:name= "<packagename>.ACTION" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

hope that helps somewhat!
