Question

我是android的初学者我想制作标签我拿了样本并对其进行了编辑，为每个标签制作了一个布局但我无法找到将每个标签的每个布局按钮的听众放在代码中的位置！

public class Game extends FragmentActivity implements ActionBar.TabListener {

    static int Tab_no ;



    private static final String STATE_SELECTED_NAVIGATION_ITEM = "selected_navigation_item";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.game);


        // Set up the action bar.
        final ActionBar actionBar = getActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        // For each of the sections in the app, add a tab to the action bar.
        actionBar.addTab(actionBar.newTab().setTag("round").setText("Round").setTabListener(this));
        actionBar.addTab(actionBar.newTab().setTag("score").setText("Score").setTabListener(this));
     }

    @Override
    public void onRestoreInstanceState(Bundle savedInstanceState) { // 3ashan law rege3na men ay makan yrg3ny le mkany
        if (savedInstanceState.containsKey(STATE_SELECTED_NAVIGATION_ITEM)) {
            getActionBar().setSelectedNavigationItem(
                    savedInstanceState.getInt(STATE_SELECTED_NAVIGATION_ITEM));
        }
    }

   @Override
    public void onSaveInstanceState(Bundle outState) {  // 3ashan law killed yrg3ny tany le makany
        outState.putInt(STATE_SELECTED_NAVIGATION_ITEM,
                getActionBar().getSelectedNavigationIndex());
    }



    public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
    }

    public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
        // When the given tab is selected, show the tab contents in the container
         Fragment fragment = new SectionFragment();
         Tab_no =  tab.getPosition() + 1 ;
         getSupportFragmentManager().beginTransaction()
                 .replace(R.id.container, fragment)
                 .commit();

    }

    public void onTabReselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
    }

    /**
     * A dummy fragment representing a section of the app, but that simply displays dummy text.
     */
    public static class SectionFragment extends Fragment {
        public SectionFragment() {
        }




        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {




            if (Tab_no==1)
            {


            return inflater.inflate(R.layout.round , container, false);


            }

            else {

            return inflater.inflate(R.layout.score , container, false);
            }


        }



    }


}

您可以在onCreateView()

内撰写

public class fragmentname extends Fragment{
Activity referenceActivity;
View parentHolder;

Button backBtn;

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    referenceActivity = getActivity();
    parentHolder = inflater.inflate(R.layout.yourlayout, container,
            false);

    backBtn = (Button) parentHolder.findViewById(R.id.back_btn);

    backBtn.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {

        }
    });
    return parentHolder;
}
}

我在哪里可以用片段编写java代码？
