【问题描述】：
我正在使用 viewpager 片段分页器适配器，它一次加载两个片段如何处理选项菜单一次调用两个片段
public class RTHomeTabFragment extends Fragment implements TabListener,OnBackButtonPressInterfaceForFragment{
public ActionBarActivity parentActivity;
private ActionBar actionBar;
ViewPager mViewPager;
public static int currentPage;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
RTMessagingUtils.log(getClass().getName(), "onCreateView");
View view = inflater.inflate(R.layout.viewpager_tabs, container,false);
parentActivity = (ActionBarActivity) getActivity();
actionBar = parentActivity.getSupportActionBar();
mViewPager = (ViewPager) view.findViewById(R.id.pager);
/* actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);*/
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setCustomView(null);
actionBar.removeAllTabs();
// List<Fragment> fragments = getFragments();
pagerAdapter adapter = new pagerAdapter(getChildFragmentManager(), getFragments());
mViewPager.setAdapter(adapter);
currentPage=mViewPager.getCurrentItem();
Log.d("TestFragments", "currentPage======"+currentPage);
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
currentPage=mViewPager.getCurrentItem();
Fragment fragment=getFragments().get(position);
fragment.setHasOptionsMenu(true);
Log.d("TestFragments", "currentPage======"+currentPage);
}
});
for (int i = 0; i < adapter.getCount(); i++) {
actionBar.addTab(actionBar.newTab().setText(adapter.getPageTitle(i)).setTabListener(this));
}
return view;
}
private List<Fragment> getFragments(){
List<Fragment> fList = new ArrayList<Fragment>();
// add fragments here
fList.add(new Test1());
fList.add(new Test2());
fList.add(new Test3());
return fList;
}
class pagerAdapter extends FragmentPagerAdapter{
private List<Fragment> fragments;
public pagerAdapter(FragmentManager fm, List<Fragment> fragments){
super(fm);
this.fragments = fragments;
}
@Override
public Fragment getItem(int position) {
return this.fragments.get(position);
}
@Override
public int getCount() {
return this.fragments.size();
}
@Override
public CharSequence getPageTitle(int position) {
Locale l = Locale.getDefault();
switch (position) {
case 0:
return getString(R.string.db_jio_chat_chats).toUpperCase(l);
case 1:
return getString(R.string.db_jio_chat_groups).toUpperCase(l);
case 2:

}
return null;
}
}
@Override

片段1
public class Test1 extends Fragment {
private ListView listView;
public ActionBarActivity parentActivity;
ArrayList<String> list = new ArrayList<String>();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.userlist, container, false);
listView = (ListView) view.findViewById(R.id.listView1);
parentActivity = (ActionBarActivity) getActivity();
final ActionBar actionBar = parentActivity.getSupportActionBar();
actionBar.setIcon(R.drawable.ic_launcher);
actionBar.setTitle("UserList");
actionBar.setSubtitle(null);
list.add("Android");
list.add("Android");
list.add("Android");
list.add("Android");
list.add("Android");
list.add("Android");
list.add("Android");
list.add("Android");
list.add("Android");
list.add("Android");
list.add("Android");
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, list);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Test2 test2 = new Test2();
// ((MainActivity) parentActivity).replaceFragment(test2, "chat");
}
});
return view;
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onViewCreated(view, savedInstanceState);
}
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
setHasOptionsMenu(true);
super.onCreate(savedInstanceState);
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// TODO Auto-generated method stub
Log.d("Test1", "******************onCreateOptionsMenu****************");

}
}
片段2
public class Test2 extends Fragment {
public ActionBarActivity parentActivity;
private ListView listView;
ArrayList<String> list = new ArrayList<String>();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
parentActivity = (ActionBarActivity) getActivity();
final ActionBar actionBar = parentActivity.getSupportActionBar();
// actionBar.setIcon(R.drawable.jio_chat_myprofile_add_contact);
actionBar.setTitle("user namednfjgnlxnclkvbnxc");
actionBar.setSubtitle("user status");
View view = inflater.inflate(R.layout.conversation, container, false);
listView = (ListView) view.findViewById(R.id.listView1);
list.add("Android");
list.add("converstion");
list.add("converstion");
list.add("converstion");
list.add("converstion");
list.add("converstion");
list.add("converstion");
list.add("converstion");
list.add("converstion");
list.add("converstion");
list.add("converstion");
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, list);
listView.setAdapter(adapter);
return view;
}
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
setHasOptionsMenu(true);
super.onCreate(savedInstanceState);
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// TODO Auto-generated method stub
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
getActivity().getMenuInflater().inflate(R.menu.new_message_menu, menu);
}
}
【问题讨论】：
-
两个片段需要一个菜单还是两个片段需要单独的菜单？
