Question

我对android和facebook插件很新。按照facebook中提到的步骤进行操作开发者网站。 https://developers.facebook.com/docs/android/scrumptious/authenticate/
转到第3步。

   I followed it without missing any steps. 
   However, I do not see a menu at the bottom when i am logged in.Any help?

  Below is the snippet of important codes and xml.
@Override
    public boolean onPrepareOptionsMenu(Menu menu) {
        // only add the menu when the selection fragment is showing
        if (fragments[SELECTION].isVisible()) {
            if (menu.size() == 0) {
                Log.d("onPrepareOptionsMenu","Yes");

                settings = menu.add(R.string.settings);
            }
            return true;
        } else {
            menu.clear();
            settings = null;
        }
        return false;
    }

遵循main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <fragment android:name="com.punit.xxx.SelectionFragment"
          android:id="@+id/selectionFragment"
          android:layout_width="match_parent"
          android:layout_height="match_parent" />
    <fragment android:name="com.punit.xxx.SplashFragment"
          android:id="@+id/splashFragment"
          android:layout_width="match_parent"
          android:layout_height="match_parent" />
    <fragment android:name="com.facebook.widget.UserSettingsFragment"
          android:id="@+id/userSettingsFragment"
          android:layout_width="match_parent"
          android:layout_height="match_parent" />
</LinearLayout>

我试着写一些日志，发现OnPrepareotionsMenu从未被调用过。

Answer 1

从代码中删除onPrepareOptionsMenu（菜单菜单）。

添加

  *item
    android:id="@+id/action_logout"
    MyNews:showAsAction="never"
    android:actionProviderClass="android.support.v7.widget.ShareActionProvider"
    android:orderInCategory="10"
    android:title="@string/logout"/*

注意：将*替换为＆lt;或＆gt;。

添加

@Override
public boolean onOptionsItemSelected(MenuItem item) {

switch(item.getItemId()){
case R.id.action_logout:
    showSettingsFragment();
    return true;
}
return false;


}
public void showSettingsFragment(){
    showFragment(SETTINGS, true);
}

它对我有用。
