Android 如何在操作栏中从微调器启动片段？

我有一个带滑动抽屉的应用程序，15个片段（滑动）标签，带有编号为1-15的查看页面，操作栏中的微调器，显示15个片段的查看页面 我需要的是，当我在微调器下拉列表中选择选项4（例如）时，我希望屏幕显示片段4以及4的视图寻呼机 我怎么能做到呢

当用户选择微调器项目时，必须执行以下步骤：

首先通过调用

   TabbedActivity  f  =  (TabbedActivity) getSupportFragmentManager().findFragmentById(TabbedActivity.Tag);

然后您必须在该片段中获得

viewpager

，您可以使用

getter

-

setter

或声明它

public

，我假设

getter

方法：

   f.getViewPager().setCurrentItem(the position you want to go, false);

因此，您的代码必须类似于：

请注意，您有两个

选项卡Activity

，我不知道显示的是哪一个，因此您必须在下面的代码中选择正确的一个：

@Override
public boolean onNavigationItemSelected(int position, long arg1) {

       TabbedActivity  f  =  (TabbedActivity) getSupportFragmentManager().findFragmentById(TabbedActivity.Tag);
      f.getViewPager().setCurrentItem(position, false);
      return true;

 }

---

首先，您没有

viewpager

！！微调器工作，我获得了电影4的选项卡（如果从微调器中选择了电影4），但我丢失了viewpager条..我希望它以某种方式工作：（

viewpager strip

你是什么意思？我想我们没有常用的单词定义，你的词汇表有问题。viewpager是一个小部件，可以通过滑动来显示片段，因此此代码进入微调器的切换框…如果类型对象的方法setCurrentItem未定义，请尝试一下。你犯了一些错误这里因为是的，我在MainActivity.java中添加了它……我认为它应该放在TabbedActivity.java中，不是吗？：-（不明白你的意思！）！！

@Override
public boolean onNavigationItemSelected(int position, long arg1) {

       TabbedActivity  f  =  (TabbedActivity) getSupportFragmentManager().findFragmentById(TabbedActivity.Tag);
      f.getViewPager().setCurrentItem(position, false);
      return true;

 }
