我用下面的代码创建了一个 FragmentActivity

public class Activity_principal1 extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_principal1);

        List<Fragment> fragments = getFragments();
        AcoesMuscularesAdapter ama = new AcoesMuscularesAdapter(getSupportFragmentManager(), fragments);
        ViewPager vp_contentAcoesMusculares_SequenciaExercicios = (ViewPager) findViewById(R.id.vp_contentAcoesMusculares_SequenciaExercicios);
        vp_contentAcoesMusculares_SequenciaExercicios.setAdapter(ama);

    }

    private List<Fragment> getFragments(){
        List<Fragment> fList = new ArrayList<Fragment>();
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 1",1));
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 2",2));
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 3",3));
        return fList;
    }

}

这是我的 XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/framelayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white" >

<android.support.v4.view.ViewPager
    android:id="@+id/vp_contentAcoesMusculares_SequenciaExercicios"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    android:layout_marginTop="5dp"
    android:background="#fff" />

</RelativeLayout>

FragmentAcoesMusculares（getFragments()方法内的代码）就是下面这个类

public class FragmentAcoesMusculares extends Fragment{

    public static final String EXTRA_MESSAGE = "EXTRA_MESSAGE";

    public static final FragmentAcoesMusculares newInstance(String message,int item)
    {
        FragmentAcoesMusculares f = new FragmentAcoesMusculares();
        Bundle bdl = new Bundle(item);
        f.item = item;
        bdl.putString(EXTRA_MESSAGE, message);
        f.setArguments(bdl);
        return f;
    }


    private int item;
    private ImageView images;
    private String urlString = "";
    int i = 0;;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
         final View v = inflater.inflate(R.layout.linha_acoesmusculares_viewpager, container, false);

         images = (ImageView) v.findViewById(R.id.images);
         final Runnable r = new Runnable() {

            @Override
            public void run() {
            if(i == 0){
                urlString = "http://54.232.207.226/atlas.limittraining.com.br/thumb/grupo-muscular-sequencia/1/0/0/bb91e662b4fd6ffde74757ff9bd6e108.jpg";
            }else{
                urlString = "http://54.232.207.226/atlas.limittraining.com.br/thumb/grupo-muscular-sequencia/1/0/0/7730258ca72a75365d0c4b92a1a68a0a.jpg";
            }

            AQuery aquery = new AQuery(images);
            aquery.image(urlString);
            i++;
            if(i >= 2){
                i = 0;
            }
            images.postDelayed(this, 1500);
        }
    };
    images.postDelayed(r, 1500);

    return v;
}

}

这是我的适配器

public class AcoesMuscularesAdapter extends FragmentPagerAdapter{

    private List<Fragment> fragments;

    public AcoesMuscularesAdapter(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();
    }
}

上面的所有代码都运行良好。

现在我正在尝试创建一个拥有我的 ViewPager 的 PopupWindow（或 DialogFragment）。

我为此修改了我的代码（现在我的 XML activity_principal1 只有一个按钮，新的 XML 弹出窗口有我的 ViewPager）

public class Activity_principal1 extends FragmentActivity {

private LayoutInflater inflater;
private View view;
private PopupWindow window;
private Button abrir;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_principal1);

    List<Fragment> fragments = getFragments();
    AcoesMuscularesAdapter ama = new AcoesMuscularesAdapter(getSupportFragmentManager(), fragments);

    inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    view = inflater.inflate(R.layout.popup, null,true);

    ViewPager vp_contentAcoesMusculares_SequenciaExercicios = (ViewPager) view.findViewById(R.id.vp_contentAcoesMusculares_SequenciaExercicios);
    vp_contentAcoesMusculares_SequenciaExercicios.setAdapter(ama);

    window = new PopupWindow(view);

    abrir = (Button) findViewById(R.id.abrir);
    abrir.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            window.showAsDropDown(v);
        }
    });
}

private List<Fragment> getFragments(){
    List<Fragment> fList = new ArrayList<Fragment>();
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 1",1));
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 2",2));
        fList.add(FragmentAcoesMusculares.newInstance("Fragment 3",3));
    return fList;
}

}

最后，这是现在发生的错误。

有人知道我做错了什么吗？

我找到了解决问题的方法。

开始了

首先，我使用 DialogFragment 而不是 PopupView。

所以在我的主要活动中，我只创建了一个调用我的 DialogFragment 的 Button。

public class Activity_principal1 extends FragmentActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_principal1);

        Button abrir = (Button) findViewById(R.id.botao);
        abrir.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                new DialogFragmentWindow().show(getSupportFragmentManager(), "");
            }
        });
    }

}

我的适配器仍然与问题相同。

这就是魔法发生的地方。

public class DialogFragmentWindow extends DialogFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.popup, container);

        ViewPager vp_contentAcoesMusculares_SequenciaExercicios = (ViewPager) view.findViewById(R.id.vp_contentAcoesMusculares_SequenciaExercicios);
        List fragments = getFragments();
        AcoesMuscularesAdapter ama = new AcoesMuscularesAdapter(getChildFragmentManager(), fragments);
        vp_contentAcoesMusculares_SequenciaExercicios.setAdapter(ama);

        getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);

        return view;
    }

    private List getFragments(){
        List fList = new ArrayList();
            fList.add(FragmentAcoesMusculares.newInstance("Fragment 1",1));
            fList.add(FragmentAcoesMusculares.newInstance("Fragment 2",2));
            fList.add(FragmentAcoesMusculares.newInstance("Fragment 3",3));
        return fList;
    }
}

不同之处在于 getChildFragmentManager()。这段小代码拯救了我的一天。

对此的解释是，当我使用 getSupportFragmentManager() 时，甚至指示视图寻呼机位于另一个布局 XML 中，他认为它位于主布局 XML 中。

现在我的应用程序获取了子片段，所以现在他看到了 ViewPager。

就是这样。

谢谢大家。

我遇到了同样的问题，我尝试在我的对话框中使用另一个 xml 模板创建另一个 viewpager，你知道我没有找到解决这个问题的信息，但是我使用了另一个 view pager 实现，它与 supporta 库中的 viewpager 完全相同，是叫 JazzyViewPager，有多个动画真可爱！我建议你使用，这个。
