ViewPager与PopupWindow（或DialogFragment）中的Fragments - 错误：找不到用于片段的视图
ViewPager与PopupWindow（或DialogFragment）中的Fragments - 错误：找不到用于片段的视图
我使用以下代码创建了一个FragmentActivity：
public class Activity_principal1 extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_principal1);
List 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 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;
}
}
这是我的XML：
FragmentAcoesMusculares（在getFragments（）方法中的代码）是以下类：
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Adapter：
public class AcoesMuscularesAdapter extends FragmentPagerAdapter{
private List fragments;
public AcoesMuscularesAdapter(FragmentManager fm, List 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();
}
}
以上所有代码都可以正常工作。
现在我正在尝试创建一个PopupWindow（或DialogFragment），其中包含我的ViewPager。
我修改了代码（现在我的XML activity_principal1只有一个按钮，新的XML弹出窗口中包含我的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 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 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;
}
}
最后，这是现在出现的错误：

有谁知道我在做什么错了吗？
谢谢和问候。
