在一个布局内重复使用包含多个布局的相同布局 - TabLayout + ViewPager + RecyclerView(在一个视图中的多个视图)

问题描述:

我正在使用Galaxy Tab E SM-T560。我是一名3年的android开发人员,只是在网络搜索问题解决方面工作。我搜索了像通货膨胀和getParent()视图实现的东西,他们都没有工作。在一个布局内重复使用包含多个布局的相同布局 - TabLayout + ViewPager + RecyclerView(在一个视图中的多个视图)

在我来说,我对平板电脑的布局,有2包括具有TabLayout加ViewPager布局,并与该viewpager我recyclerview使用

我的代码是不是在某些时候工作,我已经做了一些复制粘贴,知道为什么不工作,但没有进行长时间的搜索。

下面是这里面

这里只有一个工作视角的图像,是做所有的这种神奇的抽屉右侧的片段代码:

public class HorarioFragment extends Fragment { 

private boolean isToBlumenau; 
private View rootView; 

public static HorarioFragment newInstance(boolean isToBlumenau) { 
    Bundle bundle = new Bundle(); 
    HorarioFragment fragment = new HorarioFragment(); 
    fragment.isToBlumenau = isToBlumenau; 
    bundle.putString(fragment.getTag(), AppUtils.getFragmentKey(fragment)); 
    fragment.setArguments(bundle); 
    return fragment; 
} 

public HorarioFragment() { 
    super(); 
} 

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    if (rootView == null) { 
     if (!AppUtils.isTablet()) { 
      rootView = inflater.inflate(R.layout.fragment_viewpager_tablayout_horario, container, false); 
      ViewPager viewPager = (ViewPager) rootView.findViewById(R.id.viewpager); 
      TextView tvDestino = (TextView) rootView.findViewById(R.id.tvDestino); 
      ImageView imgInfo = (ImageView) rootView.findViewById(R.id.imgInfo); 
      if (isToBlumenau) { 
       viewPager.setAdapter(new HorarioPomerodeBlumenauFragmentStatePageAdapter(getFragmentManager(), getContext())); 
       tvDestino.setText(getResources().getStringArray(R.array.rota_horario)[0]); 
      } else { 
       viewPager.setAdapter(new HorarioBlumenauPomerodeFragmentStatePageAdapter(getFragmentManager(), getContext())); 
       tvDestino.setText(getResources().getStringArray(R.array.rota_horario)[1]); 
      } 

      TabLayout tabLayout = (TabLayout) rootView.findViewById(R.id.tabs); 
      tabLayout.setupWithViewPager(viewPager); 
      AppUtils.tabLayoutRuleTablet(tabLayout); 

      tvDestino.setOnClickListener(switchHorario()); 
      imgInfo.setOnClickListener(infoHorario()); 
     } else { 
      rootView = inflater.inflate(R.layout.horario_tablet, container, false); 

      rootView.post(new Runnable() { 
       @Override 
       public void run() { 
        setUpPomerodeBlumenau(); 
        setUpBlumenauPomerode(); 
       } 
      }); 
     } 
    } 
    return rootView; 
} 

private void setUpPomerodeBlumenau() { 
    View view = rootView.findViewById(R.id.layout_horario_pombnu); 

    ViewPager viewPager = (ViewPager) view.findViewById(R.id.viewpager); 
    viewPager.setAdapter(
      new HorarioPomerodeBlumenauFragmentStatePageAdapter(
        getChildFragmentManager(), 
        getContext())); 

    TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tabs); 
    tabLayout.setupWithViewPager(viewPager); 
} 

private void setUpBlumenauPomerode() { 
    View view = rootView.findViewById(R.id.layout_horario_bnupom); 

    ViewPager viewPager = (ViewPager) view.findViewById(R.id.viewpager); 
    viewPager.setAdapter(
      new HorarioBlumenauPomerodeFragmentStatePageAdapter(

        getContext())); 

    TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tabs); 
    tabLayout.setupWithViewPager(viewPager); 
} 

这是我的布局horario_tablet.xml

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

    <LinearLayout 
     android:id="@+id/layout_horario_pombnu" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_weight="1" 
     android:orientation="vertical"> 

     <TextView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:background="@color/colorAccent" 
      android:gravity="center" 
      android:paddingBottom="4dp" 
      android:paddingTop="10dp" 
      android:text="@string/pomerodeblumenau" 
      android:textAppearance="?android:attr/textAppearanceMedium" 
      android:textColor="@android:color/white" /> 

     <include layout="@layout/fragment_viewpager_tablayout" /> 

    </LinearLayout> 

    <TextView 
     android:layout_width="2dp" 
     android:layout_height="match_parent" 
     android:background="#FFF" /> 

    <LinearLayout 
     android:id="@+id/layout_horario_bnupom" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_weight="1" 
     android:orientation="vertical"> 

     <TextView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:background="@color/colorAccent" 
      android:gravity="center" 
      android:paddingBottom="4dp" 
      android:paddingTop="10dp" 
      android:text="@string/blumenaupomerode" 
      android:textAppearance="?android:attr/textAppearanceMedium" 
      android:textColor="@android:color/white" /> 

     <include layout="@layout/fragment_viewpager_tablayout" /> 
    </LinearLayout> 

</LinearLayout> 

这将fragment_viewpager_tablayout.xml

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <android.support.design.widget.AppBarLayout 
     android:id="@+id/appbar" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:theme="@style/AppTheme.AppBarOverlay" 
     app:elevation="0dp"> 

     <android.support.design.widget.TabLayout 
      android:id="@+id/tabs" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:background="@color/colorPrimaryDark" 
      app:tabBackground="@color/colorPrimaryDark" 
      app:tabGravity="center" 
      app:tabIndicatorColor="@android:color/white" 
      app:tabMode="scrollable" 
      app:tabSelectedTextColor="@android:color/white" 
      app:tabTextColor="@color/colorPrimary" /> 
    </android.support.design.widget.AppBarLayout> 

    <android.support.v4.view.ViewPager 
     android:id="@+id/viewpager" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_below="@+id/appbar" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" /> 
</android.support.design.widget.CoordinatorLayout> 

RecyclerView工作正常,为手机所有的意见都很好,只是在这种情况下,horario_tablet.xml内的第二布局的显示选项卡,但不会显示第二个布局(@ + id/layout_horario_bnupom)的tablayout上的每个选项卡的片段,即使代码相同。

发现我已经取代所有的硬编码XML列入标签之前horario_tablet.xml

OK了anwear ,但你为什么要这样?

很简单:出于某种原因,Android Framework使用viewpager的第一个实例(布局上的第一个viewpager),而不是重新创建另一个。

SO ??????

因此,解决办法是给特定ID对每个viewpager/tablayout

:)

编辑: OK,但你怎么得出那个结论的? (框架,例如,唧唧歪歪?)
