El contenido de la ficha permanece visible después de cambiar la pestaña después del cambio de orientación

Estoy utilizando ActionBarSherlock para implementar un ActionBar con pestañas en mi aplicación. Cuando inicio la aplicación y cambie de pestaña a pestaña, todo está bien. Sin embargo, cuando cambio de modo vertical a modo horizontal, el contenido de la ficha que fue la última vez activo permanece visible. Cambiar a otra ficha da como resultado el dibujo del nuevo contenido encima del contenido antiguo (ver imagen).

• Android manifest.xml
• EditText no recibe eventos clave TAB - stock soft vk
• Android multiple videoView problem, Galaxy Tab específico
• Fragmento se inicializa dos veces al recargar la actividad con pestañas cuando cambia la orientación
• Pestañas android - iniciar una nueva actividad

Mi clase principal:

 public class TreinVerkeer extends SherlockFragmentActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setupTabs(savedInstanceState); } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getSupportMenuInflater(); inflater.inflate(R.menu.menu, menu); return true; } private void setupTabs(Bundle savedInstanceState) { ActionBar actionBar = getSupportActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); Tab tab = actionBar.newTab().setText("STATIONS").setTabListener(new TabListener<StationsFragment>(this, "stations", StationsFragment.class)); actionBar.addTab(tab); tab = actionBar.newTab().setText("ROUTE").setTabListener(new TabListener<RouteFragment>(this, "route", RouteFragment.class)); actionBar.addTab(tab); tab = actionBar.newTab().setText("DELAYS").setTabListener(new TabListener<DelaysFragment>(this, "delays", DelaysFragment.class)); actionBar.addTab(tab); if (savedInstanceState != null) { actionBar.setSelectedNavigationItem(savedInstanceState.getInt("tab", 0)); } } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putInt("tab", getSupportActionBar().getSelectedNavigationIndex()); } } 

TabListener (desde "Agregar pestañas de navegación" en el sitio de desarrolladores de Android con algunos cambios menores):

 public class TabListener<T extends SherlockFragment> implements com.actionbarsherlock.app.ActionBar.TabListener { private SherlockFragment mFragment; private final Activity mActivity; private final String mTag; private final Class<T> mClass; /** * Constructor used each time a new tab is created. * * @param activity * The host Activity, used to instantiate the fragment * @param tag * The identifier tag for the fragment * @param clz * The fragment's Class, used to instantiate the fragment */ public TabListener(Activity activity, String tag, Class<T> clz) { mActivity = activity; mTag = tag; mClass = clz; } /* The following are each of the ActionBar.TabListener callbacks */ public void onTabSelected(Tab tab, FragmentTransaction ft) { // Check if the fragment is already initialized if (mFragment == null) { // If not, instantiate and add it to the activity mFragment = (SherlockFragment) SherlockFragment.instantiate(mActivity, mClass.getName()); ft.add(android.R.id.content, mFragment, mTag); } else { // If it exists, simply attach it in order to show it ft.attach(mFragment); } } public void onTabUnselected(Tab tab, FragmentTransaction ft) { if (mFragment != null) { // Detach the fragment, because another one is being attached ft.detach(mFragment); } } public void onTabReselected(Tab tab, FragmentTransaction ft) { // User selected the already selected tab. Usually do nothing. } } 

Y StationsFragment ( RouteFragment y DelaysFragment son iguales, con solo texto diferente)

 public class StationsFragment extends SherlockFragment { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.stationsfragment, container, false); } } 

Con eso el archivo de diseño para StationsFragment :

 <?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="vertical" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Stations" /> </LinearLayout> 

Y finalmente el archivo Manifest:

 <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.myapp" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".TreinVerkeer" android:label="@string/app_name" android:theme="@style/Theme.Sherlock.Light" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> 

Tuve el mismo problema antes de iniciar la aplicación (sin cambiar la orientación), esto se resolvió mediante la eliminación de setContentView(R.layout.main) en el onCreate de la clase principal. No puedo encontrar una solución para esto sin embargo. Puede alguien ayudarme con esto?

 public void onTabSelected(Tab tab, FragmentTransaction ft) { SherlockFragment preInitializedFragment = (SherlockFragment) mActivity.getSupportFragmentManager().findFragmentByTag(mTag); // Check if the fragment is already initialized if (mFragment == null && preInitializedFragment == null) { // If not, instantiate and add it to the activity mFragment = (SherlockFragment) SherlockFragment.instantiate(mActivity, mClass.getName()); ft.add(android.R.id.content, mFragment, mTag); } else if (mFragment != null) { // If it exists, simply attach it in order to show it ft.attach(mFragment); } else if (preInitializedFragment != null) { ft.attach(preInitializedFragment); mFragment = preInitializedFragment; } } 

  public static class TabListener<T extends SherlockFragment> implements ActionBar.TabListener { private SherlockFragment mFragment; private final SherlockFragmentActivity mActivity; private final String mTag; private final Class<T> mClass; /** Constructor used each time a new tab is created. * @param activity The host Activity, used to instantiate the fragment * @param tag The identifier tag for the fragment * @param clz The fragment's Class, used to instantiate the fragment */ public TabListener(Activity activity, String tag, Class<T> clz) { mActivity = (SherlockFragmentActivity) activity; mTag = tag; mClass = clz; } public void onTabSelected(Tab tab, FragmentTransaction ft) { // Check if the fragment has already been initialised SherlockFragment preInitializedFragment = (SherlockFragment) mActivity.getSupportFragmentManager().findFragmentByTag(mTag); if (mFragment != null) { // If it exists, simply attach it in order to show it ft.attach(mFragment); } else if (preInitializedFragment != null) { mFragment = preInitializedFragment; ft.attach(mFragment); } else { // Not found, so instantiate and add it to the activity mFragment = (SherlockFragment) SherlockFragment.instantiate(mActivity, mClass.getName()); ft.add(android.R.id.content, mFragment, mTag); } } public void onTabUnselected(Tab tab, FragmentTransaction ft) { if (mFragment != null) { // Detach the fragment, because another one is being attached ft.detach(mFragment); } } public void onTabReselected(Tab tab, FragmentTransaction ft) { // User selected the already selected tab. Usually do nothing. } }
