Android tabHost frenos vistas de lista enArticleSelected
Tengo una actividad de Cajón principal que carga mis fragmentos cuando se selecciona un elemento del cajón. El fragmento que está cargado contiene un tabhost que aloja múltiples fragmentos para que pueda cambiar a través de pestañas.
Antes de Tabs, tenía un fragmento con un montón de botones que al hacer clic reemplazaban el fragmento actual por uno nuevo. Todos los fragmentos tienen vistas de lista y, cuando hace clic en un elemento, reemplaza el fragmento de vista de lista actual por otro fragmento.
Mi problema es que cuando coloqué todos mis fragmentos en un tabhost, ArticleOnSelected ya no funciona, y forzar el cierre de mi aplicación cuando se selecciona un elemento de la vista de lista. Aquí hay un ejemplo de uno de los errores de FC:

Veo que el problema es con la vista, y creo que no puede acceder al marco principal desde el diseño que contiene todos los fragmentos con el cajón de navegación.
Mi clase MainDrawer2 es lo que se abre primero y es donde se cargan el cajón y los fragmentos. El codigo es:
public class MainDrawer2 extends FragmentActivity
{
private static final String EXTRA_NAV_ITEM = "extraNavItem";
private static final String STATE_CURRENT_NAV = "stateCurrentNav";
private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;
private NavDrawerListAdapter mDrawerAdapter;
private ListView mDrawerList;
private CharSequence mTitle;
private CharSequence mDrawerTitle;
private MainNavItem mCurrentNavItem;
public static Intent createLaunchFragmentIntent(Context context, MainNavItem navItem)
{
return new Intent(context, MainDrawer2.class)
.putExtra(EXTRA_NAV_ITEM, navItem.ordinal());
}
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
mTitle = mDrawerTitle = getTitle();
mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
mDrawerList = (ListView)findViewById(R.id.drawer);
getActionBar().setDisplayHomeAsUpEnabled(true);
enableHomeButtonIfRequired();
mDrawerAdapter = new NavDrawerListAdapter(getApplicationContext());
mDrawerList.setAdapter(mDrawerAdapter);
mDrawerList.setOnItemClickListener(new ListView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
displayNavFragment((MainNavItem)parent.getItemAtPosition(position));
}
});
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.app_name, R.string.app_name)
{
public void onDrawerClosed(View view)
{
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView)
{
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if(getIntent().hasExtra(EXTRA_NAV_ITEM)){
MainNavItem navItem = MainNavItem.values()
[getIntent().getIntExtra(EXTRA_NAV_ITEM,
MainNavItem.STATISTICS.ordinal())];
displayNavFragment(navItem);
}
else if(savedInstanceState != null){
mCurrentNavItem = MainNavItem.values()
[savedInstanceState.getInt(STATE_CURRENT_NAV)];
setCurrentNavItem(mCurrentNavItem);
}
else{
displayNavFragment(MainNavItem.STATISTICS);
}
}
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
private void enableHomeButtonIfRequired()
{
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH){
getActionBar().setHomeButtonEnabled(true);
}
}
@Override
public void setTitle(CharSequence title)
{
mTitle = title;
getActionBar().setTitle(mTitle);
}
@Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggles
mDrawerToggle.onConfigurationChanged(newConfig);
}
@Override
protected void onSaveInstanceState(Bundle outState)
{
super.onSaveInstanceState(outState);
outState.putInt(STATE_CURRENT_NAV, mCurrentNavItem.ordinal());
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
/*
@Override
public boolean onPrepareOptionsMenu(Menu menu)
{
// if nav drawer is opened, hide the action items
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
*/
private void displayNavFragment(MainNavItem navItem)
{
if(navItem == mCurrentNavItem){
return;
}
Fragment fragment = Fragment.instantiate(this,
navItem.getFragClass().getName());
if(fragment != null){
getSupportFragmentManager().beginTransaction()
.replace(R.id.main, fragment)
.commit();
setCurrentNavItem(navItem);
}
}
private void setCurrentNavItem(MainNavItem navItem)
{
int position = navItem.ordinal();
// If navItem is in DrawerAdapter
if(position >= 0 && position < mDrawerAdapter.getCount()){
mDrawerList.setItemChecked(position, true);
}
else{
// navItem not in DrawerAdapter, de-select current item
if(mCurrentNavItem != null){
mDrawerList.setItemChecked(mCurrentNavItem.ordinal(), false);
}
}
mDrawerLayout.closeDrawer(mDrawerList);
setTitle(navItem.getTitleResId());
mCurrentNavItem = navItem;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
if(mDrawerLayout.isDrawerOpen(mDrawerList)) {
mDrawerLayout.closeDrawer(mDrawerList);
}
else {
mDrawerLayout.openDrawer(mDrawerList);
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public void goToSearch(MenuItem item){
//go to search page
Fragment Fragment_one;
FragmentManager man= getSupportFragmentManager();
FragmentTransaction tran = man.beginTransaction();
Fragment_one = new Search();
tran.replace(R.id.main, Fragment_one);//tran.
tran.addToBackStack(null);
tran.commit();
}
}
El fragmento predeterminado que se carga es el fragmento que contiene mi tabhost y crea las pestañas:
public class StatisticsTab extends Fragment {
private FragmentTabHost mTabHost;
//Mandatory Constructor
public StatisticsTab() {
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_tabs,container, false);
mTabHost = (FragmentTabHost)rootView.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("Basic").setIndicator("Basic"),
StatisticsPage.class, null);
mTabHost.addTab(mTabHost.newTabSpec("Brewery").setIndicator("Brewery"),
BreweryStatistics.class, null);
mTabHost.addTab(mTabHost.newTabSpec("Style").setIndicator("Style"),
StyleStatistics.class, null);
mTabHost.addTab(mTabHost.newTabSpec("Taste").setIndicator("Taste"),
TasteStatisticsPage.class, null);
return rootView;
}
}
Si hago clic en un elemento en mi pestaña y aparece la vista de lista de esta manera:
Me da el FC que publiqué arriba. El código para este fragmento es:
public class BreweryStatistics extends Fragment implements GetBreweryStatisticsJSON.OnArticleSelectedListener {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.brewery_statistics_layout, container, false);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
String userName = prefs.getString("userName", null);
String userID = prefs.getString("userID", null);
String url = "myURL";
//async task to get beer taste tag percents
GetBreweryStatisticsJSON task = new GetBreweryStatisticsJSON(getActivity());
task.setOnArticleSelectedListener(this);
task.execute(url);
// Inflate the layout for this fragment
return v;
}
@Override
public void onArticleSelected(String bID){
//code to execute on click
Fragment Fragment_one;
FragmentManager man= getFragmentManager();
FragmentTransaction tran = man.beginTransaction();
Fragment_one = new BreweryPage2();
final Bundle bundle = new Bundle();
bundle.putString("breweryIDSent", bID);
Fragment_one.setArguments(bundle);
tran.replace(R.id.main, Fragment_one);//tran.
tran.addToBackStack(null);
tran.commit();
}
}
Y cuando se ejecuta el onArticleSelected anterior, no carga el nuevo fragmento. En teoría, qué debería suceder el Fragmento que contiene el tabhostStatisticsTab debe reemplazarse con el nuevo Fragmento en elOnArticleSelected
