POjava.lang.IllegalStateException: Activity has been destroyed using fragments
text
Body
copied!<p>For two days now I'm trying to solve this problem. I've searched online and on stackoverflow, but I can't find a answer to my question.</p> <p>In my App I'm trying to implement two tabs. One needs to show a map, and in the other tab I will show a list adapter. (using <a href="http://actionbarsherlock.com/" rel="nofollow">ActionBarSherlock</a>)</p> <p>When I click on the second tab and then click back on the first one I get a exception:</p> <blockquote> <p>10-08 01:27:45.203: E/AndroidRuntime(7082): java.lang.IllegalStateException: Activity has been destroyed</p> </blockquote> <p>Here's my activity code and my fragment class. (just for test, I put CustomMapFragment class twice).</p> <pre><code> public class MapActivity extends SherlockFragmentActivity implements LocationListener,TabListener{ LatLng mLocation; GoogleMap map; //CustomMapFragment fragment1 = new CustomMapFragment(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //FragmentManager fm = getSupportFragmentManager(); if (savedInstanceState == null) { setContentView(R.layout.activity_main); FragmentManager fm = getSupportFragmentManager(); setActionBar(); //fragment2 = new Fragment2(); //FragmentTransaction ft = fm.beginTransaction(); //ft.add(R.id.container, fragment1, "frag1"); //ft.add(R.id.fragment_container, fragment2, "frag2"); //ft.commit(); } } private void setActionBar() { ActionBar actionBar = getSupportActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); CustomMapFragment frag1 = new CustomMapFragment(); CustomMapFragment frag2 = new CustomMapFragment(); Tab tab1 = actionBar.newTab() .setText("Frag1") .setTabListener(new NavTabListener(frag1)); actionBar.addTab(tab1); Tab tab2 = actionBar.newTab() .setText("Frag2") .setTabListener(new NavTabListener(frag2)); actionBar.addTab(tab2); } protected class NavTabListener implements ActionBar.TabListener { private Fragment fragment; public NavTabListener(Fragment fragment) { this.fragment = fragment; } public void onTabSelected(Tab tab, FragmentTransaction ft) { ft.replace(R.id.container, fragment); } public void onTabUnselected(Tab tab, FragmentTransaction ft) { FragmentManager fm = getSupportFragmentManager(); ft = fm.beginTransaction(); ft.remove(fragment); ft.commit(); } public void onTabReselected(Tab tab, FragmentTransaction ft) { } } @Override public void onTabSelected(Tab tab, FragmentTransaction ft) { // TODO Auto-generated method stub } @Override public void onTabUnselected(Tab tab, FragmentTransaction ft) { // TODO Auto-generated method stub } @Override public void onTabReselected(Tab tab, FragmentTransaction ft) { // TODO Auto-generated method stub } @Override public void onLocationChanged(Location location) { // TODO Auto-generated method stub } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } @Override public void onResume() { super.onResume(); } @Override public void onPause() { super.onPause(); } } public class CustomMapFragment extends SherlockFragment{ private SupportMapFragment fragment; private GoogleMap map; public CustomMapFragment(){ super(); } @Override public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){ super.onCreate(savedInstanceState); View lView = inflater.inflate(R.layout.map_fragment , null); return lView; } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); FragmentManager fm = getChildFragmentManager(); fragment = (SupportMapFragment) fm.findFragmentById(R.id.map); if (fragment == null) { fragment = SupportMapFragment.newInstance(); fm.beginTransaction().replace(R.id.map, fragment).commit(); } } @Override public void onResume() { super.onResume(); if (map == null) { map = fragment.getMap(); map.addMarker(new MarkerOptions().position(new LatLng(0, 0))); } } } </code></pre> <p>Thanks in advance!</p>
