    text
    copied!<p>I'm using a ListView which drives a detail view. The List view and Detail view have their own activities. The detail view displays a map in a smaller layout. The code for map fragment is as follows:</p> <pre class="lang-xml prettyprint-override"><code>&lt;RelativeLayout android:layout_width="fill_parent" android:layout_height="150dp" android:id="@+id/details_emap_container" android:background="@drawable/back_rounded_rectangle_border_black" android:padding="2dp" &gt; &lt;fragment xmlns:android="http://schemas.android.com/apk/res/android" android:tag="details_map_short" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment" /&gt; &lt;ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/rightArrowMap" android:src="@drawable/right_arrow_black" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:layout_marginRight="10dp"/&gt; &lt;/RelativeLayout&gt; </code></pre> <p>The first time I click on a list item when in a two pane layout on a tablet, it works fine. But on subsequently selecting any other list item, following error is thrown:</p> <pre class="lang-java prettyprint-override"><code>android.view.InflateException: Binary XML file line #159: Error inflating class fragment at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:688) at android.view.LayoutInflater.rInflate(LayoutInflater.java:724) at android.view.LayoutInflater.rInflate(LayoutInflater.java:727) at android.view.LayoutInflater.rInflate(LayoutInflater.java:727) at android.view.LayoutInflater.rInflate(LayoutInflater.java:727) at android.view.LayoutInflater.inflate(LayoutInflater.java:479) at android.view.LayoutInflater.inflate(LayoutInflater.java:391) at com.xxxx.android.activity.fragments.EventDetailFragment.onCreateView(EventDetailFragment.java:97) at android.support.v4.app.Fragment.performCreateView(Fragment.java:1460) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:911) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1088) at android.support.v4.app.BackStackRecord.run(BackStackRecord.java:682) at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1444) at android.support.v4.app.FragmentManagerImpl$1.run(FragmentManager.java:429) at android.os.Handler.handleCallback(Handler.java:587) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:132) at android.app.ActivityThread.main(ActivityThread.java:4123) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:491) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:841) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:599) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.IllegalArgumentException: Binary XML file line #159: Duplicate id 0xffffffff, tag details_map_short, or parent id 0x0 with another fragment for com.google.android.gms.maps.SupportMapFragment at android.support.v4.app.FragmentActivity.onCreateView(FragmentActivity.java:285) at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:660) ... 22 more </code></pre> <p>The EventDetailFragment looks like this:</p> <pre class="lang-java prettyprint-override"><code>@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { Log.e(TAG, "onCreateView was called!"); // If activity recreated (such as from screen rotate), restore // the previous article selection set by onSaveInstanceState(). // This is primarily necessary when in the two-pane layout. if (savedInstanceState != null) { mCurrentPosition = savedInstanceState.getInt(ARG_POSITION); mCurrEventId = savedInstanceState.getString(EVENT_ID); } // Inflate the layout for this fragment detailsView = inflater.inflate(R.layout.fragment_event_detail, container, false); mMapFragment = (SupportMapFragment)getFragmentManager().findFragmentByTag(MAP_FRAGMENT_TAG); // We can't be guaranteed that the map is available because Google Play services might // not be available. //setUpMapIfNeeded(); //do this later in onStart return detailsView; } </code></pre> <p>The code in List activity to display the detail activity or fragment when an item is slected:</p> <pre class="lang-java prettyprint-override"><code>@Override public void onItemSelected(int index) { Log.d(TAG, "Item Selected is : " + index); if(findViewById(R.id.event_details_container) != null) { // In two-pane mode, show the detail view in this activity by // adding or replacing the detail fragment using a // fragment transaction. Log.d(TAG, "Two pane layout navigation executed"); Bundle arguments = new Bundle(); arguments.putInt(EventDetailFragment.ARG_POSITION, index); EventDetailFragment fragment = new EventDetailFragment(); fragment.setArguments(arguments); getSupportFragmentManager().beginTransaction() .replace(R.id.event_details_container, fragment).commit(); } else { // In single-pane mode, simply start the detail activity // for the selected item ID. Log.d(TAG, "Single pane layout navigation - creating new Activity to display!"); getSupportFragmentManager().executePendingTransactions(); Intent detailIntent = new Intent(this, EventDetailActivity.class); detailIntent.putExtra(EventDetailFragment.ARG_POSITION, index); startActivity(detailIntent); } } </code></pre> <p>I'm not able to figure out why this doesn't work when in two pane layout? And why only the MapFragment seems to throw the error? This was all working just fine until I added the <code>SupportMapFragment</code>. Any help/ideas will be appreciated!</p> <p>PS: The code has to be supported for API level 10 onwards.</p>
