I'm very bad in explaining things, i'll try to do my best :)
I was trying to use a Tabhost and display list fragments in each tab.
[ListFragments in tabview]:
This is how it looks.
On click on the list element, another fragment is invoked to display the details, it's displaying as below.
[Onclick on the list elements]:
There are 2 problems.
When i go back to the tab view and click on the list it says :
"java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread
. [in ListView(16908298, class android.widget.ListView) with Adapter(class android.widget.SimpleAdapter)]
"
TabView xml:
<TabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"

java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification.
Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ListView(16908298, class android.widget.ListView) with Adapter(class android.widget.SimpleAdapter)] "
Please call notifyDataSetChanged()
and yourListView.requestLayout()
in the UI thread after adding items.The problem is that your collection that bound to Adapter is changed in the Background thread. Hence the solution is moving it to UI thread(as I stated above) or simply wrapping it with runOnUiThread()
.
runOnUiThread(new Runnable() {
public void run() {
your_collection.add(item);
your_adapter.notifyDataSetChanged();
yourListView.requestLayout();
}
});
To call another fragment the current:
SecondFragment secFrag = new SecondFragment();
FragmentTransaction fragTransaction = getFragmentManager().beginTransaction();
fragTransaction.replace(R.id.frame_fragment,secFrag );
fragTransaction.addToBackStack(null);
fragTransaction.commit();
EDIT:
To Display Detail fragment full Screen, please make following changes:
In your scrollView
Replace android:layout_height="wrap_content"
with android:layout_height="fill_parent"
In your TableLayout
Replace android:layout_height="wrap_content"
with android:layout_height="fill_parent"

Use hadler to notify your list because you can not access any UIComponents from background or worker thread, so it must be access from UI Thread. To ensure that use following trick.
Handler mHandler = new Handler();
mHandler.post(new Runnable() {
@Override
public void run() {
listadapter.notifyDataSetChanged();
}
});

Try this example
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Search fragment = new Search();
fragmentTransaction.add(R.id.mainLayout,fragment , "MY_FRAG");
fragmentTransaction.commit();
It really helped you to use fragment from another fragment.

For the above You need to simply add a fragment you just need an instance of:
For example-
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Search fragment = new Search();
fragmentTransaction.add(R.id.mainLayout,fragment , "MY_FRAG");
fragmentTransaction.commit();
