Fragments are a portion of an Activity:
Load a fragment Activity to call a fragment :
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
} }
activity_main :<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<fragment
android:id="@+id/titles"
android:layout_width="0px"
android:layout_height="match_parent"
android:layout_weight="1"
class="com.example.googlefragment.TitlesFragment"/>
//calls the fragment
</LinearLayout>
TitlesFragment :public class TitlesFragment extends android.support.v4.app.ListFragment {
boolean mDualPane;
int mCurCheckPosition = 0;
String titles[] = { "Item one", "Item two", "Item three" };
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Populate list with our static array of titles.setListAdapter(new ArrayAdapter(getActivity(),
android.R.layout.simple_dropdown_item_1line,titles));
// Check to see if we have a frame in which to embed the details
// fragment directly in the containing UI.
View detailsFrame = getActivity().findViewById(R.id.details);
mDualPane = detailsFrame != null && detailsFrame.getVisibility() == View.VISIBLE;
if (savedInstanceState != null) {
// Restore last state for checked position.
mCurCheckPosition = savedInstanceState.getInt("curChoice", 0);
}
if (mDualPane) {
// In dual-pane mode, the list view highlights the selected item.
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
// Make sure our UI is in the correct state.
showDetails(mCurCheckPosition);
}else
{
System.out.println("NOT DUAL");
} }
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("curChoice", mCurCheckPosition);
}
@Override
public void onListItemClick(ListView l, View v,int position,long id) {

// We can display everything in-place with fragments,so update
// the list to highlight the selected item and show the data.

// Check what fragment is currently shown,replace if needed.
DetailsFragment details = (DetailsFragment)
getFragmentManager().findFragmentById(R.id.details);

} else {

// the dialog fragment with selected text.
Intent intent = new Intent();

} }}
