我正在使用片段,并希望在各种活动中分享它。但是,一旦我转向其他活动,它就会显示出来。这是活动:
public class ViewStubDemoActivity extends FragmentActivity
{
public static ViewStub adStub;
private AdFragment adFragment;
public static FragmentManager fragmentManager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setHeader("ViewStub -> Header demo");
if(fragmentManager == null)
fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
adFragment = (AdFragment)fragmentManager.findFragmentByTag("fragment");
if(adFragment == null)
{
adFragment = new AdFragment();
fragmentTransaction.add (adFragment, "fragment");
fragmentTransaction.replace(R.id.ad_fragment_linearLayout, adFragment);
fragmentTransaction.commit();
}
else
{
fragmentTransaction.replace(R.id.ad_fragment_linearLayout, adFragment);
fragmentTransaction.commit();
}
}
public void setHeader(String title)
{
ViewStub stub = (ViewStub) findViewById(R.id.vsHeader);
View inflated = stub.inflate();
TextView txtTitle = (TextView) inflated.findViewById(R.id.txtHeading);
txtTitle.setText(title);
}
public void changeActivity(View v)
{
Intent intent = new Intent(this, ViewStubDemoActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
intent = null;
finish();
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
return;
}
}
这是片段:
public class AdFragment extends Fragment
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.setRetainInstance(true);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.ad_banner_layout, container, false);
ViewGroup adBannerLinearLayout = (ViewGroup)view.findViewById(R.id.adBannerLayout);
InMobiBanner inMobiBanner = new InMobiBanner(getActivity());
inMobiBanner.loadInmobiBannerAd(adBannerLinearLayout);
inMobiBanner = null;
return view;
}
}
请帮帮我。我尽了最大努力但没有用。
