J'ai un problème avec mon application .. Je dois changer un fragment dans un onglet, mais quand je fais cela, le nouveau fragment se chevauchent sur l'ancien fragment. Ceci est mon code:ActionBarSherlock fragment chevauchant dans le même onglet
MainActivity:
public class MainActivity extends SherlockFragmentActivity {
ViewPager mViewPager;
TabsAdapter mTabsAdapter;
TextView tabCenter;
TextView tabText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
mViewPager = new ViewPager(this);
mViewPager.setId(R.id.pager);
setContentView(mViewPager);
ActionBar bar = getSupportActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setDisplayOptions(0, ActionBar.DISPLAY_SHOW_TITLE);
mTabsAdapter = new TabsAdapter(this, mViewPager);
mTabsAdapter.addTab(bar.newTab().setText("Home"),
FragmentTab1.class, createBundle("ft1"));
mTabsAdapter.addTab(bar.newTab().setText("FujiSan"),
FragmentTab2.class, null);
}
public static class TabsAdapter extends FragmentPagerAdapter implements
ActionBar.TabListener, ViewPager.OnPageChangeListener {
private final Context mContext;
private final ActionBar mActionBar;
private final ViewPager mViewPager;
private final ArrayList<TabInfo> mTabs = new ArrayList<TabInfo>();
static final class TabInfo {
private final Class<?> clss;
private final Bundle args;
TabInfo(Class<?> _class, Bundle _args) {
clss = _class;
args = _args;
}
}
public TabsAdapter(SherlockFragmentActivity activity, ViewPager pager) {
super(activity.getSupportFragmentManager());
mContext = activity;
mActionBar = activity.getSupportActionBar();
mViewPager = pager;
mViewPager.setAdapter(this);
mViewPager.setOnPageChangeListener(this);
}
public void addTab(ActionBar.Tab tab, Class<?> clss, Bundle args) {
TabInfo info = new TabInfo(clss, args);
tab.setTag(info);
tab.setTabListener(this);
mTabs.add(info);
mActionBar.addTab(tab);
notifyDataSetChanged();
}
@Override
public int getCount() {
return mTabs.size();
}
@Override
public Fragment getItem(int position) {
TabInfo info = mTabs.get(position);
return Fragment.instantiate(mContext, info.clss.getName(),
info.args);
}
@Override
public void onPageScrolled(int position, float positionOffset,
int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
mActionBar.setSelectedNavigationItem(position);
}
@Override
public void onPageScrollStateChanged(int state) {
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
Object tag = tab.getTag();
for (int i = 0; i < mTabs.size(); i++) {
if (mTabs.get(i) == tag) {
mViewPager.setCurrentItem(i);
}
}
}
@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
}
public static Bundle createBundle(String title) {
Bundle bundle = new Bundle();
bundle.putString("title", title);
return bundle;
}
}
J'ai deux onglets et j'ajouter à ces deux fragments. Cette la mise en page:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/home"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</android.support.v4.view.ViewPager>
Et voici le code de FragmentTab1:
public class FragmentTab1 extends SherlockFragment {
static Context context;
@Override
public SherlockFragmentActivity getSherlockActivity() {
return super.getSherlockActivity();
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
RelativeLayout view = (RelativeLayout) inflater.inflate(
R.layout.fragmenttab1, container, false);
context = getActivity();
Button guasti = (Button) view.findViewById(R.id.bGuasti);
Button segnala = (Button) view.findViewById(R.id.segnalaDisservizio);
guasti.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Fragment newFragment = new FragmentTab2();
FragmentTransaction transaction = getFragmentManager()
.beginTransaction();
transaction.replace(R.id.frame1, newFragment, "new frsg");
transaction.addToBackStack(null);
transaction.commit();
getFragmentManager().executePendingTransactions();
}
});
Avec une mise en page qui ont un frameLayout:
...omissis...
<FrameLayout
android:id="@+id/frame1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true" >
</FrameLayout>
Cette le résultat: en Thera rouge sont les composants du second fragment
