In my calendar application, I am using ActionBarSherlock to display two tabs - 1) Calendar 2) Converter. On the click event of an ActionBar menu item, I'm using SlidingMenu drawer to display event summary for that month.
I want to use viewpager specifically for the Calendar tab and I have implemented it this way:
Main.java:
public class BaseActivity extends SlidingSherlockFragmentActivity
{
private ViewPager pager;
CalendarFragmentPagerAdapter mPagerAdapter;
private static final int MONTHS_LIMIT = 5;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTitle(R.string.app_name);
setContentView(R.layout.main);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.main, new CalendarFragment())
.commit();
setBehindContentView(R.layout.content_frame);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.content_frame, new EventsSummary())
.commit();
setSlidingActionBarEnabled(false);
final ActionBar bar = getSupportActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setHomeButtonEnabled(true);
ActionBar.Tab calendar = bar.newTab();
ActionBar.Tab converter = bar.newTab();
calendar.setText(this.getResources().getString(R.string.calendar));
converter.setText(this.getResources().getString(R.string.converter));
calendar.setTabListener(new MyTabListener());
converter.setTabListener(new MyTabListener());
bar.addTab(calendar);
bar.addTab(converter);
// customize the SlidingMenu
SlidingMenu sm = getSlidingMenu();
sm.setShadowWidthRes(R.dimen.shadow_width);
sm.setShadowDrawable(R.drawable.shadow);
sm.setBehindOffsetRes(R.dimen.actionbar_home_width);
sm.setSlidingEnabled(false);
mPagerAdapter = new CalendarFragmentPagerAdapter(getSupportFragmentManager());
pager = (ViewPager) this.findViewById(R.id.viewpager);
pager.setAdapter(mPagerAdapter);
pager.setCurrentItem(MONTHS_LIMIT / 2);
}
private class MyTabListener implements ActionBar.TabListener
{
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if(tab.getPosition()==0)
{
CalendarFragment frag = new CalendarFragment();
ft.replace(R.id.main, frag);
}
else
{
ConverterFragment frag = new ConverterFragment();
ft.replace(R.id.main, frag);
}
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
}
public boolean onOptionsItemSelected(MenuItem item) {
Intent newActivity;
// Handle item selection
switch (item.getItemId()) {
case R.id.menu_slidingmenu:
toggle();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public class CalendarFragmentPagerAdapter extends FragmentPagerAdapter {
public CalendarFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
CalendarFragment fragment = new CalendarFragment();
Bundle args = new Bundle();
args.putInt("offset", position - MONTHS_LIMIT / 2);
fragment.setArguments(args);
return fragment;
}
#Override
public int getCount() {
return MONTHS_LIMIT;
}
}
}
CalendarFragment.java:
public class CalendarFragment extends Fragment
{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle args = getArguments();
int offset = args.getInt("offset"); //throws NullPointerException
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.simple_calendar_view, container, false);
.....
return v;
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putBoolean("dummy", true);
}
}
The problem is at this line in the CalendarFragment:
int offset = args.getInt("offset");
It throws the error NullPointerException and debugging shows this is because Bundle args = getArguments() is null.
I tried to put the breakpoint at this line in the PagerAdapter:
Bundle args = new Bundle();
but it never reaches here and the application crashes throwing the NullPointerException.
Where am I going wrong?
Here
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.main, new CalendarFragment())
.commit();
and here
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if (tab.getPosition() == 0) {
CalendarFragment frag = new CalendarFragment();
ft.replace(R.id.main, frag);
} else {
ConverterFragment frag = new ConverterFragment();
ft.replace(R.id.main, frag);
}
}
you're just creating an empty CalendarFragment instance without any arguments.
So your activity launches, creating an empty Fragment without arguments, and then crashes when trying to get those

This is the first time I work with Fragments and I don't understand very well how to manage them. In this case I have two fragments that I show dinamically in a FrameLayout with id fragment_place. The issue is probably with the fragmentTransaction(addtobackstack / popbackstack).
In Fragment2 I show a popupmenu when I press the menubutton on the mobile and it works as expected the first time, but after I go back to the previous fragment and return to fragment2 now If I press the menubutton I get the following error
java.lang.NullPointerException
at android.support.v7.view.menu.MenuBuilder.<init>(MenuBuilder.java:216)
at android.support.v7.widget.PopupMenu.<init>(PopupMenu.java:103)
at android.support.v7.widget.PopupMenu.<init>(PopupMenu.java:78)
at android.support.v7.widget.PopupMenu.<init>(PopupMenu.java:63)
at package.Fragment2.showPopup(Fragment2.java:93)
Below is the code for the mainactivity and fragment2, this is driving me crazy, any help will be much appreciated.
public class MainActivity extends AppCompatActivity implements Fragment1.onEvent {
Fragment1 frag;
Fragment2 frag2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
frag = new Frag1();
// Begin the transaction
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.fragment_place, frag);
ft.commit();
}
#Override
public void onEventSelected(String key) {
frag2 = new Frag2();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.fragment_place,frag2);
ft.addToBackStack(null);
ft.commit();
}
#Override
public void onBackPressed(){
FragmentManager ft = getSupportFragmentManager();
if (ft.getBackStackEntryCount() > 0) {
ft.popBackStack();
} else {
super.onBackPressed();
}
}
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
int action = event.getAction();
int keyCode = event.getKeyCode();
switch (keyCode) {
case KeyEvent.KEYCODE_MENU:
if (action == KeyEvent.ACTION_UP) {
Fragment f = getSupportFragmentManager().findFragmentById(R.id.fragment_place);
if (f instanceof Fragment2) {
sendBroadcast();
}
}
return true;
default:
return super.dispatchKeyEvent(event);
}
}
private void sendBroadcast(){
Intent intent = new Intent("popup_menu");
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
}}
This is the problematic fragment. The error lines are basically the method showPopup
public class Fragment2 extends Fragment {
private String key;
private View view;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment, parent, false);
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(mMessageReceiver,
new IntentFilter("popup_menu"));
return view;
}
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
showPopup(view);
}
};
public void showPopup(View v) {
Button b = (Button) view.findViewById(R.id.b_attach);
PopupMenu popup = new PopupMenu(getActivity(), b);
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
//dosomething
}
});
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.menu_popup, popup.getMenu());
popup.show();
}}
this is the way i do and it works for me:
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame,new fragment() ).commit();
I solved the issue getting rid of sendbroadcast() and broadcastReceiver(), instead of that now I call showPopup() directly from the mainActivity when I need it.

I am doing an Android app using fragments but i haven't previously experience with fragments.
I have a main FragmentActivity where i load a main view and i call my fragment class:
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_view);
FragmentTransaction FT = getFragmentManager().beginTransaction();
if (findViewById(R.id.fragmentAction) != null) {
FT.replace(R.id.fragmentAction, MainMenuFragment.newInstance(
getString(R.string.main_menu), getApplicationContext()));
}
FT.addToBackStack(null);
FT.commit();
}
#Override
public void onBackPressed() {
}
And this is my fragmet classm where when i push button call to other fragment:
public class MainMenuFragment extends Fragment {
private static String my_description = "";
private static Context my_context = null;
public static MainMenuFragment newInstance(String description,
Context context) {
my_description = description;
my_context = context;
MainMenuFragment f = new MainMenuFragment();
return f;
}
public MainMenuFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View view = null;
if (my_description.compareTo(getString(R.string.main_menu)) == 0) {
view = inflater.inflate(R.layout.main_menu, container, false);
}
return view;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (my_description.compareTo(getString(R.string.main_menu)) == 0) {
Button new_user = (Button) getView().findViewById(
R.id.button_newUser);
new_user.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
FragmentTransaction FT = getFragmentManager()
.beginTransaction();
FT.replace(R.id.fragmentAction, LdapFragment.newInstance(
getString(R.string.new_user), my_context));
FT.commit();
}
});
}
}
}
My question is: how can i do to return to previously fragment when i push back key? I add onBackPressed function in my FragmentActivity and capture the event, but what have i to do?
Use this code
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
if (getSupportFragmentManager().getBackStackEntryCount() == 0) {
this.finish();
} else {
getSupportFragmentManager().popBackStack();
removeCurrentFragment();
}
}
public void removeCurrentFragment() {
FragmentTransaction transaction = getSupportFragmentManager()
.beginTransaction();
Fragment currentFrag = getSupportFragmentManager().findFragmentById(
R.id.fragment_container);
setFragName("NONE");
if (currentFrag != null) {
setFragName(currentFrag.getClass().getSimpleName());
}
if (currentFrag != null) {
transaction.remove(currentFrag);
}
transaction.commit();
}
following is the code that i use. You need not do anything. Android system handles backpress and shows the appropriate fragment in the navigation order
#Override
public void onBackPressed() {
super.onBackPressed();
if (getFragmentManager().getBackStackEntryCount() == 0)
finish();
}
you missed the super.onBackPressed(); call. Try adding that to your code.
Just create method for add and back to fragment .
for example,
public void setFragment(Fragment fragment, boolean backStack, String tag) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = manager.beginTransaction();
if (backStack) {
fragmentTransaction.addToBackStack(tag);
}
fragmentTransaction.replace(R.id.fragmentAction, MainMenuFragment.newInstance(
getString(R.string.main_menu), tag);
fragmentTransaction.commit();
}
call method from onCreate() or onResume()of your Activity.
setFragment(Your FragmentClass object, true, "tag");
i have four tabs in the tab bar when i select the contact tab from the tab bar the tab bar is disappeared.i want to show the tab bar when i select the contact tab.
Here is code
TabActivity.java
public class Tab_Activity extends TabActivity
{
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Resources obj_res = getResources();
TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);
TabSpec m_tab1 = tabHost.newTabSpec("First Tab");
TabSpec m_tab2 = tabHost.newTabSpec("Second Tab");
Intent intent1 = new Intent().setClass(this, Phone.class);
Intent intent3 = new Intent().setClass(this, Settings.class);
Intent intent4 = new Intent().setClass(this, Contact.class);
m_tab4.setIndicator("Tab4");
m_tab4=tabHost.newTabSpec("tab4").setIndicator("", obj_res.getDrawable(R.drawable.pic1)).setContent(intent3);
m_tab5.setIndicator("Tab4");
m_tab5=tabHost.newTabSpec("tab4").setIndicator("", obj_res.getDrawable(R.drawable.pic3)).setContent(intent4);
tabHost.addTab(m_tab2);
tabHost.addTab(m_tab4);
tabHost.addTab(m_tab5);
}}
Contact.java
public class Contact extends Activity
{
protected void onCreate(Bundle savedInstanceState)
{
//this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
//setContentView(R.layout.contact);
Intent Contacts = new Intent(Intent.ACTION_GET_CONTENT);
Contacts.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
Contacts.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
startActivityForResult(Contacts, 1);
}}
This is your activity in which u can put how many tab you want to display.
public class GuestListAdminActivity extends FragmentActivity implements
ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Bride", "Groom", "Create Gueset List" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_guest_list_admin);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
getActionBar().setHomeButtonEnabled(true);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
This is pager adapter which will show your all fragments.
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new BrideGuestList();
case 1:
return new GroomGuestList();
case 2:
return new NewGuestListActivity();
default:
break;
}
return null;
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return 3;
}
}
And make your fragment activity like following
public class BrideGuestList extends android.support.v4.app.Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.bride_guest_list, container, false);
return rootView;
}
I have a map activity. When I click on the info window of the marker an intent will send the id to my fragment. In my map activity :
map.setOnInfoWindowClickListener(
new OnInfoWindowClickListener() {
#Override
public void onInfoWindowClick(Marker m) {
Intent nextScreen = new Intent (Map.this,
PHDetail.class);
Bundle bundle = new Bundle();
bundle.putString("test", "id");
Callfor c = new Callfor();
c.setArguments(bundle);
startActivityForResult(nextScreen, 101);
}
});
In my fragment :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_call_for, container, false);
TextView TXT = (TextView) rootView.findViewById(R.id.test);
Bundle test = getArguments();
if(test!=null){
String d = test.getString("test", " ");
TXT.setText(d);
}
return rootView;
}
The problem is the bundle is null. How can I fix this?
This is my PHDetail FragmentActivity class :
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.phdetail);
Intent intent = getIntent();
if (intent != null) {
String id = intent.getStringExtra("test");
}
// Initialization :
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs :
for (String tab_name : tabs){
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
UPDATE
On your onTabSelected you need to create your Fragment, set the bundle and then do the transaction like this.
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
Bundle bundle = new Bundle();
bundle.putString("id", id);
MyFragment fragment=new MyFragment();
fragment.setArguments(bundle);
ft = getFragmentManager().beginTransaction();
ft.add(R.id.fragment_container,fragment);
ft.commit();
}
FIRST ANSWER
The right way to pass values to other Activities like a FragmentActivity it´s adding those values to the intent that´s going to start them.
map.setOnInfoWindowClickListener(
new OnInfoWindowClickListener() {
#Override
public void onInfoWindowClick(Marker m) {
Intent nextScreen = new Intent (Map.this, PHDetail.class);
intent.putExtra("test", "id");
startActivityForResult(nextScreen, 101);
}
});
Then on your FragmentActivity called PHDetail you should get the values from the Intent.
Intent intent = getIntent();
if (intent != null) {
String id = intent.getStringExtra("test");
}
After that when you load your Fragment on your container view on PHDetail, you should add the Bundle and then do the transaction.
Bundle bundle = new Bundle();
bundle.putString("test", "id");
Callfor c = new Callfor();
c.setArguments(bundle);
After that you'll be able to retrieve the values inside your Fragment like you stated above
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_call_for, container, false);
TextView TXT = (TextView) rootView.findViewById(R.id.test);
Bundle test = getArguments();
if(test!=null){
String d = test.getString("test", " ");
TXT.setText(d);
}
return rootView;
}
Hope it helps! :)
