Cannot resolve constructor Intent

Im trying to add a tabhost to my application but i cant figure why this error 'cannot resolve constructor intent' is showing, here's my activity code:
public class SixthFragment extends Fragment {
public static final String TAG = "sixth";
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.sixthfragment, container, false);
TabHost tabHost = (TabHost) view.findViewById(R.id.tabHost);
TabHost.TabSpec tab1 = tabHost.newTabSpec("First Tab");
TabHost.TabSpec tab2 = tabHost.newTabSpec("Second Tab");
TabHost.TabSpec tab3 = tabHost.newTabSpec("Third tab");
// Set the Tab name and Activity
// that will be opened when particular Tab will be selected
tab1.setIndicator("Tab1");
tab1.setContent(new Intent(this,MainActivity.class));
tab2.setIndicator("Tab2");
tab2.setContent(new Intent(this,Tab2Activity.class));
tab3.setIndicator("Tab3");
tab3.setContent(new Intent(this,Tab3Activity.class));
/** Add the tabs to the TabHost to display. */
tabHost.addTab(tab1);
tabHost.addTab(tab2);
tabHost.addTab(tab3);
return view;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
}
some help would be apreciated, thanks for your time.

The first parameter to the Intent constructor that you are trying to use takes a Context. Fragment is not a Context. Use getActivity() instead of this.

Detecting event on a FragmentTabHost present in Fragment

What I have:
I have a fragment
I am using SherlockActionBar library
I have a FragmentTabHost in Fragment
What i want to know: I want to detect onClick event each tab and perform some action based on it
Fragment1.java:
public class Fragment1 extends SherlockFragment{
private FragmentTabHost mTabHost;
//Mandatory Constructor
public Fragment1() {
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment1,container, false);
mTabHost = (FragmentTabHost)rootView.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("fragmentb").setIndicator("Rating"),
RatingAscending.class, null);
mTabHost.addTab(mTabHost.newTabSpec("fragmentc").setIndicator("Price"),
PriceAscending.class, null);
mTabHost.addTab(mTabHost.newTabSpec("fragmentd").setIndicator("Distance"),
DistanceAscending.class, null);
return rootView;
}
}

I'm assuming what you want to do is detect when a specific tab has been clicked in your FragmentTabHost. This can be accomplished quite simply by adding a setOnTabChangedListener.
Here is an example:
FragmentTabHost t = new FragmentTabHost(getActivity());
t.setOnTabChangedListener(new OnTabChangeListener() {
#Override
public void onTabChanged(String tabId) {
// TODO your actions go here
}
});
}

How to add Run Time Tabs into TabHost in Android?

Hello I am developing an application
Which requires to add Run Time tabs in the android And all the tabs should add dynamically.
My Requirement is:
I want to add Tabhost with 5 tabs Which Should display the Screen.
But some Time it require only 3 tabs in the screen then design should not change.
Same if I want to add more then 5 tabs then tab should scroll Run time The main Thing is Design should not change.
Can any one tell me How can i do that?
Currently I am using Following Code:
public class Story_List extends ActivityGroup
{
ListView list_stories;
TabHost tab_stories;
#SuppressWarnings("deprecation")
#Override
protected void onCreate(Bundle savedInstanceState)
{
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.story_list);
tab_stories=(TabHost)findViewById(R.id.tabhoststories);
tab_stories.setup(this.getLocalActivityManager());
setupTab1(new TextView(this), "Album 1");
setupTab2(new TextView(this), "Album 2");
setupTab3(new TextView(this), "Album 3");
}
private void setupTab1(final View view, final String tag)
{
View tabview = createTabView(tab_stories.getContext(), tag);
Intent intent = new Intent().setClass(this, StoryAlbum1.class);
TabSpec tab = tab_stories.newTabSpec(tag).setIndicator(tabview).setContent(intent);
tab_stories.addTab(tab);
}
private void setupTab2(final View view, final String tag)
{
View tabview = createTabView(tab_stories.getContext(), tag);
Intent intent = new Intent().setClass(this, StoryAlbum2.class);
TabSpec tab = tab_stories.newTabSpec(tag).setIndicator(tabview).setContent(intent);
tab_stories.addTab(tab);
}
private void setupTab3(final View view, final String tag)
{
View tabview = createTabView(tab_stories.getContext(), tag);
Intent intent = new Intent().setClass(this, StoryAlbum3.class);
TabSpec tab = tab_stories.newTabSpec(tag).setIndicator(tabview).setContent(intent);
tab_stories.addTab(tab);
}
private static View createTabView(final Context context, final String text)
{
View view = LayoutInflater.from(context).inflate(R.layout.tabs_text, null);
TextView tv = (TextView) view.findViewById(R.id.tabsText);
tv.setText(text);
return view;
}
}

try this :
TabHost.TabSpec tabSpec = tabHost.newTabSpec("Tab1");
tabSpec.setContent(R.id.btnTab);
tabSpec.setIndicator("My Tab 1");
tabHost.addTab(tabSpec);
btnAddTab.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
TabHost.TabSpec spec = tabHost.newTabSpec("Tab"+i);
spec.setContent(new TabHost.TabContentFactory() {
#Override
public View createTabContent(String tag) {
return new AnalogClock(MainActivity.this);
}
});
spec.setIndicator("Clock");
tabHost.addTab(spec);
}
});

FragmentTabHost not creating view inside Fragment in android

I am having an issue getting the view to change on a tabhost - when I select a tab the content stays blank.
From what I can tell, onCreateView is not being called on the child Fragments. onMenuCreate runs fine because the menu changes like it is supposed to.
public class PatientTabFragment extends Fragment {
private FragmentTabHost mTabHost;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mTabHost = new FragmentTabHost(getActivity());
mTabHost.setup(getActivity(), getChildFragmentManager());
mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Info"),
NewPatientFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("contacts").setIndicator("Notes"),
NoteListFragment.class, null);
return mTabHost;
}
#Override
public void onDestroyView() {
super.onDestroyView();
mTabHost = null;
}
}

according to the docs:
Special TabHost that allows the use of Fragment objects for its tab
content. When placing this in a view hierarchy, after inflating the
hierarchy you must call setup(Context, FragmentManager, int) to
complete the initialization of the tab host.
(emphasis mine)
So I suggest somethong like this:
public class PatientTabFragment extends Fragment {
private FragmentTabHost mTabHost;
private boolean createdTab = false;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mTabHost = new FragmentTabHost(getActivity());
mTabHost.setup(getActivity(), getChildFragmentManager());
mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Info"),
NewPatientFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("contacts").setIndicator("Notes"),
NoteListFragment.class, null);
return mTabHost;
}
public void onResume(){
if (!createdTab){
createdTab = true;
mTabHost.setup(getActivity(), getActivity().
getSupportedFragmentManager());
}
}
#Override
public void onDestroyView() {
super.onDestroyView();
mTabHost = null;
}
}

Now we can use TabLayout and ViewPager do those things.This is a good guide to use it.Here is my code:
viewPager=(NonSwipeableViewPager)view.findViewById(R.id.circleresdyn_viewpager);
tabLayout=(TabLayout)view.findViewById(R.id.circleresdyn_tablayout);
if (viewPager != null) {
Adapter adapter = new Adapter(((AppCompatActivity)activity).getSupportFragmentManager());
ContentFragment con=new ContentFragment();
con.setArguments(bundleForFramgnet);
MemberFragment memberFragment=new MemberFragment();
memberFragment.setArguments(bundleForFramgnet);
CirResDynTileFragment cirResDynTileFragment=new CirResDynTileFragment();
cirResDynTileFragment.setArguments(bundleForFramgnet);
adapter.addFragment(cirResDynTileFragment, "Tab1");
adapter.addFragment(con, "Tab2");
adapter.addFragment(memberFragment, "Tab3");
viewPager.setAdapter(adapter);
viewPager.setOffscreenPageLimit(3);
tabLayout.setTabGravity(TabLayout.GRAVITY_CENTER);
tabLayout.setupWithViewPager(viewPager);
tabLayout.getTabAt(0).select();
}

Check this peace of code. It may help you:
import android.app.Fragment;
public class Change_password extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.change_password, container,false);
setTabs();
return rootView;
}
private void setTabs() {
try {
addTab("Airlines", R.drawable.tab_home, HomeActivity_bkp.class);
addTab("Advance Search", R.drawable.tab_search,
AdvanceSearchAcitivty.class);
addTab("Booking", R.drawable.tab_home, Booking.class);
addTab("Settings", R.drawable.tab_search, SettingAcitivty.class);
} catch (Exception e) {
Toast.makeText(getApplicationContext(), e.toString(),
Toast.LENGTH_LONG).show();
// TODO: handle exception
}
}
private void addTab(String labelId, int drawableId, Class<?> c) {
TabHost tabHost = getTabHost();
Intent intent = new Intent(this, c);
TabHost.TabSpec spec = tabHost.newTabSpec("tab" + labelId);
View tabIndicator = LayoutInflater.from(this).inflate(
R.layout.tab_indicator, getTabWidget(), false);
TextView title = (TextView) tabIndicator.findViewById(R.id.title);
title.setText(labelId);
ImageView icon = (ImageView) tabIndicator.findViewById(R.id.icon);
icon.setImageResource(drawableId);
spec.setIndicator(tabIndicator);
spec.setContent(intent);
tabHost.addTab(spec);
}

actionbarsherlock with multiple fragments under a single tab

I created my Sherlock fragment activity and implemented tabs:
public class Home extends SherlockFragmentActivity
{
ActionBar actionBar;
TabHost myTabHost;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
actionBar=getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab tab1= actionBar.newTab();
ActionBar.Tab tab2= actionBar.newTab();
//ActionBar.Tab tab3 = actionBar.newTab();
tab1.setText("Contacts");
tab2.setText("Inbox");
// tab3.setText("Outbox");
tab1.setTabListener(new MyTabListener());
tab2.setTabListener(new MyTabListener());
actionBar.addTab(tab1, true);
actionBar.addTab(tab2);
actionBar.addTab(tab3);
}
And this is my tab change listener:
private class MyTabListener implements TabListener
{
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if(tab.getPosition()==0)
{
FragmentA frag = new FragmentA ();
ft.replace(android.R.id.content, frag );
}
else
{
FragmentB frag = new FragmentB ();
ft.replace(android.R.id.content,frag );
}
}
And this is my FragmentA:
public class FragmentA extends Fragment
{
TextView textView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
return inflater.inflate(R.layout.activity_list, container, false);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
}
}
Here under my first tab, there is a list that is displaying. When I click any one of the list items, I need to load another fragment under the same activity. And when back is pressed, the old fragment needs to be loaded under the same tab.
Is this possible in actionbarsherlock tabs? If so, how do I do this?
