How can I hide the fab on the other tabs and only show it on the first tab? I'm using the GET_ARGUMENTS to select between activities. Help please. Here is my code. Thanks.
public class OwnerTabs extends AppCompatActivity {

if(id == R.id.action_logout){
editor = pref.edit();
editor.clear();
editor.commit();
Intent in = new Intent (getApplicationContext(), MainActivity.class);
startActivity(in);
finish();
}
return super.onOptionsItemSelected(item);

Thanks for the help guys, hoping to get a kind response and not an arrogant one. :)
Add a on tab selected listener, and then put on the tab index you want, and call fab.hide()

I have a Problem with launching an Activity from Fragment.
My Application is built like a tab layout with an Activity in the background and fragment with the tabs. In one of this tabs I want to set a Button, this Button has to launch the Activity. I tried everything but I'm wondering why it's not working.
The Logcat also shows nothing.
This is the Fragment with the Button
public class Freestyle extends Fragment {
public Freestyle() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_freestyle, container, false);
Button btnOpen;
btnOpen =(Button)view.findViewById(R.id.btnOpenPlan);
btnOpen.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent(getContext(),Plan.class);
startActivity(intent);
}
});
return view;
}
}
This is the Code from the Activity, which has to be launched
public class Plan extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_plan);
}
}
This is the Code from the Background Activity
public class MainActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container2);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public static class PlaceholderFragment extends Fragment {
private static final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment() {
}
public static PlaceholderFragment newInstance(int sectionNumber) {
PlaceholderFragment fragment = new PlaceholderFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = null;
switch (getArguments().getInt(ARG_SECTION_NUMBER)) {
case 1:
//eine Serververbindung
rootView = inflater.inflate(R.layout.fragment_freestyle, container, false);
break;
case 2:
//eine weitere
rootView = inflater.inflate(R.layout.fragment_events, container, false);
break;
case 3:
//eine weitere
rootView = inflater.inflate(R.layout.fragment_map, container, false);
break;
case 4:
//eine weitere
rootView = inflater.inflate(R.layout.fragment_tipp, container, false);
break;
case 5:
//eine weitere
rootView = inflater.inflate(R.layout.fragment_person, container, false);
break;
}
return rootView;
}
}
public static class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
return PlaceholderFragment.newInstance(position + 1);
}
#Override
public int getCount() {
return 5;
}
}
Use this,
btnOpen.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getActivity(), Plan.class);
getActivity().startActivity(intent);
}
});
Try this
Intent intent=new Intent(getActivity(),Plan.class);
getActivity().startActivity(intent);
Try using the getActivity(type casted to your Activity instance) to start new Activity from fragment
btn1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(((MainActivity) getActivity()), Plan.class);
((MainActivity) getActivity()).startActivity(intent);
}
});
Hope this helps.
Try something like this
btnLaunchActivity.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Check if getActivity() is actually not null, could be null if fragment detatched, you could also check if its an instance you expect to be
if(getActivity() != null && getActivity() instanceof MyActivity) {
Intent intent = new Intent(getActivity(), TargetActivity.class);
//Launch the intent from the activity reference
getActivity().startActivity(intent);
}
}
});

Thank you for the help
Try giving this in Android manifest file
android:screenOrientation="portrait"
You must save text content , because when rotation screen ,your activity will reset life cycle of android, same as first open.
See how to save the status here: Losing data when rotate screen

Case 4 is missing in your adapter. Add the Case 4 instead of 5 then it will work fine.
I'm hoping someone can help me with this extremely annoying problem. I'm new to working with fragments. I've have spend two days trying to get buttons to work inside my fragment. My app is a tab activity with sliding fragments auto created by android studio. I can change fragments by sliding and using the tabs. But I cannot get the buttons to respond. My app does not crash and my Log.e doesn't get registered in Logcat. I have copied lots of examples from the internet, but nothing seems to work.
I have tried implementing View.OnClickListener and not implementing it but nothing works. I'll post two examples that should work, but they don't.
FRAGMENT without implementing View.OnClickListener
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_summary_loggs, container, false);
Button test = (Button) rootView.findViewById(R.id.testButton);
test.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.e("DEBUGG", "BUTTON PRESSED");
}
});
return rootView;
FRAGMENT with implementing View.OnClickListener
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_summary_loggs, container, false);
Button test = (Button) rootView.findViewById(R.id.testButton);
test.setOnClickListener(this);
return rootView;
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.testButton:
Log.e("DEBUGG", "BUTTON PRESSED");
break;
}
}
This is only two examples of many that I have tried and it is driving me crazy. On all the examples on internet they all get them to work. My buttons simply won't respond when I press them. I will be extremely thankful if you could help me with this.

I think you're not creating 3 fragments. You should have 3 fragment classes in your activity one for each tab and also depending upon design for each fragment, you need to have 3 layout files. Then declare the button in your appropriate layout file and use it in your Fragment class as shown below.
public class AmLogger extends ActionBarActivity implements ActionBar.TabListener {
SectionsPagerAdapter mSectionsPagerAdapter;
Handler customHandler = new Handler();
ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_am_logger);
final ActionBar actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
actionBar.addTab(
actionBar.newTab()
.setText(mSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this));
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_am_logger, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;

return super.onOptionsItemSelected(item);
