On tab, I have attached five fragments.Till 3rd fragment navigation is fine but when going to 4th and 5th fragment directly or by swiping, app is getting crashed.
This is my main activity.

This is my fragment class which is right now same for all the five fragments except the class name).

ClickMe.setOnClickListener(new View.OnClickListener() {

});
return rootView;

} // This is the end of our MyFragments Class
Case 4 is missing in your adapter. Add the Case 4 instead of 5 then it will work fine.

I have on activity (MainActivity) and it has five tabs, each tab contains a fragment. Each fragment contains an EditText widget. I'd like to set the active tab's title when I change the text of the EditText in the active fragment's class. How could I do that on the fly ?
Here are my resources:
MainActivity:
public class MainActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
ImageView imageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
#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);
}
}
SectionPagerAdapter:
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0:
Tab1 tab1 = new Tab1();
return tab1;
case 1:
Tab2 tab2 = new Tab2();
return tab2;
case 2:
Tab3 tab3 = new Tab3();
return tab3;
case 3:
Tab4 tab4 = new Tab4();
return tab4;
case 4:
Tab5 tab5 = new Tab5();
return tab5;
default:
return null;
}
}
#Override
public int getCount() {
// Show 5 total pages.
return 5;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "title1";
case 1:
return "title2";
case 2:
return "title3";
case 3:
return "title4";
case 4:
return "title5";
}
return null;
}
}
Tab1:
public class Tab1 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab1, container, false);
return rootView;
}
}
These are generated by Android Studio, so I guess I should go from here. What I want, if I have an EditText on the Tab1, and I start to type in it, it changes the first tab's title from "title1" to the string I typed.
From edittext you should use addTextChangedListener on EditText within that TextWatcher instance to change title on the fly. Refer this code.
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
//this is your tab index you want to change title of..
tabLayout.getTabAt(1).setText(charSequence);
}
#Override
public void afterTextChanged(Editable editable) {
}
});
Hope this helps..
I have 6 Fragments within an activity that I created as
I want to swipe from one to the other and need them to not being dismissed but onyl hide/show y the viewpager.
Is there a way to derive a viewpager class or a SectionsPagerAdapter to do that.
I already add
mViewPager.setOffscreenPageLimit(6);
but it didn't work. When swiping from the 4th fragment to 3rd or to 5th, the app crashes.
Relevant parts of my code simpified and renamed Fragment classes to get the code readable:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// create the fragment once for all !
if (savedInstanceState == null) {
fragment1 = Fragment1.newInstance(1);
fragment2 = Fragment2.newInstance(2);
fragment3 = Fragment3.newInstance(3);
fragment4 = Fragment4.newInstance(4);
fragment5 = Fragment5.newInstance(5);
fragment6 = Fragment6.newInstance(6);
}
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.setOffscreenPageLimit(6);
});
public static class Fragment1 extends Fragment {
private static final String ARG_SECTION_NUMBER = "section_number";
public Fragment1() {
}
public static Fragment1 newInstance(int sectionNumber) {
Fragment1fragment = new Fragment1();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
fragment.setRetainInstance( true);
return fragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_1, container, false);
TextView textView = (TextView) rootView.findViewById(R.id.section_label);
// "Main Frag"
textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
return rootView;
}
#Override
public void onResume() {
super.onResume();
// The activity is about to become visible again, recalcule
}
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
// Return a PlaceholderFragment (defined as a static inner class below).
//return PlaceholderFragment.newInstance(position + 1);
switch (position)
{
case 0 : return fragment1; //instead of Fragment1.newInstance(1);
case 1 : return fragment2;
case 2 : return fragment3;
case 3 : return fragment4;
case 4 : return fragment5;
case 5 : return fragment6;
default: return null;
}
}
#Override
public int getCount() {
// Show 6 total pages.
return 6;
}

Extend your section pager adapter by FragmentSatePagerAdaper
And set
mViewPager.setOffscreenPageLimit(6);
I'm developing an application in which I have to implement a function that allows to me to change a Fragment with a Button instead of crawling the site on the screen.

Button next = (Button) rootView.findViewById(R.id.next);
Button previous = (Button) rootView.findViewById(R.id.previous);
RelativeLayout rl = (RelativeLayout) rootView.findViewById(R.id.relative_tutorial);
switch (getArguments().getInt(ARG_SECTION_NUMBER)){
case 1:
rl.setBackgroundResource(R.drawable.one);
previous.setText("ESCI");
previous.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
getActivity().finish();
}

next.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
});
break;
case 2:
rl.setBackgroundResource(R.drawable.two);
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
}
});
break;
case 3:
rl.setBackgroundResource(R.drawable.three);
next.setText("HOME");
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

How I can switch "page" by clicking my Button, instead of crawling the site on the screen?
This is how you display another fragment. So, just put this code inside your buttons onclick method.
Example:
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(android.R.id.content, new Fragment_1(), "frag1");
fragmentTransaction.commit();
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.

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));

There are 2 problems with your code:
The final View v in the onCreateView is shadowed by the View v being passed as an argument of the onClick method.
You need to setup pager before you can use it. At present, you are setting it up in the onClick method. You need to move the pager setup code to the onCreateView method.
