I'm following this tutorial here trying to add fragments to a tabbed Android app but it doesn't accept more than one fragment when I do it.
Also, I'm not sure if I should reference the fully qualified fragment name (e.g. com.mycompany.calcthis.calcfragment) or the short fragment name (e.g. CalcFragment).
What's happening is if I accept the Android Studio red bulb help to refactor the code for adding one of the fragments inside the adapter.addFrag(new fragment name(), "title") clause, it causes the other to be considered an error and it immediately underlines the other one as an error. It only accepts one of the two fragments without error. Weird!
Here's my code:
package thirtyeightdreams.com.calcthis;
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import java.util.ArrayList;
import java.util.List;
public class Calculate extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calculate);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new CalcFragment(), "Calculate");
adapter.addFrag(new TogetherFragment(), "Together");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFrag(PayForFragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
Here's a screen shot of the tip being offered. Notice both fragments are underlined with a red line:
So I accept the tip to refactor the code and it fixes that one:
But then if I accept the same tip code for the line that is still red, the other one that I just fixed becomes red.
So I'm trying to understand how to fix it so I can have multiple fragments listed here.
My overall goal is to have a particular fragment appear when a particular tab is clicked on.
Thanks
Try importing android.support.v4.app.Fragment
Try to import all of your fragments
using android.support.v4.app.Fragment;

Second and Third fragment code is same as mention as Tab 1 code. i just add following code at third Tab code onCreateView method
Toast.makeText(getContext(), "3 fragment", Toast.LENGTH_SHORT).show();
Log.d(TAG, "onCreateView: 3 fragment ");
i am getting following output
as you can show fragment 3 Toast come at second fragment i also notice third fragment log-cat also come at second fragment. i don't know what wrong happen but i notice all time at my current Tab position upcoming Tab Toast and log-cat
show and it will happen at any position at tablayout tab. i am also try other tutorials and other method for create scrollable Tablayout but in all practices i am getting same type of problem. please help me to solve problem i just want my upcoming fragment can't start proceeding until i was visit.at the end sorry for bed formatting i am newbies.
You can check the current selected tab
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser) {
// Show your toast here
}
}
You can use this method to know the currently displayed tab
The FragmentPagerAdapter creates the instance of the next fragment, before it gets used. Part of the lifecycle of the Fragment is called, before the Fragment is attached to the window and is visible.
Some info from Android docs about FragmentPagerAdapter says:
Implementation of PagerAdapter that represents each page as a Fragment that is persistently kept in the fragment manager as long as the user can return to the page.
The fragment of each page the user visits will be kept in memory, though its view hierarchy may be destroyed when not visible.
This is not a sufficient info, but basically it says, that the methods onCreateView() and onDestroyView() are not directly connected with the visibility of the Fragment to the user, so better think about placing your code in onResume() for example or use viewPager.addOnPageChangeListener() to get informed about the changing of pages.
My application is working fine when I use getChildFragmentManager() but unfortunately, it will only work with API 17 and above. Now when I switch it over to getFragmentManager(), everything works fine except for one thing. Whenever I load my tablayout in horizontal view, both pages are empty and swiping is sluggish. Vertically it is fine and they won't be empty if I first load them vertically and then switch to horizontally, because I'm using a saved instance. I have no idea what is causing this. All I know is that as soon as I switch the code above around, it happens. Let me know what is required to find the issue and I will gladly post it. I am using the support-v13 library's FragmentPagerAdapter. I am doing this so I don't have to use support-v4's way of creating fragments. I do import the ViewPager from v4 in my tablayout fragment.
Edit:
Okay when the tablayout is created for the first time, it works fine. When called again it will be blank and sluggish. It had nothing to do with orientation.
Edit:
Tablayout code Keep in mind that this code is functional. But when I change getChildFragmentManager() to getFragmentManager() it gets sluggish and only works on first oncreate:

return rootView;
}
}
Help me please
Like #Mrugesh Thaker says, all of the Fragment lifecycle functions - onCreateView(), etc. are executed every time the View of a Fragment is inflated.
Here, the View of each Fragment is inflated every time it becomes the adjacent Fragment of the current Fragment page.
So, you should move the 'code each Fragment needs to execute' when it becomes the currently selected Fragment page into an OnPageChangeListener
In your HomeTabActivity, when you set up the ViewPager, add an
OnPageChangeListener to yourViewPager
private void setupViewPager(ViewPager viewPager) {
.
.
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener(){
public void onPageScrollStateChanged (int state){
}
public void onPageSelected (int position){
/*
* Define the action to be performed for each page.
* Variable 'position' is the index of the page in the ViewPager
*/
}
public void onPageScrolled (int position, float positionOffset, int positionOffsetPixels){
}
});
}

Actually, view pager works like that. The main aim of view pager is to enable a user to have smooth swipe , so what it does is , it will create all the fragments that you gave at a time to have smooth swiping flow. This is actually the limitation of it because all the methods of fragment lifecycle are called at a time.
I'm following this tutorial: Android Material Design Using Tabs
Infos:
Android API Level 21
Dependecies are added to graddle file
compile 'com.android.support:appcompat-v7:23.0.1' and
compile 'com.android.support:design:23.0.1'
}
The method "findViewById" cannot be resolved. I tried to follow this answer Cannot resolve method 'findViewById(int)' in Fragment, but this AppCompatActivity use OnCreateBundle instead OnCreateView, then i can't get the View object...
What is wrong with this code ? I'm missing some import?

This is the "Error" that Android Studio show but i got 0 erros in logevent window
You appear to be running into the corrupt cache bug in Android Studio.
This happens to me a LOT when adding custom views with a custom namespace. If you added any custom views, this could be your issue.
To fix: File > Invalidate Caches / Restart
That should reindex everything and allow for auto-completion to work, as well, your findViewById() should work. I reviewed the code and do not see any errors.
AppCompatActivity extends FragmentActivity which extends Activity which has findViewById() method.
So it shouldn't be a problem to get the method.
I believe it's IDE bug.
Try to close your IDE and reopen the project.
Worked for me, perfectly.
Update your build tools version to the latest 27.0.3, after trying all solutions this is what worked for me.
in app -> build.gradle
buildToolsVersion '27.0.3'
rebuild and hope it works for you too
I've done some research on this already, and I seem to understand the solutions suggested out there. This is not a repeat question, I'm just having trouble implementing these solutions to my viewpager/fragment code.
So here is my "FirstFragment.java" that sets up my view pager, and the fragment it calls is "UserFragment.java". Basically what I'm doing is providing a user defined number of forms created as pages in my view pager.
I of course, am experiencing the orientation change issue, where fragment gets created a couple times, and eventually lost. I would like to fix it.
My code for FirstFragment.java is:
import java.util.ArrayList;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.util.SparseArray;
public class FirstFragment extends FragmentActivity
{
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_viewpager);
// Check whether the activity is using the layout version with
// the fragment_container FrameLayout. If so, we must add the first fragment
int size = getIntent().getExtras().getInt("numass1");
ViewPager vp = (ViewPager) findViewById(R.id.viewPager);
if (savedInstanceState != null) {
return;
}
ArrayList<Fragment> lf = new ArrayList<Fragment>();
for(int count=0; count<size; count ++){
Fragment f = new UserFragment();
lf.add(f);
}
FragmentAdapter hello = new FragmentAdapter(getSupportFragmentManager() , lf);
vp.setAdapter(hello);
}
SparseArray<Question> questions = new SparseArray<Question>();
public void saveData(Question quest){
ViewPager vp = (ViewPager) findViewById(R.id.viewPager);
questions.put(vp.getCurrentItem(), quest);
}
public ViewPager getPager() {
ViewPager vp = (ViewPager) findViewById(R.id.viewPager);
return vp;
}
}
Just incase, my FragmentAdapter.java code is:
import java.util.ArrayList;
import java.util.List;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.view.ViewGroup;
public class FragmentAdapter extends FragmentPagerAdapter{
private List<Fragment> fragments;
public FragmentAdapter(FragmentManager fragmentManager, ArrayList<Fragment> fragments) {
super(fragmentManager);
this.fragments = fragments;
}
#Override
public Fragment getItem(int position) {
Fragment fragment = fragments.get(position);
Bundle args = new Bundle();
args.putInt("page_position", position + 1);
args.putInt("size", fragments.size());
fragment.setArguments(args);
return fragment;
}
#Override
public void destroyItem (ViewGroup container, int position, Object object)
{
super.destroyItem(container, position, object);
}
#Override
public int getCount() {
return this.fragments.size();
}
}
Please keep in mind, I am clearly a noob, and I'm trying to learn. So code snippets, and explanations would be awesome!
Thank you very much for your time and help.
EDIT: Please help ...
If you add
android:configChanges="orientation|keyboardHidden"
in <activity> node of your file AndroidManifest.xml your activity will not reset when the orientation changed.
Is it what you wanted?
