How to show/hide a static fragment in Android

I know there are a bunch of answers on StackOverflow regard my question but none of them fixed my problem as my Fragments are static.
I have two fragments in my activity. The second one is covering the first one and this is the fragment that will be shown/hidden.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".FeedActivity">
<fragment
android:id="#+id/listViewFragment"
android:layout_width="0dp"
android:layout_height="0dp"
android:name="com.me.cscomponents.fragFeed.FeedFragment"
tools:layout="#layout/fragment_feed"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/gh1"
app:layout_constraintBottom_toBottomOf="parent"/>
<fragment
android:id="#+id/playerViewFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.me.cscomponents.fragPlayer.PlayerFragment"
tools:layout="#layout/fragment_player"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/gh1"
app:layout_constraintBottom_toBottomOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
In the TV app, both of Fragments are visible side by side. However, in the mobile app, listViewFragment is visible by default and playerViewFragment displays when an item in listViewFragment clicks by the user. When the user clicks on the Back button then this view becomes hidden (and therefore listViewFragment becomes visible).
This is my code (but it doesn't work as I expect):
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_feed)
listFragment = supportFragmentManager.findFragmentById(R.id.listViewFragment) as FeedFragment
playerFragment = supportFragmentManager.findFragmentById(R.id.playerViewFragment) as PlayerFragment
val d1: Disposable = listFragment.onClickSubject
.subscribe {
showOrHidePlayerFragment(true)
playerFragment.streamCamera(it.camFeedUrl)
}
cd.add(d1)
showOrHidePlayerFragment(false)
}
private fun showOrHidePlayerFragment(isVisible: Boolean) {
val fm = supportFragmentManager.beginTransaction()
if (isVisible) fm.show(playerFragment) else fm.hide(playerFragment)
fm.commit()
}
The problem is playerFragment is still visible when I launch the activity. So, I have no idea how to fix the issue and what is the cause of the problem.
My current workaround is to surround my playerFragment in a FrameLayout and make this view visible/invisible. This approach works fine.

I think few stuff went wrong with your coding. Try to avoid hard coding fragment like
android:name="com.me.cscomponents.fragFeed.FeedFragment"
Based on your question i prepared a something for you. I just implemented two button click rather publishing a list. Passed an int (you can pass according to your need.). I tried to follow few best practices. For simplicity i used LinearLayout & RelativeLayout.

Hope it will help you. Thanks.

The tag fragment has an id, the Fragment root view will have that id.
So it will be
findViewById(R.id.oneFragment).setVisibility(View.GONE);
By example, if FragmentOne use the following layout:
<LinearLayout>
<!--Chile Viiews-->
</LinearLayout>
And you are using the tag fragment, like this:
<fragment
id=oneFragment
name=FragmentOne/>
Then that linear layout will end up having oneFragment as id. That is how the tag fragment works after the fragment is attached the tag fragment id is assigned to the root view o the fragment. You can read more here.
Another way to do this is to use the fragment manager, here is a one-liner:
getSupportFragmentManager().findFragmentById(R.id.fragment).getView().setVisibility(View.GONE);

ViewPager not showing up in xml and not working in emulator?

I have an application where I have a part of the screen for displaying information about a student and the remaining part with tablayout and viewpager. My problem is tablayout shows up in the design editor but viewpager doesn't. In-spite of the code written nothing is showing up. Tell me where I am getting things wrong?

In the emulator viewpager doesn't showup and tablayout remain untouchable.What I am getting wrong here. Help me to proceed further. Thanks in advance.
Emulator Output

Many things are wrong in the code.
in xml : add android:layout_height="match_parent" for viewpager
<android.support.v4.view.ViewPager
android:id="#+id/viewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/tabLayout"
android:layout_centerHorizontal="true">
in code:
change your code as: you need to use fragment's view to get the viewpager instance. Also your code missing some basic functionalities for viewpager with tablayout
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_camarks, container, false);
viewPager=(ViewPager)view.findViewById(R.id.viewPager);
tabLayout=(TabLayout)view.findViewById(R.id.tabLayout);
tabLayout.addTab(tabLayout.newTab().setText("Theory"));
tabLayout.addTab(tabLayout.newTab().setText("Practical"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
viewPager.setAdapter(new CustomAdapter(getActivity().getSupportFragmentManager(),getActivity().getApplicationContext()));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
tabLayout.setupWithViewPager(viewPager);
return view;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//you can set the title for your toolbar here for different fragments different titles
getActivity().setTitle("CA Marks");
}

It could be because you are using views from androidx
Well it does have ViewPager along with ViewPager2
Add the following line in build.gradle(:app) file:
implementation 'androidx.viewpager:viewpager:1.0.0'

Android : Activity button shows up on fragment

I have a simple application, with an Activity calling a Fragment.
Question I have is .. why is the Activity's button showing up on the Fragment ?
Seems to be a very simple problem .. just not able to pin point the issue !!

Notice that Activity's SUBMIT button shows up on the Fragment, but the TextView and EditText get hidden. Why ??

I've solved this by wrapping my button inside a LinearLayout.
Probable cause of the issue: It seems Button has higher z-index rendering when it comes to android and thus not wrapping it inside another layout renders the button higher than all other fragments.
<LinearLayout
android:id="#+id/register_btn_wrapper"
android:orientation="vertical"
android:layout_below="#+id/splash_logo_img"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/register_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/register"
android:textSize="#dimen/text_big"
android:paddingLeft="#dimen/btn_padding"
android:paddingStart="#dimen/btn_padding"
android:paddingRight="#dimen/btn_padding"
android:paddingEnd="#dimen/btn_padding"
android:layout_gravity="center"
android:background="#color/app_color" />
</LinearLayout>
Hope this helps.

When you bind your view in fragment it is always a better approach to bind it in the method
onViewCreated()
When you bind your view in onCreateView() you will face rendering issues.
So bind your view in onViewCreated() method and the problem should be solved
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.name_of_layout,container,false);
}
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//bind your view here
}

In the onCreateView of the fragment try adding this line
View view = inflater.inflate(R.layout.fragment_name, container, false);
view.setBackgroundColor(Color.WHITE);
I had a similar issue and fixed it using the above lines. Also, don't forget to add android:clickable="true" to your fragment_layout.xml parent layout.

I couldn't find the reason for this issue though but here is a small workaround:
Update the below layouts and try:
Activity xml :
Added a Framelayout:
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include layout="#layout/content_main"/>
</FrameLayout>
And in MainActivity: Used Framelayout container
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
CreateReportFragment fragment = CreateReportFragment.newInstance();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(**R.id.container**, fragment, "CreateFragment");
transaction.addToBackStack("CreateBackStack");
transaction.commit();
}
});
In Content.xml Added android:layout_marginTop
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_marginTop="?attr/actionBarSize"
tools:context="com.example.deep_kulshreshtha.toddsyndrome.MainActivity"
tools:showIn="#layout/activity_main">
In fragment_create_report.xml added android:layout_marginTop
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"
android:background="#android:color/white">

I'm not sure if you still need help with this. But basically the fragment and the activity have to be in different layouts.
This is the general structure for it: (you don't have to use the specific layouts I user below)
<RelativeLayout>
<LinearLayout id="#+id/all_code_relevant_to_activity"></LinearLayout>
<LinearLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
</LinearLayout>
</RelativeLayout>
Basically you want to have your fragment separate from the rest of the code. So basically you could make a <FrameLayout> around your code in Activity.xml and then add your fragment layout by itself inside the <FrameLayout> but outside <android.support.design.widget.CoordinatorLayout>. Or make two sub layouts the split them apart

It's so wired to show only SUBMIT button on the top of page. I want to suggest you to add fragment instead of replace. please let me know the result after this.
FragmentTransaction fragmentTransaction = activity.getSupportFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.content_main, fragment, "SearchFragment");
fragmentTransaction.addToBackStack("SearchFragment");
fragmentTransaction.commitAllowingStateLoss();

In your activity xml, add one more element, FrameLayout to host the fragment, like below
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.example.deep_kulshreshtha.toddsyndrome.MainActivity"
tools:showIn="#layout/activity_main">
<TextView
android:id="#+id/headline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:textSize="32dp"
android:fontFamily="cursive"
android:text="#string/todd_syndrome" />
<!-- <android.support.design.widget.TextInputLayout
android:id="#+id/layout_last_name"
android:layout_below="#id/headline"
android:layout_centerHorizontal="true"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TextInputEditText
android:id="#+id/lastNameEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/edit_text_hint" />
</android.support.design.widget.TextInputLayout>-->
<EditText
android:id="#+id/editText"
android:layout_below="#id/headline"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/edit_text_hint"/>
<Button
android:id="#+id/submitButton"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/submit"
android:layout_below="#id/editText"
android:onClick="viewPatientReport"/>
<!-- new layout to host fragment -->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_holder"/>
</RelativeLayout>
and add your Fragment to that FrameLayout using.

set button property android:translationZ="-3dp" it will work.

What helped me is to add android:translationZ="10dp" to the layout that above the Buttons

Cannot use custom ListView layout

I am trying to create a custom ListView but i can not even compile it, since it gives me this error early on:
Error:(25, 63) error: cannot find symbol variable listing
where "listing" is the xml file name for my ListView layout.
What am i doing wrong?
This is my fragment code:
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;
public class ListingFragment extends Fragment {
private CustomcursorAdapter mCustomcursorAdapter;
private ListView mListView;
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_listing, container, false);
//CursorAdapter
mCustomcursorAdapter = new CustomcursorAdapter(view.getContext(), null, 0);
//ListView
mListView = (ListView) view.findViewById(R.id.listing);
mListView.setAdapter(mCustomcursorAdapter);
return view;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
}
fragment_listing
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
</RelativeLayout>
MainActivity and activity_main
import android.app.Activity;
import android.app.FragmentManager;
import android.os.Bundle;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fragmentManager = getFragmentManager();
if (fragmentManager.findFragmentById(android.R.id.content) == null) {
Listing listing = new Listing();
fragmentManager.beginTransaction().add(android.R.id.content, listing).commit();
}
}
}
activity_main
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}">
<TextView
android:text="#string/hello_world"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>

In your fragment_listing.xml you should add:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/listing"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:cacheColorHint="#android:color/transparent" >
</ListView>
</RelativeLayout>
It didnt compile because you didnt have that id in R.java
Edit
In your activty_main xml add:
<FrameLayout
android:id="#+id/fragmentContainer"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
Then in your MainActivity add:
FragmentTransaction transaction = getFragmentManager().beginTransaction();
Fragment fragment = new Listing();
transaction.replace(R.id.fragmentContainer,fragment);
ft.addToBackStack(null);
ft.commit();

call fragment issue in button onclick

I create a fragment extend class to call layout as following
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_centerVertical="true"
android:layout_marginLeft="200dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="32dp"
android:textStyle="bold"
android:text="time_label"
/>
<TextView
android:id="#+id/last_view_time"
android:layout_toRightOf="#+id/date_time_label"
android:layout_alignBaseline="#+id/date_time_label"
android:layout_marginLeft="8dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="32dp"
/>
</LinearLayout>
package com.appnetics;
import java.text.SimpleDateFormat;
import java.util.Date;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
/**
* DateTime
*/
public class details extends Fragment {
private static String getDateTimeString(Date time) {
return new SimpleDateFormat("d MMM yyyy HH:mm:ss")
.format(time);
}
private final String time = getDateTimeString(new Date());
/** #see android.app.Fragment#onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle) */
#Override
public View onCreateView(
LayoutInflater inflater,
ViewGroup container,
Bundle b)
{
View view = inflater.inflate(
R.layout.details,
container,
false); //!!! this is important
((TextView) view.findViewById(R.id.last_view_time))
.setText(time);
return view;
}
}
now to use it I create layout like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<Button
android:id="#+id/btn_showdetails"
android:layout_width="100dip"
android:layout_height="wrap_content"
android:layout_marginLeft="110dip"
android:layout_marginTop="15dip"
android:text="Show Details" />
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:id="#+id/my_parent_layout"
>
</LinearLayout>
</LinearLayout>
on the click event of the button I say
setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
details fragment = new details();
fragmentTransaction.add(R.id.my_parent_layout, fragment);
fragmentTransaction.commit();
}
});
but it raise error
The method getFragmentManager() is undefined for the type new View.OnClickListener(){}
any idea how to solve that

if call activity from fragment then code below or call fragment to fragment then simply replace the code instead of startactivity onclick method
public class FragmentA extends Fragment implements OnClickListener{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_start, container, false);
Button button1 = (Button) v.findViewById(R.id.StartButton);
button1.setOnClickListener(this);
return v;
}
#Override
public void onClick(View v) {
startActivity(new Intent(getActivity(),testing.class));
}
}
}

Declare and set the fragmentManager as final, before the listener definition.
final FragmentManager fragmentManager = getFragmentManager();
<your listener declaration>
you should be able to use it in the listener.

Below code works
Button publishButton =(Button)
fragmentView.findViewById(R.id.publishButton);
publishButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
publish();
}
});
