How to replace and open a fragment from another fragment in android by the click of a button?

I am unable to remove a present fragment in my second fragment while trying to replace it from the first fragment along with trying to open the second fragment from the first fragment on a click of a button.
Here is my code
FirstFragment.java

Button enterButton;
String getMessage;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.first_fragment,container,false);
inputEditText = view.findViewById(R.id.enter_edit_txt_input);
enterButton = view.findViewById(R.id.first_fragment_btn);
enterButton.setOnClickListener(this);
return view;
}
#RequiresApi(api = Build.VERSION_CODES.KITKAT)
#Override
public void onClick(View v) {
getMessage = inputEditText.getText().toString();
SecondFragment secondFragment = new SecondFragment();
Bundle b = new Bundle();
b.putString("data",getMessage);
secondFragment.setArguments(b);
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.second_fragment_layout,secondFragment);
//transaction.add(R.id.second_fragment_layout,secondFragment);
transaction.commit();
***Below here I am trying to change the code
***In order to open the second fragment from the first fragment
/assert getFragmentManager() != null;
FragmentManager fm = getFragmentManager();
fm.beginTransaction().replace(R.id.second_fragment_layout,secondFragment).commit();/
//fm.beginTransaction().replace(SecondFragment.newInstance());
}
}

and to open the second fragment from the first fragment on a click of a button
first make mainViewPager static
static ViewPager mainViewPager
put this on first fragment onclick
int page =1;
mainViewPager.setCurrentItem(page);
to back to first fragment
put this on second fragment onclick
int page =0;
mainViewPager.setCurrentItem(page);
ts working for me.!

Creating multiple button counters in ListView in TabActivity

I'm trying to make an app to keep score during a game of golf. To do this I have 18 tabs in a tab activity (one for each hole) and then in each tab I have a ListView with a list of players, their score for the hole, and a plus and minus button.
I need to make it so that hitting the plus button in a row increases that players score for that hole but I'm having trouble figuring out where and how to do an OnClickListener and how to handle the indexing for the player and the hole.
I'm very new to Android Studio so any help is greatly appreciated!

How to make multiple layout for one screen?
my approach for this goal is using Fragments
how?
i do make a single main_layout and set a FrameLayout in order to put fragments with different layouts.so i have a screen with different layouts.
this is my best answer for your question .

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 !!
Activity screenshot :
Fragment Screenshot :
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

Trouble with fragments and adapter

I'm working on a little app which is supposed to display 3 screens : Talks, Papers and Choices. I've discovered fragments a few days ago and I would like to use this feature for my app, but unfortunately, it doesn't work for a particular reason…
My fragment:
package info.androidhive.tabsswipe;
import java.io.IOException;
import java.util.List;
import be.unamur.confpers.beans.Paper;
import be.unamur.confpers.xml.XMLParser2;
import info.androidhive.tabsswipe.R;
import info.androidhive.tabsswipe.adapter.PaperAdapter;
import android.app.ListFragment;
import android.content.Context;
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.ListView;
import be.unamur.confpers.beans.Paper;
import be.unamur.confpers.xml.XMLParser2;
import be.unamur.confpers.*;
public class PapersFragment extends Fragment {
private PaperAdapter listAdapter;
private Context myContext;
List<Paper> papers = null;
private List<Paper> papersParser () {
try {
XMLParser2 parser = new XMLParser2();
papers = parser.parse(getActivity().getApplicationContext().getAssets().open("talks.xml"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return papers;
};
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_papers, container, false);
ListView lv = (ListView) getActivity().findViewById(R.id.check1);
listAdapter = new PaperAdapter(getActivity(),papers);
//lv.setAdapter(listAdapter);
return v;
}
}
My adapter :
package info.androidhive.tabsswipe.adapter;
import android.content.Context;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;

import android.widget.CheckBox;
import be.unamur.confpers.beans.Paper;
import info.androidhive.tabsswipe.R;
import java.util.ArrayList;
import java.util.List;
public class PaperAdapter extends BaseAdapter implements OnClickListener {
private Context context;
private List<Paper> papers;
private LayoutInflater inflater;
public PaperAdapter(Context context, List<Paper> papers) {
this.context = context;
this.papers = papers;
inflater = LayoutInflater.from(context);
}
#Override
public int getCount(){
return papers.size();
}
#Override
public Object getItem(int position) {
return papers.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View view, ViewGroup viewGroup) {
// We only create the view if its needed
if (view == null) {
view = inflater.inflate(R.layout.child_row, null);
// Set the click listener for the checkbox
view.findViewById(R.id.check1).setOnClickListener(this);
}
Paper p = (Paper) getItem(position);
// Set the example text and the state of the checkbox
CheckBox cb = (CheckBox) view.findViewById(R.id.check1);
//cb.setChecked(p.isSelected());
// We tag the data object to retrieve it on the click listener.
TextView paper = (TextView)view.findViewById(R.id.papername);
if (paper != null)
paper.setText(p.getTitle());
TextView author = (TextView)view.findViewById(R.id.authorname);
if( author!= null )
author.setText( p.getAuthor() );
return view;
}
/*#Override
/** Will be called when a checkbox has been clicked. */
public void onClick(View view) {
}
}

If I leave
//lv.setAdapter(listAdapter);
commented, it loads, but as soon as I uncomment it, it crashes with the following error:
12-06 11:28:05.240: E/AndroidRuntime(1362): java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.ListView
with reference to this precise line.

You make cast checkBox to ListView !
It should be like that.
ListView lv = (ListView) getActivity().findViewById(R.id.list);

I gusse here is the error in your code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_papers, container, false);
ListView lv = (ListView) getActivity().findViewById(R.id.check1);
//Here your casting checkBox to Listview Pleas Check it out
listAdapter = new PaperAdapter(getActivity(),papers);
//lv.setAdapter(listAdapter);
return v;
}
just replace it like
ListView lv = (ListView) v.findViewById(R.id.ListviewName);
