Why can't I see any changes in my "Place" tab

I want each tab to to show something different. To start things off, I want to make changes to the Place tab. The problem is, none of the changes are being reflected in the Android Simulator.
Image of what I'm referring to
In this case, I want the text something to show up, but it's not. What am I doing wrong? I've also included code that might be relevant to this issue.
Here's MainActivity.java:
import android.net.Uri;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.Arrays;
public class MainActivity extends AppCompatActivity implements Place.OnFragmentInteractionListener, Profile.OnFragmentInteractionListener, Take.OnFragmentInteractionListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabLayout tabLayout = (TabLayout)findViewById(R.id.tabLayout);
tabLayout.addTab(tabLayout.newTab().setText("Place"));
tabLayout.addTab(tabLayout.newTab().setText("Take"));
tabLayout.addTab(tabLayout.newTab().setText("Profile"));
final ViewPager viewPager = (ViewPager)findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager(),tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.setOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
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) {
}
});
}
#Override
public void onFragmentInteraction(Uri uri) {
}
}
Here's fragment_place.xml:
<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"
<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Place"
android:layout_centerInParent="true"
android:textSize="30dp"
android:id="#+id/textView" />
<EditText
android:id="#+id/editText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="41dp"
android:layout_marginStart="41dp"
android:layout_marginTop="80dp"
android:ems="10"
android:inputType="textPersonName"
android:text="Something" />
</RelativeLayout>
Here's PagerAdapter.java:
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
public class PagerAdapter extends FragmentStatePagerAdapter {
int mNoOfTabs;
public PagerAdapter(FragmentManager fm, int NumberOfTabs) {
super(fm);
this.mNoOfTabs = NumberOfTabs; // set global number of tabs to local number of tabs
}
#Override
public Fragment getItem(int position) {
switch(position) {
case 0:
Place place = new Place();
return place;
case 1:
Profile profile = new Profile();
return profile;
case 2:
Take take = new Take();
return take;
default:
return null;
}
}
#Override
public int getCount() {
return 0;
}
}

I don't see in your code where you provide the layout xml to the fragment

Change the lines to given code.
#Override
public int getCount() {
return mNoOfTabs ;
}
Also make sure you inflate the layout belong to Place (Fragment) onViewCreated() method

fragment and appcompact activity error

I tried to create a bar tabs in two activities (Testactivity and Page1 related with adapters for recylerview and listview...), but those activities classes are extended already to AppCompatActivity because I use some codes needs AppCompatActivity.
I try to write something like (public class Testactivity extends AppCompatActivity, Fragment) but it still shows the errors:

C:\Users\lenovo\Desktop\Nouveau dossier\MyApplication\app\src\main\java\com\example\lenovo\myapplication\Testactivity.java
error:'{'expected
the { must be before fragment in
public class Page1 extends AppCompatActivity, Fragment
and
public class Testactivity extends AppCompatActivity, Fragment
Any help will be appreciated!

As the following error says:
'onStop()' in 'android.support.v7.app.appcompatactivity' clashes with 'onStop()' in 'android.support.v4.app.fragment'; attempting to assign weaker access privileges 'protected'; was 'public' class cannot extend multiple classes
it is because Java language doesn't support multiple inheritance more about it at Why not multiple inheritance?
So, the following code is wrong:
public class Page1 extends AppCompatActivity, Fragment {
...
}
You need to extend the Page1 either with AppCompatActivity or Fragment but not both.
Because you want to use FragmentPagerAdapter with the following:
public class SectionsPagerAdapter extends FragmentPagerAdapter {
...
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
...
}
}
which is need Fragment as the return of getItem(). So, you need to extend the Page1 and Testactivity with Fragment.

The minimum sdk viersion for this app is 9 and maximus sdk is 21.
It will be very helpfull if anyone suggest me how to solve this problem.
Thank You.

You need to import
import android.support.v4.app.Fragment
instead of
import android.app.Fragment;
in your MainActivity

Here is the xml for this gameFragment
<?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"
android:background="#ff8400"
android:orientation="vertical" >
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textSize="20dp"
android:layout_centerInParent ="true"/>
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
</ListView>
</RelativeLayout>
The Other two customs listFragment classes and xml's are thesame.
I will appreciate any help out there

It looks like your emulator doesn't support the APIs you use, because the Android-version on your emulator is too low.
Try using an emulator with an android version > 4.0

Buttons within View Pager

I am trying to add buttons within a Fragment of PageView.
Please find attached the code that I am using for this application:
The specific code for the xml is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/banner_name"
android:layout_width="fill_parent"
android:layout_height="30dp"
android:background="#drawable/button_banner"
android:gravity="center_vertical"
android:paddingLeft="10dip"
android:text="#string/equations"
android:textStyle="bold"
android:textColor="#ffffff" />
</LinearLayout>
<ScrollView
android:id="#+id/ScrollViewEquations"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="#+id/Button"
android:layout_width="fill_parent"
android:layout_height="25dip"
android:background="#drawable/custom_button"
android:gravity="center_vertical"
android:paddingLeft="25dip"
android:textColor="#516CE2"
android:text="#string/button" />
</LinearLayout>
</ScrollView>
</LinearLayout
this is the associated fragment code
package com.example.app;
import com.example.app![enter image description here][1].R;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
public class EquationsMain extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.equations, container, false);
return view;
}
}
and this is the main code:
package com.example.app;
import com.example.app.R;
import com.google.ads.AdRequest;
import com.google.ads.AdView;
import android.os.Bundle;
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.view.Window;
import android.view.WindowManager;
public class Main extends FragmentActivity {
private MyAdapter mAdapter;
private ViewPager mPager;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
mAdapter = new MyAdapter(getSupportFragmentManager());
AdView adView = (AdView)this.findViewById(R.id.adView);
adView.loadAd(new AdRequest());
mPager = (ViewPager) findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
}
public static class MyAdapter extends FragmentPagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return 3;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new EquationsMain();
case 1:
return new MaterialsMain();
case 2:
return new AboutMain();
default:
return null;
}
}
}
}
