One solution would be , You should replace the activity with the fragment first and then pass arguments of top and bottom value to that fragment.
It would be something like
#Override
public void createMeme(String top, String bottom)
Fragment fragment = new BottomPictureFragment();
Bundle args = new Bundle();
args.putString("Top", top);
args.putString("Bottom",bottom);
fragment .setArguments(args);
FragmentManager frgManager = getSupportFragmentManager().beginTransaction().replace(R.id.activity_main, fragment).commit();
After doing this you can get the arguments in the BottomPictureFragment inside onCreateView() and call the setMeme(top,bottom) function from the onCreateView().

I try to make a TabLayout but it has an error

Here is my MainActivity.java:
public class MainActivity extends AppCompatActivity {

setContentView(R.layout.activity_main);
tabLayout.findViewById(R.id.tabLayout);
viewPager.findViewById(R.id.viewPager);
tabLayout.setupWithViewPager(viewPager);
VPAdapter vpAdapter = new VPAdapter(getSupportFragmentManager(), FragmentPagerAdapter.BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);
vpAdapter.addFragment(new statistics(),"Statistics");
vpAdapter.addFragment(new connectivity(),"Connectivity");
vpAdapter.addFragment(new maskSensor(),"Mask Sensor");
viewPager.setAdapter(vpAdapter);

You are not initializing your TabLayout and ViewPager properly. Change these lines
tabLayout.findViewById(R.id.tabLayout);
viewPager.findViewById(R.id.viewPager);
to
tabLayout = findViewById(R.id.tabLayout);
viewPager = findViewById(R.id.viewPager);

how to resolve app has stopped? (appbarlayout and tablayout)

I am a beginner in android development and I have encountered some difficulty in running my app in the simulator. I am following chapter 12 of the head first textbook to design an app with tab navigation. It has four fragments and I am using the fragment pager adapter and tab layout to navigate through the app. When I run the app in the simulator it is crashed with the error message "app has stopped". My code for the main activity is as follows:
package com.hfad.bitsandpizzas;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import androidx.appcompat.widget.ShareActionProvider;
import androidx.appcompat.widget.Toolbar;
import androidx.core.view.MenuItemCompat;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentManager;
import androidx.fragment.app.FragmentPagerAdapter;
import androidx.viewpager.widget.ViewPager;
import com.google.android.material.tabs.TabLayout;
public class MainActivity extends AppCompatActivity {
private ShareActionProvider shareActionProvider;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
SectionsPagerAdapter pagerAdapter =
new SectionsPagerAdapter(getSupportFragmentManager());
ViewPager pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(pagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(pager);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem menuItem = menu.findItem(R.id.action_share);
shareActionProvider =
(ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);
setShareActionIntent("Want to join me for pizza?");
return super.onCreateOptionsMenu(menu);
}
private void setShareActionIntent(String text) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, text);
shareActionProvider.setShareIntent(intent);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_create_order:
Intent intent = new Intent(this, OrderActivity.class);
startActivity(intent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return 4;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new TopFragment();
case 1:
return new PizzaFragment();
case 2:
return new PastaFragment();
case 3:
return new StoresFragment();
}
return null;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return getResources().getText(R.string.home_tab);
case 1:
return getResources().getText(R.string.pizza_tab);
case 2:
return getResources().getText(R.string.pasta_tab);
case 3:
return getResources().getText(R.string.store_tab);
}
return null;
}
}
}

android.support.design.widget.AppBarLayout
You are using AppBarLayout & TabLayout from support libraries while using androidx project,
so you need to replace android.support.design.widget.AppBarLayout with com.google.android.material.appbar.AppBarLayout
And replace android.support.design.widget.TabLayout with com.google.android.material.tabs.TabLayout
So, change your layout to be:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:orientation="vertical"
tools:context="com.hfad.bitsandpizzas.MainActivity">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" />
<com.google.android.material.tabs.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.appbar.AppBarLayout>
<androidx.viewpager.widget.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>

You have added the floating action button in your activity_ownerhome.xml and you are initializing it in ownerhomeFragment.java.
So add your FloatingActionButton in fragmentownerhome.xml itself like this
<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:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.example.kun.carkila.ownerhome"
tools:showIn="#layout/activity_ownerhome">
<ListView
android:layout_width="match_parent"
android:layout_height="450sp"
android:id="#+id/lvOnwer"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true" />
<TextView
android:text="TextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="24dp"
android:textSize="30sp"
android:textColor="#color/colorPrimaryDark"
android:id="#+id/tvUser" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/plus" />
</RelativeLayout>
and remove the FloatingActionButton from your activity_ownerhome.xml file.

The cause of the crash is because your FAB xml code is in the "Activity layout", it is supposed to be in the "fragment layout" file
This is how i use FAB in a fragment
In my fragment layout file:
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
app:srcCompat="#android:drawable/ic_dialog_email" />
In my fragment class file:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_home, container, false);
FloatingActionButton fab = (FloatingActionButton) view.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();
}
});
return view;
}
And it works...
NOTE:
when i included android:backgroundTint="#android:color/transparent"
the application crashed and gave the error :
Binary XML file line #14: Error inflating class android.support.design.widget.FloatingActionButton
Hope this helps.

The problem isn't with the FAB, it's with how you inflate your view.
Replace this code in the Fragment:
View v = super.onCreateView(inflater, container, savedInstanceState);
getActivity().setContentView(R.layout.activity_ownerhome);
With this:
var v = inflater.inflate(R.layout.{your fragment xml}, container, false);
And remove this:
<fragment
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:name="com.example.kun.carkila.ownerFragment"
android:id="#+id/ownerhomeFragment"/>
You should define how you want your fragment xml to look, and then inflate it using the code inflater.inflate... and put in your fragment xml there, like I wrote above.
Update:
Instead of <include layout="#layout/content_ownerhome" /> place in this:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content_frame" />
Then in your Main Activity write this code:
getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, fragment).commit();
And you're supposed to see your fragment, if in the fragment you inflated your fragment xml correctly, as stated above.

You must implement the fragment in your main class something like...
public class ownerhome extends AppCompatActivity implement ownerhomeFragment {...

NullPointerException with onClickListener for elements in Fragment

I'm having a hell of a time getting fragments to work. The basis of this is to lave a login screen (fragment) appear by default when LoginActivity is created. The fragment has an TextView that when clicked, is supposed to launch a new fragment (form for lost password). I keep getting a NullPointerException when calling forgottenPassword.setOnClickListener from LoginActivity.
The project crashes before I can tell if anything else works.
I'm sure there's some glaring newbie error in here somewhere...
onCreate method from LoginActivity.java:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
if (savedInstanceState == null) {
FragmentManager fragmentManager = getFragmentManager();
int fragmentTransaction = fragmentManager.beginTransaction()
.add(R.id.login_screen_fragment, new FragmentLogin())
.commit();
}
// Listen for FORGOTTEN PASSWORD click event, open ForgottenPassword Fragment //
final TextView forgottenPassword = (TextView) findViewById(R.id.button_lost_pass);
forgottenPassword.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Do what I need this to do...
}
});

You have to find the View in your Fragment's layout.
Use the following in your FragmentLogin class:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.fragment_login, container, false);
final TextView forgottenPassword = (TextView) view.findViewById(R.id.button_lost_pass);
// Set your onClickListener here
return view;
}

Actually, your fragment might be not accessible when you assign forgetpassword , you can use the following for layout_login.xml:
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:name="FragmentLogin"
tools:layout="#layout/fragment_login"
/>
Note you may have to define the right path to FragmentLogin.
This is the new way to work with fragment, that will load your Login fragment automatically without writing anything in onCreate.
Also, it's not a TextView but a Button
Finally, remove the Fragment Transaction code.
Another option, is to move your forgot password button login to FragmentLogin. Because basically you try to access Fragment related element from the activity. Everything should be in your fragment.
You can still access the fragment manager with getActivity().getFragmentManger(), to load the lost_password layout.

What is the activity_login.xml content. I guest wrong id of button button_lost_pass

Inside oncreate() method you called new Fragment but the fragment layout(layout_lost_password) does not contain the id(R.id.button_lost_pass)

Change :
final TextView forgottenPassword = (TextView) findViewById(R.id.button_lost_pass);
To
final Button forgottenPassword = (Button) findViewById(R.id.button_lost_pass);
