FragmentPagerAdapter always starts from the first page

I have a Fragment pager adapter with five fragments and inside the third fragment I want to call an other activity which sends a selected picture to the container. It works fine but, every time the picture is selected from the other activity and the pager adapter starts from the first fragment in the fragment-activity instead of third fragment-activity. Do I have to force the pager adapter from the other activity or should I change something in the fragment-activity?
Code:
Fragment-activity:

Other Activity:
package com.example.android.womb_the_game;
import androidx.fragment.app.FragmentActivity;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.ImageButton;
import android.widget.ImageView;
public class choose_dice_column extends FragmentActivity {
private ImageButton b1;
private ImageView im1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_choose_dice_column);
this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
b1 = (ImageButton) findViewById(R.id.b1);
im1 = findViewById(R.id.im1);
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent i = new Intent(choose_dice_column.this, Circulation.class);
i.putExtra("resid1",R.drawable.n1);
startActivity(i);
}
});
}
}

The problem is, whenever you get back to your activity, you are creating a new adapter. So add the following to your Circulation-Activity to keep the state of the adapter:
if(adapterViewPager == null)
{
adapterViewPager = new Adapter_Circulation(getSupportFragmentManager(), this);
}

Android: FragmentManager returns blank fragment layout when new Fragment is inflated - onCreateView() method is not called at all

Hi my fragment does not get inflated inside a frame layout. please help here is my code:
My MainActivity extends AppCompatActivity and not FragmentActivity because i need to use actionbar.
public void showFragmentWomen(String title) {
showFragment(FragmentWomen.newInstance(title), false);
}
private void showFragment(Fragment fragment, boolean allowStateLoss) {
FragmentManager fm = mFragmentManager;
FragmentTransaction ft = fm.beginTransaction().replace(R.id.container, fragment);
ft.addToBackStack(null);
if (allowStateLoss || !BuildConfig.DEBUG) {
ft.commitAllowingStateLoss();
} else {
ft.commit();
}
fm.executePendingTransactions();
}

Why won't Fragment Transaction work?

I'm writing a simple program in which a two fragments and one activity is used. Both Fragments are displayed (one at a time) within the activity's Frame Layout. The first fragment is a listview that lists items from which the user can select, then the main activity should swap the first fragment with a detail fragment according to the item position determined by a listener within the first fragment. Trouble is, my program won't actually commence the swap. Here's the code for the activity:
package com.example.user.monkeys;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.util.Log;
public class ListActivity extends FragmentActivity implements
monkeyListFragment.OnMonkeySelectedListener {
#Override
public void onCreate(Bundle savedInstanceState) {
Log.i("Activity", "onCreate Pre-Fragment 1");
super.onCreate(savedInstanceState);
setContentView(R.layout.monkey_list_frame);
if (findViewById(R.id.fragment_container) != null) {
if (savedInstanceState != null) {
return;
}
monkeyListFragment monkeyList = new monkeyListFragment();
monkeyList.setArguments(getIntent().getExtras());
// Add the fragment to the container
getSupportFragmentManager().beginTransaction()
.add(R.id.fragment_container, monkeyList);
Log.i("Activity", "made it end onCreate");
}
}
#Override
public void onMonkeyItemSelected(int position) {
Log.i("From Activity", "onMonkeyItemSelected");
monkeyDetailsFragment newDetailFrag = new monkeyDetailsFragment();
Bundle args = new Bundle();
args.putInt("itemPosition", position);
newDetailFrag.setArguments(args);
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragment_container, newDetailFrag);
transaction.addToBackStack(null);
transaction.commit();
}
}
And the code for the listview fragment:
package com.example.user.monkeys;
import android.app.Activity;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class monkeyListFragment extends Fragment{
OnMonkeySelectedListener monkeyCallBack;
private ListView monkeyLV;
private String[] monkeyStrings;
public interface OnMonkeySelectedListener {
public void onMonkeyItemSelected(int position);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
Log.i("Fragment 1", "Made it to onCreateView");
View view = inflater.inflate(R.layout.list_fragment, container, false);
monkeyLV = (ListView) view.findViewById(R.id.monkeyListView);
monkeyStrings = getResources().getStringArray(R.array.monkey_data_list);
ArrayAdapter<String> objAdapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1, monkeyStrings);
monkeyLV.setAdapter(objAdapter);
AdapterView.OnItemClickListener monkeyListen = new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.i("ListFragment-ClckLstnr", "Made it");
monkeyCallBack.onMonkeyItemSelected(position);
}
};
Log.i("Fragment 1", "Made it past OnItemClick Listener");
return view;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
monkeyCallBack = (OnMonkeySelectedListener) activity;
}
catch (ClassCastException e) {
throw new ClassCastException(activity.toString());
}
}
}
and finally the code for the detail fragment (this isn't fully fleshed out but it should still swap I believe).
package com.example.user.monkeys;
import android.app.Activity;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class monkeyDetailsFragment extends Fragment {
ImageView monkeyPicture;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup
container, #Nullable Bundle savedInstanceState) {
Log.i("From Detail Fragment", "Got here");
View view = inflater.inflate(R.layout.monkey_detail_fragment, container,
false);
return view;
}
}

I found your missing line of code for the listview fragment:
monkeyLV.setOnItemClickListener(monkeyListen)

Pass data from Activity to SupportMapFragment

I have two fragments and one activity.
DataFragment passes info succesfuly to MainActivity and that's why there is no point providing you the code of it. My issue is , that bundle isn't effective on MyMapFragment which extends SupportMapFragment when I am trying to pass data from MainActivity. Of course I've searched a lot for many days but the only solutions given are for a fragment and not for SupportMapFragment which I think it's different.
MainActivity
package com.manuelpap.mapapp;
import android.app.Fragment;
import android.content.Intent;
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.os.Bundle;
import android.util.Log;
import android.os.Handler;
import com.google.android.gms.maps.SupportMapFragment;
import com.parse.Parse;
public class MainActivity extends AppCompatActivity {
public String mapLocation="EMPTY";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(new MyAdapter(getSupportFragmentManager()));
Intent intent = getIntent();
if (getIntent().getExtras() != null) {
mapLocation = intent.getExtras().getString("mapLocation");
Bundle bundle=new Bundle();
bundle.putString("message", "From Activity");
MyMapFragment fragobj=new MyMapFragment();
fragobj.setArguments(bundle);
Log.d("MAPLOCATION", "----MainActivity---- " + mapLocation);
finish(); //I am using this because on DataFragment it's starting again , so I don't need multiple instances of MainActivity
}
}
public class MyAdapter extends FragmentPagerAdapter{
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public android.support.v4.app.Fragment getItem(int i){
if(i==0){
return new DataFragment();
}
else {
return new MyMapFragment();
}
}
#Override
public int getCount(){
return 2; //posa scrolls dexia (pages) theloume
}
#Override
public CharSequence getPageTitle(int position) {
if(position==0){
return "DATA";
}
else {
return "MAP";
}
}
}
}
MyMapFragment
package com.manuelpap.mapapp;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.os.Handler;
import com.google.android.gms.maps.GoogleMap;

public String location="EMPTY";
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final Handler handler=new Handler();
handler.post(new Runnable() {
#Override
public void run() {
if (getArguments() == null)
location = "------NOTHING RECIEVED------";
else
location =getArguments().getString("message");
Log.d("MAPFRAGMENTLOCATION", location);
handler.postDelayed(this, 200); // set time here to refresh textView
}
});
GoogleMap googleMap = getMap();
googleMap.setMyLocationEnabled(true);
googleMap.getUiSettings().setZoomControlsEnabled(true);
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(new LatLng(40.416775, -3.70379));
googleMap.addMarker(markerOptions);
}
}

It looks like you are finishing your main activity
//I am using this because on DataFragment it's starting again , so I don't need multiple instances of MainActivity
Your DataFragment is in the viewpager so it is supposed to start along with your map fragment. You are not starting multiple instances of main activity that I can see here.
When you call finish() on your main activity that means that the map and pager and everything goes away. Not sure what exactly your looking for but I assume you are trying to pass the location string to the map so I have tailored my answer to fit that use case.
The problem is that you are using new MyMapFragment() without the bundle in the view pager. The other logic that you have in MainActivity pertaining to the Map fragment is not going anything to the one that is displayed with the view pager. Essentially you are just creating another instance of the map fragment that is not displayed anywhere. The view pager is the class that needs the data passed to it.
I thought this link might be helpful here to explain the newInstance Method.
Creating a Fragment: constructor vs newInstance()
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
if (getIntent().getExtras() != null) {
mapLocation = intent.getExtras().getString("mapLocation");
}
viewPager.setAdapter(new MyAdapter(getSupportFragmentManager(), mapLocation));
}
public class MyAdapter extends FragmentPagerAdapter{
private String mMapLocation;
public MyAdapter(FragmentManager fm, String mapLocation) {
super(fm);
mMapLoaction = mapLocation;
}
#Override
public android.support.v4.app.Fragment getItem(int i){
if(i==0){
return new DataFragment();
}
else {
Bundle bndl = new Bundle();
if(!TextUtils.isEmpty(mapLocation))
bndl.putString("message", mapLocation);
return new MyMapFragment.newInstance(bndl);
}
}
public class MyMapFragment extends SupportMapFragment { //kanei extend thn hdh uparxousa class gia to maps ths google alla den mpoorume na thn doume giati einai kleidomenh

Destroy activity containing two fragments after clicking Andorid Back Button

Problem SOLVED!
ISSUE:
I have problem, and I can't find any solution. I have Maps_Activity, which contains two fragments. Both fragments show google maps v2 and I display them on screen thanks to two ActionBar tabs.
The problem is appearing when I want to return to previous activity. When I click Android back button, my whole application turns down, shows pupup, that my application was stopped.
What I should add to my code to remove this error?
Solution:
Maps_Activity.java
import android.app.ActionBar;
import android.app.Activity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.util.Log;
import android.widget.Button;
import com.google.android.gms.maps.MapFragment;
public class Maps_Activity extends Activity {
public static FragmentManager manager;
Fragment fragmentTab1 = new Medical_Shops_Map();
Fragment fragmentTab2 = new Medical_Clicnics_Map();
Button Medical_Shops_Button, Medical_Clinics_Button;
ActionBar actionBar ;
#Override
public void onCreate(Bundle arg0) {
super.onCreate(arg0);
setContentView(R.layout.activity_maps_);
manager = getFragmentManager();
actionBar=getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab tab1=actionBar.newTab();
tab1.setText("Apteki 24H/7");
tab1.setTabListener(new MyTabsListener(fragmentTab1));
ActionBar.Tab tab2=actionBar.newTab();
tab2.setText("Przychodnie Lekarskie");
tab2.setTabListener(new MyTabsListener(fragmentTab2));
actionBar.addTab(tab1);
actionBar.addTab(tab2);
}
protected class MyTabsListener implements ActionBar.TabListener {
private Fragment fragment;
public MyTabsListener(Fragment fragment) {
this.fragment = fragment;
}
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
}
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
ft = manager.beginTransaction();
ft.replace(R.id.map_container, fragment);
ft.commit();
Log.e("Activity", "Fragment replace");
}
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
// some people needed this line as well to make it work:
MapFragment mMap2 = ((MapFragment) Maps_Activity.manager.findFragmentById(R.id.map));
ft = manager.beginTransaction();
if(mMap2!=null)
{
ft.remove(mMap2);
ft.commit();
Log.e("Activity", "Mapa_fragment destroy");
}
else
{
MapFragment mMap1 = ((MapFragment) Maps_Activity.manager.findFragmentById(R.id.map1));
ft.remove(mMap1);
ft.commit();
Log.e("Activity", "Mapa_fragment2 destroy");
}
}
}
}
One of the fragments:
import android.os.Bundle;
import android.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;

import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class Medical_Clicnics_Map extends Fragment implements OnMapReadyCallback {
private static View view;
private static GoogleMap mMap2;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.medical__clicnics__map, container, false);
setUpMapIfNeeded();
return view;
}
public void setUpMapIfNeeded() {
MapFragment mMap2 = ((MapFragment) Maps_Activity.manager
.findFragmentById(R.id.map1));
mMap2.getMapAsync(Medical_Clicnics_Map.this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
Log.d("Activity", "Map ready");
googleMap.setMyLocationEnabled(true);
LatLng sydney = new LatLng(-33.867, 151.206);
googleMap.addMarker(new MarkerOptions()
.title("Sydney")
.snippet("The most populous city in Australia.")
.position(sydney));
}
}
Maybe for someone this code will be helpful ;)
