Fragment with different Viewpages

Fragment with different Viewpages - java

I got some error messages in my android studio when make fragment like the pictures.
This is an error messages :
error: incompatible types: TabFragment2 cannot be converted to Fragment
error: cannot find symbol method getSupportFragmentManager()
And this is my code :
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 mNumOfTabs;
public PagerAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
TabFragment1 tab1 = new TabFragment1();
return tab1;
case 1:
TabFragment2 tab2 = new TabFragment2();
return tab2;
case 2:
TabFragment3 tab3 = new TabFragment3();
return tab3;
default:
return null;
}
}
#Override
public int getCount() {
return mNumOfTabs;
}
}
TabFragment2.java
import android.app.Fragment;
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class TabFragment2 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.tab_fragment_2, container, false);
TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Image-1"));
tabLayout.addTab(tabLayout.newTab().setText("Image-2"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) view.findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter (getActivity().getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(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) {
}
});
return view;
}
}

TabFragment2.java should import android.support.v4.app.Fragment instead of import android.app.Fragment;

Android fragment tabbed layout, reselecting tab 3, listview disappears

When I select tab 3 my listview appears, yet when I select tab 1 and reselect tab 3, the listview doesn't appear.
Why is this?

Default ViewPager's offscreenPageLimit is 1. So the tab3 is detached when tab1 is re-selected. If fragment is detached, Fragment's views are destroyed.
see: ViewPager.setOffscreenPageLimit
So I recommend you to set offscreenPageLimit to 2.
viewPager.setOffscreenPageLimit(2);
Or you can hold the list of ArticleConstructor in Fragment3 like blew.
GetData.java:
public class GetData extends AsyncTask<String, String,ArrayList<ArticleConstructor>>{
Callback callback;
interface Callback {
void onArticleConstructorLoaded(ArrayList<ArticleConstructor> articleConstructors);
}
public GetData(Callback callback) {
this.callback = callback;
}
...
#Override
protected void onPostExecute(ArrayList<ArticleConstructor> result) {
callback.onArticleConstructorLoaded(result);
}
....
}
Fragment3.java:
public class Fragment3 extends Fragment implements GetData.Callback {
private ListView listView;
private ArrayList<ArticleConstructor> articleConstructors = new ArrayList<>();
private ArticleArrayAdapter adapter;
public Fragment3() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment3, container, false);
listView = (ListView) view.findViewById(R.id.listView);
adapter = new ArticleArrayAdapter(getActivity(), getContext(), articleConstructors);
listView.setAdapter(adapter);
return view;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (articleConstructors.size() == 0) {
GetData getData = new GetData(this);
getData.execute("lincoln");
}
}
#Override
public void onArticleConstructorLoaded(ArrayList<ArticleConstructor> articleConstructors) {
this.articleConstructors = articleConstructors;
adapter.setArticleConstructors(articleConstructors);
}
}

This is error ScreenShot

See your screenshot. You Import/extend android.app.Fragment;in DetailOneFragment and use android.app.support...Fragment in your other class

replace
import android.app.Fragment;
with
import android.support.v4.app.Fragment;
in your fragments

As of 02-2021 the solution above did work for me but i had to replace :
import android.app.Fragment;
with
import androidx.fragment.app.Fragment;
instead

How can I integrated LibGDX in Android application (Fragment)

When I run the Android Application there is some initialize and after that THERE IS connection to server when the connection end, I see on the screen Three Fragment Tabs.
Tab1 - Welcome to app.
Tab2 - Make some calculation.
tab3 - Game.
I want only when user type on "tab3 - game" to start/run active the LibGDX.
How can I do it?
Many Thanks For any help.

How do I use the navigation drawer to select a viewpager

I'm completely new to android app development and I'm currently working on a project for school.
From my understanding so far, you can use the navigation drawer to swap out UI fragments.
I made a nav drawer that's working properly so far based on the tutorial given here:
https://developer.android.com/training/implementing-navigation/nav-drawer.html
I'm trying to have it switch views for each item that's selected. I made a view pager fragment activity and I want the program to replace the view with my view pager upon selecting the 4th item in the nav drawer (index 3). I added a switch statement in my fragment class to determine which layout to load.
Here's the activity for the nav drawer:
package com.mkge.mkg;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.widget.DrawerLayout;

import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class MainActivity extends FragmentActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mTitle;
private String[] mPageTitles;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = getTitle();
mPageTitles = getResources().getStringArray(R.array.nav_draw_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, mPageTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close
) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(R.string.drawer_open);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
selectItem(0);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) return true;
return super.onOptionsItemSelected(item);
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
private void selectItem(int position) {
Fragment fragment = new PageFragment();
Bundle args = new Bundle();
args.putInt(PageFragment.ARG_PAGE_NUMBER, position);
fragment.setArguments(args);
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
setTitle(mPageTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
public static class PageFragment extends Fragment {
public static final String ARG_PAGE_NUMBER = "page_number";
public PageFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
int i = getArguments().getInt(ARG_PAGE_NUMBER);
View rootView;
switch(i) {
case 0:
rootView = inflater.inflate(R.layout.page_home, container, false);
break;
case 1:
rootView = inflater.inflate(R.layout.page_services, container, false);
break;
case 2:
rootView = inflater.inflate(R.layout.page_packages, container, false);
break;
case 3:
View view = new MeetViewPager().getViewPager();
rootView = view;
break;
case 4:
rootView = inflater.inflate(R.layout.page_about, container, false);
break;
case 5:
rootView = inflater.inflate(R.layout.page_contact, container, false);
break;
case 6:
rootView = inflater.inflate(R.layout.page_extras, container, false);
break;
default:
rootView = null;
}
String page = getResources().getStringArray(R.array.nav_draw_array)[i];
getActivity().setTitle(page);
return rootView;
}
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getActionBar().setTitle(mTitle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
I made this fragment activity here to create the view pager. I tried taking the view pager object I made here and passing it to the switch statement to my nav drawer activity.

Any help would be appreciated thanks.

mViewPager.setCurrentItem(0);
This should be all you need to make your ViewPager change to the first tab.
This would be called from inside your selectItem() method.
