SwipeView change the content of 2 pages

SwipeView change the content of 2 pages - java

I've created a new activity with swipe views, and added some code.
I have now two swipeable pages, but with the same content, how can i change the content of the second swipe page.
Do I have to create a new activity or just to redirect it to another xml?

thanks!

based on the page number you get from Placeholder Fragment you can set the new content

on your PlaceholderFragment class you can get current page position passed from newInstance method.after that, you can change your fragment content according page section number

There are many ways to do this. You don't have to create another Activity.
Below is a simple way, it rewrites your PlaceholderFragment and make it return different view in different position on onCreateView.
public static class PlaceholderFragment extends Fragment {
private int position;
public static PlaceholderFragment newInstance(int sectionNumber) {
return new PlaceholderFragment(sectionNumber);
}
public PlaceholderFragment(int sectionNumber) {
this.position = sectionNumber;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View rootView;
switch(position){
case 1:
rootView = inflater.inflate(..);
//init view widget.
break;
case 2:
rootView = inflater.inflate(..);
//init view widget.
break;
}
return rootView;
}
}

View myView = inflater.inflate(R.layout.medicard_fragment, container, false);
fabAdd = (FloatingActionButton) myView.findViewById(R.id.floatButtonAdd);
fabAdd.setOnClickListener(this);
return myView;
}
#Override
public void onClick(View v) {
Toast.makeText(mContext,"ADDING", Toast.LENGTH_SHORT).show();
}
}
I really dont know what to do anymore
I tried putting my code for the fab in the adapter which only cause a nullpointer exception which is i think is right since its in a different fragment

Create an instance variable to hold your recyclerAdapter in your fragment. Then you can have the FAB click listener add a MediaCard to mData.
Then call
recyclerAdapter.notifyDataSetChanged();

Thank you very much

Your activity doesn't extend FragmentActivity from the support library, therefore you cannot call this method.
So you need something like that:
public class HorizontalCoordinatorNtbAndTabbedActivity extends FragmentActivity implements View.OnClickListener {
and then cast:
((HorizontalCoordinatorNtbAndTabbedActivity)getActivity()).getSupportFragmentManager()
Plus ViewPager inside ViewPager - it's not a good idea.

Try to use FragmentStatePagerAdapter instead of FragmentPagerAdapter. It could and possibly solve some possible problems.
Pass SupportFrogmentManager to FragmentStatePagerAdapter if inside it you are using fragments from support library. In other case - pass FragmentManager.
Depending on your view hierarchy you can try to get ChildFragmentManager.
Try to move ViewPager from fragment to activity.

Sorry I can't speak well. Thank you very much.

Try to load WebView with URL in onCreateView() with check first section case from PlaceholderFragment as below :
if (getArguments().getInt(ARG_SECTION_NUMBER) == 1) {
View rootView = inflater.inflate(R.layout.fragment_sub_page01, container, false);
mWebView = (WebView) rootView.findViewById(R.id.webview);
mWebView.loadUrl("http://www.google.com")
return rootView;
}
Another way to achieve using each Fragment class :
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
if(position==0){
return SubPage01.newInstance(position + 1);
}else if(position==1){
return SubPage02.newInstance(position + 1);
}else{
return SubPage03.newInstance(position + 1);
}
}
#Override
public int getCount() {
// Show 3 total pages.
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Page 01";
case 1:
return "Page 02";
case 2:
return "SECTION 3";
}
return null;
}
}

Android Studio, how add fragments to my tab menu?

I found a tab navigation snippet online and I wonder how to add multiple fragment to it.
I would like to make it work that way:
If i choose first position in menu, it will open fragment_one.xml.
If i choose second position in menu, it will open fragment_two.xml.
Currently, I have only 1 fragment and I dont know how add more.
package com.example.myapp;

});
for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {

}
}

#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,

View rootView = inflater.inflate(R.layout.fragment_omnie, container, false);
return rootView;
}
}
}

Well you need to create 3 diffrent fragments Like your "PlaceholderFragment"
and In SectionPagerAdapter
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch(position)
{
case 0: return PlaceholderFragment.newInstance(position + 1);
case 1: return FirstFragment(position + 1);
case n: return nthFragment(position + 1);
}
}
#Override
public int getCount() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
Locale l = Locale.getDefault();
switch (position) {
case 0:
return getString(R.string.title_section1).toUpperCase(l);
case 1:
return getString(R.string.title_section2).toUpperCase(l);
case 2:
return getString(R.string.title_section3).toUpperCase(l);
}
return null;
}
}

Getting error in showing activity via Fragment

I am trying to show one my pages in fragments but it is giving me an error.
I have created a separate Class file called FragmentContacts.java, from where i show the layout of activity_contacts.xml.
FragmentContacts Java Code:
package me.example.app;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentContacts extends FragmentActivity {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Get the view from fragmenttab1.xml
View view = inflater.inflate(R.layout.activity_contacts, container, false);
return view;
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
// setUserVisibleHint(true);
}
}
Fragment Code:
public Fragment getItem(int arg0) {
// getItem is called to instantiate the fragment for the given page.
// Return a DummySectionFragment (defined as a static inner class
// below) with the page number as its lone argument.
//Fragment fragment = new DummySectionFragment();
//Bundle args = new Bundle();
//args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, position + 1);
//fragment.setArguments(args);
//return fragment;
switch (arg0) {
// Open FragmentTab1.java Error on return fragmenttab1
case 0:
FragmentContacts fragmenttab1 = new FragmentContacts();
return fragmenttab1;
return null;
}

Resolved!
This what I did:
1) I made Fragment Class separately for each tab.
2) Then i used the case in order to show each activity in their respective tab.
(sorry for my lack of technical words.)

We Keep Coding

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

SwipeView change the content of 2 pages - java

based on the page number you get from Placeholder Fragment you can set the new content

on your PlaceholderFragment class you can get current page position passed from newInstance method.after that, you can change your fragment content according page section number
