Need some help for design for layout in android

I have ListView which brings data from server using AsyncTask. After that onItemClick starts a new Activity which should show more detailed info of the clicked item from the ListView. Pretty simple . But problem is the individual pages should work like 9GAG android app (i.e Swipeable Fragment with ViewPager). The detail info is much more. What are your suggestion for design layout of that page. Currently I am using ViewPager on that single page and Design the fragment to get the required thing.
Code
public class IndividualPage extends ActionBarActivity{
ArrayList<Item> arrayOfList;
ViewPager pager;
CountryPageAdapter pageAdapter;
private ProgressBar mProgress;
#Override
public void onCreate (Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.secondpage);
mProgress = (ProgressBar) findViewById(R.id.linear_progress_bar);
new FilteredResult().execute();
pager = (ViewPager)findViewById(R.id.viewpager);
}
private List<Fragment> getFragments() {
List<Fragment> frags = new ArrayList<Fragment>();
System.out.println("fragments main ayya hai");
cats=arrayOfList;
for(int i = 0;i<cats.size();i++ ) {
System.out.println("number : "+i+"::"+cats.get(i).getSector());
frags.add(prepareFragment(cats.get(i).getImage(),cats.get(i).getName(),cats.get(i).getLocation(),cats.get(i).getSector(),cats.get(i).getStatus(),cats.get(i).getFounded(),cats.get(i).getFundRaising()));
}
return frags;
}
Fragment prepareFragment(String image,String name,String location,String Expertise,String sector,int founded,String fund) {
CountryFragment cf = new CountryFragment();
Bundle args = new Bundle();
args.putString(CountryFragment.STARTUP_IMAGE, image);
args.putString(CountryFragment.STARTUP_NAME, name);
args.putString(CountryFragment.STARTUP_LOCATION, location);
args.putString(CountryFragment.STARTUP_EXP, Expertise);
args.putString(CountryFragment.STARTUP_SEC, sector);
args.putInt(CountryFragment.STARTUP_FOUNDED, founded);
args.putString(CountryFragment.STARTUP_FUND, fund);
cf.setArguments(args);
return cf;
}
[![public class FilteredResult extends AsyncTask<String, Void, String> {
//onpreexcute nothing doing great in this
//onbackground
#Override
protected void onPostExecute(String result) {
List<Fragment> fragments = getFragments();
pageAdapter = new CountryPageAdapter(getSupportFragmentManager(), fragments);
pager.setAdapter(pageAdapter);
}
}]

I personally prefer ViewPagers to ScrollViews as they do not keep all of the fragment/views in the memory.
Also each individual item is independent of the other ones. For example if you want to be able to implement vertical scrolling for each item you cannot do it with HorizontalScrollView as all the views will scroll together.

Even im having the same kind of design i have done like this

App force close on viewPager.setAdapter(adapter)

I have an application page with viewpager containing two fragments.
When my activity pops up , a server request is made for loading current data and then adapter is set.
But the app crashes with the following error.
Attempt to invoke virtual method 'void android.support.v4.app.Fragment.setMenuVisibility(boolean)' on a null object reference
While debugging, viewPager.setAdapter(adapter) showed null pointer exception. Neither my viewPager is null nor my Adapter.
I am not able to figure out why this is happening.
Please help!!
Thanks in advance!!

Found the problem.. In my fragmentPagerAdapter, getItem() was returning null for a fragment.

Try this code
create a class file TabOne.java
package com.example.tabfragment;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class TabOne extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab_one, null);
return rootView;
}
}
create a class file TabTwo.java
package com.example.tabfragment;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class TabTwo extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab_two, null);
return rootView;
}
}
**create xml file tab_one.xml and tab_two.xml **

View Pager with huge number of fragment

I have to change the views on swipe. This can be obtained through view pager. But I have 60 views and creating 60 different fragment will not be a good approach.
Please someone guide me what will be the best way to design swiping 60 views.

Firstly create one fragment where you can inflate different views using "position" parameter as follow..
public class SuperAwesomeCardFragment extends Fragment {
private static final String ARG_POSITION = "position";
private int position;
View mainView;
public static SuperAwesomeCardFragment newInstance(int position) {
SuperAwesomeCardFragment f = new SuperAwesomeCardFragment();
Bundle b = new Bundle();
b.putInt(ARG_POSITION, position);
f.setArguments(b);
return f;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
position = getArguments().getInt(ARG_POSITION);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if(position==1){
mainview = inflater.inflate(R.layout.layout1, null);
}else if(position==2){
mainview =inflater.inflate(R.layout.layout2, null);
.
.
.
.
}else if(position==50){
mainview =inflater.inflate(R.layout.layout50, null);
}
return mainView;
}
}
Now in Your MainActivity Create an Adapter that extends FragmentPagerAdpater and in getItem() method create the instances of previously create fragment as follow
public class MyPagerAdapter extends FragmentPagerAdapter {
private final String[] TITLES = { "Title1", "Title2"...., "Title50"};
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public CharSequence getPageTitle(int position) {
return TITLES[position];
}
#Override
public int getCount() {
return TITLES.length;
}
#Override
public Fragment getItem(int position) {
return SuperAwesomeCardFragment.newInstance(position);
}
}
}
Then finally add this in your Activity's OnCreat() method...
MyPagerAdapter adapter = new MyPagerAdapter(getSupportFragmentManager());
yourViewPager.setAdapter(adapter);
Thus you will have to create single fragment and use it for multiple views.
Thank you. Hope it helps..!!

You can safely use the ViewPager with an implementation of FragmentStatePagerAdapter. The adapter will optimize the memory usage by destroying fragments that are not visible at a given moment. Check the documentation for details and code sample.

Below is the complete code to add Fragments to a View pager.
Since this is just a demonstration I have used just a textView and each fragment added will have a random colour.On clicking a button you can add as many fragments as you want.On clicking the Page you can just remove it from the View Pager.You can move from one Page to another in a View Pager by Swiping to the right or left.

Creating ListView with android.support.v4.view.ViewPager showing nothing

I'm trying to create a ListView that each cell can be shifted as ViewPager.
Similar to Google Gmail app, that can shift emails in order to delete the emails.
It is working BUT showing nothing.
I created a ListView with BaseAdapter.
The Adapter create ViewPager with PagerAdapter that implements FragmentStatePagerAdapter.
The PagerAdapter activate the Fragment that supposed to show the data at the cells in the pagers.
Can you please help?

ViewPager in ListView is a bad idea.
You can use this Swipe-to-Dismiss library for deleting https://github.com/romannurik/android-swipetodismiss

You go through following link to implement gmail like delete from list function:

ListView no longer display inside Tab

I haven't touched this codebase in a couple of months. Now that I've picked it up again, some code that I didn't think I'd changed has stopped working: All listfragment listviews in the app populated by a simplecursoradapter have stopped working and are just blank. At first I thought the cursor or the database was at fault or that perhaps the adapter wasn't being set correctly, so I added some debugging to the onLoadFinished:
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
Log.d("IndexListFragment", "Rows returned: " + cursor.getCount());
Log.d("IndexListFragment", cursor.getColumnName(0));
Log.d("IndexListFragment", mAdapter.toString());
Log.d("IndexListFragment", this.getListView().getAdapter().toString());
mAdapter.swapCursor(cursor);
}
This returns what I'd expect:
IndexListFragment: Rows returned: 2324
IndexListFragment: _id
IndexListFragment: android.support.v4.widget.SimpleCursorAdapter#41d06a18
IndexListFragment: android.support.v4.widget.SimpleCursorAdapter#41d06a18
So as far as I can tell, the cursor is there and full of data, but swapping it in doesn't get the listview populated. Any ideas?
For completeness, here's the onCreate where the adapter is created and set:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] from = new String[] { GuidebookProvider.COL_NAME,
GuidebookProvider.COL_GRADE };
int[] to = new int[] { android.R.id.text1, android.R.id.text2 };
mAdapter = new SimpleCursorAdapter(getActivity(),
android.R.layout.simple_list_item_2, null, from, to, 0);
setListAdapter(mAdapter);
getLoaderManager().initLoader(0, null, this);
}
And the onCreateLoader:
#Override
public Loader<Cursor> onCreateLoader(int loaderId, Bundle loaderArgs) {
String orderBy = GuidebookProvider.COL_NAME;
String[] projection = new String[] { GuidebookProvider.COL_ID, GuidebookProvider.COL_NAME, GuidebookProvider.COL_GRADE };
return new CursorLoader(getActivity(),
GuidebookProvider.CONTENT_URI_CLIMB, projection, null, null,
orderBy);
}
Edit: I've done a little more work debugging this issue. The fragment works fine if I run it directly from an activity like this:
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.widget.FrameLayout;
public class TestActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FrameLayout frame = new FrameLayout(this);
frame.setId(android.R.id.content);
if (savedInstanceState == null) {
Bundle args = new Bundle();
args.putInt(IndexListFragment.ARGUMENT_INDEX_TYPE, IndexListFragment.IndexType.ALPHA.value);
Fragment indexListFragment = new IndexListFragment();
indexListFragment.setArguments(args);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(android.R.id.content, indexListFragment).commit();
}
}
}
However, calling it as part of a Tab ends up with a blank tab:
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTabHost;
public class TestActivity extends FragmentActivity {
private FragmentTabHost mTabHost;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_tab_host);
mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
Bundle args = new Bundle();
args.putInt(IndexListFragment.ARGUMENT_INDEX_TYPE,
IndexListFragment.IndexType.ALPHA.value);
Drawable drawable = null;
mTabHost.addTab(mTabHost.newTabSpec("A-Z")
.setIndicator("A-Z", drawable), IndexListFragment.class, args);
}
}
Here's my xml for the tabhost:
<?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" >
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0" />
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1" />
</android.support.v4.app.FragmentTabHost>
</LinearLayout>
The fact that the fragment populates correctly when called directly but not when called from within a tab seems to show that the problem isn't at all with the cursors or adapters but with the way the listfragment operating inside a tab.
Can anyone point out what I've done wrong (or what's changed in the last couple of updates of the SDK) to break this code? It used to work fine.

This Code may help you just try it

Got a chance to have a look at this today and finally sorted it out. The problem was in my xml layout setup. Oddly, according to my git repository, this file hasn't changed for 9 months so I guess I was doing something that only worked by accident. I found a tutorial FragmentTabHosts with a different layout and updated my layout to:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0" />
</android.support.v4.app.FragmentTabHost>
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1" />
</LinearLayout>
That somehow fixed the issue. A bit more hunting around revealed an example layout xml for FragmentTabHost in the TabActivity documentation: http://developer.android.com/reference/android/app/TabActivity.html
I updated to use the version found in the documentation and it also works:
<android.support.v4.app.FragmentTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TabWidget
android:id="#android:id/tabs"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0"/>
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
Given I found it in Android's documentation, I'll stick with this version.
