Android swipe view with view pager - android

Based on android Creating Swipe Views with Tabs
http://developer.android.com/training/implementing-navigation/lateral.html
How can I Take listview with custom adapters and use in this example? I mean instead showing simple textview , display as.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip" >
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="true"
android:layout_marginRight="6dip"
android:contentDescription="TODO"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/firstLine"
android:layout_width="fill_parent"
android:layout_height="26dip"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_toRightOf="#id/icon"
android:ellipsize="marquee"
android:singleLine="true"
android:text="Description"
android:textSize="12sp" />
<TextView
android:id="#+id/secondLine"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#id/secondLine"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_alignWithParentIfMissing="true"
android:layout_toRightOf="#id/icon"
android:gravity="center_vertical"
android:text="Example application"
android:textSize="16sp" />
</RelativeLayout>
Result should be as Play store application.
Thanks.

Maybe this is what you are looking for:
How to use swipe gesture in a view pager's page with android?
Try these links..maybe this is what you are looking for.
Here's an Update
1) Make an Adapter to handle your fragments:
public class MyAdapter extends FragmentStatePagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new FirstFragment();
case 1:
return new SecondFragment();
case 2:
return new ThirdFragment();
}
return null;
}
#Override
public int getCount() {
return 3;
}
}
2) Add fragments: I am just adding the code for one fragment. You can follow that.
public class FirstFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.somefragment, container, false);//You will have your custom layout and add more items.
return view;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
TextView tv = (TextView)getActivity().findViewById(R.id.textview1);
//You can add different items in here according to your needs.
//You will have your own code to do stuff. Like to use a listview or a gridview etc. You will make a separate adapter in a separate class and use that adapter in this onActivityCreated() method.
}
}
3) Modify the MainActivity:
public class AllActivities extends FragmentActivity implements ActionBar.TabListener {
public ViewPager viewPager;
private MyAdapter mAdapter;
private ActionBar actionBar;
private String [] tabs = {"FirstFragment","SecondFragment","ThirdFragment"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Initializing all stuff
viewPager = (ViewPager)findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new MyAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(true);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
//Add the tabs here
for(String tab_name:tabs){
actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
}
viewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener(){
#Override
public void onPageSelected(int position){
//on Page change, that particular page should be selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0,float arg1,int arg2){
}
#Override
public void onPageScrollStateChanged(int position){
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction fragmentTransaction) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction fragmentTransaction) {
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction fragmentTransaction) {
viewPager.setCurrentItem(tab.getPosition());
}
}
After you have implemented this example, you don't have to worry about this MainActivity. All you have to add more fragments is that add fragments to your adapter and build pages according to that. Also, add private String [] tabs = {"FirstFragment","SecondFragment","ThirdFragment","You other fragments when you will define"};
To make google play like navigation drawer, you can refer to my first two links and make then work as you like.
Hope this one helps for what you were looking for.

You can do this:
yourButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
Intent intent = new Intent(getActivity(),NextActivity.class);
getActivity().startActivity(intent);
}
});
You just have to do your Intent.
this.getActivity.startActivity(this.getApplicationContext(), ClassName.class);

#Override
public int getCount() {

return 3;
}
}
nNot sure where i am going wrong.Any help is appreciated.
I had the same problem. I found the solution after a lot of searches. I would see 2 problems in your code: (sorry for my bad english)
1) to change an item inside the adapter (connected to your viewpager) for a given position, you have to change the items returned by the method public Fragment getItem(int index) and call the method notifyDataSetChanged() to notify to the adapter that the content is changed.
2) the implementation of the FragmentStatePagerAdapter contains a cache based on the position and it doesn't change even if you call the notifyDataSetChanged() and you return the PagerAdapter.POSITION_NONE (there is an issue reported here: https://code.google.com/p/android/issues/detail?id=37990)
what I would suggest you is:
use a FragmentPagerAdapter, implement properly the methods getItem(int index) (with the correct item at the given position), getItemPosition(Object object), and getItemId(int position)
if you want to use a FragmentStatePagerAdapter, consider the implementation suggested in the issue I liked above (NewFragmentStatePagerAdapter).
I hope it helps!

Source Not Found when using ListFragment & ViewPager

I've been trying to create a simple Horizontal scrolling option.
I have 2 ListFragments, which I would like to scroll between.
I'm getting a "Source Not Found" error when returning the View from onCreateView function.
This is my MainActivity Class:
public class MainActivity extends FragmentActivity implements ActionBar.TabListener {
AppSectionsPagerAdapter mAppSectionsPagerAdapter;
ViewPager mViewPager;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAppSectionsPagerAdapter = new AppSectionsPagerAdapter(getSupportFragmentManager());
final ActionBar actionBar = getActionBar();
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mAppSectionsPagerAdapter);
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
for (int i = 0; i < mAppSectionsPagerAdapter.getCount(); i++) {
actionBar.addTab(
actionBar.newTab()
.setText(mAppSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this));
}
}
#Override
public void onTabUnselected(ActionBar.Tab tab, android.app.FragmentTransaction fragmentTransaction) {
}
#Override
public void onTabSelected(ActionBar.Tab tab, android.app.FragmentTransaction fragmentTransaction) {
// When the given tab is selected, switch to the corresponding page in the ViewPager.
mViewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabReselected(ActionBar.Tab tab, android.app.FragmentTransaction fragmentTransaction) {
}
public static class AppSectionsPagerAdapter extends FragmentPagerAdapter {
public AppSectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
Fragment a;
#Override
public Fragment getItem(int i) {
switch (i) {
case 0:
return new FragmentA();
default:
return new FragmentB();
}
}
#Override
public int getCount() {
return 2;
}
#Override
public CharSequence getPageTitle(int position) {
return "Section " + (position + 1);
}
}
}
This is one of my ListFragment class (the second is the same but different name & layout file):
public class FragmentA extends ListFragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.favorites_layout, container, false);
updateStationsView(0);
return rootView;
}
}
updateStationView is a function that populates the List. removing it did not help, so I figured it's harmless.
The error is thrown right after the:
return rootView;
which returns to the onCreate functions of MainActivity.
When I'm changing the ListFragment to be a simple Fragment it works. I think I'm lacking some knowledge to figure this one out. I really want to use ListFragment...
Can someone please try an help ?
Many thanks for your efforts.
Adding the XML files:
activity_main.xml:
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
favorites_layout.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
I im quite sure the issue is that your custom layout for the ListFragment does not contain a ListView. These lines of code are causing the error because you need to have a ListView inside your "favourites_layout" .xml file.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.favorites_layout, container, false);
updateStationsView(0);
return rootView;
}
ListFragment has a default layout that consists of a single list view.
However, if you desire, you can customize the fragment layout by
returning your own view hierarchy from onCreateView(LayoutInflater,
ViewGroup, Bundle). To do this, your view hierarchy must contain a
ListView object with the id "#android:id/list" (or list if it's in
code)
So your layout could for example look like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>

Trouble with ViewPager displaying Fragments

I am trying to get a fragment with three tabs displayed using ViewPager. Initially I used to instantiate the fragment from the Activity using FragmentMgr, this worked fine. When I converted this navigation using ViewPager, this Fragment is no longer displayed.
MainActivity.java
When I initiate Fragment like this, it gets displayed. eg:
LaunchListFragment fragment = new LaunchListFragment();
fragment.newInstance(LIST_TYPE);
getSupportFragmentManager().beginTransaction()
.add(R.id.item_detail_container,
fragment).commit();
I tried this change above code to make use of ViewPager as follows:
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(new LaunchPageAdapter(getSupportFragmentManager(),LIST_TYPE));
mViewPager.setCurrentItem(0);
where LaunchPageAdapter calls LaunchListFragment.
LaunchPageAdapter.java
public class LaunchPageAdapter extends FragmentPagerAdapter {
private static String select="";
public LaunchPageAdapter(FragmentManager fm, String type) {
super(fm);
select=type;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return LaunchListFragment.newInstance(select);
case 1:
return AddTeamFragment.newInstance();
}
return null;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return 2;
}
Here is LaunchListFragment.java
public class LaunchListFragment extends ListFragment implements ActionBar.TabListener {
public static String LIST_TYPE = "invalid";
GenericListData g_data[] = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View result = inflater.inflate(R.layout.fragment_launch_list,
container, false);
setActionTabs();
setList();
return (result);
}
public static Fragment newInstance(String type) {
Fragment frag = new LaunchListFragment();
Bundle args = new Bundle();
LIST_TYPE=type;
args.putString(LIST_TYPE, type);
frag.setArguments(args);
return (frag);
}
This is main.xml layout used by MainActivity
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_marginTop="5dp"
android:gravity="center_vertical"
android:textColor="#000000"
android:textSize="22dp"
android:textStyle="bold" />
When I debug this, I can see LaunchListFragment is getting instantiated, onCreate and onCreate View is called, it just won't get displayed. :(
Can anyone here let me know if I am missing anything here in my ViewPager implementation?
Update
When I called LaunchListFragment without using Viewpager, I set the content view first and passed R.id.item_detail_container which is the id of the FrameLayout where I want the fragment to be displayed. Please refer to main.xml earlier
setContentView(R.layout.main.xml);
LaunchListFragment fragment = new LaunchListFragment();
fragment.newInstance(LIST_TYPE);
getSupportFragmentManager().beginTransaction()
.add(R.id.item_detail_container,
fragment).commit();
When I changed this to use ViewPager, I am not sure where I'm directing the Fragment to be displayed. In my fragment onView I'm inflating fragment_launch_list and returning the View. But how will the view pager know where to set the fragment view. Is it inside the id pager?
I'm an absolute beginner, I apologize if all these are naive questions.
Cheers.
The question description is perfectly suitable to the problem I just had. I know the question is old but may this help other who face same. #Geoplex have not shown code of LaunchPageAdapter class. So I'm not sure if this solves his problem or not. But for me that worked.
In my PagerAdapter, the
public boolean isViewFromObject(View view, Object object) was overridden. I removed that method and allowed superClass to handle it. That started giving my expected result.
This is useful for you,
public class ViewPagerAdapter extends FragmentStatePagerAdapter {
private List<Fragment> fragments=null;
