I've incuded in my app a viewpager which contains 3 fragements with 3 different layouts. Navigating on the net i found these really nice example, i want to add them to my fragments in order to offer a more intersting expercience to the user.
Github resource 1
Github resource 2
Unfortunely they are both compiled in grandle, but i'm working with eclpise. So, my first question is: is possible to "convert" these project and import them to eclipse? And the second: if not, can you give me a working example or a first point to start?
This is my Activity:
public class WelcomeScreen extends FragmentActivity{
List<Fragment> fragments = new Vector<Fragment>();
List<String> fragmentTitles = new Vector<String>();
private PagerAdapter mPagerAdapter;
private ViewPager mPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.welcomescreen);
fragments.add(Fragment.instantiate(this, welcome1.class.getName()));
fragmentTitles.add("Step 1");
fragments.add(Fragment.instantiate(this, welcome2.class.getName()));
fragmentTitles.add("Step 2");
fragments.add(Fragment.instantiate(this, welcome3.class.getName()));
fragmentTitles.add("Step 3");
this.mPagerAdapter = new PagerAdapter1(super.getSupportFragmentManager(),fragments,fragmentTitles);
mPager = (ViewPager) super.findViewById(R.id.pager);
View pagerStrip = findViewById(R.id.pagerTabStrip);
mPager.setAdapter(this.mPagerAdapter);
}
}
And this one of the fragments:
public class welcome1 extends Fragment {
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
if (container == null) {
return null;
}
// inflate view from layout
View view = (LinearLayout)inflater.inflate(R.layout.welcome1,container,false);
return view;
}
Thanks to all! :)
Hey~ I'm the author of the second repo you've mentioned above. ;-D
Though I've abandoned eclipse for years. I can definitely assure you that eclipse supports gradle projects as well as intellij-like IDE, such as android studio.
But ah ... given android studio is the officially recommended dev tool, why don't you use it? Or at least use the intellij community edition is much better than the clumsy eclipse.

so this one really has me stumped. I am trying to create a simple ViewPager activity which has three swipe views containing a listview. I have a FragmentPagerAdapter, a ListFragment set to hold the listviews, and have defined the layout for the fragments. Here is my problem is that FragmentPagerAdapter takes a FragmentManager, so I try to pass it in like so
mFragmentPagerAdapter=new FragmentPagerAdapter(getSupportFragmentManager());
but the FragmentManager is always null, meaning that the rest of the work to set up the pager crashes the app
I have no idea why getSupportFragmentManager would return null.
Here is the code for my activity, or at least the relevant bits
public class JobListActivity extends FragmentActivity {
private ArrayList<Job> jobsQuote=new ArrayList<Job>();
private ArrayList<Job> jobsIn= new ArrayList<Job>();
private ArrayList<Job> jobsOut=new ArrayList<Job>();
private ListFragment quoteListFragment=new ListFragment();
private ListFragment inListFragment =new ListFragment();
private ListFragment outListFragment=new ListFragment();
JobFragmentPagerAdapter mFragmentPagerAdapter;
ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_job_list);
FragmentManager fm = getSupportFragmentManager();
mFragmentPagerAdapter =
new JobFragmentPagerAdapter(fm);
mViewPager = (ViewPager) findViewById(R.id.jobs_view_pager);
mViewPager.setAdapter(mFragmentPagerAdapter);
I really appreciate any help you can provide, thanks so much for your time
Here is the tutorial I have been following from the android developer web site
http://developer.android.com/training/implementing-navigation/lateral.html
clearly I am missing something.
Figured it out. When I implement the methods from Fragment activity, I accidentily overrode getSupportFragmentManager(); to return null.
I am trying to make an activity have swipable tabs, with each tab having a different fragment (I dont know yet how many fragments I am going to have, so assume they will be at least 5).
So I am having problems make the parent activity with the tabs (if I said that correctly) and then the fragments themselves have some dynamically added views (text views and one image view) which get their stuff from different async tasks, executed when the fragment is showed.
Don't know if I explained it correctly, but here is my code and I'll ask you please to add in it the needed stuff.
So here is the parrent activity which must host the tabs and the fragments:
public class SecondActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
}
}
and here is one of the fragments (the others are similar):
public class Fragment1 extends Fragment {
LinearLayout layout;
ImageView iv;
String anotherURL;
ArrayList<InfoStuff> ci;
public Fragment1() {
// Empty constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment1, container, false);
layout = (LinearLayout) rootView.findViewById(R.id.layout);
iv = (ImageView) rootView.findViewById(R.id.ivPortrait);
Bundle b = this.getArguments();
ci = b.getParcelableArrayList("infoStuff");
regionUrl = b.getString("someURL");
createViews();
return rootView;
}
public void createViews() {
TextView tv;
tv = new TextView(v.getContext());
tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
tv.setText("le text");
layout.addView(tv);
tv = new TextView(v.getContext());
tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
tv.setText("some text");
layout.addView(tv);
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(v.getApplicationContext()).build();
ImageLoader.getInstance().init(config);
String imgUrl = "someURL";
ImageLoader.getInstance().displayImage(imgUrl, iv);
}
}
I am also having troubles making the ImageView work, as it is from an additional library (forgot the name, heres the import though import com.nostra13.universalimageloader.core.ImageLoader;)
EDIT: Sorry, forgot to mention the tabs must be swipeable
The article Creating Navigation tabs using TabHost and Fragments in Android may help you.
In this article, we will develop an Android application containing navigation tabs. There are many ways by which we can add navigation tabs to an application.
Beginning with Android 3.0, the standard way to create navigation tab is using action bar. [...]
For Android 2.x and above, we can use Action bar Sherlock library to create navigation library. [...]
In this application, we are creating navigation tabs using TabHost and Fragments. [...]
This application is developed in Eclipse 3.7.2 with ADT plugin (20.0.2) and Android SDK ( R20.0.1 ) .
I just started doing something very similar to what you want to do. I followed this tutorial on Android Hive, which was very helpful in getting the tabs, swiping, and fragments down. (The fragments in this example are just textviews with different colors, but you can easily figure out where to add in your own views).
Hope this helps - it did for me!
I'm looking for some ideas on how to do a simple listview with images while inside a SherlockFragment class; Which is then loaded into a ViewPager fragment. I've tried several examples listed below, each one I cannot get to successfully work. I'm not asking for someone to do it for me, I'm looking for advice on how to build one from someones experience to direct me for resources.
Examples i have tried
android fragment example
android sdk fragments
I assume that the listview with images is no problem.
To show fragments in a viewpager you should work with the support-library and go like this:
you create a layout with a viewpager:
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
create a fragment that inflates your layout in 1., your on onCreateView Method should conatin the following lines:
View v = inflater.inflate(R.layout.view_pager_layout, parent, false);
MyFragmentAdapter mMyPagerAdapter =
new MyFragmentAdapter (getChildFragmentManager());
// ... set data to pager
mMyPagerAdapter.setCountOfFragments(mCountOfFragments);
mViewPager = (ViewPager) v.findViewById(R.id.view_pager);
mViewPager.setAdapter(mMyPagerAdapter);
3.create a class that extends from FragmentStatePagerAdapter. This should look like this:
public class MyFragmentAdapter extends FragmentStatePagerAdapter{
public MyFragmentAdapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
}
#Override
public Fragment getItem(int position) {
// create here you listfragment that should be shown in your viewPager
Fragment fragment = new ...;
// you also can set data to this listFragment
Bundle bundle = new Bundle();
fragment.setArguments(bundle);
return fragment;
}
#Override
public int getCount() {
return mCountOfFragments;
}
}
These Links were helpfull for me:
http://developer.android.com/training/animation/screen-slide.html
http://developer.android.com/reference/android/support/v4/view/ViewPager.html
And also the sample of effectivenavigation (https://android.googlesource.com/platform/development/+/d80ee02/samples/training/EffectiveNavigation) is really helpful.
In my application i have a tabhost with a tabwidget that have several Tabs.
Now i need a tab that show me inside the tabcontent a schedule grid that allow swipe to right and left to move through the months. But i need that the tab stay fixes and only the schedule swipes.
The navigation type (Fixed tabs + Swipe) allow me that? From what I understand this navigation allow the swipe but the tab don't stay the same.
What i need is possible?
Thanks for your help and attention.
I would say possible, stay with your codes on tabhost and tabwidget.
So I would assume one of those tabs are calling an Activity which probably named Schedule.class, by default tabhost does not allow any swiping to change tab feature, that is fine.
So in your Schedule Activity, you would be using ViewPager, I learnt how to use it from this article: http://thepseudocoder.wordpress.com/2011/10/05/android-page-swiping-using-viewpager/
Which is pretty easy to be understood. You may try to use it, hope I answered your question
Update: Here's a sample
Schedule.class
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.schedule);
ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
List<Fragment> fragments = new ArrayList<Fragment>();
fragments.add(Fragment.instantiate(this, Fragment1.class.getName()));
fragments.add(Fragment.instantiate(this, Fragment2.class.getName()));
fragments.add(Fragment.instantiate(this, Fragment3.class.getName()));
MyFragmentAdapter miscFragmentAdapter = new MyFragmentAdapter(getSupportFragmentManager(), fragments);
viewPager.setAdapter(miscFragmentAdapter);
}
MyFragmentAdapter.class
public class MyFragmentAdapter extends FragmentPagerAdapter {
private List<Fragment> fragments;
public MiscFragmentAdapter(FragmentManager fragmentManager, List<Fragment> fragments) {
super(fragmentManager);
this.fragments = fragments;
}
#Override
public Fragment getItem(int position) {
return this.fragments.get(position);
}
#Override
public int getCount() {
return this.fragments.size();
}
}
schedule.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<android.support.v4.view.ViewPager
android:id="#+id/viewPager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
Fragment1.class or Fragment2.class or Fragment3.class
public class Fragment1 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (container == null) {
// We have different layouts, and in one of them this
// fragment's containing frame doesn't exist. The fragment
// may still be created from its saved state, but there is
// no reason to try to create its view hierarchy because it
// won't be displayed. Note this is not needed -- we could
// just run the code below, where we would create and return
// the view hierarchy; it would just never be used.
return null;
}
return (LinearLayout) inflater.inflate(R.layout.fragment1, container, false);
}
}
fragment1 is a simple layout with whatever you want inside it.

Is there any help, resources, example or a tutorial available for putting fragments inside a fragment?
I have two tabs put up using Action Bar Navigation tabs, which essentially are fragments. What I want to do is, put in a ListFragment and a DialogFragment (to display a view with details) in one of those Action Bar Navigation tabs fragment.
Possible?? Please help. Thanks
Here's what I have done till now:
Followed Android's article on implementing navigation tabs on Action Bar and implemented a two tab action bar, this is running fine and I am able to show two different layouts.
In one of these tabs, I want to show a Fragmented view, for this I have created a FragmentList class with custom ArrayAdapter and data items, the data detail layout and class.
I am now stuck on how to display the fragments inside the tab. Following is the code which shows the content of first tab, how can I modify it to initialize the list fragment properly?
.
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View viewer = (View) inflater.inflate(R.layout.doodle_list, container,false);
return viewer;
}
Is there any help, resources, example or a tutorial available for putting fragments inside a fragment?
Fragments inside of fragments is not supported.
Fragments inside of fragments is supported on Android 4.2+ and via the Android Support package's backport of fragments. I'd still look to avoid it where possible.
I have two tabs put up using Action Bar Navigation tabs, which essentially are fragments.
You chose to do that. There is nothing about action bar tabs that requires the use of fragments.
I solved this problem. You can use Support library and ViewPager. If you don't need swiping by gesture you can disable swiping. So here is some code to improve my solution:
public class TestFragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.frag, container, false);
final ArrayList<Fragment> list = new ArrayList<Fragment>();
list.add(new TrFrag());
list.add(new TrFrag());
list.add(new TrFrag());
ViewPager pager = (ViewPager) v.findViewById(R.id.pager);
pager.setAdapter(new FragmentPagerAdapter(getActivity().getSupportFragmentManager()) {
#Override
public Fragment getItem(int i) {
return list.get(i);
}
#Override
public int getCount() {
return list.size();
}
});
return v;
}
}
P.S.It is ugly code for test, but it improves that it is possible.
