My new project consists of a Navigation Drawer with 6 fragments ( Audi / BMW / KIA... car brads ). I want each Fragment to have 2 other fragments ( Models, which will have a ListView with car models and the second fragment, called Pictures, it's obvious what that contains). I don't like tabs, that's why I chose TitleStrip with swipe navigation between the fragments.
BMW.java
public class BMW extends Fragment {
CollectionPagerAdapter mCollectionPagerAdapter;
ViewPager mViewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(com.zenyt.R.layout.fragment_bmw, container, false);
mCollectionPagerAdapter = new CollectionPagerAdapter(
getFragmentManager());
// Set up action bar.
final ActionBar actionBar = getActivity().getActionBar();
// Specify that the Home button should show an "Up" caret, indicating
// that touching the
// button will take the user one step up in the application's hierarchy.
actionBar.setDisplayHomeAsUpEnabled(true);
// Set up the ViewPager, attaching the adapter.
mViewPager = (ViewPager) rootView.findViewById(R.id.bmw_pager);
mViewPager.setAdapter(mCollectionPagerAdapter);
return rootView;
}
public class CollectionPagerAdapter extends FragmentStatePagerAdapter {
final int NUM_ITEMS = 2; // number of tabs
public CollectionPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int i) {
Fragment fragment = new TabFragment();
Bundle args = new Bundle();
args.putInt(TabFragment.ARG_OBJECT, i);
fragment.setArguments(args);
return fragment;
}
#Override
public int getCount() {
return NUM_ITEMS;
}
#Override
public CharSequence getPageTitle(int position) {
String tabLabel = null;
switch (position) {
case 0:
tabLabel = getString(R.string.label1);
break;
case 1:
tabLabel = getString(R.string.label2);
break;
}
return tabLabel;
}
}
public static class TabFragment extends Fragment {
public static final String ARG_OBJECT = "object";
private ListView myListView;
private String[] strListView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Bundle args = getArguments();
int position = args.getInt(ARG_OBJECT);
int tabLayout = 0;
switch (position) {
case 0:
tabLayout = R.layout.models;
break;
case 1:
tabLayout = R.layout.pictures;
break;
}
View rootView = inflater.inflate(tabLayout, container, false);
return rootView;
}
}
}
In TabFragment, I want fragments instead of layouts (models and pictures). How can I do that?
models.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tab1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#android:color/black"
>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/listView2" />
</RelativeLayout>
Models.java
public class Models extends Fragment {
private ListView myListView;
private String[] strListView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(com.zenyt.R.layout.models, container, false);
myListView = (ListView) rootView.findViewById(com.zenyt.R.id.listView2);
strListView = getResources().getStringArray(com.zenyt.R.array.bmw_list_data);
ArrayAdapter<String> objAdapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1, strListView);
myListView.setAdapter(objAdapter);
myListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
return rootView;
}
}
Seems that I solved it by myself. All I had to do was to change a bit the PagerAdapter, like this:
public class CollectionPagerAdapter extends FragmentStatePagerAdapter {
public CollectionPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int arg0) {
// TODO Auto-generated method stub
switch (arg0) {
case 0:
return new Bmw1();
case 1:
return new Bmw2();
default:
break;
}
return null;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return 2;
}
#Override
public CharSequence getPageTitle(int position) {
String tabLabel = null;
switch (position) {
case 0:
tabLabel = getString(R.string.label1);
break;
case 1:
tabLabel = getString(R.string.label2);
break;
}
return tabLabel;
}
}

I have created an android app in which I have added an activity called profileview.java on which users can view there or other user's profile data. Profileview activity contains two fragments post and likes on which I have to show the post that is been posted by the user and the post liked by the user but not getting any idea how to send the userid from the profileview activity to the other two fragments.
profileviewactivity.class
public class profileviewActivity extends AppCompatActivity {
public String userid;
private ViewPager viewPager;
private TabLayout tabLayout;
private settingtabAdopter Tabadapter;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profileview);
viewPager = (ViewPager) findViewById(R.id.viewpager);
Tabadapter = new settingtabAdopter(getSupportFragmentManager());
viewPager.setAdapter(Tabadapter);
tabLayout = (TabLayout) findViewById(R.id.tablayout);
tabLayout.setupWithViewPager(viewPager);
userid = getIntent().getExtras().get("userid").toString();
}
}
settingadapter.java
public class settingtabAdopter extends FragmentPagerAdapter {
public settingtabAdopter(#NonNull FragmentManager fm) {
super(fm);
}
#NonNull
#Override
public Fragment getItem(int position) {
switch (position){
case 0:
posttimeline postfragment = new posttimeline();
return postfragment;
case 1:
like chatfragment = new like();
return chatfragment;
default:
return null;
}
}
#Override
public int getCount() {
return 2;
}
#Nullable
#Override
public CharSequence getPageTitle(int i) {
switch (i){
case 0:
return "Posts";
case 1:
return "Likes";
default:
return null;
}
}
}
posttimeline.java
public class posttimeline extends Fragment {
View posttimelineview;
public posttimeline() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
posttimelineview = inflater.inflate(R.layout.fragment_posttimeline, container, false);
return posttimelineview;
}
}
like.java
public class like extends Fragment {
View Likeview;
public like() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
Likeview = inflater.inflate(R.layout.fragment_like, container, false);
return Likeview;
}
}
i want to send userid from the profileaviewactivity to the posttimeline and like fragment.
pass userid as parameter at settingtabAdopter constructor
public settingtabAdopter(#NonNull FragmentManager fm, String userid)
profileviewActivity -> onCreate
Tabadapter = new settingtabAdopter(getSupportFragmentManager(), userid);
make private variable inside settingtabAdopter
private String userid;
initialize it inside constructor
this.userid = userid
Create private variable in each fragment and add setter (posttimeline and like) fragments
private String mUserid;
void setMUserId(String mUserid){
this.mUserid = mUserid;
}
On settingtabAdopter inside getItem function after initialize each fragment set the private varaible with the userid
public Fragment getItem(int position) {
switch (position){
case 0:
posttimeline postfragment = new posttimeline();
postfragment.setMUserId(userid)
return postfragment;
case 1:
like chatfragment = new like();
chatfragment.setMUserId(userid)
return chatfragment;
default:
return null;
}
}

Had to add a framelayout at the end of the layout code for the fragment I was replacing:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/send1frameLayoutId">
</FrameLayout>
Then used this code to switch to a fragment in the same tab of the previous fragment:
Fragment send2 = new Send2();
FragmentManager fragmentManager = getChildFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.send1frameLayoutId, send2);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
First. Sorry for my English.
I have Activity class with ViewPager as a field and a Fragment class. My activity is a host for a fragment. In Fragment I want to call context menu registered for ImageView. For that, I override 2 methods: onCreateContextMenu and onContextItemSelected.
Problem is:
When onCreateContextMenu is called I get the correct page (that
on the screen now).
But when onContextItemSelected is called I get another page (this
depend on what parameter is set in
ViewPager.setOffscreenPageLimit(int)). For example, if it set 3, the returned page will be those, that on 3 positions to the left or to the right from current that on the screen.
How can I fix it?
Thank you.

setContentView(mViewPager);

}
#Override

return mCrimes.size();
}
});
UUID crimeId = (UUID) getIntent().getSerializableExtra(CrimeFragment.EXTRA_CRIME_ID);
for (int i = 0; i< mCrimes.size(); i++){
if (mCrimes.get(i).getId().equals(crimeId)){
mViewPager.setCurrentItem(i);
break;
}
}
}
}
and fragment code
public class CrimeFragment extends Fragment {
.......
private ImageView mPhotoView;
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
........
View v = inflater.inflate(R.layout.fragment_crime, container, false);
mPhotoView = (ImageView) v.findViewById(R.id.crime_imageView);
registerForContextMenu(mPhotoView);
return v;
}
.........
#Override

Log.i(TAG, mCrime.getTitle());
switch (v.getId()) {
case R.id.crime_imageView:
if (mCrime.getPhoto() != null)
getActivity().getMenuInflater().inflate(R.menu.crime_photo_context, menu);
break;
}
}
#Override

return true;
}
return super.onContextItemSelected(item);

ViewPager.setOffscreenPageLimit(int);
This will prepare the pages at both sides to the left and right (neighbours).
By default it is 1.
So, in your case to get the current fragment created by the viewPager.
You can store the fragments when created in an SparseArray by overriding the instantiateItem() and destroyItem() callback of viewPager with position.
private SparseArray<Fragment> registeredFragments = new SparseArray<Fragment>();
#Override
public Object instantiateItem(ViewGroup container, int position) {
Fragment fragment = (Fragment) super.instantiateItem(container, position);
registeredFragments.put(position, fragment);
return fragment;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
registeredFragments.remove(position);
super.destroyItem(container, position, object);
}
public Fragment getFragment(int position) {
return registeredFragments.get(position);
}
And where you want to get the current fragment, get it by using the getFragment() method by passing the position.
I have 3 activities:
1. The list of categories;
2. The news in this category;
3. Details about News
see the images below!
I implemented back button from the third activity to the second by setting the second activity as the parent activity for the third activity in the android manifest file, but it can not see the category that is chosen in the first activity so it doesn't display the list and crash, can anybody help me implementing back button?

When you specify parent activity in manifest for Up Navigation like this:
android:parentActivityName
and when you click on Up button in action bar, the parent activity gets restarted (in your case it is category activity), instead to avoid activity get restarted. just finish the top activity by putting this code in your 3rd activity (i.e Details about News).
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// Respond to the action bar's Up/Home button
case android.R.id.home:
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
and remove the parentActivityName from manifest.

Android Developers site really has very good explanation of ViewPager. You should check it out:
http://developer.android.com/training/animation/screen-slide.html
Here is an example I wrote:
activity_screen_slide.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" />
Java Code:
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
...
public class ScreenSlidePagerActivity extends FragmentActivity {
private static final int NUM_PAGES = 2;
private ViewPager mPager;
private PagerAdapter mPagerAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_screen_slide);
mPager = (ViewPager) findViewById(R.id.pager);
mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
mPager.setAdapter(mPagerAdapter);
}
#Override
public void onBackPressed() {
if (mPager.getCurrentItem() == 0) {
super.onBackPressed();
} else {
mPager.setCurrentItem(mPager.getCurrentItem() - 1);
}
}
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
//Create these fragments with your preferable names
switch (position) {
case 0:
return new ScreenSlidePageFragment();
case 1:
return new ScreenSlidePageFragment2();
default:
break;
}
}
#Override
public int getCount() {
return NUM_PAGES;
}
}
}
And here is one of your views that should look like it where fragment_ screen_slide_page is one of your layouts:
import android.support.v4.app.Fragment;
...
public class ScreenSlidePageFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_screen_slide_page, container, false);
return rootView;
}
}
You should really read the android developers site for further details.
You can return different fragments like this:
#Override
public Fragment getItem(int position) {
if (position == 0) {
return PlaceholderFragment.newInstance(position + 1);
} else {
return anotherFragment.newInstance();
}
}
If you want to use the same Fragment, you can change the content depending on the position you are passing to the fragment.
