Android Pagerview Between Activities

Android PagerView between Activities

You can't use ViewPager to swipe between Activities. You need to convert each of you five Activities into Fragments, then combine everything in one FragmentActivity with the Adapter you use with ViewPager.

Here's a link that goes into detail on converting your current Activities info Fragments.

This is the Fragment topic on the Android Developers website, it has a lot of useful info.

Here's another example (full source) that inflates TextViews on each page.

Here's an example that I typed up:

PagerAdapter:

public class PagerAdapter extends FragmentPagerAdapter {

    private final List<Fragment> mFragments = new ArrayList<Fragment>();

    public PagerAdapter(FragmentManager manager) {
        super(manager);
    }

    public void addFragment(Fragment fragment) {
        mFragments.add(fragment);
        notifyDataSetChanged();
    }

    @Override
    public int getCount() {
        return mFragments.size();
    }

    @Override
    public Fragment getItem(int position) {
        return mFragments.get(position);
    }
}

This should be called in onCreate of your FragmentActivity:

    private void initPaging() {

    FragmentOne fragmentOne = new FragmentOne();
    FragmentTwo fragmentTwo= new FragmentTwo();

    PagerAdapter pagerAdapter = new PagerAdapter(getSupportFragmentManager());
    pagerAdapter.addFragment(fragmentOne);
    pagerAdapter.addFragment(fragmentTwo);

    ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
    viewPager.setAdapter(pagerAdapter);
}

This is an example of the layout you'd use for your FragmnetActivity:

<?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.view.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</LinearLayout>

To create Fragment create a new class that extends Fragment. The first two methods you'll want to override are onActivityCreated and onCreateView.

Here's how you could do that:

public class FragmentOne extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(THE_LAYOUT_FROM_YOUR_ORIGINAL_ACTIVITY, container, false);
    return view;
    }
}

Using ViewPager to open different activities

Inside your PlaceHolderFragment onCreateView() callback, you just have to check what image id you have on your Fragments argument. With that resource id, you can launch your Activity according to that value:

jeans.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {

        Intent activityIntent = new Intent();

        Intent intent = new Intent();

        switch(imagen){
        case R.drawable.jeans:
            intent = new Intent(getActivity(), JeansActivity.class);
            break;
        case R.drawable.blusas:
            intent = new Intent(getActivity(), BlusasActivity.class);
            break;
            R.drawable.leggings:
                intent = new Intent(getActivity(), LegginsActivity.class);
            break;
        }

        startActivity(intent);
    }
});

Start new activity from activity in viewpager?

Context https://developer.android.com/reference/android/content/Context.html. Here you can see why we use context.

Like this way you can call another activity.

public class CustomPagerAdapter extends Your_adapter_method {
 private Context context; 

 public CustomPagerAdapter(Context context) {
      this.context = context;     //Main Activity Context
 }

 public View getView(...){
     View v;
     v.setOnClickListener(new OnClickListener() {
         void onClick() {
              Intent intent= new Intent(context, secondactivity.class);
              intent.putextra("your_extra","your_class_value");
              context.startActivity(intent); //Must use context to start activity.
         }
     });
 }
}

Hope it helps.!

android - Pass data from Activity to Fragment in ViewPager

Okay, I did this.

1 step: I created public interface in my Activity and setter for it:

private OnAboutDataReceivedListener mAboutDataListener;

public interface OnAboutDataReceivedListener {
        void onDataReceived(AboutCompanyViewModel model);
    }

public void setAboutDataListener(OnAboutDataReceivedListener listener) {
    this.mAboutDataListener = listener;
}

2 step: I implemented this interface in my Fragment and set listener:

public class AboutCompanyFragment extends BaseFragment implements ManagementCompanyOverviewActivity.OnAboutDataReceivedListener

    @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            mActivity = (ManagementCompanyOverviewActivity) getActivity();
            mActivity.setAboutDataListener(this);
        }

3 step: I overrided interface's method:

@Override
    public void onDataReceived(AboutCompanyViewModel model) {
        mPBName.setVisibility(View.INVISIBLE);
        mPBDirector.setVisibility(View.INVISIBLE);
        mPBWebsite.setVisibility(View.INVISIBLE);
        mPBEmail.setVisibility(View.INVISIBLE);
        mPBPhone.setVisibility(View.INVISIBLE);
        mPBSchedule.setVisibility(View.INVISIBLE);
        mPBAddress.setVisibility(View.INVISIBLE);

        mTVName.setVisibility(View.VISIBLE);
        mTVDirector.setVisibility(View.VISIBLE);
        mTVWebsite.setVisibility(View.VISIBLE);
        mTVEmail.setVisibility(View.VISIBLE);
        mTVPhone.setVisibility(View.VISIBLE);
        mTVSchedule.setVisibility(View.VISIBLE);
        mTVAddress.setVisibility(View.VISIBLE);

        mTVName.setText(model.getCompanyName());
        mTVDirector.setText(model.getDirectorName());
        mTVWebsite.setText(model.getWebsite());
        mTVEmail.setText(model.getEmail());
        mTVPhone.setText(model.getPhone());
        mTVSchedule.setText(model.getWorkTime());
        mTVAddress.setText(model.getAddress());
    }

That's it.
