Önceki cevaplara dayanarak, bunu doğru ve en net bir şekilde başarmak için aşağıdaki sınıfı yaptım (umarım):
public class MyViewPagerAdapter extends PagerAdapter {
ArrayList<ViewGroup> views;
LayoutInflater inflater;
public MyViewPagerAdapter(ActionBarActivity ctx){
inflater = LayoutInflater.from(ctx);
//instantiate your views list
views = new ArrayList<ViewGroup>(5);
}
/**
* To be called by onStop
* Clean the memory
*/
public void release(){
views.clear();
views = null;
}
/**
* Return the number of views available.
*/
@Override
public int getCount() {
return 5;
}
/**
* Create the page for the given position. The adapter is responsible
* for adding the view to the container given here, although it only
* must ensure this is done by the time it returns from
* {@link #finishUpdate(ViewGroup)}.
*
* @param container The containing View in which the page will be shown.
* @param position The page position to be instantiated.
* @return Returns an Object representing the new page. This does not
* need to be a View, but can be some other container of
* the page. ,container
*/
public Object instantiateItem(ViewGroup container, int position) {
ViewGroup currentView;
Log.e("MyViewPagerAdapter", "instantiateItem for " + position);
if(views.size()>position&&views.get(position) != null){
Log.e("MyViewPagerAdapter",
"instantiateItem views.get(position) " +
views.get(position));
currentView = views.get(position);
}
else{
Log.e("MyViewPagerAdapter", "instantiateItem need to create the View");
int rootLayout = R.layout.view_screen;
currentView = (ViewGroup) inflater.inflate(rootLayout, container, false);
((TextView)currentView.findViewById(R.id.txvTitle)).setText("My Views " + position);
((TextView)currentView.findViewById(R.id.btnButton)).setText("Button");
((ImageView)currentView.findViewById(R.id.imvPicture)).setBackgroundColor(0xFF00FF00);
}
container.addView(currentView);
return currentView;
}
/**
* Remove a page for the given position. The adapter is responsible
* for removing the view from its container, although it only must ensure
* this is done by the time it returns from {@link #finishUpdate(ViewGroup)}.
*
* @param container The containing View from which the page will be removed.
* @param position The page position to be removed.
* @param object The same object that was returned by
* {@link #instantiateItem(View, int)}.
*/
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View)object);
}
/**
* Determines whether a page View is associated with a specific key object
* as returned by {@link #instantiateItem(ViewGroup, int)}. This method is
* required for a PagerAdapter to function properly.
*
* @param view Page View to check for association with <code>object</code>
* @param object Object to check for association with <code>view</code>
* @return true if <code>view</code> is associated with the key object <code>object</code>
*/
@Override
public boolean isViewFromObject(View view, Object object) {
return view==((View)object);
}
}
Ve bunu aktivitenizde ayarlamalısınız:
public class ActivityWithViewsPaged extends ActionBarActivity {
/**
* The page Adapter: Manage the list of views (in fact here, its fragments)
* And send them to the ViewPager
*/
private MyViewPagerAdapter pagerAdapter;
/**
* The ViewPager is a ViewGroup that manage the swipe from left
* to right to left.
* Like a listView with a gesture listener...
*/
private ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_with_views);
// Find the viewPager
viewPager = (ViewPager) super.findViewById(R.id.viewpager);
// Instantiate the PageAdapter
pagerAdapter = new MyViewPagerAdapter(this);
// Affectation de l'adapter au ViewPager
viewPager.setAdapter(pagerAdapter);
viewPager.setClipToPadding(false);
viewPager.setPageMargin(12);
// Add animation when the page are swiped
// this instanciation only works with honeyComb and more
// if you want it all version use AnimatorProxy of the nineoldAndroid lib
//@see:http://stackoverflow.com/questions/15767729/backwards-compatible-pagetransformer
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){
viewPager.setPageTransformer(true, new PageTransformer());
}
}
@Override
protected void onStop() {
super.onStop();
pagerAdapter.release();
}
XML dosyalarının bariz view_screen.xml olduğu yerlerde:
<xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/screen"

<TextView

android:layout_width="wrap_content"
android:layout_gravity="center"

<ImageView

</LinearLayout>
Ve ActivtyMain aşağıdaki düzene sahiptir:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="24dp"
android:paddingRight="24dp"
android:id="@+id/viewpager"
android:background="#FF00F0F0">
</android.support.v4.view.ViewPager>
Cevabınız için Brian ve Nicholas'a çok teşekkür ederim, umarım bazı açık bilgiler eklerim ve bu özellik için bazı iyi uygulamaları öne çıkarırım.
