Hallo zussammen ich versuche verzweifelt eine Animation an laufen zu bekommen.
Hier ist ersteinmal die Animations klasse:
public class ZoomOutPageTranformer implements ViewPager.PageTransformer{
private static final float MIN_SCALE = 0.85f;
private static final float MIN_ALPHA = 0.5f;
public void transformPage(View view, float position) {
int pageWidth = view.getWidth();
int pageHeight = view.getHeight();
if (position < -1) { // [-Infinity,-1)
// This page is way off-screen to the left.
view.setAlpha(0);
} else if (position <= 1) { // [-1,1]
// Modify the default slide transition to shrink the page as well
float scaleFactor = Math.max(MIN_SCALE, 1 - Math.abs(position));
float vertMargin = pageHeight * (1 - scaleFactor) / 2;
float horzMargin = pageWidth * (1 - scaleFactor) / 2;
if (position < 0) {
view.setTranslationX(horzMargin - vertMargin / 2);
} else {
view.setTranslationX(-horzMargin + vertMargin / 2);
}
// Scale the page down (between MIN_SCALE and 1)
view.setScaleX(scaleFactor);
view.setScaleY(scaleFactor);
// Fade the page relative to its size.
view.setAlpha(MIN_ALPHA +
(scaleFactor - MIN_SCALE) /
(1 - MIN_SCALE) * (1 - MIN_ALPHA));
} else { // (1,+Infinity]
// This page is way off-screen to the right.
view.setAlpha(0);
}
}
}
Und hier ist meine MainActivity:
public class MainActivity extends FragmentActivity {
/**
* The number of pages.
*/
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_main);
mPager = (ViewPager) findViewById(R.id.pager);
mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
mPager.setAdapter(mPagerAdapter);
mPager.setPageTransformer(ture, new ZoomOutPageTranformer());
}
}
/**
* A simple pager adapter that represents 5 ScreenSlidePageFragment objects, in
* sequence.
*/
public class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
return new MainFragment();
}
@Override
public int getCount() {
return NUM_PAGES;
}
}
Und die dazu gehörige xml datei:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/container"
android:layout_width="match_parent" android:layout_height="match_parent"
tools:context=".MainActivity" tools:ignore="MergeRootFrame" >
<fragment android:name="de.nimaldev.fragments.MainFragment"
android:id="@+id/mainFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
so Und hier ist meine fragment Klasse:
public class MainFragment extends Fragment {
private Button webshop = (Button) getView().findViewById(R.id.button_webshop);
private Button aktion = (Button) getView().findViewById(R.id.button_aktionen);
private Button news = (Button) getView().findViewById(R.id.button_news);
private Button ueberUns = (Button) getView().findViewById(R.id.button_ueberUns);
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_main, container,false);
return rootView;
}
private void onClick(View v){
//TODO fragments + animation
if(v == webshop){
}
else if(v == aktion){
}
else if(v == news){
}
else if(v == ueberUns){
}
}
}
So jetzt zu meiner Frage wie bekomme ich es hin das die Animation durchgeführt wird so dass mein zweites Fragment erscheint..
Hier ist mein zweites Fragment:
public class SecondFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_second, container,false);
return rootView;
}
private void onClick(View v){
}
}
Ein Fehler ist kein Fehler es ist ein Feature///https://play.google.com/store/apps/developer?id=Nimal+Development
