viewpager scrollview funktioniert nicht android

Question

Ich bin ViewPager und ScrollView auf Android integrieren, aber es scheint nicht zu funktionieren. Die ViewPager Scroll funktioniert gut, aber die ScrollView funktioniert überhaupt nicht auf alle Lösungen, die ich ausprobiert habe. Im Folgenden finden Sie meine MainActivity-Klasse und das XML-Layout.

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.navigation_drawer); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    hostDescription = (TextView) findViewById(R.id.host_description); 
    hostDescription.setTypeface(quickSandRegular); 
    hostDescription.setTextColor(Color.BLACK); 

    scrollView = (ScrollView) findViewById(R.id.scroll); 

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
    navigationView.setNavigationItemSelectedListener(this); 
    View header=navigationView.getHeaderView(0); 

    ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager); 
    ImageAdapter adapter = new ImageAdapter(); 
    viewPager.setAdapter(adapter); 

    // set navigation font 
    Menu m = navigationView.getMenu(); 
    for (int i=0;i<m.size();i++) { 
     MenuItem mi = m.getItem(i); 

     // apply font to subment 
     SubMenu subMenu = mi.getSubMenu(); 
     if (subMenu!=null && subMenu.size() >0) { 
      for (int j=0; j <subMenu.size();j++) { 
       MenuItem subMenuItem = subMenu.getItem(j); 
       applyFontToMenuItem(subMenuItem); 
      } 
     } 

     applyFontToMenuItem(mi); 
    } 

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) 
        .setAction("Action", null).show(); 
     } 
    }); 

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
      this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
    drawer.setDrawerListener(toggle); 
    toggle.syncState(); 

}

Answer 1

Sie müssen ViewPager.OnPageChangeListener implementieren und Ihre Logik schreiben in onPageScrollStateChanged

@Override 
     public void onPageScrollStateChanged(int state) { 
     ScrollView.requestDisallowInterceptTouchEvent(!(!lastPage && state == ViewPager.SCROLL_STATE_IDLE)); 
} 

Sie müssen Logik schreiben, um zu finden, ob Sie auf der letzten Seite sind oder nicht, was einfach ist.

Answer 2

Das Problem wurde behoben, indem die layout_height des ViewPagers angepasst wurde. Unten ist der Code:

<android.support.v4.view.ViewPager 
    android:id="@+id/view_pager2" 
    android:layout_width="match_parent" 
    android:layout_height="300dp" 
    android:paddingLeft="20dp" 
    android:paddingRight="20dp"/> 

ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager); 
     ImageAdapter adapter = new ImageAdapter(); 
     viewPager.setAdapter(adapter); 
     viewPager.setClipToPadding(false); 
     viewPager.setPadding(70, 0, 70, 0); 

class ImageAdapter extends PagerAdapter { 

     @Override 
     public int getCount() { 
      return IMAGES.length; 
     } 

     @Override 
     public boolean isViewFromObject(View view, Object object) { 
      return view == ((ImageView) object); 
     } 

     @Override 
     public Object instantiateItem(ViewGroup container, int position) { 
      ImageView imageView = new ImageView(getApplicationContext()); 
      imageView.setImageResource(IMAGES[position]); 
      ((ViewPager) container).addView(imageView, 0); 
      return imageView; 
     } 

     @Override 
     public void destroyItem(ViewGroup container, int position, Object object) { 
      ((ViewPager) container).removeView((ImageView) object); 
     } 

     @Override 
     public void setPrimaryItem(ViewGroup container, int position, Object object) { 
      setPrimaryItem((View) container, position, object); 
      // lastPage = IMAGES[position]==object; 
     } 
    }
