Dies ist die AppPromopager.Here ich die ViewPager verwende.

• Ich dachte, mit Hilfe von viewpager kann ich in der Lage eine Swipe Ansicht zu erhalten. ViewPager was added in AppPromoPager.

• Ich habe einen AppPromoPager zu diesem layout_home.xml file.But bis jetzt habe ich nicht einen Schlag bekommen view.Anybody mich mit these.Thank Ihnen helfen können.

Answer 1

Was ich getan habe, ist in jedem Tabcontent, den Swipe-Listener implementieren. Implementieren Sie im Tabhost eine Swipe-Methode.

tabcontent

layout.setOnTouchListener(new OnTouchListener() { 
private PointerCoords mDownPos = new PointerCoords(); 
private PointerCoords mUpPos = new PointerCoords(); 

@Override 
public boolean onTouch(View arg0, MotionEvent event) { 
    switch (event.getAction()) { 
     case MotionEvent.ACTION_DOWN: { 
      event.getPointerCoords(0, mDownPos); 
      return true; 
     } 
     case MotionEvent.ACTION_UP: { 
      event.getPointerCoords(0, mUpPos); 
      float dx = mDownPos.x - mUpPos.x; 
      // Check for horizontal wipe 
      if (Math.abs(dx) > SWIPE_MIN_DISTANCE) { 
       if (dx > 0) { 
        mParent.swipe(DIRECTION_RIGHT); 
       } else { 
        mParent.swipe(DIRECTION_LEFT); 
       } 
       return true; 
      } 
     } 
    } 
    return false; 
} 
}); 


protected void swipe(int direction) { 
    int current = mTabHost.getCurrentTab(); 
    if (direction == DIRECTION_LEFT) { 
    int newTab = --current % mTabHost.getTabWidget().getTabCount(); 
    mTabHost.setCurrentTab((newTab < 0) ? mTabHost.getTabWidget().getTabCount()-1 : newTab); 
} 
else { 
    mTabHost.setCurrentTab(++current % mTabHost.getTabWidget().getTabCount()); 
} 
} 

Answer 2

hey sollten Sie dies tun, indem ActionBar Tabs + viewpager hier ist ein Tutorial, das Sie machen lassen, was Sie wollen. http://www.androidhive.info/2013/10/android-tab-layout-with-swipeable-views-1/

Answer 3

Besser die Scrollable Tabs verwenden, die eine Kombination von Swipe view pager with the action bar tabs verwendet.
