tabhost實現滑動效果

Question

我試圖用這個解決方案： How to implement TabHost sliding effect?

，但沒有做任何事情，我的意思是一切保持不變。 我想實現很簡單：

我這裏包括代碼解決方案：

import android.view.View; 
    import android.view.animation.AccelerateInterpolator; 
    import android.view.animation.Animation; 
    import android.view.animation.TranslateAnimation; 
    import android.widget.TabHost; 
    import android.widget.TabHost.OnTabChangeListener; 

/** 
* A custom OnTabChangeListener that uses the TabHost its related to to fetch information about the current and previous 
* tabs. It uses this information to perform some custom animations that slide the tabs in and out from left and right. 
* 
* @author Daniel Kvist

*/ 
public class AnimatedTabHostListener implements OnTabChangeListener 
{ 

    private static final int ANIMATION_TIME = 240; 
    private TabHost tabHost; 
    private View previousView; 
    private View currentView; 
    private int currentTab; 

    /** 
    * Constructor that takes the TabHost as a parameter and sets previousView to the currentView at instantiation 
    * 
    * @param tabHost 
    */ 
    public AnimatedTabHostListener(TabHost tabHost) 
    { 
     this.tabHost = tabHost; 
     this.previousView = tabHost.getCurrentView(); 
    } 

    /** 
    * When tabs change we fetch the current view that we are animating to and animate it and the previous view in the 
    * appropriate directions. 
    */ 
    @Override 
    public void onTabChanged(String tabId) 
    { 

     currentView = tabHost.getCurrentView(); 
     if (tabHost.getCurrentTab() > currentTab) 
     { 
      previousView.setAnimation(outToLeftAnimation()); 
      currentView.setAnimation(inFromRightAnimation()); 
     } 
     else 
     { 
      previousView.setAnimation(outToRightAnimation()); 
      currentView.setAnimation(inFromLeftAnimation()); 
     } 
     previousView = currentView; 
     currentTab = tabHost.getCurrentTab(); 

    } 

    /** 
    * Custom animation that animates in from right 
    * 
    * @return Animation the Animation object 
    */ 
    private Animation inFromRightAnimation() 
    { 
     Animation inFromRight = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, 1.0f, Animation.RELATIVE_TO_PARENT, 0.0f, 
       Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f); 
     return setProperties(inFromRight); 
    } 

    /** 
    * Custom animation that animates out to the right 
    * 
    * @return Animation the Animation object 
    */ 
    private Animation outToRightAnimation() 
    { 
     Animation outToRight = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 1.0f, 
       Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f); 
     return setProperties(outToRight); 
    } 

    /** 
    * Custom animation that animates in from left 
    * 
    * @return Animation the Animation object 
    */ 
    private Animation inFromLeftAnimation() 
    { 
     Animation inFromLeft = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, -1.0f, Animation.RELATIVE_TO_PARENT, 0.0f, 
       Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f); 
     return setProperties(inFromLeft); 
    } 

    /** 
    * Custom animation that animates out to the left 
    * 
    * @return Animation the Animation object 
    */ 
    private Animation outToLeftAnimation() 
    { 
     Animation outtoLeft = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, -1.0f, 
       Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f); 
     return setProperties(outtoLeft); 
    } 

    /** 
    * Helper method that sets some common properties 
    * @param animation the animation to give common properties 
    * @return the animation with common properties 
    */ 
    private Animation setProperties(Animation animation) 
    { 
     animation.setDuration(ANIMATION_TIME); 
     animation.setInterpolator(new AccelerateInterpolator()); 
     return animation; 
    } 
} 

所以只需要創建一個AnimatedTabHostListener對象，並通過setOnTabChangedListener()方法
我調試和它交給tabHost監聽器的方法被稱爲...但我沒有看到任何動畫。它怎麼可能？

LinearLayout SwipableViewTabConntainer=(LinearLayout)findViewById(R.id.SwipableTabViewContainer); 
     ArrayList<String> titles=new ArrayList<String>(); 
     titles.add("One"); 
     titles.add("Two"); 
     titles.add("Three"); 
     titles.add("Four"); 
     titles.add("Five"); 


     ArrayList<Fragment> fragments=new ArrayList<Fragment>(); 
     for(int i=0;i<titles.size();i++) 
     { 
      fragments.add(new Dummyfragment(titles.get(i))); 
     } 

     SwipeTabView swipeTabView=new SwipeTabView(this,titles,fragments,getSupportFragmentManager()); 
     SwipableViewTabConntainer.addView(swipeTabView);

Java代碼的試試這個代碼

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    tools:context=".MainActivity"> 

    <LinearLayout 
     android:id="@+id/SwipableTabViewContainer" 
     android:layout_width="match_parent" 
     android:orientation="vertical" 
     android:layout_height="match_parent"> 

    </LinearLayout> 


</LinearLayout>
