ViewFlipper的getDisplayedChild（）方法總是返回0

我有一個ListView，它包含位置0處的ViewFlipper。但我無法使用showNext或showPrevious它沒有任何作用。ViewFlipper的getDisplayedChild（）方法總是返回0

下面的代碼片段展示了我是多麼實例viewFlipper

  View view1 = inflater.inflate(R.layout.flipper, null); 
      viewFlipper=(ViewFlipper)view1.findViewById(R.id.flipper); 

      viewFlipper.addView(getChildView(v1,0),0); 
      viewFlipper.addView(getChildView(v2,1),1); 
      viewFlipper.addView(getChildView(v3,2),2); 
      viewFlipper.addView(getChildView(v4,3),3); 
      viewFlipper.addView(getChildView(v5,4),4); 

      viewFlipper.setOnTouchListener(new OnTouchListener() { 
       @Override 
       public boolean onTouch(final View view, final MotionEvent event) { 
        gdt.onTouchEvent(event); 
        return true; 
       } 
      });

這是觀點的鰭狀肢的方法getChildView

private View getChildView(View view,int index){ 
    LayoutInflater inflater = this.getLayoutInflater(); 

    view = inflater.inflate(R.layout.event_feed, null);  
    //Event Highlight 
    highlight=(LinearLayout)view.findViewById(R.id.highlight); 
    media_url_value=(ImageView)view.findViewById(R.id.slider_pic); 
    slider_pic1=(ImageView)view.findViewById(R.id.slider_i1); 
    slider_pic2=(ImageView)view.findViewById(R.id.slider_i2); 
    slider_pic3=(ImageView)view.findViewById(R.id.slider_i3); 
    slider_pic4=(ImageView)view.findViewById(R.id.slider_i4); 
    slider_pic5=(ImageView)view.findViewById(R.id.slider_i5); 
    title_value=(TextView)view.findViewById(R.id.slider_title); 
    info_value=(TextView)view.findViewById(R.id.slider_info); 
    event_date_value=(TextView)view.findViewById(R.id.slider_eventdate); 

    imageLoader.DisplayImage(media_url[index],EventList.this,media_url_value); 
    title_value.setText(title[index]); 

    if(info[index].length()>=120) 
     info_value.setText(info[index].substring(0,120)+"......"); 
    else 
     info_value.setText(info[index]); 

    event_date_value.setText(event_date[index]); 

    if(index==0){ 
     slider_pic1.setBackgroundResource(R.drawable.slider_hover); 
     slider_pic2.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic3.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic4.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic5.setBackgroundResource(R.drawable.slider_empty); 
    } 

    if(index==1){ 
     slider_pic1.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic2.setBackgroundResource(R.drawable.slider_hover); 
     slider_pic3.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic4.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic5.setBackgroundResource(R.drawable.slider_empty); 
    } 

    if(index==2){ 
     slider_pic1.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic2.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic3.setBackgroundResource(R.drawable.slider_hover); 
     slider_pic4.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic5.setBackgroundResource(R.drawable.slider_empty); 
    } 

    if(index==3){ 
     slider_pic1.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic2.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic3.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic4.setBackgroundResource(R.drawable.slider_hover); 
     slider_pic5.setBackgroundResource(R.drawable.slider_empty); 
    } 

    if(index==4){ 
     slider_pic1.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic2.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic3.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic4.setBackgroundResource(R.drawable.slider_empty); 
     slider_pic5.setBackgroundResource(R.drawable.slider_hover); 
    } 

    return view; 
}

getDisplayedChild（）總是返回0，雖然它是視圖之間翻轉。

任何幫助將不勝感激... :)

您是否嘗試過清理項目（Eclipse的>項目 - >清潔..）？有時它是R.java導致這個問題。
