andrid平移动画俩动画切花会卡一下

img_ayout_1和img_ayout_2是俩布局

    public Runnable runnable = new Runnable() {
        @Override
        public void run() {
            // TODO Auto-generated method stub
            //俩个动画
            AnimationSet animationSet1 = new AnimationSet(true);
            AnimationSet animationSet2 = new AnimationSet(true);
            //设置imageView2 为可见
            img_ayout_2.setVisibility(0);
            TranslateAnimation ta = new TranslateAnimation(
                    Animation.RELATIVE_TO_SELF, -1f, 
                    Animation.RELATIVE_TO_SELF,0f,
                    Animation.RELATIVE_TO_SELF, 0f,
                    Animation.RELATIVE_TO_SELF, 0f);
            //设置动画持续时间
            ta.setDuration(10000);
            //放入动画
            animationSet1.addAnimation(ta);
            //动画充满
            animationSet1.setFillAfter(true);

            ta = new TranslateAnimation(
                    Animation.RELATIVE_TO_SELF,0f,
                    Animation.RELATIVE_TO_SELF, 1.0f,
                    Animation.RELATIVE_TO_SELF,0f, 
                    Animation.RELATIVE_TO_SELF, 0f);
            ta.setDuration(10000);
            animationSet2.addAnimation(ta);
            animationSet2.setFillAfter(true);
            // 开始执行 

                img_ayout_1.startAnimation(animationSet1);
                img_ayout_2.startAnimation(animationSet2);


            if (juage){

                handler.postDelayed(runnable,8000); 
                }
            }
    };

调用：handler.postDelayed(runnable, 0);

问题：在切换下一轮动画的时候俩布局间距会变大

布局：

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:layout_weight="0.14"
        android:orientation="vertical" >

         <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:orientation="vertical" 
          android:id="@+id/img_Layout_1"
        >
        <ImageView

            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/line1" />

        <ImageView

            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
