Answer 1

复制代码
float fromXDelta = context.length;
        TranslateAnimation translateAnimation =null;
        if (this.context.oldTabViewIndex < this.context.curTabViewIndex) {
            fromXDelta = context.length * (this.context.curTabViewIndex - this.context.oldTabViewIndex);
            translateAnimation = new TranslateAnimation(0,
                    fromXDelta, 0.0F, 0.0F);
        }else {
            fromXDelta = context.length * (this.context.oldTabViewIndex - this.context.curTabViewIndex);
            translateAnimation = new TranslateAnimation(0,
                fromXDelta*-1, 0.0F, 0.0F);
        }
复制代码
复制代码
translateAnimation.setAnimationListener(new AnimationListener(){            @Override
            public void onAnimationEnd(Animation animation) {
                RelativeLayout.LayoutParams aLayoutParams = (RelativeLayout.LayoutParams) context.tab_front_bg
                    .getLayoutParams();
                aLayoutParams.setMargins(context.curTabViewIndex*context.length, 0, 0, 0);
                context.tab_front_bg.setLayoutParams(aLayoutParams);
//                context.tab_front_bg.clearAnimation();//解决移动后闪烁现象       ①
                TranslateAnimation anim = new TranslateAnimation(0,0,0,0);　　   ②
                context.tab_front_bg.setAnimation(anim);　　　　　　　　　　　　　　 ③
            }            @Override
            public void onAnimationRepeat(Animation animation) {
                // TODO Auto-generated method stub
                
            }            @Override 
            public void onAnimationStart(Animation animation) {
                
            }
        });
        translateAnimation.setDuration(200);
        context.tab_front_bg.startAnimation(translateAnimation);
复制代码如没有 ① ② ③ 代码，动画结束后停在动画结束的位置后闪烁一下，  加上①处代码  可以解决 不过Listview会有问题，  改用②③解决
