增加动画的效果

a) alpha(AlphaAnimation)

渐变透明

b) scale(ScaleAnimation)

渐变尺寸伸缩

c) translate(TranslateAnimation)

画面转换、位置移动

d) rotate(RotateAnimation)

画面转移，旋转动画

public void onClick(View v) {
                if(grid_list) {
                    lv.setVisibility(View.VISIBLE);
                    gv.setVisibility(View.GONE);
                    lv.setAdapter(lvAdapter);
                    grid_list = false;
                    
                    Animation animation = new RotateAnimation(60,0);
                    animation.setInterpolator(MainActivity.this, android.R.anim.bounce_interpolator);
                    animation.setDuration(1000);
                    
                    lv.startAnimation(animation);
                }
                else {
                    lv.setVisibility(View.GONE);
                    gv.setVisibility(View.VISIBLE);
                    gv.setAdapter(gvAdapter);
                    grid_list = true;
                    Animation animation = new TranslateAnimation(130, 1, 130, 1);
                    animation.setDuration(1000);
                    animation.setInterpolator(MainActivity.this, android.R.anim.overshoot_interpolator);
                    //setInterpolator用来丰富动画效果，上面是超过又回来
                    gv.startAnimation(animation);
                }

 若想让一个VIEW呈现多种动画效果，则要使用AnimationSet

例如：

AnimationSet set = new AnimationSet(false);

set.addAnimation(animation);

VIEW.startAnimation(set);

可以理解为set是一种混合型的动画效果。
