动画集合后, 记住页面

public class FragmentThree extends Fragment {

    private SharedPreferences.Editor editor;
    private SharedPreferences preferences;
    Handler handler = new Handler();

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        ImageView iv = view.findViewById(R.id.iv);

        // 动画集合
        AnimationSet animationSet = new AnimationSet(true);
        // 透明度
        AlphaAnimation alphaAnimation = new AlphaAnimation(1f, 0.2f);
        animationSet.addAnimation(alphaAnimation);

        // 缩放
        ScaleAnimation scaleAnimation = new ScaleAnimation(1f, 2f, 1f, 0.5f);
        animationSet.addAnimation(scaleAnimation);

        // 旋转
        RotateAnimation rotateAnimation = new RotateAnimation(0f, 90f, 0.5f, 0.5f);
        animationSet.addAnimation(rotateAnimation);

        // 设置动画时间
        animationSet.setDuration(3000);
        animationSet.setFillAfter(true);
        iv.setAnimation(animationSet);

        preferences = getActivity().getSharedPreferences("config", MODE_PRIVATE);
        editor = preferences.edit();
// 记住页面
        final Boolean flag = preferences.getBoolean("flag", false);

        handler.postDelayed(new Runnable() {
            @Override
            public void run() {

                if (flag == false) {
                    editor.putBoolean("flag", true);
                    editor.commit();
                    Intent intent = new Intent(getActivity(), OtherActivity.class);
                    startActivity(intent);
                    getActivity().finish();
                }

            }
        }, 4000);

        return view;
    }
}
