本文介绍了一个Android应用中的欢迎界面动画实现方法，通过AnimatorSet组合了位移、透明度、旋转和平移等动画效果，并在动画结束后实现了页面跳转。

public class WelcomActivity extends AppCompatActivity {

    private ImageView imageView;
   /* Handler handler=new Handler(){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            Intent intent=new Intent(WelcomActivity.this,XiangQingActivity.class);
            startActivity(intent);
            finish();
        }
    };*/


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcom);

        imageView = findViewById(R.id.image_view);

        ObjectAnimator y = ObjectAnimator.ofFloat(imageView, "Y", 0, 500, 800, 1000);

        ObjectAnimator alpha = ObjectAnimator.ofFloat(imageView, "alpha", 0.5f, 1);

        ObjectAnimator rotationX = ObjectAnimator.ofFloat(imageView, "rotation", 0,90,180,270, 360);
        ObjectAnimator rotationY = ObjectAnimator.ofFloat(imageView, "rotation", 0,90,180,270, 360);

        ObjectAnimator scaleX = ObjectAnimator.ofFloat(imageView, "scaleX", 0.5f, 2);
        ObjectAnimator scaleY = ObjectAnimator.ofFloat(imageView, "scaleY", 0.5f, 2);

        //组合
        AnimatorSet animatorSet = new AnimatorSet();

        //放到一起
     //   animatorSet.play(y).with(alpha).with(scaleX).with(scaleY).with(rotationX);
        animatorSet.play(y).with(alpha).with(rotationX).with(rotationY).with(scaleX).with(scaleY);

        animatorSet.setDuration(3000);
        animatorSet.start();

        animatorSet.addListener(new Animator.AnimatorListener() {
            @Override
            public void onAnimationStart(Animator animator) {

            }

            @Override
            public void onAnimationEnd(Animator animator) {
                //动画结束跳转页面
                Intent intent=new Intent(WelcomActivity.this,XiangQingActivity.class);
                startActivity(intent);
                finish();

            }

            @Override
            public void onAnimationCancel(Animator animator) {

            }

            @Override
            public void onAnimationRepeat(Animator animator) {

            }
        });

    }
}
