public class MainActivity extends AppCompatActivity {

    private static final String TAG = "结果是";

    private ImageView iv_image;

    @Override

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        iv_image = findViewById(R.id.iv_image);

    }

    public void set(View view) {

        AnimatorSet as = new AnimatorSet();

        ObjectAnimator oa = ObjectAnimator.ofFloat(iv_image, "translationX", 10, 50, 20, 100);

        ObjectAnimator oa2 = ObjectAnimator.ofFloat(iv_image, "scaleY", 0.1f, 2, 1, 2);

        ObjectAnimator oa3 = ObjectAnimator.ofFloat(iv_image, "alpha", 0, 0.5f, 0, 1);

        ObjectAnimator oa4 = ObjectAnimator.ofFloat(iv_image, "rotationY", 0, 180, 90, 360);

        as.setDuration(2000);

        as.setTarget(iv_image);

        as.playTogether(oa, oa2, oa3, oa4);

        as.start();

    }

    public void translate(View view) {

        ObjectAnimator oa = ObjectAnimator.ofFloat(iv_image, "translationX", 10, 50,20,100,150);

        oa.setDuration(2000);

        oa.start(); //开始动画

    }

    public void scale(View view) {

        ObjectAnimator oa = ObjectAnimator.ofFloat(iv_image, "scaleY", 0.1f, 2, 1, 2);

oa.setDuration(2000);

oa.start();

    }

    public void rotate(View view) {

        ObjectAnimator oa = ObjectAnimator.ofFloat(iv_image, "rotation", 0, 180, 90, 360);

        oa.setDuration(2000);

        oa.start();

    }

    public void alpha(View view) {

        ObjectAnimator oa = ObjectAnimator.ofFloat(iv_image, "alpha", 0, 0.5f, 0, 1,0,1);

        oa.setDuration(2000);

        oa.start();

    }
