引入

属性动画的出现，弥补了补间动画的不足之处，补间动画，只是改变了表面上的东西，但是其中属性并未改变，而属性动画相反，改变了表面上的东西，并且也更改了其属性。

代码逻辑 篇

属性动画用到的是：ObjectAnimator

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    ObjectAnimator objectAnimator1;
    ObjectAnimator objectAnimator2;
    ObjectAnimator objectAnimator3;
    private Button button;
    private ImageView image;

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

    private void initView() {
        button = (Button) findViewById(R.id.button);
        image = (ImageView) findViewById(R.id.image);
        button.setOnClickListener(this);
        image.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button:
                objectAnimator1 = ObjectAnimator.ofFloat(image,"translationX",0f,60f,0f);
                objectAnimator2 = ObjectAnimator.ofFloat(image,"translationY",0f,60f,0f);
                objectAnimator3 = ObjectAnimator.ofFloat(image,"alpha",1f,0f);
                AnimatorSet animatorSet = new AnimatorSet();
                animatorSet.play(objectAnimator1).with(objectAnimator2).before(objectAnimator3);
                animatorSet.setDuration(2000);
                animatorSet.start();
                break;
            case R.id.image:
                Toast.makeText(this, "我是属性动画", Toast.LENGTH_SHORT).show();
                break;
        }
    }
}

 AnimatorSet animatorSet = new AnimatorSet();
animatorSet.play(objectAnimator1).with(objectAnimator2).before(objectAnimator3);
animatorSet.setDuration(2000);
animatorSet.start();

再左右移动同时进行上下移动，移动完毕后，再进行透明度的变换，可以此类推往后加

参数不多做解释，不懂请看属性动画的相关文章
