ImageView.getLeft（）仍会在属性动画

Question

我有9个ImageView，其中8个是可点击的，而imageView9是不可点击的，当点击每个可点击的imageView时，它将使用属性动画将其位置与imageView9交换。 根据我的理解，如果我在ImageView上使用属性动画，它还应该更新ImageView的实际位置。但是，在这种情况下，即使imageView 9已经移动到单击的imageView的位置，每个imageView也会移动到原始位置（如果是imageView9）。我在这里想念的是什么？

MainActivity.java

public class MainActivity extends Activity implements View.OnClickListener {

    ImageView imageView1, imageView2, imageView3, imageView4, imageView5, imageView6, imageView7, imageView8, imageView9;
    int x, y, lMargin, tlMargin;

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

        imageView1 = (ImageView) findViewById(R.id.image1);
        imageView2 = (ImageView) findViewById(R.id.image2);
        imageView3 = (ImageView) findViewById(R.id.image3);
        imageView4 = (ImageView) findViewById(R.id.image4);
        imageView5 = (ImageView) findViewById(R.id.image5);
        imageView6 = (ImageView) findViewById(R.id.image6);
        imageView7 = (ImageView) findViewById(R.id.image7);
        imageView8 = (ImageView) findViewById(R.id.image8);

        // imageView9 is not clickable, when other imageView is clicked,
        // The clicked imageView swaps its position with imageView9
        imageView9 = (ImageView) findViewById(R.id.image9);

        imageView1.setOnClickListener(this);
        imageView2.setOnClickListener(this);
        imageView3.setOnClickListener(this);
        imageView4.setOnClickListener(this);
        imageView5.setOnClickListener(this);
        imageView6.setOnClickListener(this);
        imageView7.setOnClickListener(this);
        imageView8.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {

        // Get position of imageView9
        lMargin = imageView9.getLeft();

        // Get position of currently clicked imageView
        tlMargin = v.getLeft();

        ObjectAnimator blockAnim = ObjectAnimator.ofFloat(v, "x", lMargin);
        blockAnim.setDuration(1000);
        blockAnim.setRepeatCount(0);
        blockAnim.start();

        ObjectAnimator emptyAnim = ObjectAnimator.ofFloat(findViewById(R.id.image9), "x", tlMargin);
        emptyAnim.setDuration(1000);
        emptyAnim.setRepeatCount(0);
        emptyAnim.start();

    }
}
