Question

对不起，我英语不好。很长一段时间以来，我一直在面对这个问题，但仍然无法解决。当我使用系统自己的ChangeBounds时没有问题。但是当我把Main2Acivity放在transition和SetDuration（3000）中时；删除动画后，没有任务问题。

我的代码如下：

    public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

    }

    public void onClick(View view) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            ActivityOptionsCompat activityOptionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation(this,findViewById(R.id.iv),"iv");
            startActivity(new Intent(this, Main2Activity.class),  activityOptionsCompat.toBundle());

        }
    }
}

public class Main2Activity extends AppCompatActivity {

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main2);


        MyTransition transition = new MyTransition();
        transition.addTarget("iv");
        transition.setDuration(3000);
        getWindow().setSharedElementEnterTransition(transition);

    }
}

public class MyTransition extends Transition {
    @Override
    public void captureStartValues(TransitionValues transitionValues) {
        Log.e("FMY", "captureStartValues:" + transitionValues.view.hashCode());

        transitionValues.values.put("x", transitionValues.view.getX());
        transitionValues.values.put("y", transitionValues.view.getY());

    }

    @Override
    public void captureEndValues(TransitionValues transitionValues) {
        Log.e("FMY", "captureEndValues:" + transitionValues.view.hashCode());

        transitionValues.values.put("x", transitionValues.view.getX());
        transitionValues.values.put("y", transitionValues.view.getY());

    }


    @Override
    public Animator createAnimator(ViewGroup sceneRoot, TransitionValues startValues, TransitionValues endValues) {

        Log.e("FMY", "createAnimator");
//        endValues.view.setTranslationX();
        PropertyValuesHolder propertyValuesHolderX = PropertyValuesHolder.ofFloat("x", ((Float) startValues.values.get("x")), ((Float) endValues.values.get("x")));
        PropertyValuesHolder propertyValuesHolderY = PropertyValuesHolder.ofFloat("y", ((Float) startValues.values.get("y")), ((Float) endValues.values.get("y")));
        ObjectAnimator objectAnimator = ObjectAnimator.ofPropertyValuesHolder(endValues.view, propertyValuesHolderX,propertyValuesHolderY);

        objectAnimator.setDuration(3000);
        return objectAnimator;

    }

}

Answer 1

动画以其视图移动dockerView作为父布局执行

使用过渡导致的问题
