如何在Android Studio中的imageView上添加具有不同轴的两个旋转？

Question

I was trying to do rotations on an ImageView , each of which has its own pivot . One is meant to have default pivots while the other has (0, 0) as its pivots. While trying to do this, only the last rotation is done on the view. How can I have them both work simultaneously?

Here is my attempt:

  this.animate().rotation(180f).setDuration(0);
  setPivotX(0);
  setPivotY(0);
  this.animate().rotation((float) Math.toDegrees(Math.atan((y2 - y1) / (x2 - x1)))).setDuration(0);

This is done inside a function of a class implementing imageView .

You should use ParallelTransition, here is my example for it:

ParallelTransition pt = new ParallelTransition();

    RotateTransition rx=new RotateTransition(Duration.seconds(5), this);
    rx.setAxis(Rotate.X_AXIS);

    RotateTransition rz=new RotateTransition(Duration.seconds(5), this);
    rz.setAxis(Rotate.Z_AXIS);

    rx.setFromAngle(0);
    rx.setToAngle(90*xrotate);

    rz.setFromAngle(0);
    rz.setToAngle(90*zrotate);

    pt.getChildren().addAll(rz,rx);

    pt.play();
