I'm trying to convert the example done in b4a to b4j, but it is not showing animation of the flip cards!



Can anyone help me? below are the sources.

B4A source ( main source by @LucasMS ) ( Topic Here )
B4J source ( DOWNLOAD ) ( I applied both algorithms, but none of them worked... )

B4j doesn't support flip card animations ?

No. the rotate(x,y,z) method is only for b4a and b4i in SD_XuiView library

See here

It refers to a specific library not in general how to do this

only java B4A sample:

B4X:
private Sub FlipImageJava (RotationX As Float, RotationY As Float, Rotation As Float)
    jo.RunMethod("flipImage", Array As Object(mBaxView, RotationX, RotationY, Rotation, 1280.0f * Density))
End Sub

Java:
#IF JAVA
public void flipImage (ImageView imageView, float RotationX, float RotationY, float Rotation, float CameraDistance)
{
    import android.widget.ImageView;
    import android.util.DisplayMetrics;
  
    //BA.LogInfo("flipImage: In");

    /*---------------------------------------------------------------------------------------
    //Better to use parameter CameraDistance as B4A already provides the information required.
    //However, here's a way to do it:
    DisplayMetrics metrics = getResources().getDisplayMetrics();
    float CameraDistance = 1280.0f * (metrics.density * 160f);
    ----------------------------------------------------------------------------------------
    */
    float PivotX = imageView.getWidth()/2.0f;                    //'width centre
    float PivotY = imageView.getHeight()/2.0f;                    //height centre

    imageView.setPivotX(PivotX);
    imageView.setPivotX(PivotX);
    imageView.setPivotY(PivotY);
    imageView.setRotationX(RotationX);
    imageView.setRotationY(RotationY);
    imageView.setRotation(Rotation);
    imageView.setCameraDistance(CameraDistance);
  
    //BA.LogInfo("flipImage: Out");
}
#End If

simple demo JavaFX - Transformations

It wants to rotate on the Z axis, and there is no general method for views or nodes
