Android ImageView: how can I get the current rotation angle?
2 answers
Preserve rotation angle:
ImageView arrow = (ImageView) findViewById(R.id.arrow);
float x = arrow.getPivotX();
float y = arrow.getPivotY();
RotateAnimation anim = new RotateAnimation(arrowRotateStartAngle, arrowRotateXAngle, arrow.getWidth()/2, arrow.getHeight()/2);
anim.setFillAfter(true);
anim.setDuration(1000);
arrow.startAnimation(anim);
temRotate = arrowRotateStartAngle;
arrowRotateStartAngle = arrowRotateXAngle;
arrowRotateXAngle = temRotate;
