나는 안드로이드 카드 게임을 만드는 eclipes를 사용하고 있습니다. 애니메이션을 호출 할 때 어떤 이유로 인해 어플리케이션이 다운됩니다. 플립 클래스에 한 가지 변경 사항이 있었고 애니메이션 메서드 "createDisplayNextView"에 오류가 있었기 때문에 layoutview를 imageview로 변경했습니다. 안드로이드 3D 플립 애니메이션
////////ANIMATION
private ImageView FrontView;
private ImageView BackView;
private boolean isFirstImage = true;
private void applyRotation(float start, float end) {
// Find the center of image
FrontView = (ImageView) findViewById(R.id.imgC1);
BackView = (ImageView) findViewById(R.drawable.clubs2);
BackView.setVisibility(View.GONE);
final float centerX = FrontView.getWidth()/2.0f;
final float centerY = FrontView.getHeight()/2.0f;
// Create a new 3D rotation with the supplied parameter
// The animation listener is used to trigger the next animation
final cardFlip rotation = new cardFlip(start, end, centerX, centerY);
rotation.setDuration(500);
rotation.setFillAfter(true);
rotation.setInterpolator(new AccelerateInterpolator());
rotation.setAnimationListener(rotation.createDisplayNextView(isFirstImage, FrontView, BackView));
if (isFirstImage) {
FrontView.startAnimation(rotation);
} else {
BackView.startAnimation(rotation);
}
}
