下面给大家分享一个有趣的动画：这里比较适合一张图片的翻转，如果是多张图片，可以参考APIDemo里的例子，就是加个ArrayAdapter，还是简单的，也可以自己发挥修改，实现自己想要的。这里的代码基本上可以直接运行项目了。
在main.xml里加个ImageView，如
复制代码 代码如下:
android:layout_width="fill_parent"
android:layout_height="fill_parent">
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Rotate"
android:textSize="50px"
android:layout_x="150px"
android:layout_y="30px"
android:src="@drawable/ro">
>
这个不需要解释吧，都可以看懂的
最后，还需要一个activity类
如：
复制代码 代码如下:
public class TestRotate extends Activity implements OnClickListener{
private mageView imageview;
private ViewGroup mContainer;
private static final int IMAGE = R.drawable.ro;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
imageview = (ImageView) findViewById(R.id.image);
mContainer = (ViewGroup) findViewById(R.id.container);
imageview.setImageResource(IMAGE);
imageview.setClickable(true);
imageview.setFocusable(true);
imageview.setonClickListener(this);
}
private void applyRotation(int position, float start, float end) {
// Find the center of the container
final float centerX = mContainer.getWidth() / 2.0f;
final float centerY = mContainer.getHeight() / 2.0f;
final Rotate3d rotation =
new Rotate3d(start, end, centerX, centerY, 310.0f, true);
rotation.setDuration(500);
rotation.setFillAfter(true);
rotation.setInterpolator(new AccelerateInterpolator());
rotation.setAnimationListener(new DisplayNextView(position));
mContainer.startAnimation(rotation);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
applyRotation(0,0,90);
}
private final class DisplayNextView implements Animation.AnimationListener {
private final int mPosition;
private DisplayNextView(int position) {
mPosition = position;
}
public void onAnimationStart(Animation animation) {
}
public void onAnimationEnd(Animation animation) {
mContainer.post(new SwapViews(mPosition));
}
public void onAnimationRepeat(Animation animation) {
}
}
private final class SwapViews implements Runnable {
private final int mPosition;
public SwapViews(int position) {
mPosition = position;
}
public void run() {
final float centerX = mContainer.getWidth() / 2.0f;
final float centerY = mContainer.getHeight() / 2.0f;
Rotate3d rotation;
if (mPosition > -1) {
imageview.setVisibility(View.VISIBLE);
imageview.requestFocus();
rotation = new Rotate3d(90, 180, centerX, centerY, 310.0f, false);
} else {
imageview.setVisibility(View.GONE);
rotation = new Rotate3d(90, 0, centerX, centerY, 310.0f, false);
}
rotation.setDuration(500);
rotation.setFillAfter(true);
rotation.setInterpolator(new DecelerateInterpolator());
mContainer.startAnimation(rotation);
}
}
}
