java - android View 翻转动画?

标签 java android animation android-animation

我正在寻找 View 翻转器的动画。

我将如何进行动画处理,以便按下按钮时 View 基本上回到前面。其中一侧有 map View ,另一侧有 ListView 。

除了动画之外,我可以正常工作。有人可以帮我解释一下 Android 动画

在此处添加编辑

这是一些旋转动画的代码,我如何在 xml 中实现它

public class Rotate3dAnimation extends Animation {
    private final float mFromDegrees;
    private final float mToDegrees;
    private final float mCenterX;
    private final float mCenterY;
    private final float mDepthZ;
    private final boolean mReverse;
    private Camera mCamera;

/**
 * Creates a new 3D rotation on the Y axis. The rotation is defined by its
 * start angle and its end angle. Both angles are in degrees. The rotation
 * is performed around a center point on the 2D space, definied by a pair
 * of X and Y coordinates, called centerX and centerY. When the animation
 * starts, a translation on the Z axis (depth) is performed. The length
 * of the translation can be specified, as well as whether the translation
 * should be reversed in time.
 *
 * @param fromDegrees the start angle of the 3D rotation
 * @param toDegrees the end angle of the 3D rotation
 * @param centerX the X center of the 3D rotation
 * @param centerY the Y center of the 3D rotation
 * @param reverse true if the translation should be reversed, false otherwise
 */
public Rotate3dAnimation(float fromDegrees, float toDegrees,
        float centerX, float centerY, float depthZ, boolean reverse) {
    mFromDegrees = fromDegrees;
    mToDegrees = toDegrees;
    mCenterX = centerX;
    mCenterY = centerY;
    mDepthZ = depthZ;
    mReverse = reverse;
}

@Override
public void initialize(int width, int height, int parentWidth, int parentHeight) {
    super.initialize(width, height, parentWidth, parentHeight);
    mCamera = new Camera();
}

@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
    final float fromDegrees = mFromDegrees;
    float degrees = fromDegrees + ((mToDegrees - fromDegrees) * interpolatedTime);

    final float centerX = mCenterX;
    final float centerY = mCenterY;
    final Camera camera = mCamera;

    final Matrix matrix = t.getMatrix();

    camera.save();
    if (mReverse) {
        camera.translate(0.0f, 0.0f, mDepthZ * interpolatedTime);
    } else {
        camera.translate(0.0f, 0.0f, mDepthZ * (1.0f - interpolatedTime));
    }
    camera.rotateY(degrees);
    camera.getMatrix(matrix);
    camera.restore();

    matrix.preTranslate(-centerX, -centerY);
    matrix.postTranslate(centerX, centerY);
}

}

最佳答案

这取决于你想做什么,但你可以查找 Android SDK 的 wiEngine,在转换示例中...看看代码,以为文档是中文的,你可以简单地阅读代码。

另请参阅 Chet Haase 博客以获取一些提示,http://graphics-geek.blogspot.com/他有很多与动画相关的东西。定位 API 级别 12,使用 objectToAnimate.rotateYBy(360).setDuration(250f) 方法只需一行代码即可
