android位图转换动画

Question

我正在开发一个五子棋游戏，我用canvas.drawBitmap来画棋盘和棋子。我想使用动画将这些片段从一个位置移动到另一个位置。我该怎么做呢？我想我应该做一些翻译动画。我能用位图做到这一点吗？谢谢。

Answer 1

检查此代码以设置ImageView动画：

final ImageView btnTranslate1 = (ImageView) findViewById(R.id.translate1);
Animation translateAnimation1 = new TranslateAnimation(0f, x, 0f, y);
translateAnimation1.setDuration(500);
translateAnimation1.setInterpolator(new CircInterpolator(Type.INOUT));

// start your animation with this line
btnTranslate1.startAnimation(translate1);

Answer 2

为您的棋子创建全局位置坐标并使用Animation更新它们。

Point positionOfPiece;

private static final int FINAL_X = 5;
private static final int FINAL_Y = 5;

private static final int INITIAL_X = 5;
private static final int INITIAL_Y = 5;

private class CustomAnimation extends Animation {

        @Override
        protected void applyTransformation(float interpolatedTime,
                Transformation t) {
            createLog("Updating");

            if (interpolatedTime == 0) {
                    positionOfPiece.set(INITIAL_X, INITIAL_Y);
            } else if (interpolatedTime == 1) {
                    positionOfPiece.set(FINAL_X, FINAL_Y); 
            } else {
                    positionOfPiece.set((1-interpolatedTime)*INITIAL_X + interpolatedTime*FINAL_X, (1-interpolatedTime)*INITIAL_Y + interpolatedTime*FINAL_Y);
            }
            postInvalidate();
            super.applyTransformation(interpolatedTime, t);
        }

    }

这里，插值时间将从0变化到1(*不精确地取决于内插器)。

根据你的持续时间和动画插值器。

mAnimation = new CustomAnimation();
mAnimation.setDuration(mDuration);
mAnimation.setInterpolator(mInterpolator);
startAnimation(mAnimation);
