我是Android开发的新手。
我正在开发一款名为2048的游戏。
是否有可能完成细胞运动动画？如果是，怎么样？
我的代码：
public class GameView extends ImageView {
private Paint paint;
private Paint textPaint;
private int width;
private int height;
public GameView(Context context) {
super(context);
initialize();
}
public GameView(Context context, AttributeSet attrs) {
super(context, attrs);
initialize();
}
public GameView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initialize();
}
private void initialize() {
paint = new Paint();
paint.setColor(Color.parseColor("#aaaaaa"));
paint.setStyle(Style.FILL_AND_STROKE);
paint.setAntiAlias(true);
textPaint = new Paint();
textPaint.setColor(Color.parseColor("#000000"));
textPaint.setStyle(Style.FILL);
textPaint.setAntiAlias(true);
textPaint.setTextSize(G.convertDpToPixel(48));
textPaint.setTextAlign(Align.CENTER);
}
@Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
super.onLayout(changed, left, top, right, bottom);

width = getWidth();
} else {
width = getHeight();
}
}

dropNextNumber();

}
}
}

和this我的截图。
我尝试了很多方法，但没有任何解决方案。
我很感激耐心，并逐步解释。
我想设置this之类的动画。
谢谢你的朋友们。
