当动画与`Animation.RELATIVE_TO_SELF`相关时，哪里是（0,0）？

Question

使用此方法时（0,0）在哪里？

public static void slideTooltip(final LinearLayout toolTipLayout) {

    TranslateAnimation layoutTranslateAnimation =
        new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0F, Animation.RELATIVE_TO_SELF, 0.0F,
            Animation.RELATIVE_TO_SELF, 2.0F, Animation.RELATIVE_TO_SELF, 0.0F);

    layoutTranslateAnimation.setDuration(10 * 1000);
    layoutTranslateAnimation.setFillAfter(true);
    // layoutTranslateAnimation.setInterpolator(new DecelerateInterpolator());

    final AlphaAnimation alphaAnimation = new AlphaAnimation(0.2F, 1.0F);
    alphaAnimation.setDuration(10 * 1000);

    toolTipLayout.startAnimation(layoutTranslateAnimation);
  }

它是窗口的左上角吗？

它是视图的左上角吗？
