老师的动画上下左右判断错了？Toast的结果和实际的不一致

public void changeDataByImageView(final ImageView mImageView) {

// 创建动画，设置方向、移动距离

TranslateAnimation translateAnimation = null;

if (mImageView.getX() > iv_null_ImageView.getX()) {// 在空方块下面

// 往上移动

translateAnimation = new TranslateAnimation(0.1f, -mImageView.getWidth(), 0.1f, 0.1f);

Toast.makeText(MainActivity.this, "上移", Toast.LENGTH_SHORT).show();

} else if (mImageView.getX() < iv_null_ImageView.getX()) {//

// 下

translateAnimation = new TranslateAnimation(0.1f, mImageView.getWidth(), 0.1f, 0.1f);

Toast.makeText(MainActivity.this, "下移", Toast.LENGTH_SHORT).show();

} else if (mImageView.getY() > iv_null_ImageView.getY()) {//

// 左

translateAnimation = new TranslateAnimation(0.1f, 0.1f, 0.1f, -mImageView.getWidth());

Toast.makeText(MainActivity.this, "左移", Toast.LENGTH_SHORT).show();

} else if (mImageView.getY() < iv_null_ImageView.getY()) {//

// 右

translateAnimation = new TranslateAnimation(0.1f, 0.1f, 0.1f, mImageView.getWidth());

Toast.makeText(MainActivity.this, "右移", Toast.LENGTH_SHORT).show();

}

// 设置动画时长

translateAnimation.setDuration(70);

// 动画结束之后停留

translateAnimation.setFillAfter(true);

// 动画结束后真正的把数据交换
