Unity与安卓交互（四）控制UnityView布局

1、获取Layout布局

LinearLayout mParent=(LinearLayout)findViewById(R.id.UnityView);

2、获取Unity视图

View mView=mUnityPlayer.getView();

3、将Unity视图添加到Android视图中

mParent.addView(mView);

4、获取LayoutParams

        LinearLayout会报错，根据报错内容，定义了ConstraintLayout。

ConstraintLayout.LayoutParams layoutParams =  (ConstraintLayout.LayoutParams)mParent.getLayoutParams();

5、创建一个ValueAnimator

ValueAnimator valueAnimator = ValueAnimator.ofInt(10,300);

6、添加监听

valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
    @Override
    public void onAnimationUpdate(ValueAnimator valueAnimator) {
        layoutParams.setMarginEnd((int)valueAnimator.getAnimatedValue());
        mParent.setLayoutParams(layoutParams);
    }
});

7、设置时间，并启动动画

valueAnimator.setDuration(3000);
valueAnimator.start();
