Android在百度地图上通过InfoWindow添加旋转式菜单的问题。 10C

在网上找了一个旋转式菜单的源码,运行效果如下图片说明图片说明运行效果正常,其onMeasure,onLayout,以及控制旋转的方法如下
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
mMaxChildWidth = 0;
mMaxChildHeight = 0;

    // Measure once to find the maximum child size.
    int childWidthMeasureSpec = MeasureSpec.makeMeasureSpec(
            MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.AT_MOST);
    int childHeightMeasureSpec = MeasureSpec.makeMeasureSpec(
            MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.AT_MOST);

    final int count = getChildCount();
    for (int i = 0; i < count; i++) {
        final View child = getChildAt(i);
        if (child.getVisibility() == GONE) {
            continue;
        }

        child.measure(childWidthMeasureSpec, childHeightMeasureSpec);

        mMaxChildWidth = Math.max(mMaxChildWidth, child.getMeasuredWidth());
        mMaxChildHeight = Math.max(mMaxChildHeight,
                child.getMeasuredHeight());
        System.out.println(mMaxChildWidth + "----------" + mMaxChildHeight
                + "----------" + count + "");

    }

    // Measure again for each child to be exactly the same size.
    childWidthMeasureSpec = MeasureSpec.makeMeasureSpec(mMaxChildWidth,
            MeasureSpec.EXACTLY);
    childHeightMeasureSpec = MeasureSpec.makeMeasureSpec(mMaxChildHeight,
            MeasureSpec.EXACTLY);

    for (int i = 0; i < count; i++) {
        final View child = getChildAt(i);
        if (child.getVisibility() == GONE) {
            continue;
        }

        child.measure(childWidthMeasureSpec, childHeightMeasureSpec);
    }

    setMeasuredDimension(resolveSize(mMaxChildWidth, widthMeasureSpec),
            resolveSize(mMaxChildHeight, heightMeasureSpec));

}

@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
    int layoutWidth = r - l;
    int layoutHeight = b - t;

    // Laying out the child views

            : layoutHeight / 3;

    childWidth = (int) (radius / 1.5);
    childHeight = (int) (radius / 1.5);

    float angleDelay = 360 / getChildCount();

    for (int i = 0; i < childCount; i++) {
        final CircleImageView child = (CircleImageView) CircleLayout.this
                .getChildAt(i);
        if (child.getVisibility() == GONE) {
            continue;
        }

        if (angle > 360) {
            angle -= 360;
        } else {
            if (angle < 0) {
                angle += 360;
            }
        }

        child.setAngle(angle);
        child.setPosition(i);

        left = Math
                .round((float) (((layoutWidth / 2) - childWidth / 2) + radius

                        * Math.sin(Math.toRadians(angle))));

        child.layout(left, top, left + childWidth, top + childHeight);

        System.out.println(child.toString() + "onlayout");

        angle += angleDelay;
    }

}

/**

                        * Math.sin(Math.toRadians(angle))));

        child.setAngle(angle);

        if (Math.abs(angle - firstChildPos) < (angleDelay / 2)
                && selected != child.getPosition()) {
            selected = child.getPosition();

            if (mOnItemSelectedListener != null && rotateToCenter) {
                mOnItemSelectedListener.onItemSelected(child, selected,

我要把这个旋转菜单通过点击地图上的Marker打开,使用百度地图的InfoWindow类添加,java文件都没有改,自己写了一个xml文件circle_rotate_layout.xml,也与demo里的类似,点击Marker添加菜单的代码如下:
mBaiduMap.setOnMarkerClickListener(new OnMarkerClickListener() {

        @Override
        public boolean onMarkerClick(Marker marker) {
            ViewGroup view = new RelativeLayout(
                    getApplicationContext());
            LayoutInflater lf1 = getLayoutInflater();
            view =  (ViewGroup) lf1.inflate(
                    R.layout.circle_rotate_layout, null);

            CircleLayout cl = (CircleLayout) view
                    .findViewById(R.id.circle_layout);

            cl.setOnItemSelectedListener(MainActivity.this);
            cl.setOnItemClickListener(MainActivity.this);
            // OnInfoWindowClickListener listener = null;
            for (int i = 0; i < markerlist.size(); i++) {

                if (marker == markerlist.get(i)) {

                    LatLng ll = marker.getPosition();
                    mInfoWindow = new InfoWindow(view, ll, 0);
                    mBaiduMap.showInfoWindow(mInfoWindow);
                }
            }
            return false;
        }
    });
    但是这样的效果却是![图片说明](https://img-ask.csdn.net/upload/201611/11/1478853712_785359.png)![图片说明](https://img-ask.csdn.net/upload/201611/11/1478853737_732981.png)
    菜单一直很小,怎么都弄不大,而且onLayout方法确定位置绘制粗始菜单项之后,后面rotateButtons旋转菜单时,刚开始绘制的菜单项会一直存在,旋转的相当于是另一组菜单项,请问大神们该怎么解决这两个问题
