自定义ViewGroup，但是效果不是想要的？

我用HorizontalScrollView装载个数不定的自定义ViewGroup,因为从服务器拉取数据，再呈现，但是尺寸有问题，而且两个子控件只显示了一个。我贴一下我的代码 麻烦大神帮帮忙了。
想要的效果是 这个的

上面一个ImageView,下面一个TextView

自定义的ViewGroup

public class FFTagImgView extends ViewGroup {

        private Context context;
        //图片
        private ImageView imageView;
        //标签
        private TextView tagLabel;
        //标志FFTAGIMGVIEW
        private int tagImg;
    
        public FFTagImgView(Context context) {
            super(context);
            this.context = context;
    
            initView();
        }
    
        public static FFTagImgView newInstance(Context context,int tag){
            FFTagImgView imgView = new FFTagImgView(context);
            imgView.tagImg = tag;
            return imgView;
        }
    
        public FFTagImgView(Context context, AttributeSet attrs) {
            super(context, attrs);
            this.context = context;
        }
    
        private void initView(){
            this.setBackgroundColor(context.getResources().getColor(R.color.white));
    
            this.imageView = new ImageView(context);
            LinearLayout.LayoutParams lp1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 60);
            imageView.setLayoutParams(lp1);
            addView(imageView);
    
            this.tagLabel = new TextView(context);
            LinearLayout.LayoutParams lp2 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,20);
            tagLabel.setLayoutParams(lp2);
            addView(tagLabel);
        }
    
        @Override
        //布局子控件,left top right bottom 当前ViewGroup相对于其父控件的坐标位置
        //changed 该参数指出当前ViewGroup的尺寸或者位置是否发生了改变
        protected void onLayout(boolean changed, int l, int t, int r, int b) {
    
            //当前ViewGroup的总宽度
            int mViewGroupWidth = getMeasuredWidth();
            int mPainterPosX = l;  //当前绘图光标横坐标位置
            int mPainterPosY = t;  //当前绘图光标纵坐标位置
    
            int childCount = getChildCount();
            System.out.println("子控件的个数："+childCount);
            for (int i = 0;i<childCount;i++){
                View childView = getChildAt(i);
    
                //得到子控件的宽高
                int width = childView.getMeasuredWidth();
                int height = childView.getMeasuredHeight();
    
                if (i == 0){
                    childView.layout(0,0,mViewGroupWidth,60);
                }else if(i == 1){
                    childView.layout(0,60,mViewGroupWidth,20);
                }
            }
        }
    
        @Override
        protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    
            setMeasuredDimension(70,80);
        }
    
        public ImageView getImageView() {
            return imageView;
        }
    
        public void setImageView(ImageView imageView) {
            this.imageView = imageView;
        }
    
        public TextView getTagLabel() {
            return tagLabel;
        }
    
        public void setTagLabel(TextView tagLabel) {
            this.tagLabel = tagLabel;
        }
    
        public int getTagImg() {
            return tagImg;
        }
    
        public void setTagImg(int tagImg) {
            this.tagImg = tagImg;
        }
    }
    

这段代码是在Activity中的使用代码：

我的效果这样。。。正常的应该填满我截图的区域

跟XML布局有关系？

首先setMeasuredDimension(70,80);你这里都定死了宽高了，而且你第二个子view的的bottom坐标写错了，跟第一个imageview重合了应该改为childView.layout(0,60,mViewGroupWidth,80);

---

if (i == 0) {
    childView.layout(0,0,mViewGroupWidth,60);
} else if(i == 1) {
    childView.layout(0,60,mViewGroupWidth,20);
}

改成

if (i == 0) {
    childView.layout(0, 0, mViewGroupWidth, 60);
} else if(i == 1) {
    childView.layout(0, 60, mViewGroupWidth, 80);
}

试试吧，不过我不太确定。。。
