Question

我需要创建CardViews到RelativeLayout。在CardView内部，还有其他视图，例如ImageView和TextView。它们被添加了，但是似乎它们不遵守我要添加到LayoutParams中的规则。这是我的代码：

CardView infoCardView=new CardView(HotelActivity.this);
        infoCardView.setId(2);
        RelativeLayout.LayoutParams cardViewParams=new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        RelativeLayout.LayoutParams iconLp=new RelativeLayout.LayoutParams(20,20);
        RelativeLayout.LayoutParams textLP=new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        //imagen is another ImageView that is being drawn ok in the RelativeLayout. Also, the cardView is drawn below the ImageView, which is ok.
        cardViewParams.addRule(RelativeLayout.BELOW,imagen.getId());
        infoCardView.setLayoutParams(cardViewParams);
        iconLp.addRule(RelativeLayout.CENTER_VERTICAL, RelativeLayout.TRUE);
        iconLp.addRule(RelativeLayout.ALIGN_PARENT_START, RelativeLayout.TRUE);
        iconLp.setMarginStart(20);
        //Icono del cardView
        ImageView icono=new ImageView(HotelActivity.this);
        icono.setId(3);
        //icono.setLayoutParams(iconLp);
        icono.setBackground(getDrawable(android.R.drawable.ic_dialog_info));
        infoCardView.addView(icono,iconLp);
        //TextView título del CardView
        TextView tvInfo=new TextView(HotelActivity.this);
        tvInfo.setId(4);
        tvInfo.setTextSize(17);
        tvInfo.setText(getString(R.string.info));
        tvInfo.setTypeface(tvInfo.getTypeface(), Typeface.BOLD);
        textLP.addRule(RelativeLayout.END_OF,icono.getId());
        textLP.setMarginStart(20);
        tvInfo.setTextColor(getColor(R.color.white));
        //tvInfo is NOT added to the END of icono, instead is overlapping it.
        infoCardView.addView(tvInfo, textLP);
         infoCardView.setRadius(9);
        infoCardView.setBackgroundColor(Color.parseColor(almacen.getEvento().getBgColor()));
        infoCardView.setElevation(9);
        rl.addView(infoCardView,cardViewParams);

我做错了什么？

谢谢。

已解决。问题是，我正在为CardView设置一些不适用于它的规则，例如CENTER_VERTICAL。因此，我添加了另一个RelativeLayout作为CardView的儿子，将视图添加到该RelativeLayout，将该RelativeLayout添加到CardView，现在视图已正确绘制。

以编程方式将视图添加到RelativeLayout内部的CardView中
