android - 根据地图大小在特定位置的现有 LinearLayout 中添加视图

看起来像这样 -
我想要实现的是在“可用性”文本视图下方我想添加文本视图，以与可用性相同的方式显示信息。
到目前为止我尝试过的 -
for (String key : selectedProductAttributesMap.keySet()) {
TextView textView = new TextView(this);
textView.setText(key);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.setMargins(14,15,14,0);
textView.setLayoutParams(params);
nestedLinearLayout.addView(textView);
}
它在线性布局的底部创建视图，所以我错过了将其放在特定位置的选项。我怎样才能做到这一点？
解决方案
添加一个LinearLayout您有评论的地方<!-- This is where I want to add the dynamic views -->并在其中添加 TextViews ViewGroup，而不是nestedLinearLayout
至于
所以我错过了将它放在特定位置的选项
您可以addView使用第二个int参数调用，该参数是您希望插入视图的索引
