                </LinearLayout>

            </LinearLayout>
        </android.support.v4.widget.NestedScrollView>

    </android.support.constraint.ConstraintLayout>

看起来像这样 -

我想要实现的是在 "availability" textview 下面我想添加 textview 以与可用性相同的方式显示信息。

到目前为止我尝试了什么 -

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，因此我缺少将它放在特定位置的选项。我怎样才能做到这一点？

在您有评论的地方添加 LinearLayout  并在 ViewGroup 中添加 TextView，而不是 nestedLinearLayout

至于

so I am missing the option to put it at a specific place

您可以使用第二个 int 参数调用 addView，该参数是您要插入视图的索引

根据地图大小在特定位置的现有 LinearLayout 内添加视图
