我可以ListView通过 ksoap2 在同一活动中显示名称和位置，但我想在 a 中显示另一个活动中的名称和位置ListView。

我不知道该怎么做。有人可以指导我吗？

这是我的代码：

package com.example.rotaryclubnew;

只需使用 Intent 将 contactRecords ArrayList 传递给另一个活动：

Intent intent = new Intent(Searchcontactswithposition.this, Other_Activity.class);
intent.putStringArrayListExtra("contactRecords_list", contactRecords);
startActivity(intent);

并在 Other_Activity 中获取contactRecords，就像在 Activity 的 onCreate 方法中一样：

contactRecords = getIntent().getStringArrayListExtra("contactRecords_list");

现在，您可以使用 listView Adapter 的 contactRecords ArrayList 作为其他活动的数据源
