android - 如何在另一个 Activity 的 ListView 中显示解析后的数据？

Question

我可以通过 ksoap2 在同一 Activity 的 ListView 中显示名称和位置，但我想在 ListView 的另一个 Activity 中显示名称和位置.

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;
import java.util.ArrayList;
import java.util.List;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

Answer 1

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

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 contactRecords ArrayList for ListView Adapter 作为其他 Activity 的数据源
