如何在另一個活動的ListView中顯示分析數據？

Question

我可以通過ksoap2在同一活動中顯示ListView中的名稱和位置，但我想在ListView的另一個活動中顯示名稱和位置。

我不知道該怎麼做。有人能指導我嗎？

這是我的代碼：

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

使用意向的只是傳遞contactRecords的ArrayList到另一個活動：

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

和Other_Activity得到contactRecords在活動的onCreate方法爲：

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

現在，您可以將contactRecords ArrayList用於ListView適配器作爲您的其他活動的數據源
