首先，我尝试了所有 java.lang.Stackoverflowerror 错误问题，但没有改变这个错误。为什么我收到此错误？

我的 ListeleActivity 课程是；

 package com.mobil.eposta;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import javax.mail.Message;
import android.app.Activity;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import android.widget.Toast;

public class ListeleActivity extends Activity
{
    static List<String> gelen;
    static ListView listView;
    static ArrayList<String> konulist;
    static ArrayList<String> kimdenlist;
    static ArrayList<String> govdelist;

    static ArrayList<String> dosyaIsmi;
    static Message[] messageslist;
    static int messagePosition;
    static int onClickPosition;
    static boolean messageEkBulunuyormu;

    ArrayList<String> eklist;
    int clickKonum;
    static boolean ekvar;

    ListView lv;
    Button btnSave, btnClear;
    HashMap<Integer, Boolean> mCartItems = new HashMap<Integer, Boolean>();

    Baglanti baglantiNesnesi = new Baglanti();
//  EkDurumu ekdurumuNesnesi = new EkDurumu();
//  GoruntuleActivity goruntuleNesnesi = new GoruntuleActivity();

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listalt);

        konulist = (ArrayList<String>) baglantiNesnesi.getKonu();
        kimdenlist = (ArrayList<String>) baglantiNesnesi.getKimden();
        govdelist = (ArrayList<String>) baglantiNesnesi.getGovde();
        messageslist = baglantiNesnesi.messages;

        lv = (ListView) findViewById(R.id.list);
        LayoutInflater mLInflater = getLayoutInflater();
        final ListViewAdapter adapter = new ListViewAdapter(getApplicationContext(),
                kimdenlist, konulist, mLInflater);
        lv.setAdapter(adapter);
        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
              @Override
              public void onItemClick( AdapterView<?> parent, View item, 
                                       int position, long id) 
              {
                    final Intent intent = new Intent(ListeleActivity.this, GoruntuleActivity.class);
                    startActivity(intent);
                    onClickPosition = position;
                    Toast.makeText(ListeleActivity.this, "Bastın", Toast.LENGTH_SHORT).show();
              }
            });
    }
}

我的 GoruntuleActivity.class 是；

public class GoruntuleActivity extends Activity
{
    ListeleActivity listeleNesnesi = new ListeleActivity();

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.epostagoruntuleme);
         }
}

不要自己创建活动。这些行是不必要的（并导致您的堆栈溢出）：

ListeleActivity listeleNesnesi = new ListeleActivity();

GoruntuleActivity goruntuleNesnesi = new GoruntuleActivity();

您无需调用活动的构造函数，而是通过创建一个 newIntent并将其传递给startActivity. 阅读这篇关于Android Fundamentals的文档以获得更多解释。
