java - 尝试从另一个 Activity 调用 Activity 时出现 StackOverflowError

Question

我正在尝试开发一个小型应用程序 BusTracker，当您提到往返地点时，它会列出巴士列表。 我有一个 frombutton，单击该按钮将调用另一个 Activity (这是一个列表 Activity )，该 Activity 将显示位置列表。我选择一个，该位置将被保存，并且第一个 Activity 中的文本字段将被填充。我在第二个 Activity 的 oncreate 方法中收到 stackOverFlowerror 。谁能给我一个可能的原因吗？

这是我在firstActivity onClick方法中的代码

case R.id.from_button:
Intent i= new Intent(this,PlacesActivity.class);
startActivity(i);
String ss=PlacesActivity.getPlace();

然后在第二个Activity中

this.onCreate(onSavedInstanceState);
    setContentView(R.layout.places);
     ListView placesList=(ListView)this.findViewById(R.layout.places);

     placesList.setVisibility(View.VISIBLE);
     placesList.setAdapter(new ArrayAdapter(this,R.array.fromArray));
     placesList.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
     //placesList.setOnItemClickListener(this);

}

public void onListItemClick(ListView l, View v, int position, long id)
{
    Object o=this.getListAdapter().getItem(position);
    String s=o.toString();
    place=s;
    System.out.println("sssssssssssss"+s);
}

我得到的错误:

Answer 1

你不应该调用this.onCreate(onSavedInstanceState);，而应该调用super.onCreate(onSavedInstanceState);，否则你会陷入无限递归调用create和然后你会得到 STackOverflow。
