当我运行我的应用程序时，所有复选框都在我的ListView中选中，但我不希望它们在开始时被选中。我想我没有写onDestroy()正确。
请帮帮我！

onDestroy 不能保证被调用。大多数情况下，如果操作系统想要关闭应用程序，则可以调用它。
您可以使用 onBackPress 或 onPause 代替
我不确定您处理共享首选项的方式。这就是我通常的做法。将 onDestroy 代码更改为;
public void onDestroy(){
super.onDestroy();
SharedPreferences myPrefs = this.getSharedPreferences("states", Context.MODE_PRIVATE);
SharedPreferences.Editor myEditor=myPrefs.edit();
myEditor.clear();
myEditor.commit();
}
