【问题描述】：
所以我有这个小应用程序，您可以从中调用。 在此应用程序中，您将能够使用您的电话号码登录并从我们的服务器获取一个号码（这尚未实现）
根据“你是谁”，我们的服务器会动态地给你一个号码。
这并不真正相关，但它仍然与我的问题有关。
由于我们的服务器提供了号码，因此我无法使用从 Android CallLogs 获得的信息创建“最近列表”。 （它可能会将数字 A.E “妈妈” 加入您的专业联系人列表等）
所以我现在要做的是，在每次通话后，将信息（姓名、号码、日期和持续时间）插入到数组列表中。
recentCalls.add(new Recent(aName, aDate, aNumber, "0"));
（0 代表秒，持续时间。仍未完成。）
它会暂时在应用程序中“保存”，当应用程序完全终止（或崩溃）时，所有内容都会被清空。
我考虑过将数组列表保存在 SharedPreferences 中。
但由于我们要将最近的次数限制为 100，这将太大了。
我已阅读：Android Storage Options 无论哪种方式，我仍然会从手机本身获取所有通话记录，以进行测试。
我的问题是：
- 如何安全有效地保存 ArrayList
- 如果我不打算使用 ArrayList，我如何“格式化”ACTUAL 电话的 call_logs 以仅显示从我的应用程序拨打的号码。 （为了“通过”我们的服务器调用，我们使用“ServerPhoneNumber”+“,”+“Inserted PhoneNumber” - 示例：123456789,987654321）
- 我可以说检查前 10 个字符是否等于“123456789”吗？这是不可能的，因为它会根据人改变数字。
这是我的 Java 代码：

});
}
这是我目前的调用方法。 （注释掉的东西，因为它不再像旧代码了。）
基本上每当我点击通话时，
case R.id.bCall:
call();
调用函数：
private void call() {
// TODO Auto-generated method stub
if(numberfield.length() > 0){
try {
Intent callIntent = new Intent(Intent.ACTION_CALL);
String dsPhoneNumber = "+34965063314,";
// Dynamic number
//965063064
String string = numberfield.getText().toString().trim();
number = "tel:" + dsPhoneNumber + string;
callIntent.setData(Uri.parse(number));
startActivity(callIntent);
//recentCalls.add(new Recent(aName, aDate, aNumber, "0"));
} catch (ActivityNotFoundException activityException) {
Log.e("helloandroid dialing example", "Call failed");
}
}else {
Context context = getApplicationContext();
CharSequence text = getResources().getText(R.string.keypadViewToastEmptyNumber);
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
}
它需要将其插入“列表”并显示在“最近”选项卡上。 我花了几个小时试图解决这个问题，没有进展。提前致谢！

}
所以这是最近标签的视图。 .getDate/.getDuration 等已更改，“新的”应该是什么？所以基本上阅读

如果您真的想将数据写入文件，为什么不将我们的数据存储为 json 格式。它也非常容易解析，您可以使用 Gson。我会使用 sqllite 数据库，这对我来说似乎最合乎逻辑，然后您可以查询最近的 100 个数字。
