所以我有这个小应用程序你可以打电话给。 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（这是未实施的）
根据“你是谁”，我们的服务器会动态给你一个号码。
这不是真正相关的，但它仍然与我的问题有关。
由于我们的服务器提供了号码，我无法使用Android CallLogs获得的信息制作“最近列表”。 （它可能会将A.E“妈妈”写入您的专业联系人名单等等）
所以我现在正在做的是，在每次调用之后，将信息（名称，数字，日期和持续时间）插入到数组列表中。
recentCalls.add(new Recent(aName, aDate, aNumber, "0"));
（0表示持续时间的秒数。仍未完成。）
它会暂时“保存”在应用程序中，当应用程序被完全杀死（或崩溃）时，一切都将被清空。
我考虑过在SharedPreferences中保存数组列表。
但是由于我们要将最近限制为100，这将太大了。
我读过这个：Android Storage Options 无论哪种方式，我仍然从手机本身获取所有通话记录，以进行测试。
我的问题是：

这是我目前的通话方式。 （注释掉了东西，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();
通话功能：
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 {

CharSequence text = getResources().getText(R.string.keypadViewToastEmptyNumber);
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);

}
}
需要将其插入“列表”并在“最近”选项卡上显示。 我花了几个小时试图解决这个问题，没有进展。提前谢谢！
编辑＃2
public View getView(int position, View convertView, ViewGroup parent){
//Make sure we have a view to work with
View itemView = convertView;
if(itemView == null)
{
itemView = getLayoutInflater().inflate(R.layout.recents_view, parent,false);
}
Recent currentCall = recentCalls.get(position);
TextView nameText = (TextView) itemView.findViewById(R.id.tvRecentName);
nameText.setText(currentCall.getName());
TextView numberText = (TextView) itemView.findViewById(R.id.tvRecentNumber);
numberText.setText(currentCall.getPn());
TextView dateText = (TextView) itemView.findViewById(R.id.tvRecentDate);
dateText.setText("" + currentCall.getDate());
TextView durationText = (TextView) itemView.findViewById(R.id.tvRecentDuration);
durationText.setText("" + currentCall.getDuration());
return itemView;
// return super.getView(position, convertView, parent);
}
}
所以这是“最近”标签的视图。 .getDate / .getDuration等被改变了，“新的”应该是什么？所以基本上读了
答案 0 :(得分：2)
我将做的是以下内容：
java.io.File到本地（/data/data/f.q.c.n/files/recents）文件FileOutputStream到它ArrayList<Recent>的元素写入文件
String.getBytes）long（自纪元以来）int long和int是固定大小的，因此可以轻松阅读然后，当然，你在启动时反向做同样的事情，重建那个ArrayList。
有人将此方法称为受控二进制序列化。当然，你可以让它更容易，但它并不是很难做到，你摆脱了所有反射（这可能会在早期的Android设备上有可怕的性能）。这是我能想到的最快（最顺畅）的方法。
我没有选择标准序列化，因为它很糟糕（反射和元数据吨）。
请注意，SharedPreferences已成功（ab-）用于存储比您更大的数据。
