Android：在呼叫结束后更新呼叫日志后查询呼叫日志

当呼叫结束时，如何确保在将呼叫信息写入数据库后查询呼叫日志

我正在使用

BroadcastReceiver

和

android.intent.action.PHONE\u STATE

上的intent过滤器查找通话结束，查找手机是否空闲

在此方面的任何帮助都将不胜感激

谢谢

这是一个非常好的答案

请参阅下面的链接

当您看到上面的示例时，您将了解如何获取调用的结束状态，并且您还将记住，在调用结束后，

call\u state\u IDLE

将多次调用，因此您必须在某个位置获取一个静态变量，并且在理想状态下工作之前必须检查该变量值

编辑

Android在其内置数据库中存储呼叫日志信息。 因此，更好的解决方案是，当您的代码在

OFFHOOK

状态之后调用

IDLE

状态时，您可以将所有新的调用日志从内置数据库复制到数据库中，以获取调用日志的信息

您可以使用以下查询从内置数据库检索调用日志信息

Cursor c=context.getContentResolver（）.query（android.provider.CallLog.Calls.CONTENT_URI，null，null，null）

EDIT2

以下是完整的示例

public static void fetchNewCallLogs(Context context) {

        CallLogHelper callLogHelper = new CallLogHelper(context);
        callLogHelper.open();
        Long maxId = callLogHelper.getMaxId();

        Cursor c = context.getContentResolver().query(android.provider.CallLog.Calls.CONTENT_URI, null, "_id > ?", new String[]{String.valueOf(maxId)}, null);
        if(c != null && c.moveToFirst()) {
            while (c.isAfterLast() == false) {
                int _ID = c.getColumnIndex(android.provider.CallLog.Calls._ID);
                int _NUMBER = c.getColumnIndex(android.provider.CallLog.Calls.NUMBER);
                int _DATE =  c.getColumnIndex(android.provider.CallLog.Calls.DATE);
                int _DURATION =  c.getColumnIndex(android.provider.CallLog.Calls.DURATION);
                int _CALLTYPE =  c.getColumnIndex(android.provider.CallLog.Calls.TYPE);
                int _NAME =  c.getColumnIndex(android.provider.CallLog.Calls.CACHED_NAME);
                int _NUMBERTYPE =  c.getColumnIndex(android.provider.CallLog.Calls.CACHED_NUMBER_TYPE);
                int _NEW = c.getColumnIndex(android.provider.CallLog.Calls.NEW);

                String id = c.getString(_ID);
                String number = c.getString(_NUMBER);
                String date = c.getString(_DATE);
                String duration = c.getString(_DURATION);
                String callType = c.getString(_CALLTYPE);
                String name = c.getString(_NAME);
                String numberType = c.getString(_NUMBERTYPE);
                String _new = c.getString(_NEW);

                callLogHelper.createLog(id, number, date, duration, callType, name, numberType, _new, "N");

                c.moveToNext();
            }
        }
        callLogHelper.close();
    }

 => CallLogHelper is a helper class to communicate with my local database
    => callLogHelper.getMaxId(); will returns the maximum id of call logs in my local database and I am keeping the id in local database and internal database will be same

<receiver android:name=".PhoneStateBroadcastReceiver">
<intent-filter>
    <action android:name="android.intent.action.PHONE_STATE"/>     
</intent-filter>
</receiver>

这是PhoneStateListener类

public class CustomPhoneStateListener extends PhoneStateListener {

Context context;
public CustomPhoneStateListener(Context context) {
super();
this.context = context;
}

@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);

switch (state) {
    case TelephonyManager.CALL_STATE_IDLE:
        // Toast.makeText(context, "CALL_STATE_IDLE", Toast.LENGTH_LONG).show();
        if(UDF.phoneState != TelephonyManager.CALL_STATE_IDLE) {
            UDF.fetchNewCallLogs(context);
        } 
        break;
    case TelephonyManager.CALL_STATE_OFFHOOK:
         //Toast.makeText(context, "CALL_STATE_OFFHOOK", Toast.LENGTH_LONG).show();
        break;
    case TelephonyManager.CALL_STATE_RINGING:
         //Toast.makeText(context, "CALL_STATE_RINGING", Toast.LENGTH_LONG).show();
        endCallIfBlocked(incomingNumber);
        break;

    default:
        break;
}
UDF.phoneState = state;
}

public class PhoneStateBroadcastReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        //UDF.createTablesIfNotExists(context);
        TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        telephonyManager.listen(new CustomPhoneStateListener(context), PhoneStateListener.LISTEN_CALL_STATE);
    }
}

这是广播接收机类

public class CustomPhoneStateListener extends PhoneStateListener {

Context context;
public CustomPhoneStateListener(Context context) {
super();
this.context = context;
}

@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);

switch (state) {
    case TelephonyManager.CALL_STATE_IDLE:
        // Toast.makeText(context, "CALL_STATE_IDLE", Toast.LENGTH_LONG).show();
        if(UDF.phoneState != TelephonyManager.CALL_STATE_IDLE) {
            UDF.fetchNewCallLogs(context);
        } 
        break;
    case TelephonyManager.CALL_STATE_OFFHOOK:
         //Toast.makeText(context, "CALL_STATE_OFFHOOK", Toast.LENGTH_LONG).show();
        break;
    case TelephonyManager.CALL_STATE_RINGING:
         //Toast.makeText(context, "CALL_STATE_RINGING", Toast.LENGTH_LONG).show();
        endCallIfBlocked(incomingNumber);
        break;

    default:
        break;
}
UDF.phoneState = state;
}

public class PhoneStateBroadcastReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        //UDF.createTablesIfNotExists(context);
        TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        telephonyManager.listen(new CustomPhoneStateListener(context), PhoneStateListener.LISTEN_CALL_STATE);
    }
}

这是从内部数据库获取新呼叫日志的功能

public static void fetchNewCallLogs(Context context) {

        CallLogHelper callLogHelper = new CallLogHelper(context);
        callLogHelper.open();
        Long maxId = callLogHelper.getMaxId();

        Cursor c = context.getContentResolver().query(android.provider.CallLog.Calls.CONTENT_URI, null, "_id > ?", new String[]{String.valueOf(maxId)}, null);
        if(c != null && c.moveToFirst()) {
            while (c.isAfterLast() == false) {
                int _ID = c.getColumnIndex(android.provider.CallLog.Calls._ID);
                int _NUMBER = c.getColumnIndex(android.provider.CallLog.Calls.NUMBER);
                int _DATE =  c.getColumnIndex(android.provider.CallLog.Calls.DATE);
                int _DURATION =  c.getColumnIndex(android.provider.CallLog.Calls.DURATION);
                int _CALLTYPE =  c.getColumnIndex(android.provider.CallLog.Calls.TYPE);
                int _NAME =  c.getColumnIndex(android.provider.CallLog.Calls.CACHED_NAME);
                int _NUMBERTYPE =  c.getColumnIndex(android.provider.CallLog.Calls.CACHED_NUMBER_TYPE);
                int _NEW = c.getColumnIndex(android.provider.CallLog.Calls.NEW);

                String id = c.getString(_ID);
                String number = c.getString(_NUMBER);
                String date = c.getString(_DATE);
                String duration = c.getString(_DURATION);
                String callType = c.getString(_CALLTYPE);
                String name = c.getString(_NAME);
                String numberType = c.getString(_NUMBERTYPE);
                String _new = c.getString(_NEW);

                callLogHelper.createLog(id, number, date, duration, callType, name, numberType, _new, "N");

                c.moveToNext();
            }
        }
        callLogHelper.close();
    }

正确。我遇到的问题是，有时，
BroadCastReceiver
会在调用日志更新之前触发，因此当您查询
android.provider.CallLog.Calls.CONTENT\u URI
时，您错过了最近的通话。@gnub当您的手机状态变为“理想”至“挂断”，再变为“理想”状态时，意味着您的通话现在结束，此时您可以查询内部数据库以检索新的通话日志。您可以通过存储与内部数据库中完全相同的行id来保持通话记录，以便您可以查询数据库以获取新的通话记录调用日志大于最后一行id@gnub：您是否找到了处理此竞赛条件的解决方案。我也面临同样的问题。谢谢lot@gnub当前位置你说得对，我在寻找你提到的问题的解决方案时，终于想到了这个问题。作为一个临时且非常难看的修复，我用创建和调用一个新线程的
start（）
替换了您对
fetchNewCallLogs（）的调用，该线程只需休眠500毫秒，然后调用
fetchNewCallLogs（）
。UDF是什么？？有人能解释一下吗？
