您可以使用此代码段向现有呼叫日志内容提供程序添加新记录：

public static void insertPlaceholderCall(ContentResolver contentResolver, String number){
    ContentValues values = new ContentValues();
    values.put(CallLog.Calls.NUMBER, number);
    values.put(CallLog.Calls.DATE, System.currentTimeMillis());
    values.put(CallLog.Calls.DURATION, 0);
    values.put(CallLog.Calls.TYPE, CallLog.Calls.OUTGOING_TYPE);
    values.put(CallLog.Calls.NEW, 1);
    values.put(CallLog.Calls.CACHED_NAME, "");
    values.put(CallLog.Calls.CACHED_NUMBER_TYPE, 0);
    values.put(CallLog.Calls.CACHED_NUMBER_LABEL, "");
    Log.d(TAG, "Inserting call log placeholder for " + number);
    contentResolver.insert(CallLog.Calls.CONTENT_URI, values);
}

记住在清单中添加权限

<uses-permission
    android:name="android.permission.READ_CONTACTS"/>
<uses-permission
    android:name="android.permission.WRITE_CONTACTS"/>

链接的帖子解释得很好，所以我不知道你为什么又问了一遍。您不能修改通话记录，除非您保留自己的数据库或固件。

我准备了一个Kotlin版本，它添加了随机项目，并具有不同的类型：

清单

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.WRITE_CALL_LOG" />

主活动注：我没有处理这里的权限授予。我认为他们被授予。

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

                val phonesList = ArrayList<String>(phoneListSize)

                        sb.append(Random.nextInt(10).toString())
                    phonesList.add(sb.toString())
                }
                Log.d("AppLog", "list of phones to use:${phonesList}")
                try {

                        val number = phonesList.get(Random.nextInt(phonesList.size))
                        Log.d("AppLog", "$i - Inserting call log placeholder for $number")
                        insertPlaceholderCall(contentResolver, number)
                    }
                } catch (e: Throwable) {
                    Log.e("AppLog", "failed:$e")
                    e.printStackTrace()
                }
                Log.d("AppLog", "done")
            }
        }
    }

    companion object {
        fun insertPlaceholderCall(contentResolver: ContentResolver, number: String) {
            val values = ContentValues()
            values.put(CallLog.Calls.NUMBER, number)
            val cal = Calendar.getInstance()
            //go back up to 30 days, in seconds
            cal.add(Calendar.SECOND, -Random.nextInt(30 * 24 * 60 * 1000))
            values.put(CallLog.Calls.DATE, cal.timeInMillis)
            // up to 10 minutes call
            values.put(CallLog.Calls.DURATION, Random.nextInt(60 * 10))
            val type = when (Random.nextInt(4)) {
                0 -> CallLog.Calls.OUTGOING_TYPE
                1 -> CallLog.Calls.INCOMING_TYPE
                2 -> CallLog.Calls.MISSED_TYPE
                3 -> CallLog.Calls.REJECTED_TYPE
                //BLOCKED_TYPE is ignored in the Phone app, for some reason
                4 -> CallLog.Calls.BLOCKED_TYPE
                //VOICEMAIL_TYPE causes an exception of IllegalArgumentException: Uri content://call_log/calls cannot be used for voicemail record. Please set 'allow_voicemails=true' in the uri.
                else -> CallLog.Calls.VOICEMAIL_TYPE
            }
            values.put(CallLog.Calls.TYPE, type)
            values.put(CallLog.Calls.NEW, 1)
            values.put(CallLog.Calls.CACHED_NAME, "")
            values.put(CallLog.Calls.CACHED_NUMBER_TYPE, 0)
            values.put(CallLog.Calls.CACHED_NUMBER_LABEL, "")
            contentResolver.insert(CallLog.Calls.CONTENT_URI, values)
        }
    }
}

虽然文档有点奇怪，因为它说它支持3种类型，但它列出了5种类型：
https://developer.android.com/reference/android/provider/CallLog.Calls#TYPE
由于某种原因，我在尝试使用VOICEMAIL_TYPE时遇到了一个异常：
java.lang.IllegalArgumentException：URI内容：//call_log/calls不能用于语音邮件记录。请在uri中设置“allow_voicemails=true”。
此外，当尝试使用BLOCKED_TYPE时，我无法在Phone应用程序中的任何位置看到该项目。
如果有人能告诉我如何修理它，请告诉我。
