android通话记录的查询与删除

CallLogProvider介绍

系统的通话记录,是通过 ContentProvider 来对外共享的

负责存放呼叫记录的内容提供者源码在 ContactsProvider 项目下:

源码路径:

com/Android/providers/contacts/CallLogProvider.Java

使用到的数据库在:

/data/data/com.android.providers.contacts/databases/contacts2.db 表名:calls

呼叫记录有三种类型:

来电:CallLog.Calls.INCOMING_TYPE (常量值:1)

已拨:CallLog.Calls.OUTGOING_TYPE(常量值:2)

未接:CallLog.Calls.MISSED_TYPE(常量值:3)

查看源码中的声明:

<provider android:name="CallLogProvider"

          android:authorities="call_log"

          android:syncable="false" android:multiprocess="false"

          android:readPermission="android.permission.READ_CONTACTS"

          android:writePermission="android.permission.WRITE_CONTACTS">

provider>

所以当我们需要读取通话记录时需要声明权限:

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

需要写入通话记录时需要声明权限:

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

通话记录操作

查询所有的记录

    /**
     * 查询所有的记录
     */
    private void queryAll() {
        ContentResolver resolver = getContentResolver();
        Cursor cursor = resolver.query(CallLog.Calls.CONTENT_URI, null, null, null, null);
        Log.d(TAG, "call log count:" + cursor.getCount());
        while (cursor.moveToNext()) {
            String callNumber = cursor.getString(cursor.getColumnIndex("number"));
            Log.d(TAG, "call log:" + callNumber);
        }
    }

查询已知号码的记录

ContentResolver resolver = getContentResolver();

resolver.query(CallLog.Calls.CONTENT_URI, null, "number=?", new String[]{"15220000000"}, null);

ps: CallLog.Calls.CONTENT_URI : 等价于:Uri.parse(“content://call_log/calls”)

删除已知号码的记录

/**
     * 删除某个记录
     */
    private void deleteCallLog(String callLog) {
        ContentResolver resolver = getContentResolver();
        int result = resolver.delete(CallLog.Calls.CONTENT_URI, "number=?", new String[] { callLog });
        if (result > 0) {
            Log.d(TAG, "deleted success:" + callLog);
        } else {
            Log.d(TAG, "deleted fail:" + callLog);
        }
    }

查询某一个联系人的所有未接电话记录(按电话号码)

resolver.query(CallLog.Calls.CONTENT_URI, null, "number=? and type=3", new String[]{"15100000000"}, null);

type取值参照上面呼叫记录的三种类型

删除某联系人最近的一次来电

/**
     * 删除某联系人最近的一次来电
     * 
     * @param callLog
     */
    private void deletLastCallLog(String callLog) {
        ContentResolver resolver = getContentResolver();
        Cursor cursor = resolver.query(CallLog.Calls.CONTENT_URI, new String[] { "_id" }, "number=? and (type=1 or type=3)", new String[] { callLog },
                "_id desc limit 1");
        if (cursor.moveToFirst()) {
            int id = cursor.getInt(0);
            resolver.delete(CallLog.Calls.CONTENT_URI, "_id=?", new String[] { id + "" });
        }
    }
