如何从设备本地联系人中仅获取手机号，排除WhatsApp、Duo等号码

核心原理 #

第三方通讯应用（如WhatsApp、Google Duo）添加的联系人号码，会在ContactsContract.CommonDataKinds.Phone.DATA_SET字段中标记专属应用ID（例如"com.whatsapp"），而设备本地原生手机号的该字段值为空或null。利用这一特性即可精准过滤。

修改后的查询代码 #

直接替换你原有的查询逻辑，添加过滤条件：

// 只查询需要的字段，减少内存占用
val projection = arrayOf(
    ContactsContract.CommonDataKinds.Phone.NUMBER,
    ContactsContract.CommonDataKinds.Phone.DATA_SET
)

// 筛选条件：指定联系人ID + DATA_SET为空/Null（排除第三方应用号码）
val selection = """
    ${ContactsContract.CommonDataKinds.Phone.CONTACT_ID} = ? 
    AND (${ContactsContract.CommonDataKinds.Phone.DATA_SET} IS NULL 
         OR ${ContactsContract.CommonDataKinds.Phone.DATA_SET} = '')
""".trimMargin()

val phones: Cursor? = contentResolver.query(
    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
    projection,
    selection,
    arrayOf(contactId),
    null
)

// 遍历结果，获取本地手机号
phones?.use { cursor ->
    while (cursor.moveToNext()) {
        val numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)
        val localPhoneNumber = cursor.getString(numberIndex)
        // 处理你的本地手机号
    }
}

可选：按号码类型精准筛选 #

如果只需要移动手机号，可在筛选条件中加入类型判断：

val selection = """
    ${ContactsContract.CommonDataKinds.Phone.CONTACT_ID} = ? 
    AND (${ContactsContract.CommonDataKinds.Phone.DATA_SET} IS NULL 
         OR ${ContactsContract.CommonDataKinds.Phone.DATA_SET} = '')
    AND ${ContactsContract.CommonDataKinds.Phone.TYPE} = ${ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE}
""".trimMargin()

若需要兼容住宅、工作等原生号码类型，可使用IN条件：

AND ${ContactsContract.CommonDataKinds.Phone.TYPE} IN (
    ${ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE},
    ${ContactsContract.CommonDataKinds.Phone.TYPE_HOME},
    ${ContactsContract.CommonDataKinds.Phone.TYPE_WORK}
)
