【Android】讀取手機簡訊 顯示到自己的 APP 上 範例

在Android中，content://sms/inbox 是一個URI，它表示手機收件箱中的所有短信消息。開發者可以使用此URI來讀取手機上的短信消息，例如用於短信備份、消息提醒等應用場景。

使用此URI，開發者可以查詢收件箱中的所有短信消息，並讀取每個消息的發送者、接收者、時間戳和消息內容等信息。例如，可以使用以下代碼讀取收件箱中的短信消息。

1.Manifest 申請權限

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
build.gradle
buildFeatures {
    viewBinding true
}
MainActivity.kt
class MainActivity : AppCompatActivity() {

    private lateinit var binding: ActivityMainBinding
    private val readPermission = registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions()) {}

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        readPermission.launch(
            arrayOf(
                android.Manifest.permission.RECEIVE_SMS,
                android.Manifest.permission.READ_SMS
            )
        )
    }
}

2.讀取簡訊

MainActivity.kt
private fun querySMS(): MutableList<SMS> {
    val uri = Uri.parse("content://sms/inbox")
    val projection = arrayOf("_id", "address", "body", "date")
    val smsList = mutableListOf<SMS>()

    contentResolver.query(uri, projection, null, null, null)?.apply {
        if (moveToFirst()) {
            do {
                val id = getInt(getColumnIndexOrThrow("_id"))
                val sender = getString(getColumnIndexOrThrow("address"))
                val body = getString(getColumnIndexOrThrow("body"))
                val timestamp = getLong(getColumnIndexOrThrow("date"))
                val dateFormat = SimpleDateFormat("yyyy/MM/dd HH:mm:ss", Locale.TAIWAN)
                val dateTime = dateFormat.format(Date(timestamp))
                smsList.add(SMS(id, sender, body, dateTime))
            } while (moveToNext())
        }
        close()
    }

    return smsList
}

3.簡訊 projection

_id：短信 ID
thread_id：與該條短信相關聯的會話 ID
address：發送者或接收者的電話號碼
person：發送者或接收者在聯系人列表中的 ID
date：短信的時間戳，以毫秒為單位
date_sent：短信發送的時間戳，以毫秒為單位
protocol：短信協議
read：短信是否已讀
status：短信狀態
type：短信類型，1 表示收到的短信，2 表示發送的短信
body：短信內容
