本文介绍了一种使用Kotlin语言在Android应用中监测移动数据状态的方法，包括判断双卡切换时移动数据是否开启，并通过对话框提示用户进行相应操作。

用kotlin 语言Android 双卡切换判断移动数据是否开启

private var telephonyManager: TelephonyManager? = null
private var dialogBuilder: MaterialAlertDialogBuilder? = null
private var dialog: AlertDialog? = null

override fun onResume() {
    super.onResume()
    telephonyManager = getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager?
    telephonyManager!!.listen(myPhoneStateListener, PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);
    dialogBuilder = MaterialAlertDialogBuilder(this)
            .setTitle("温馨提示")
            .setMessage("请打开移动数据，否则可能无法正常使用")
            .setPositiveButton("知道了") { _, _ ->
                closeApp()
            }
            .setNegativeButton("去打开") { _, _ ->
                openMobileData()
            }
            .setCancelable(false)
}

override fun onPause() {
    super.onPause()
    Timber.i("onPause Activity ${javaClass.simpleName}")
    telephonyManager!!.listen(myPhoneStateListener, PhoneStateListener.LISTEN_NONE);
}

val myPhoneStateListener = object : PhoneStateListener() {
    override fun onDataConnectionStateChanged(state: Int,networkType: Int) {
        super.onDataConnectionStateChanged(state)
        //监听流量状态
        BLogUtils.e("VectorBaseActivity", "===========onDataConnectionStateChanged====state==========" + state+"networkType"+networkType)
        if (state == TelephonyManager.DATA_DISCONNECTED&&networkType == 20) {
            //移动数据关闭
            dialog = dialogBuilder!!.show()
        } else if(state == TelephonyManager.DATA_DISCONNECTED&&networkType == 13) {
            //移动数据开启  副卡
            if (dialog != null) {
                dialog!!.dismiss()
            }
        } else if(state == TelephonyManager.DATA_CONNECTED){
            //移动数据开启  主卡
            if (dialog != null) {
                dialog!!.dismiss()
            }
        }
    }
}
