如何在Kotlin/Android中从收件箱到对话选项卡

Question

我已经编写了收件箱活动和对话活动的代码，但是当用户单击" Inbox"选项卡中的任何消息时，不明白如何移动到对话选项卡..？**注意：**我的应用程序是一个离线SMS应用

我已经搜索了很多，但什么也没找到。

收件箱活动

class InBox : AppCompatActivity() {

    private val requestContactSms: Int = 3
    private val requestReceiveSms: Int = 1
    private val requestReadSms: Int = 2
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.readsms)
        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.SEND_SMS) !=
            PackageManager.PERMISSION_GRANTED
        ) {
            ActivityCompat.requestPermissions(
                this, arrayOf(android.Manifest.permission.SEND_SMS, android.Manifest.permission.READ_CONTACTS),
                requestReadSms)
        } else {
            refreshSmsInbox()
        }
        if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.READ_CONTACTS) !=
            PackageManager.PERMISSION_GRANTED
        ) {
            ActivityCompat.requestPermissions(
                this, arrayOf(android.Manifest.permission.READ_CONTACTS),
                requestContactSms
            )
        } else {
            refreshSmsInbox()

            ActivityCompat.requestPermissions(
                this, arrayOf(android.Manifest.permission.RECEIVE_SMS, android.Manifest.permission.READ_CONTACTS),
                requestReceiveSms
            )
        }
    }

    override fun onRequestPermissionsResult(

                    val parser = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss") //Input date formate
                    val formatter = SimpleDateFormat("HH:mm a") //Output date formate
                    val formattedDate = formatter.format(parser.parse("2018-12-14T09:55:00"))
                    do {
                        val dateString = it.getString(dateID)
                        // val sms = SmsData(getContactName(this,it.getString(nameID!!.toInt()).toString()),it.getString(messageID),
                        //SimpleDateFormat("hh:mm a").format(Date(dateString.toLong()).toString())
                        val sms = SmsData(getContactName(this,it.getString(nameID!!.toInt()).toString()),it.getString(messageID),
                            SimpleDateFormat("hh:mm a").format(Date(dateString.toLong()).toString())
                        )
                        smsList.add(sms)
                    } while (it.moveToNext())
                    it.close()

                val adapter = ListAdapter(this, smsList)

            }
            Log.d("Inbox","contactName $contactName for $phoneNumber")
            return contactName;
        }
}

listAdapter class

class ListAdapter (val context: Context, val list : ArrayList<SmsData>): BaseAdapter(){
    @SuppressLint("ViewHolder", "SimpleDateFormat")
    override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
        val view = LayoutInflater.from(context).inflate(R.layout.rowlayout,parent,false)
        list[position].senderName?.let{
            view.sender.text = it.substring(0,1).toUpperCase()
        }
        view.sms_sender.text = list[position].senderName
        view.sms_message.text = list[position].message
        val date: Date = Date(list[position].date)
        val dateFormat = SimpleDateFormat("hh:mm a")
        view.sms_date.text = dateFormat.format(date)
        return  view
    }
    override fun getItem(position: Int): Any {
        return list[position]
    }
    override fun getItemId(position: Int): Long {
        return position.toLong()
    }
    override fun getCount(): Int {
       return list.size
    }
}

对话活动

private const val TAG = "MainActivity1"
class MainActivity1 :AppCompatActivity(){
    private val requestReceiveSms: Int = 1
    private val requestSendSms: Int = 2
    private var mMessageRecycler: RecyclerView? = null
    private var mMessageAdapter: MessageAdapter? = null
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
          seupRecycler()

        btnSend.setOnClickListener {
            if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.SEND_SMS) !=
                PackageManager.PERMISSION_GRANTED
            ) {
                ActivityCompat.requestPermissions(
                    this, arrayOf(android.Manifest.permission.SEND_SMS),

        }
    }
    private fun seupRecycler() {
        mMessageRecycler = this.reyclerview_message_list as RecyclerView
        mMessageAdapter = MessageAdapter(this)
        val layoutManager = LinearLayoutManager(this)
        layoutManager.orientation = RecyclerView.VERTICAL
    }
    override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>,
                                                grantResults: IntArray) {

            Toast.makeText(this,"SMS Sent",Toast.LENGTH_SHORT).show()

        }

预期：

当用户单击Inbox选项卡中的任何消息时，移动到对话选项卡。

实际：

单击时什么都不会发生。

您需要在适配器类中调用startActivity

class ListAdapter (val context: Context, val list : ArrayList<SmsData>): BaseAdapter(){
@SuppressLint("ViewHolder", "SimpleDateFormat")
override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
    val view = LayoutInflater.from(context).inflate(R.layout.rowlayout,parent,false)
    list[position].senderName?.let{
        view.sender.text = it.substring(0,1).toUpperCase()
    }
    view.sms_sender.text = list[position].senderName
    view.sms_message.text = list[position].message
    val date: Date = Date(list[position].date)
    val dateFormat = SimpleDateFormat("hh:mm a")
    view.sms_date.text = dateFormat.format(date)
    view.clickListener { View -> 
        val intent = MainActivity1.newIntent(context, MainActivity1.class)
        context.startActivity(intent)
    }       
    return  view
}
override fun getItem(position: Int): Any {
    return list[position]
}
override fun getItemId(position: Int): Long {
    return position.toLong()
}
override fun getCount(): Int {
   return list.size
}}
