使用 Kotlin 将编辑文本的内容发送到电子邮件或文本的按钮

Question

我是 Kotlin 和 Android Studio 的新手，但我决定要编写一个应用程序供我的工作使用。我可以在 Excel 和 VB 中编写我需要的内容，但不幸的是 Android 移动设备不支持宏，因此我想编写一个应用程序。我已经弄清楚了如何创建页面（活动）以及如何在它们之间来回导航（大致），但是，我的最终目标是捕获用户将输入到文本字段中的数据，然后一旦他们单击提交按钮，然后它将他们通过 SMS 输入的数据发送到预定义的 phone 号码 (S)，或者作为文本文件发送到电子邮件地址。任何帮助将不胜感激。请让我知道您需要我做什么 post 以启用任何帮助提前致谢 Code screenshot

发送短信：

val submit: Button = findViewById<Button>(R.id.sub1)
    submit.setOnClickListener {
        val cust: String = custTextField.text.toString()
        val reg: String = regTextField.text.toString()
        val pal: String = palTextField.text.toString()
        val data:String = "CUST : ".plus(cust).plus("\n").plus("REG : ").plus(reg).plus("\n").plus("PAL : ").plus(pal)
        startActivity(getSendSmsIntent("YOUR PHONE NUMBER HERE", data))
    }

发送电子邮件：

val submit: Button = findViewById<Button>(R.id.sub1)
        submit.setOnClickListener {
            val cust: String = custTextField.text.toString()
            val reg: String = regTextField.text.toString()
            val pal: String = palTextField.text.toString()
            val data:String = "CUST : ".plus(cust).plus("\n").plus("REG : ").plus(reg).plus("\n").plus("PAL : ").plus(pal)
            startActivity(Intent.createChooser(getEmailIntent("USER@GMAIL.COM", "SUBJECT", data), "Send mail"))
        }

private fun getSendSmsIntent(phoneNumber: String, content: String?): Intent? {
        val uri = Uri.parse("smsto:$phoneNumber")
        val intent = Intent(Intent.ACTION_SENDTO, uri)
        intent.putExtra("sms_body", content)
        return getIntent(intent, true)
    }

    private fun getEmailIntent(email: String, subject: String?, content: String?): Intent? {
        val intent = Intent(Intent.ACTION_SEND)
        intent.type = "message/rfc822"
        intent.putExtra(Intent.EXTRA_EMAIL, arrayOf(email))
        intent.putExtra(Intent.EXTRA_SUBJECT, subject)
        intent.putExtra(Intent.EXTRA_TEXT, content)
        return getIntent(intent, true)
    }


    private fun getIntent(intent: Intent, isNewTask: Boolean): Intent? {
        return if (isNewTask) intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK) else intent
    }

你的最终 Activity 会是这样的：

import android.content.Intent
import android.net.Uri
import android.os.Bundle
import android.widget.Button
import androidx.appcompat.app.AppCompatActivity


class SecondActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_second)
        //  if(ActivityCompat.checkSelfPermission(this,Manifest.permission.SEND_SMS)!=PackageManager.PERMISSION_GRANTED)
        val backbut = findViewById<Button>(R.id.backbut)
        backbut.setOnClickListener {
            val intent = Intent(this, MainActivity::class.java)
            startActivity(intent)
        }
        val sub1: Button = findViewById<Button>(R.id.sub1)
        sub1.setOnClickListener {
            val cust: String = cust.text.toString()
            val reg: String = reg.text.toString()
            val pal: String = pal.text.toString()
            val data: String =
                "CUST : ".plus(cust).plus("\n").plus("REG : ").plus(reg).plus("\n").plus("PAL : ")
                    .plus(pal)
            startActivity(getSendSmsIntent("1234567", data))
        }
    }

    fun getSendSmsIntent(phoneNumber: String, content: String?): Intent? {
        val uri = Uri.parse("smsto:$phoneNumber")
        val intent = Intent(Intent.ACTION_SENDTO, uri)
        intent.putExtra("sms_body", content)
        return getIntent(intent, true)
    }
    private fun getIntent(intent: Intent, isNewTask: Boolean): Intent? {
        return if (isNewTask) intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK) else intent
    }
}
