无法在Android中的Kotlin中的活动之间传递数据

Question

我将第一个屏幕传递的数据为：

 /** Start Events Schedule screen **/
    private fun startEventScheduleForTodaysEvents(eventCode: String?) {
        val eventsIntent = Intent(this, ActEventSchedule::class.java)
        intent.putExtra(Keys.EVENT_CODE,"data")
        startActivity(eventsIntent)
    }

第二个屏幕，我收到的数据为：

/** Get data from previous screen **/
    private fun getDataFromPrevScreen() {

        val extras = intent.extras
        if (extras != null) {
            eventCode = extras.getString(Keys.EVENT_CODE)
        }

    }

我无法接收数据

{EDIT}

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.act_event_schedule)
        //Get data from previous screen
        getDataFromPrevScreen()
    }

Answer 1

您要传递一种意图并将数据添加到不同的意图

 val eventsIntent = Intent(this, ActEventSchedule::class.java)
 intent.putExtra(Keys.EVENT_CODE,"data")              // You are adding data to intent
 startActivity(eventsIntent)          // you are passing events Intent

您的代码应如下

val eventsIntent = Intent(this, ActEventSchedule::class.java)
eventsIntent.putExtra(Keys.EVENT_CODE,"data")
startActivity(eventsIntent)
