Mainactivity.kt is not recognizing the ID in Android studio kotlin

Issue

I am trying to run Android app in kotlin. But Mainactivity.kt is not recognizing the ID in Android studio kotlin.

I have tried many ways doing this to solve this error. i even tried to go in build and click on clean project, then, rebuild projects.

but the error wouldn't budge it is still there. i have entered the id of TextView in MainActivity.kt but it still showing in red!

how may i resolve it please help!

Solution

I tested the code for Kotlin version 1.4.1 and it worked perfectly well.

To resolve your error, you can use val tv:TextView = findViewById(R.id.tv_content) and use tv in your code.

Second option is that you classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.20" in your build.gradle file to classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.10"

As stated by @Jimale Abdi -

kotlinx.android.synthetic is no longer a recommended practice. Removing in favour of explicit findViewById.

Hope this helps.
