use Intent in Kotlin-CodePudding

When we want to move to another Activity using Intent in Kotlin, it gives this error.

In Intent, it doesn't recognize .java after ::class

look:

And when I delete .java, Intent gives an error

Note: My problem was not solved with Invalidate Caches / Restart... option in File

I don't know where the problem is. please help me.

Kinda strange because it seems good to me. Try this.

Remove the lateinit and declare it directly when you need it, maybe it will solve the problem.

val intent = Intent(this, LauncherActivity::class.java)

I don't think the this@KotlinActivity is needed in this case.
Let me know if this fix it

UPDATE

Are you sure the findViewById<TextView>... is correct ? Shouldn't it has a declaration before ? Like

val view = findViewById<>...

CodePudding user response：

The solution is:

In build.gradle (:app) file, in dependencies, you should change appcompat version to 1.4.2.

befor error:

dependencies {
    implementation 'androidx.appcompat:appcompat:1.5.0'
    ...
}

And when I changed the version to 1.4.2, the problem was solved

dependencies {
    implementation 'androidx.appcompat:appcompat:1.4.2'
    ...
}

And make sure the kotlin version is 1.5.0
