App crashes when I press the textview

I have the following TextView

<TextView
    android:id="@+id/LoginlinkLabel"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical center_horizontal"
    android:autoSizeMaxTextSize="45sp"
    android:autoSizeMinTextSize="15sp"
    android:autoSizeStepGranularity="2sp"
    android:text="@string/Loginlink"
    android:textAlignment="center"
    android:textSize="15sp"
    android:onClick="loginlinkLabelonClick"
    android:clickable="true"/>

And this function

fun loginlinkLabelonClick(context:Context)
{
    val urlString="http://www.google.gr"
    val intent = Intent(Intent.ACTION_VIEW,Uri.parse(urlString)) intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    intent.`package`="com.android.chrome"
    try
    {
        context.startActivity(intent)
    }
    catch(ex:ActivityNotFoundException)
    {
        intent.`package`= null
        context.startActivity(intent)
    }
}

The error message:

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.reviewer.reviewer, PID: 27809 java.lang.IllegalStateException: Could not find method loginlinkLabelonClick(View) in a parent or ancestor Context for android:onClick attribute defined on view class android.support.v7.widget.AppCompatTextView with id 'LoginlinkLabel' at android.support.v7.app.AppCompatViewInflater$DeclaredOnClickListener.resolveMethod(AppCompatViewInflater.java:423) at android.support.v7.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:380) at android.view.View.performClick(View.java:6291) at android.view.View$PerformClick.run(View.java:24931) at android.os.Handler.handleCallback(Handler.java:808) at android.os.Handler.dispatchMessage(Handler.java:101) at android.os.Looper.loop(Looper.java:166) at android.app.ActivityThread.main(ActivityThread.java:7425) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.Zygote$MethodAndArgsCaller.run(Zygote.java:245) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:921)

But as soon as I tap the textview the application crashes and I can't seem to find what's wrong. I'm new to Java, kotlin and Android studio. I had a previous experience with visual studio and c# and Java / kotlin feels a bit strange

Now I'm really trying to figure out how to open urls, but I'm having trouble getting it to work

Usually when you have a click method in the xml, the argument for the method in kotlin is a view instance, see more here. So your method should look like this:

fun loginlinkLabelonClick(view:View)
{

}
