DESCRIBE THE ISSUE IN DETAIL: I created an empty view activity using Java; when I created the button, I see there is the warning: "button_count <Button>: Using `android:onClick` on older version of the platform is broken."

The button works fine, but why is the warning there, how can I resolve it? I don't want to suppress the warning.

On stack overflow, It suggests enabling the property android:clickable="true", but nothing changed.

STEPS TO REPRODUCE:
1.<Button
        android:id="@+id/button_toast"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="@android:color/white"
        android:onClick="launchSecondActivity"
        android:text="@string/button_label_SayHello"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.0"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
