How to check and skip an onClickListener? [duplicate]

Question

Let's say I have a boolean completed that is out of the scope of the onClickListener that is attached to a Button.

What statement can I put inside this if block that will skip the entire code of this Button? (ignoring a messy solution like putting the whole code under the else block)

confirmBttn.setOnClickListener {
    if (completed) {
        *stop or skip the entire button code*
    }

    *code*
}

I am looking for an elegant solution to only stop that listener's block; without stopping the whole program, or using an entire if/else block. Something like a function that simply terminates the particular call for this listener function.

Answer 1

The 'return' keyword will stop the current scope at this point and prevents the code below to run. Other parts of your programm are not affected by this.

confirmBttn.setOnClickListener {
    if (completed) return

    *code*
}
