如何在Android中重用onClickListener

Question

I'm having one activity containing many buttons and each button performs different task. Since, I'm using push notifications to perform separate task every time for different notification, What is the best way to simulate the onClick Event.

One way I thought is using function. Writing separate function and calling it in onClickListener. Is there any other way to achieve the objective?

  btnengg.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            if (netconnect(null)==1)
            {
                w.loadUrl("myurl1");
                wtshare.setVisibility(View.VISIBLE);
            }

            else
            {
            mInterstitialAd.show();

            pbb.setVisibility(View.VISIBLE);
            fadView.setVisibility(View.INVISIBLE);
            w.loadUrl("myurl2");
                requestNewInterstitial();

            }}
    });

Assign OnClickListener to a field and set it as click listener and based on button Id perform relative action

OnClickListener buttonClickListener = button -> {
    switch (button.getId()) {
        case R.id.button1:
            break;
    }
};

button.setOnClickListener(buttonClickListener);

In case you are asking how to initiate click action programmatically, you can button.performClick();
