    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        buttonRight = (Button) findViewById(R.id.btnRight_activity_main);
        buttonLeft = (Button) findViewById(R.id.btnLeft_activity_main);

        buttonLeft.setOnClickListener(this);
        buttonRight.setOnClickListener(this);
    }

    // variable to track event time
    private long mLastClickTime = 0;

    @Override
    public void onClick(View v) {
        // Preventing multiple clicks, using threshold of 1 second
        if (SystemClock.elapsedRealtime() - mLastClickTime < 1000) {
           return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();
        pressedOnClick(v);
    }

    public void pressedOnClick(View v){
        switch (v.getId()){
            case R.id.btnLeft_activity_main:
                showToast("Left_activity_main");
                break;

            case R.id.btnRight_activity_main:
                showToast("Right_activity_main");
                break;
        }

    }
