Change the state of a switch without triggering OnCheckChanged listener

Question

Is there any workaround helps me to programmatically change the state of Switch widget using switch.setChecked(true); without triggering OnCheckedChangedlistener()?

switch.setChecked(true); trigger OnCheckedChangedlistener() automatically but I need it triggered only when the user changes the state manually. So I need to stop
switch.setChecked(true); triggering OnCheckedChangedlistener()

Answer 1

I worked around this problem by using setOnClickListener() instead of setOnCheckedChangeListener(), then I can use isChecked inside the click listener to know whether the Switch is checked or not, e.g.:

switchView.setOnClickListener {
    val isChecked = switchView.isChecked

    // Do something with the check status
}

You can remove that listener first and set it again after.

switch.setOnCheckChangedListener(null);
switch.setChecked(true);
switch.setOnCheckChangedListener(mOnCheckChangedListener);

2 ways:

1. Whenever you change programmatically, maintain a boolean variable and set it to true. In OnCheckedChangeListener(), check if has come from the user or programmatically.

2. (Not recommended) Before you change programmatically, set yourSwtich.setOnCheckedChangeListener(null) to null. Then in next line again set your listener
