Switch button, disable change state onClick

I want to use a switch button but I want to disable the change status on click, let this change only to the drag option. I try to set onclick listener to do nothing but when I click on the button always change the state.

Some one know to disable the change status onClick?

4 years later found a solution pretty clean and easy for this usecase :

Create your custom switch and override performClick(), that part allows to avoid CompoundButton to react at click :

class CustomSwitch @JvmOverloads constructor(
    context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) : SwitchMaterial(context, attrs, defStyleAttr) {

    override fun performClick(): Boolean {
        return false
    }
}

Second part is to forbid TextView inheritance to react at click and for that just add this to your XML :

android:textIsSelectable="false"

Using a switch widget you will have to create your customSwitch class and override the onTouchEvent method to return true when you detect a click:

public boolean onTouchEvent(MotionEvent ev) {
    boolean response;
    switch (ev.getAction()){
        case MotionEvent.ACTION_DOWN:
            x = ev.getX();
            response = super.onTouchEvent(ev);
            break;
        case MotionEvent.ACTION_UP:
            response = Math.abs(x - ev.getX()) <= 10 || super.onTouchEvent(ev);
            break;
        default:
            response = super.onTouchEvent(ev);
            break;
    }
    return response;
}

The number 10 is a tolerance value as some devices report a movement event of 3 or 6 pixels or so instead of a click, so with this you control: 10 pixels or less is click (and ignore it) or more distance is considered movement and let this movement pass trought normal switch behaivor.

Declare x as a class level variable, default value is 0. MotionEvent.ACTION_DOWN is allways called first so you will have x with the starting value on the X axis of the MotionEvent.

If you want to only change the state of the switch with swipe do the following:

 switchbutton = view.findViewById(R.id.switch2);
    switchbutton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            switchbutton.setChecked(!switchbutton.isChecked());
        }
    });

//onClickListener
public void tglOnClick(View v) {
    ToggleButton tgl = (ToggleButton) v;

    //do something based on toggle status after clicking
    if (tgl.isChecked())
        //do something
    else
        //do something else

    //revert button state so that it can be controlled by some external logic
    tgl.setChecked(!tgl.isChecked());

}

This worked for me. In my case, the clicking the toggle button sent a request to a service, and if the service replied "OK", the message handler set the correct state of the toggle button.
