android.widget.Switch - on/off event listener?

Question

I would like to implement a switch button, android.widget.Switch (available from API v.14).

Answer 1

there are two ways,

1. using xml onclick view Add Switch in XML as below:

In YourActivity Class (For E.g MainActivity.java)

    Switch toggle; //outside oncreate
    toggle =(Switch) findViewById(R.id.switch1); // inside oncreate

    public void toggle(View view) //outside oncreate
    {
        if( toggle.isChecked() ){
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                start.setBackgroundColor(getColor(R.color.gold));
                stop.setBackgroundColor(getColor(R.color.white));
            }
        }
        else
        {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                stop.setBackgroundColor(getColor(R.color.gold));
                start.setBackgroundColor(getColor(R.color.white));
            }
        }
    }

2. using on click listener

Add Switch in XML as below:

In YourActivity Class (For E.g MainActivity.java)

    Switch toggle; // outside oncreate
    toggle =(Switch) findViewById(R.id.switch1);  // inside oncreate


    toggle.setOnClickListener(new View.OnClickListener() {   // inside oncreate
        @Override
        public void onClick(View view) {

            if( toggle.isChecked() ){
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    start.setBackgroundColor(getColor(R.color.gold));
                }
            }
            else
            {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    stop.setBackgroundColor(getColor(R.color.gold));
                }
            }

        }

    });
