Answer 1

ToggleButton extends View, so you can simply use View.setOnClickListener(), like this:

// get your ToggleButton
ToggleButton b = (ToggleButton) findViewById(R.id.myButton);

// attach an OnClickListener
b.setOnClickListener(new OnClickListener()
{
    @Override
    public void onClick(View v)
    {
        // your click actions go here
    }
});

if you haven't imported view . you can use it likeb.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // your click actions go here } }); – Monetary

    this.someToggleButton = (ToggleButton)findViewById(R.id.someToggleButton) ;
    this.someToggleButton.setOnCheckedChangeListener( new OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton toggleButton, boolean isChecked) {
            doSomethingWith(toggleButton, isChecked) ;
        }
    }) ;

I tried this first, but in my case the OnClickListener was actually the correct route to go, because OnCheckedChangedListener gets fired even when you change isChecked programmatically. That was causing undesired side effects when I first loaded the activity and set the initial checked state. – Bozcaada

@Bozcaada Could you not set the initial checked state before setting the onCheckedChangedListener? – Aframe

Answer 3

Use View.setOnClickListener() and Check state of button.

    final ToggleButton tB = (ToggleButton) findViewById(R.id.toggleButton1);
    tB.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            if(tB.isChecked()){
                //Button is ON
                            // Do Something 
            }
            else
            //Button is OFF
                            // Do Something     
        }
    });

why you have used 'final' with ToggleButton. @salman khalid plz explain it – Pronucleus

@LASIAF without final, inside the public void onClick() you won't be able to access tB. – Ranice

Just to add a point not emphasised in the other answers - programatically binding a click handler is a bit heavy on the bolierplate code. As mentioned in the docs, it's only necessary in certain scenarios, such as:

• If the ToggleButton is instantiated at runtime
• If the click behaviour is defined in a Fragment subclass

If the ToggleButton is defined in the layout, it's far simpler and cleaner to bind a handler method there

<ToggleButton 
  android:id="@+id/togglebutton"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:textOn="On"
  android:textOff="Off"
  android:onClick="onToggleClicked"/>

Then only the handler method needs to be defined in the Activity Java

public void onToggleClicked(View view) {
    if(((ToggleButton) view).isChecked()) {
        // handle toggle on
    } else {
       // handle toggle off
    }    
}

Note the method can have any name, but the signature must meet these criteria:

• Must be a public method
• Must return void
• Must take a single argument of type View (this will be the View which was clicked)

simple and straightforward! This should be accepted. – Forbade

Answer 5

To add it from the code, you can do something like:

yourButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
      finish();
    }
  });

However, you can also specify in the XML for your button, which method you want to be associated with the onClick action/event.

mTB = (ToggleButton) findViewById(R.id.toggleButton1);
mTB.setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            // Is the toggle on?
            boolean on = ((ToggleButton) v).isChecked();

            if (on) {
                // Enable here
            } else {
                // Disable here
            }

        }
    });

When posting an answer, try to explain why this fixes this issue, along with the code. – Sourdough

Answer 8

if above codes don't work try

b.setOnClickListener(new View.OnClickListener()
{
    @Override
    public void onClick(View v)
    {
       // your click actions go here

Answer 9

Try setOnCheckedChangeListener method of your ToggleButton class

ToggleButton toggleButton = (ToggleButton) findViewById(R.id.toggleButton);
toggleButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton toggleButton, boolean isChecked) {
        // 
    }
}) ;
