android:layout_width=”match_parent”
android:layout_height=”match_parent”
android:paddingBottom=”@dimen/activity_vertical_margin”
android:paddingLeft=”@dimen/activity_horizontal_margin”
android:paddingRight=”@dimen/activity_horizontal_margin”
android:paddingTop=”@dimen/activity_vertical_margin”
tools:context=”.MainActivity” >
<ToggleButton android:id=”@+id/togglebutton”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:textOn=”WI-FI On”
android:textOff=”WI-FI Off”/>
</RelativeLayout>

package com.example.hellotogglebutton;
import android.os.Bundle;
import android.app.Activity;
import android.widget.Toast;
import android.widget.ToggleButton;
import android.view.View;
import android.view.View.OnClickListener;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ToggleButton togglebutton = (ToggleButton) findViewById(R.id.togglebutton);
togglebutton.setOnClickListener(new OnClickListener(){
public void onClick(View v){
//Perform action on clicks
if (togglebutton.isChecked()){
Toast.makeText(getApplicationContext(),”Checked”, Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(getApplicationContext(), “Not Checked”, Toast.LENGTH_SHORT).show();
}
}
});
}
