Add listener to switch in action bar

I have added switch to action bar of an activity like this switch layout.xml is ``` <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="match_parent" android:orientation="horizontal" > <Switch android:id="@+id/switch1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="" /> </RelativeLayout> ``` Menu.xml is ``` <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/action_settings" android:orderInCategory="100" android:showAsAction="never" android:title="@string/action_settings"/> <item android:id="@+id/myswitch" android:title="" android:showAsAction="always" android:actionLayout="@layout/switch_layout" /> </menu> ``` in java file i have this code ``` public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.Menu, menu); switch1 = (Switch) findViewById(R.id.switch1); if(switch1 == null){ Toast.makeText(this, "Null", Toast.LENGTH_SHORT).show(); } // switch1.setOnCheckedChangeListener(this); return true; } public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { Toast.makeText(this, "Monitored switch is " + (isChecked ? "on" : "off"), Toast.LENGTH_SHORT).show(); } public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.switch1: Toast.makeText(this, "here", Toast.LENGTH_SHORT).show(); break; default: break; } return super.onOptionsItemSelected(item); } ``` It is showing null in toast.
