Android monitoring incoming call display

When we call a phone, we need to monitor the incoming call of the phone number.CodeControl. Let's take a look at the display of incoming calls using the display feature.
 

Package com. Smart;

Import Android. App. activity;
Import Android. content. context;
Import Android. OS. Bundle;
Import Android. telephony. phonestatelistener;
Import Android. telephony. telephonymanager;
Import Android. widget. Toast;

Public class main extends activity {

Public class myphonecalllistener extends phonestatelistener {

@ Override
Public void oncallstatechanged (INT state, string incomingnumber ){

Switch (state ){
Case telephonymanager. call_state_offhook:
Toast. maketext (main. This, "In call...", Toast. length_short). Show ();
Break;


Case telephonymanager. call_state_ringing:
Toast. maketext (main. This, incomingnumber, Toast. length_short). Show ();
Break;
}




Super. oncallstatechanged (State, incomingnumber );
}

}

@ Override
Public void oncreate (bundle savedinstancestate ){
Super. oncreate (savedinstancestate );
Setcontentview (R. layout. Main );
Telephonymanager TM = (telephonymanager) getsystemservice (context. telephony_service );
Myphonecalllistener = new myphonecalllistener ();
TM. Listen (myphonecalllistener, phonestatelistener. listen_call_state );

}
}
