Call Status MonitoringCodePreviously, I posted the appconstant class, which is only used to store the playback control information. Some netizens said they would like to take a look, so I 'd like to paste it here.

 

 



Package com. WWJ. Sb. Domain;

/ * *
* apply the constant class

Public class AppConstant {
Public class PlayerMsg {
Public static final int PLAY_MSG = 1; / / play
Public static final int PAUSE_MSG = 2; / / pause
Public static final int STOP_MSG = 3; / / stop
Public static final int CONTINUE_MSG = 4; / / to continue
Public static final int PRIVIOUS_MSG = 5; / / a
Public static final int NEXT_MSG = 6; / / a
Public static final int PROGRESS_CHANGE = 7; // schedule change
Public static final int PLAYING_MSG = 8; // playing now
}
}

 

Well, we should continue to improve the simplified and beautiful music players of Xiao Wu, because a good application software should take into account various situations. For the music player, if a call is made during the playing of music, it may be "people who will never call you". If your music is still playing in the background at this time, I think you will go crazy, people who will never call you may never call you. This is just a joke, so you have to consider this situation. As long as you call, the player should be able to pause so that you can make a call. The following implementation is very simple and I will not explain it much. I will directly go to the Code:

1. Add Permissions

 

 



<!--</span--> -- read the phone status permission -->
< USES - the permission of the android: name = "android. Permission. READ_PHONE_STATE" / >
< USES - the permission of the android: name = "android. Permission. PROCESS_OUTGOING_CALLS" / >

2. Get the telephonymanager object and call the listen method to listen to the incoming call status.

 

 

// add call listening event
TelephonyManager telManager = (TelephonyManager) getSystemService(context.telephony_service); // access system services
TelManager. Listen (new MobliePhoneStateListener (),
PhoneStateListener. LISTEN_CALL_STATE);

3. Listener class

 

 

/ * *
*
* @ author WWJ
* phone listener class
* /
Private class MobliePhoneStateListener extends PhoneStateListener {
@ Override
Public void onCallStateChanged(int state, String incomingNumber) {
The switch (state) {
Case telephonymanager.call_state_idle: // hung state
Intent Intent = new Intent(playeractivity.this, playerservice.class);
PlayBtn. SetBackgroundResource (R.d rawable. Play_selector);
Intent. SetAction (" com. WWJ. Media. MUSIC_SERVICE ");
Intent. PutExtra (" MSG ", AppConstant. PlayerMsg. CONTINUE_MSG); // keep playing the music
StartService (intent);
IsPlaying = false;
IsPause = true;
Break;
Case telephonymanager.call_state_offhook: // call status
Case telephonymanager.call_state_ringing: // ringing state
Intent intent2 = new Intent(playeractivity.this, playerservice.class);
PlayBtn. SetBackgroundResource (R.d rawable. Pause_selector);
Intent2. SetAction (" com. WWJ. Media. MUSIC_SERVICE ");
Intent2. PutExtra (" MSG ", AppConstant. PlayerMsg. PAUSE_MSG);
StartService (intent2);
IsPlaying = true;
IsPause = false;
Break;
Default:
Break;
}
}
}
