我要评论如下代码是监听电话的状态，代码简单不做介绍直接看代码：
复制代码 代码如下:
private boolean mresumeaftercall = false;
private phonestatelistener mphonestatelistener = new phonestatelistener() {
@override
public void oncallstatechanged(int state, string incomingnumber) {
if (state == telephonymanager.call_state_ringing) {
audiomanager audiomanager = (audiomanager) getsystemservice(context.audio_service);
int ringvolume = audiomanager
.getstreamvolume(audiomanager.stream_ring);
if (ringvolume > 0) {
mresumeaftercall = (player.isplaying() || mresumeaftercall);
try {
stub.pause();
} catch (remoteexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
}
} else if (state == telephonymanager.call_state_offhook) {
// pause the music while a conversation is in progress
mresumeaftercall = (player.isplaying() || mresumeaftercall);
try {
stub.pause();
} catch (remoteexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
} else if (state == telephonymanager.call_state_idle) {
// start playing again
if (mresumeaftercall) {
// resume playback only if music was playing
// when the call was answered
try {
stub.resume();
} catch (remoteexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
mresumeaftercall = false;
}
}
}
};
使用的时候呢，就在service 的oncreate 里面添加，如下：
复制代码 代码如下:
public void oncreate() {
player = new mediaplayer();
super.oncreate();
telephonymanager tmgr = (telephonymanager) getsystemservice(context.telephony_service);
tmgr.listen(mphonestatelistener, phonestatelistener.listen_call_state);
intentfilter filter = new intentfilter();
filter.addaction(servicecmd);
filter.addaction(pause_action);
receiver = new musicservicereceiver();
registerreceiver(receiver, filter);
}
在ondestroy 里面删除就可以了
复制代码 代码如下:
public void ondestroy() {
// log.e(tag, "ondestroy" +player.isplaying() );
// system.out.println("ondestroy");
unregisterreceiver(receiver);
player.release();
player = null;
telephonymanager tmgr = (telephonymanager) getsystemservice(context.telephony_service);
tmgr.listen(mphonestatelistener, 0);
super.ondestroy();
}
