aidl 中通过RemoteCallbackList 运用到的回调机制： service回调 android aidl 回调

发布时间：2024年11月06日 17:57:31分享人:不帅你报警来源:互联网24
说明：我没有写实例代码，直接拿项目中的代码，有点懒了，这里我省略贴出两个aidl文件。

TtsService extends Service

[java]view plaincopy

privatefinalRemoteCallbackList<ITtsCallback>mCallbacks

=newRemoteCallbackList<ITtsCallback>();

[java]view plaincopy

privatefinalandroid.speech.tts.ITts.StubmBinder=newStub(){

publicintregisterCallback(StringpackageName,ITtsCallbackcb){

if(cb!=null){

mCallbacks.register(cb);

mCallbacksMap.put(packageName,cb);

returnTextToSpeech.SUCCESS;

}

returnTextToSpeech.ERROR;

}

publicintunregisterCallback(StringpackageName,ITtsCallbackcb){

if(cb!=null){

mCallbacksMap.remove(packageName);

mCallbacks.unregister(cb);

returnTextToSpeech.SUCCESS;

}

returnTextToSpeech.ERROR;

}

publicintspeak(StringcallingApp,Stringtext,intqueueMode,String[]params){

ArrayList<String>speakingParams=newArrayList<String>();

if(params!=null){

speakingParams=newArrayList<String>(Arrays.asList(params));

}

returnthis.speak(callingApp,text,queueMode,speakingParams);

}

[java]view plaincopy

privatevoiddispatchProcessingCompletedCallback(StringpackageName){

ITtsCallbackcb=mCallbacksMap.get(packageName);

if(cb==null){

return;

}

//Log.i("TtsService","TTScallback:dispatchstarted");

//Broadcasttoallclientsthenewvalue.

finalintN=mCallbacks.beginBroadcast();

try{

cb.processingCompleted();

}catch(RemoteExceptione){

//TheRemoteCallbackListwilltakecareofremoving

//thedeadobjectforus.

}

mCallbacks.finishBroadcast();

//Log.i("TtsService","TTScallback:dispatchcompletedto"+N);

}

[java]view plaincopy

@Override

publicvoidonDestroy(){

super.onDestroy();

//TODOreplacethecalltostopAll()withamethodtoclearabsolutelyallupcoming

//usesofthenativesynth,includingsynthesistoafile,anddeletefilesforwhich

//synthesiswasnotcomplete.

stopAll();

//Unregisterallcallbacks.

mCallbacks.kill();

}

在activity中

[java]view plaincopy

mITtscallback=newITtsCallback.Stub(){

publicvoidprocessingCompleted()throwsRemoteException{

if(listener!=null){

listener.onProcessingCompleted();

}

}

};

result=mITts.registerCallback(mPackageName,mITtscallback);

上面只是一个贴代码没有做任何说明，基本的意思我想大家也能通过代码来看懂。

[java]view plaincopy

//intN=mCallbacks.beginBroadcast();

//try{

//for(inti=0;i<N;i++){

//mCallbacks.getBroadcastItem(i).showResult(mSlot);

//}

//}catch(RemoteExceptione){

//Log(""+e);

//}

//mCallbacks.finishBroadcast();
