私は Android アプリケーションのテキスト読み上げに取り組んでいます。Text to Speech が完了したときに呼び出されるメソッドを見つけることに混乱しています。次のメソッドを呼び出そうとしましたが、完了したメソッドが呼び出されませんでした。次のコードを調べて、提案してください。

 tts= new TextToSpeech(MainActivity.this, new OnInitListener() {

         @Override
         public void onInit(int status) {

             tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {

                @Override
                public void onUtteranceCompleted(final String utteranceId) {
                            System.out.println("Completed");

                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                        //UI changes
                        }
                    });
                }
            });

         }
        });

私に提案してください。API レベル 17 を使用しています。

編集：

最小 API レベルは 12 です。

そして、コンソールに次のエラーが表示されました。

The problem is not in onUtteranceComplete function , its most likely get called, but you're trying to print the output to System.out , please use android.utils.Log("tag", "success") instead and see what happens.

Also You need to set UtteranceID to get onUtteranceComplete to work before calling tts.speak method. so to sum up:

            TextToSpeech tts= new TextToSpeech(MainActivity.this, new OnInitListener() {

         @Override
         public void onInit(int status) {

             tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {

                @Override
                public void onUtteranceCompleted(final String utteranceId) {
                            System.out.println("Completed");

                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                        //UI changes
                        }
                    });
                }
            });

         }
    });
    Map<String,String> ttsParams = new HashMap<String, String>();
    ttsParams.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,
            MainActivity.this.getPackageName());

    mTts.speak(text, TextToSpeech.QUEUE_FLUSH, ttsParams);

And the exception you're getting has nothing to do with the onUtteranceComplete method, if it is because of tts engine most likely you're not requesting to destroy your instance when finishing your activity.

To fix that add

@Override
onDestroy(){
super.onDestroy();
mTts.shutdown(); //mTts is your TextToSpeech Object
}

To your activity class

APIレベル15から、setOnUtteranceProgressListener代わりに使用する必要がありますsetOnUtteranceCompletedListener

公式ドキュメントを確認する

これを試して：

if(tts.myTTS.isSpeaking())

ブール値を取得します。
