Unity使用Android插件onActivityResult未调用

Question

我是准备毕业工作的学生。 我的项目主题是“使用语音识别的VR对话”。

对我来说最难的是语音识别插件。

Android源代码在这里。

public static void promptSpeechInput() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    if(languageNotSet)
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
    else
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, glanguage);
    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, gMaxResults);
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, gQuestion);

    sendMessageToUnity("success!!!");

    try {
        UnityPlayer.currentActivity.startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
    } catch (ActivityNotFoundException a) {

    }
}

public static void sendMessageToUnity(String message){
    UnityPlayer.UnitySendMessage("Main Camera", "receiveFromAndroid", message);
}

在Unity中，方法“ sendMessageToUnity”似乎可以正常工作，因此“ promptSpeechInput”也可以正常工作。（并且还会出现google语音识别对话框。问题->识别结果为空。）

public void sendToUnityFromActivityClass(String message){
    UnityPlayer.UnitySendMessage("Main Camera", "receiveFromActivityClass", message);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    sendToUnityFromActivityClass("onActivityResult 호출!");

    switch (requestCode) {
        case REQ_CODE_SPEECH_INPUT: {
            if (resultCode == RESULT_OK && null != data) {

                String matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS).get(0);
                for (int i = 1; i< data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS).size(); i++){
                    matches = matches + "~"+ data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS).get(i);
                }

                UnityPlayer.UnitySendMessage(objectname, "onActivityResult", matches);

                super.onActivityResult(requestCode, resultCode, data);
            }
        }
    }
}

我认为未调用“ onActivityResult”。

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.admin.testtts">

    <uses-permission android:name="android.permission.RECORD_AUDIO"></uses-permission>
    <application>
        <activity
            android:name=".ActivityClass"
            android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">>
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

而且，SDK版本是26。

我怎么称呼“ onActivityResult”？我认为这似乎是Android的问题。 （也许）

请帮助我！
