android apk内语音控制

最近的音频播放项目要求应用内支持语音控制

用的是讯飞的，大概整理一下作为笔记：

首先在lib目录下引入：XiriScene.jar和XiriFeedback.jar

然后在bulid.gradle文件中加入：

implementation files('libs\xiriScene.jar')
implementation files('libs\xiriFeedback.jar')

接下来是代码：

1.XiriISceneListener.java

package com.mychtech.himalayajs.service;

import android.content.Intent;


public interface XiriISceneListener {
    String onQuery();

    void onExecute(Intent var1);
}

2.XiriManager.java

package com.mychtech.himalayajs.service;

import android.content.Context;
import android.content.Intent;
import android.util.Log;

import com.iflytek.xiri.Feedback;

import org.json.JSONException;
import org.json.JSONObject;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class XiriManager implements XiriISceneListener {
    private static XiriManager mInstance = null;
    private XiriScene mScene;
    private Feedback mFeedback;
    private String mSceneJson;
    private Context mContext = null;
    private IXiriManager mIXiriManager = null;

    public static XiriManager getInstance() {
        synchronized (XiriManager.class) {
            if (mInstance == null) {
                mInstance = new XiriManager();
            }
        }
        return mInstance;
    }

    public void onCreate(Context context, IXiriManager iXiriManager) {
        mIXiriManager = iXiriManager;
        mContext = context;
        mScene = new XiriScene(context);
        mFeedback = new Feedback(context);
        mScene.init(this);
        Log.i("XiriManager", "XiriManager add XiriManager oncreate....");
    }

    public void onResume() {
        //初始化Scene,在界面显示的时候才可调用
        mScene.init(this);
        Log.i("XiriManager", "XiriManager add XiriManager onResume....");
    }
    public void onPause() {
        //释放Scene，在界面消失的时候调用
        mScene.release();
        Log.i("XiriManager", "XiriManager add XiriManager onPause....");
    }

    @Override
    public String onQuery() {
        return regiestScene();
    }

    @Override
    public void onExecute(Intent intent) {
        mFeedback.begin(intent);
        //判断是否有注册的场景
        Log.i("XiriManager", "XiriManager add _scene = " + intent.hasExtra("_scene"));
        if (intent.hasExtra("_scene") && intent.getStringExtra("_scene")
                .equals("com.mychtech.himalayajs.activity.AudioDetailActivity")) {
            if (intent.hasExtra("_command")) {    //需注意，此处是_command，不是场景注册时候的_commands，千万别搞错了！
                String commands = intent.getStringExtra("_command");
                Log.i("XiriManager", "XiriManager add commands:" + commands);

3. XiriScene.java

                        Log.d("SCENE_TIME", "fromIntent sceneId " + sceneId);

                        try {

    }

    public void release() {
        this.mContext.unregisterReceiver(this.mReceiver);
    }
}

然后在 main目录下新建一个名为“XiriSceneText.json”的文件

XiriSceneText.json的内容如下：

{
    "_commands": {
        "key1": [
            "打开",
            "打开详情"
        ],
        "key2": [
            "$P(_PLAY)"
        ],
        "key3": [
            "$P(_PAGE)"
        ],
        "key4": [
            "$W(video)"
        ],
        "key5":[
            "$P(_EPISODE)"
        ],
        "key6":[
            "$P(_SELECT)"
        ],
        "key7":[
            "退出当前页面"
        ]
    },
    "_fuzzy_words": {
        "video": [
        ]
    },
    "_scene": "com.mychtech.himalayajs.activity.AudioDetailActivity"
}

 然后在AudioDetailActivity的onCreate方法里面调用：

XiriManager.getInstance().onCreate(this, new XiriManager.IXiriManager() {
            @Override
            public void setXiriToJs(String key, String action, String params) {
                //预定义槽 $P(_PLAY)  $P(_PAGE) $P(_EPISODE) $P(_SELECT)
                mKey = key;
                Log.i(TAG, "setXiriToJs--key:" + key + "---action:" + action + "---param:" + params);
                if (null != mMediaPlayer) {
                    switch (key) {
                        case "$P(_PLAY)":// 播放控制
                            if ("PAUSE".equals(action)) {
                                if (mMediaPlayer.isPlaying()) {
                                    ivPlay.setImageResource(R.drawable.bg_play_slt);
                                    mMediaPlayer.pause();
                                }
                            } else if ("PLAY".equals(action)) {
