Rikka音乐播放器想加入一个百度语音识别功能，求一个借鉴方案或源码。
大致逻辑是：在搜索页加入一个按钮，该按钮跳转到语音识别页面，开始识别，将识别出的文字直接调用搜索功能。（感觉有点难）或者多一个步骤，将识别的文字传递到搜索页面，setText（识别result），然后我点击本页面的搜索按钮。
搜索页，目前做的效果，点击右上角的语音ImageVie跳转到百度语音页面
百度语音识别页面
百度识别API功能activity部分代码，我想要将asRresponse.getBest_result()识别出来的文字直接通过SearchActivity搜索功能搜索歌名或歌曲。
public class SpeechRecognitionActivity extends AppCompatActivity implements EventListener {
protected SearchEditText etSearch;
protected Button startBtn; // 开始
protected Button stopBtn; // 停止
private EventManager asr;//语音识别核心库
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_recording);
# 添加一张gif图片
ImageView asr_gif = (ImageView) findViewById(R.id.img_gif);
Glide.with(this).load(R.drawable.asr).into(asr_gif);
initPermission();
initView();
// 初始化EventEventManager对象
asr = EventManagerFactory.create(this, "asr");
// 注册自己的输出事件类
asr.registerListener(this);
}
……
@Override
public void onEvent(String name, String params, byte[] data, int offset, int length) {
if (name.equals(SpeechConstant.CALLBACK_EVENT_ASR_PARTIAL)) {
// 识别相关的结果都在这里
if (params == null || params.isEmpty()) {
return;
}
if (params.contains("\"final_result\"")) {
// 一句话的最终识别结果
Log.i("asr.event", params);
Gson gson = new Gson();
AsrResponseBean asRresponse = gson.fromJson(params, AsrResponseBean.class);//数据解析转实体bean
if(asRresponse == null) return;
//从日志中，得出Best_result的值才是需要的，但是后面跟了一个中文输入法下的逗号，
if(asRresponse.getBest_result().contains("，")){//包含逗号 则将逗号替换为空格
etSearch.setText(asRresponse.getBest_result().replace('，',' ').trim());//替换为空格之后，通过trim去掉字符串的首尾空格
}else {//不包含
etSearch.setText(asRresponse.getBest_result().trim());
}
}
}
}
}
