Android基于讯飞语音SDK实现语音识别

public class Main extends Activity {

  // 组件
  private Button button = null;
  private TextView result = null;
  private Toast mToast = null;

  // 语音识别
  private final String APP_ID = "这里改成自己的APP_ID";

    super.setContentView(R.layout.main);

    button = (Button) super.findViewById(R.id.button_start);
    result = (TextView) super.findViewById(R.id.editText);

    // 初始化识别
    mToast = Toast.makeText(this, "", Toast.LENGTH_SHORT);
    mToast.setMargin(0f, 0.2f);
    recognizerDialog = new RecognizerDialog(this, "appid=" + APP_ID);
    SpeechUser.getUser().login(this, null, null, "appid=" + APP_ID, loginListener);

    this.button.setOnClickListener(new Btn());

  }

  private class Btn implements OnClickListener {

    @Override
    public void onClick(View v) {

      //MainActivity.this.voice.setImageResource(R.drawable.voicelight);
      recognizerDialog.setListener(mRecoListener);
      recognizerDialog.setEngine(null, "grammar_type=abnf", grammarText);
      recognizerDialog.show();
    }
  }

  // 语音识别用户登录监听器
  private SpeechListener loginListener = new SpeechListener() {

    @Override
    public void onData(byte[] arg0) {
    }

    @Override

    }

    @Override

      } else {
        mToast.setText("登录成功");
        mToast.show();
      }
    }
  };

  // 识别结果回调
