从Android Wear智能手表获取数据到智能手机

Question

我曾为moto360上的Android Wear制作了一些应用程序（步数计、心率、录音机），所有功能都正常，但我不知道如何在手表上保存数据，并在智能手机上访问数据。我已经成功地向手表发送消息，但无法从手表向手机发送数据。我可以在智能手机上保存我的数据，但不知道如何在智能手表上管理它。有人能给我展示一篇教程或一个例子吗？非常感谢！
编辑: 下面的代码用于跟踪Moto360上的心率，它运行良好。我尝试将数据从手表传输到手机，为此我使用了这个教程 -> https://developer.android.com/training/wearables/data-layer/data-items.html
在实现来自Android页面的代码后，我无法在设备上运行该项目！

    public class MainActivity extends Activity implements SensorEventListener {


        private static final String TAG = "MainActivity";
        private TextView mTextViewStepCount;
        private TextView mTextViewStepDetect;
        private TextView mTextViewHeart;
        PutDataMapRequest dataMap = PutDataMapRequest.create("/count");
        GoogleApiClient mGoogleApiClient;

        @Override
        protected void onCreate(Bundle savedInstanceState) {


            getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
            stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
                @Override
                public void onLayoutInflated(WatchViewStub stub) {

                    mTextViewStepCount = (TextView) stub.findViewById(R.id.step_count);
                    mTextViewStepDetect = (TextView) stub.findViewById(R.id.step_detect);
                    mTextViewHeart = (TextView) stub.findViewById(R.id.heart);
                    getStepCount();

                }
            });
        }

        private void getStepCount() {
            SensorManager mSensorManager = ((SensorManager) getSystemService(SENSOR_SERVICE));
            Sensor mHeartRateSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_HEART_RATE);
            Sensor mStepCountSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER);
            Sensor mStepDetectSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_STEP_DETECTOR);

            mSensorManager.registerListener(this, mHeartRateSensor, SensorManager.SENSOR_DELAY_NORMAL);
            mSensorManager.registerListener(this, mStepCountSensor, SensorManager.SENSOR_DELAY_NORMAL);
            mSensorManager.registerListener(this, mStepDetectSensor, SensorManager.SENSOR_DELAY_NORMAL);
        }

        private String currentTimeStr() {
            Calendar c = Calendar.getInstance();
            SimpleDateFormat df = new SimpleDateFormat("HH:mm:ss");
            return df.format(c.getTime());
        }

        public void onAccuracyChanged(Sensor sensor, int accuracy) {
            Log.d(TAG, "onAccuracyChanged - accuracy: " + accuracy);
        }

        public void onSensorChanged(SensorEvent event) {
            if (event.sensor.getType() == Sensor.TYPE_HEART_RATE) {
                String msg = "" + (int) event.values[0];

                mTextViewHeart.setText(msg);
                Log.d(TAG, msg);

            } else if (event.sensor.getType() == Sensor.TYPE_STEP_COUNTER) {
                String msg = "Count: " + (int) event.values[0];
                mTextViewStepCount.setText(msg);
                Log.d(TAG, msg);
            } else if (event.sensor.getType() == Sensor.TYPE_STEP_DETECTOR) {
                String msg = "Detected at " + currentTimeStr();
                mTextViewStepDetect.setText(msg);
                Log.d(TAG, msg);
            } else {
                Log.d(TAG, "Unknown sensor type");
            }
        }
    }

你看过这个吗？http://developer.android.com/training/wearables/data-layer/data-items.html - tyczj

是的，我已经查看了这个链接：http://developer.android.com/reference/com/google/android/gms/wearable/DataItem.html，但我不知道该怎么做。 - Hello-World

那么你具体想要发送什么？ - tyczj

使用音频录制器可以录制声音。我想将此音频文件保存带有时间戳，并且它应该与我的智能手机应用程序中的SQLite同步。 - Hello-World

如果你想发送比几个字符串/数字更大的东西，我建议你使用数据 API。 - Tony Malghem

这段代码帮了我很多忙，希望它也能帮助其他人 :)

Answer 2

你需要使用数据资产。图片示例：

private static Asset createAssetFromBitmap(Bitmap bitmap) {
    final ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteStream);
    return Asset.createFromBytes(byteStream.toByteArray());
}

然后

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.image);
Asset asset = createAssetFromBitmap(bitmap);
PutDataRequest request = PutDataRequest.create("/image");
request.putAsset("profileImage", asset);
Wearable.DataApi.putDataItem(mGoogleApiClient, request);

我发布了我的mainActivity文件。我不确定如何在我的项目中实现您的代码片段。谢谢您的帮助!! - Hello-World
