如何在Google Fit History API中显示每天的步伐？

Question

我正在尝试为我的应用提供Google健身历史记录api，我想在手机屏幕上显示日常操作，但我不知道该怎么做。如果能对此有所帮助，并在可能的情况下分别显示每天的数据，那将更好。目前，如您所见，我正在获取日志。

这是我的代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    textView=  (TextView) findViewById(R.id.hello);
    mButtonViewWeek = (Button) findViewById(R.id.btn_view_week);
    mButtonViewToday = (Button) findViewById(R.id.btn_view_today);
    mButtonAddSteps = (Button) findViewById(R.id.btn_add_steps);
    mButtonUpdateSteps = (Button) findViewById(R.id.btn_update_steps);
    mButtonDeleteSteps = (Button) findViewById(R.id.btn_delete_steps);

    mButtonViewWeek.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new ViewWeekStepCountTask().execute();
        }
    });
    mButtonViewToday.setOnClickListener(this);
    mButtonAddSteps.setOnClickListener(this);
    mButtonUpdateSteps.setOnClickListener(this);
    mButtonDeleteSteps.setOnClickListener(this);

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Fitness.HISTORY_API)
            .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
            .addConnectionCallbacks(this)
            .enableAutoManage(this, 0, this)
            .build();

}

private class ViewWeekStepCountTask extends AsyncTask<Void, Void, Void> {
    protected Void doInBackground(Void... params) {
        displayLastWeeksData();
        return null;
    }
}

检索数据：

    public void displayLastWeeksData(){

        Date date1 = new Date();
        SimpleDateFormat  formatter1 = new SimpleDateFormat("MMddyyyy");
        String format = formatter1.format(date1);

        SimpleDateFormat  formatter = new SimpleDateFormat("MMddyyyy hh:mm:ss", Locale.ENGLISH);
        Calendar cal = Calendar.getInstance();

        Date today = null;
        try {
            today = formatter.parse(format+" 00:00:00");
        } catch (ParseException e) {
            e.printStackTrace();
        }
        cal.setTime(today);
        cal.add(Calendar.MONTH, -1);
        long start = cal.getTimeInMillis();
        System.out.println("start time:"+start);

        Date date= null;
        try {
            date = formatter.parse(format+" 23:59:59");
        } catch (ParseException e) {
            e.printStackTrace();
        }
        cal.setTime(date);
        long end = cal.getTimeInMillis();
        System.out.println("end time: "+end);

        Date tem= new Date();

        cal.setTime(tem);

        long present = cal.getTimeInMillis();

        System.out.println(present);


        cal.setTime(today);




        java.text.DateFormat dateFormat = DateFormat.getDateInstance();
        Log.e("History", "Range Start: " + dateFormat.format(start));
        Log.e("History", "Range End: " + dateFormat.format(end));

//Check how many steps were walked and recorded in the last 7 days
        final DataReadRequest readRequest = new DataReadRequest.Builder()
                .aggregate(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
                .bucketByTime(1, TimeUnit.DAYS)
                .setTimeRange(start, end, TimeUnit.MILLISECONDS)
                .build();

        final DataReadResult dataReadResult = Fitness.HistoryApi.readData(mGoogleApiClient, readRequest).await(1,TimeUnit.MINUTES);
//Used for aggregated data
        if (dataReadResult.getBuckets().size() > 0) {
            Log.e("History", "Number of buckets: " + dataReadResult.getBuckets().size());
            for (Bucket bucket : dataReadResult.getBuckets()) {
                List<DataSet> dataSets = bucket.getDataSets();
                for (DataSet dataSet : dataSets) {
                    showDataSet(dataSet);
                }
            }
        }
//Used for non-aggregated data
        else if (dataReadResult.getDataSets().size() > 0) {
            Log.e("History", "Number of returned DataSets: " + dataReadResult.getDataSets().size());
            for (DataSet dataSet : dataReadResult.getDataSets()) {
                showDataSet(dataSet);
            }
        }

    }

用于显示值：

private void showDataSet(DataSet dataSet) {
    Log.e("History", "Data returned for Data type: " + dataSet.getDataType().getName());
    DateFormat dateFormat = DateFormat.getDateInstance();
    DateFormat timeFormat = DateFormat.getTimeInstance();

    for (DataPoint dp : dataSet.getDataPoints()) {

        Log.e("History", "Data point:");
        Log.e("History", "\tType: " + dp.getDataType().getName());
        Log.e("History", "\tStart: " + dateFormat.format(dp.getStartTime(TimeUnit.MILLISECONDS)) + " " + timeFormat.format(dp.getStartTime(TimeUnit.MILLISECONDS)));
        Log.e("History", "\tEnd: " + dateFormat.format(dp.getEndTime(TimeUnit.MILLISECONDS)) + " " + timeFormat.format(dp.getStartTime(TimeUnit.MILLISECONDS)));
        for (Field field : dp.getDataType().getFields()) {
            Log.e("History", "\tField: " + field.getName() +
                    " Value: " + dp.getValue(field));

            //textView.setText(dp.getValue(field).toString());

        }
    }
}

    @Override
    public void onConnectionSuspended(int i) {
        Log.e("HistoryAPI", "onConnectionSuspended");
    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
        Log.e("HistoryAPI", "onConnectionFailed");
    }
@Override
    public void onConnected(@Nullable Bundle bundle) {
        Log.e("HistoryAPI", "onConnected");
new ViewWeekStepCountTask().execute();
    }


    @Override
    public void onClick(View v) {
    }
}
