Android 获取每日步数

要获取 Android 设备的每日步数，可以使用 Google Fit API。以下是获取步数的简单示例代码：

1. 在 build.gradle 文件中添加以下依赖项：

dependencies {
    implementation 'com.google.android.gms:play-services-fitness:20.0.0'
}

2. 在 AndroidManifest.xml 文件中添加以下权限：

<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION"/>

3. 在 MainActivity.java 文件中添加以下代码：

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.ResultCallback;
import com.google.android.gms.common.api.Status;
import com.google.android.gms.fitness.Fitness;
import com.google.android.gms.fitness.data.DataSet;
import com.google.android.gms.fitness.request.DataReadRequest;
import com.google.android.gms.fitness.result.DataReadResult;

import java.text.DateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.concurrent.TimeUnit;

public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener {

    private GoogleApiClient mClient = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Create a GoogleApiClient instance
        mClient = new GoogleApiClient.Builder(this)
                .addApi(Fitness.HISTORY_API)
                .addScope(Fitness.SCOPE_ACTIVITY_READ)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

        // Connect to the Google Fit API
        mClient.connect();
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) {
        // Get the current date
        Calendar cal = Calendar.getInstance();
        Date now = new Date();
        cal.setTime(now);
        long endTime = cal.getTimeInMillis();
        cal.set(Calendar.HOUR_OF_DAY, 0);
        cal.set(Calendar.MINUTE, 0);
        cal.set(Calendar.SECOND, 0);
        cal.set(Calendar.MILLISECOND, 0);
        long startTime = cal.getTimeInMillis();

        // Create a data request for the step count
        DataReadRequest readRequest = new DataReadRequest.Builder()
                .aggregate(Fitness.HISTORY_API, Fitness.HistoryApi.AggregateRequest.STEP_COUNT_DELTA)
                .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
                .build();

        // Retrieve the step count
        Fitness.HistoryApi.readData(mClient, readRequest).setResultCallback(new ResultCallback<DataReadResult>() {
            @Override
            public void onResult(DataReadResult dataReadResult) {
                DataSet dataSet = dataReadResult.getDataSet(Fitness.HistoryApi.AggregateRequest.STEP_COUNT_DELTA);
                int totalSteps = 0;
                for (com.google.android.gms.fitness.data.DataPoint dp : dataSet.getDataPoints()) {
                    for (com.google.android.gms.fitness.data.Field field : dp.getDataType().getFields()) {
                        int steps = dp.getValue(field).asInt();
                        totalSteps += steps;
                    }
                }
                Log.i("Step Count", "Total steps: " + totalSteps);
            }
        });
    }

    @Override
    public void onConnectionSuspended(int i) {
        Log.i("Google Fit", "Connection suspended");
    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
        Log.i("Google Fit", "Connection failed");
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        mClient.disconnect();
    }
}

这将获取当前日期的步数，并将其打印到 Logcat 中。您可以根据需要更改日期范围。注意，此代码需要用户授权才能访问步数数据，因此您需要在运行时请求相应的权限。
