您需要在实例化 GoogleApiClient.Builder 时再添加一个范围：
".addScope(new Scope(Scopes.FITNESS_LOCATION_READ))"
您还需要通过在清单文件中添加此权限来获得位置权限：
<manifet>
...
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<aplication/>
</manifest>
并在您的活动中，添加此方法：
public void request_location_permission() {
// If location permission was not granted yet, request it. Otherwise, request nothing and
// just do what you want.
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) !=
PackageManager.PERMISSION_GRANTED) {
PermissionUtils.requestPermission(this, LOCATION_PERMISSION_REQUEST_CODE,
Manifest.permission.ACCESS_FINE_LOCATION, false);
} else {
process();
}
}
PermissionUtils 是我自己的类，如果你想先看结果，可以用它来提示一下：
public abstract class PermissionUtils {
/**
* Requests the fine location permission. If a rationale with an additional explanation should
* be shown to the user, displays a dialog that triggers the request.
*/
public static void requestPermission(AppCompatActivity activity, int requestId,
String permission, boolean finishActivity) {
if (ActivityCompat.shouldShowRequestPermissionRationale(activity, permission)) {
// Display a dialog with rationale, this dialog wil request permission by itself.
PermissionUtils.RationaleDialog.newInstance(requestId, finishActivity)
.show(activity.getSupportFragmentManager(), "dialog");
} else {
// Location permission has not been granted yet, request it.
ActivityCompat.requestPermissions(activity, new String[]{permission}, requestId);
}
}
/**
* Checks if the result contains a {@link PackageManager#PERMISSION_GRANTED} result for a
* permission from a runtime permissions request.
*
* @see android.support.v4.app.ActivityCompat.OnRequestPermissionsResultCallback
*/
public static boolean isPermissionGranted(String[] grantPermissions, int[] grantResults,
String permission) {
for (int i = 0; i < grantPermissions.length; i++) {
if (permission.equals(grantPermissions[i])) {
return grantResults[i] == PackageManager.PERMISSION_GRANTED;
}
}
return false;
}
/**

public static class PermissionDeniedDialog extends DialogFragment {
private static final String ARGUMENT_FINISH_ACTIVITY = "finish";
private boolean mFinishActivity = false;
/**

public static PermissionDeniedDialog newInstance(boolean finishActivity) {
Bundle arguments = new Bundle();
arguments.putBoolean(ARGUMENT_FINISH_ACTIVITY, finishActivity);
PermissionDeniedDialog dialog = new PermissionDeniedDialog();

public static RationaleDialog newInstance(int requestCode, boolean finishActivity) {

这是我通过创建自己的 Rational 对话框获得用户授予位置权限的方式，您可以通过在 google 上搜索如何获得位置权限来以不同的方式进行。
希望这会有所帮助，
时间。
