Question

我试图每1分钟或100米距离获得GPS位置。但onChangeLocation永远不会根据设备上的给定约束来回调。

我在代码中做了什么错误

                            setExpirationTime(1000);

            this.googleApiClient.connect();
    }

    @Override
    public void onConnected(Bundle bundle) {

        isGoogleClientConnected = true;
        if (this.googleApiClient.hasConnectedApi(LocationServices.API)) {
            Toast.makeText(getApplicationContext(), "LocationServices is available.", Toast.LENGTH_LONG).show();

        isGoogleClientConnected = false;
        // try to reconnect is fails in infinite loop
        this.googleApiClient.reconnect();
    }

public void onLocationChanged(Location location) {
        Toast.makeText(getApplicationContext(), "onLocationChanged is called", Toast.LENGTH_LONG).show();

    }

尝试删除setExpirationTime

目前您的请求是

.setFastestInterval(1000).setExpirationTime(1000)

你要求在1000ms通过之前不回电，而不是在1000ms之后回调

LocationServices.FusedLocationApi.requestLocationUpdates onLocationChanged未被回调
