我的方法

请参阅MainActivity，我创建新活动实现NestAPI.AuthenticationListener，Listener.ThermostatListener
从MainActivity复制implements方法的内容和验证方法

运行后，身份验证成功，因为消息＆＃34;身份验证成功。＆＃34;在logcat中。但是，恒温器对象mThermostat仍为空，无法获取信息。

P.S。如果复制MainActivity的mthermostat设备ID，我可以修改目标温度。

有谁知道如何初始恒温器对象？

当我尝试编写一个简单的示例来上传时，我解决了这个问题：我

我发现我必须添加fetchData()来设置恒温器的监听器，然后mthermostat可以是初始的并在onThermostatUpdated(@NonNull Thermostat thermostat)中更新。

import android.app.Activity;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.util.Log;
import android.view.View;
import android.widget.TextView;

import com.nestapi.codelab.demo.R;
import com.nestapi.codelab.demo.Settings;
import com.nestapi.lib.API.*;

public class Activity4Test extends Activity implements
    NestAPI.AuthenticationListener, Listener.ThermostatListener {

    private Listener mUpdateListener;
    private NestAPI mNestApi;
    private Thermostat mThermostat;
    private AccessToken mToken;

    TextView txvGet;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_4test);
        mNestApi = NestAPI.getInstance();//Initial NestAPI, connect Firebase
        mToken = Settings.loadAuthToken(this);//Loade AccessToken
        authenticate(mToken);

        txvGet = (TextView) findViewById(R.id.txvGet);
    }

    private void authenticate(AccessToken token) {
        Log.v("Activity4Test", "Authenticating...");
        NestAPI.getInstance().authenticate(token, this);
    }

    @Override
    public void onAuthenticationSuccess() {
        Log.v("Activity4Test", "Authentication succeeded.");
        fetchData();
    }

    @Override
    public void onAuthenticationFailure(int errorCode) {
        Log.v("Activity4Test", "Authentication failed with error: " + errorCode);
    }

    private void fetchData() {
        Log.v("Activity4Test", "Fetching data...");

        mUpdateListener = new Listener.Builder()
                .setThermostatListener(this)
                .build();
        mNestApi.addUpdateListener(mUpdateListener);
    }

    @Override
    public void onThermostatUpdated(@NonNull Thermostat thermostat) {
        Log.v("Activity4Test", String.format("Thermostat (%s) updated.", thermostat.getDeviceID()));
        mThermostat = thermostat;
    }

Android-NestDK无法初始恒温对象
