Java 在我使用updateDisplay方法之前，一切都正常，导致应用程序崩溃

所有内容都会正确显示在屏幕上，直到我用代码填写

updateDisplay（）

方法，以使用

setText/get

更新我的

textview

在从DarkSky API输入要更新的

setText/get

代码之前，应用程序不会崩溃，但一旦输入，应用程序就会崩溃并告诉我重试

我相信所有信息都输入正确，但由于某些原因，应用程序不会接收信息。另外，我在摇篮中使用了最新版本的OkHTTP，所以问题不在这里。（还使用了权限）

编辑： 添加了堆栈跟踪的图像

摆脱了我使用的Butterknife格式（BindVIew），选择了这种格式，现在一切正常，正在从API检索更新信息：

公共类MainActivity扩展了AppCompatActivity{

public static final String TAG = MainActivity.class.getSimpleName();

private CurrentWeather mCurrentWeather;

private TextView mTimeLabel;

private TextView mTempLabel;

private TextView mHumidityValue;

private TextView mPrecipValue;

private TextView mSummaryLabel;

private ImageView mIconImageView;



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

    mTimeLabel = (TextView) findViewById(R.id.timeLabel);
    mTempLabel = (TextView) findViewById(R.id.tempLabel);
    mHumidityValue = (TextView) findViewById(R.id.humidityValue);
    mPrecipValue = (TextView) findViewById(R.id.precipValue);
    mSummaryLabel = (TextView) findViewById(R.id.summaryLabel);

发布崩溃中的堆栈跟踪。另外，继续并检查该方法中没有任何内容是空的。这可能是我们目前显示的问题。我已经添加了堆栈跟踪的屏幕截图。我不认为它是空的？我不太确定堆栈跟踪是否非常清楚-您正在尝试引用空对象-可能是使用settex我对应用程序开发非常陌生，所以我不确定我应该从那里做什么，因为它是空的？

public static final String TAG = MainActivity.class.getSimpleName();

private CurrentWeather mCurrentWeather;
