Текст TextView изменен, но не отображается

Question

У меня есть текстовое представление, и когда я меняю текст, используя tv.setText("hello");, он меняет текст, потому что я проверяю 'Log.d(TAG, tv.getText());', но когда я запускаю приложение, изменения не отображаются визуально. В чем проблема?

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    getBundleData(); 
    setContentView(R.layout.activity_device_sensor_report); 

    context = this; 


    tempN = (TextView) findViewById(R.id.tv_temperature_num); 
    tempC = (TextView) findViewById(R.id.tv_temperature_cat); 
    humidityC = (TextView) findViewById(R.id.tv_humidity_cat); 


    tempN.setText("" + liveDataNum[0]); 
    humidityC.setText("" + liveDataCat[1]); 
    Log.d("TAG", ""+humidityC.getText()); 

    drawGraph(); 

} 

XML (его довольно сложный):

Edit: я чист/восстановить и это то, что случилось:

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class 
Error:(org.eclipse.paho.client.mqttv3.persist.MqttDefaultFilePersistence$1) that doesn't come with an 
Error:associated EnclosingMethod attribute. This class was probably produced by a 
Error:compiler that did not target the modern .class file format. The recommended 
Error:solution is to recompile the class from source, using an up-to-date compiler 
Error:and without specifying any "-target" type options. The consequence of ignoring 
Error:this warning is that reflective operations on this class will incorrectly

Пожалуйста, разместите свой полный код. Я думаю, что проблема в другом. ваш выше опубликованный код верен. Но после этого какой код реализован? Я думаю, что код влияет на XML

TextView humidityC = (TextView) findViewById(R.id.tv_humidity_cat); 
     humidityC.setText("Humidity"); 
     Log.d("TAG", ""+humidityC.getText());
