Android 文本视图文本已更改但未显示

我有一个文本视图，当我使用

tv.setText（“hello”）更改文本时它更改了文本，因为我使用
'Log.d（TAG，tv.getText（））；”进行检查但当我运行应用程序时，更改不会显示在视觉上。有什么问题吗

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（相当复杂）：


请张贴您的完整代码。我认为问题在于别的。您上面发布的代码是正确的。但是在那之后，实现了哪些代码？我认为代码会影响xml

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

请在您使用的地方共享代码，但当我运行应用程序时，更改不会显示在视觉上。请共享您的xml和代码。请检查文本的颜色代码，可能是它的白色，其中是
tv.setText
？humidityC.setText（“+liveDataCat[1]）；检查liveDataCat[1]包含什么？检查textcolor alsoHappy以帮助您@tirsrami如果出现任何其他问题将帮助您：）：）：）哈哈哈，但好的方面是它现在可以工作了。所以享受@tirsrami吧
