Android: Textview does not display setpoint programmatically

Question

I want to set the textview value programmatically, everything seems fine to me, but I don’t know why the set value does not appear

This is the code:

//set the value of a text view
            final TextView textView = (TextView) findViewById(R.id.validityValue);
            textView.setText("30 days");

This is what I have in my xml file

<TextView 
        android:id="@+id/validityValue"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:textSize="12sp"
        android:textColor="#000" />

With the above code, the text view is not displayed when the application starts.
