Android - TextViews not showing up in ListView

Question

I'm having an issue to where none of my TextViews are showing up in the ListView. I'm not sure whether it is an issue with the layout or the java class itself. There are two images here, one of the application running after data had been entered into the database and one of what it is supposed to look like.

Layout for each row of data in ListView

Fragment for the ListView (Delete Button appears but not the TextViews)

row_layout.xml

I don't believe the issue is with database showing the data because some of the TextViews in the ListView don't even use the data from inside the database.

Answer 1

set your adapter upon listview in the last..............

Answer 2

your row_layout.xml file textview in set textcolor:

 <TextView
    android:layout_width="123dp"
    android:layout_height="wrap_content"
    android:id="@+id/resultTeamNumber"
    android:text="Here Number"
    android:textSize="18dp"
    android:layout_alignParentTop="true"
    android:layout_alignParentStart="true" 
    android:textColor="@android:color/black"

/>

Answer 3

It is theme issue on your end,probably textcolor set to white in your theme change these

<item name="android:textColorPrimary">@color/white</item>
<item name="android:textColorSecondary">@color/white</item>

change it to black
