This TableRow layout or its TableLayout parent is possibly useless

I have a warning in an xml file: This TableRow layout or its TableLayout parent is possibly useless.

<TableRow android:id="@+id/tableRow2">
      ...       
</TableRow>

I put the attribute android:id in there, but the warning didn't disappear.

Any ideas as to what may be causing the warning?

The accepted answer is not the best solution, it is terrible practice to ignore warnings. Unless the warning comes from a bug in the compiler or linter itself, eliminating the warning is almost always a better option than ignoring it.

In this case, as the responses to the accepted answer indicate, all you have to do is remove the TableLayout parent of TableRow. The warning is most likely there because you have a table with only one row, so the TableLayout is unnecessary.

E.g. Change this:

<TableLayout 
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TableRow android:id="@+id/tableRow2">
        ...
    </TableRow>
</TableLayout>

To this:

<TableRow
    android:id="@+id/tableRow2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    ...
</TableRow>

Add

tools:ignore="UselessParent"

to your table row to avoid warning or in the tag where you get the warning.
