当我从布局中删除 Horizo​​ntalScrollView 时出现此错误

Answer 1

我认为这是您的第二个表格布局，其中没有任何列，但您正试图将它们全部拉伸(stretch)。

<TableLayout android:layout_width="wrap_content"
                android:layout_height="wrap_content" android:stretchColumns="*"
                android:scrollbars="vertical"
                android:scrollbarAlwaysDrawVerticalTrack="true" android:id="@+id/pinDetailsTable">
                <TableRow>
                    <!-- <TextView android:text="" android:padding="3dip" style="@style/text_subheader_wh" 
                        /> <TextView android:text="" android:padding="3dip" style="@style/text_subheader_wh" 
                        /> <TextView android:text="" android:padding="3dip" style="@style/text_subheader_wh" 
                        /> <TextView android:text="" android:padding="3dip" style="@style/text_subheader_wh" 
                        /> <TextView android:text="" android:padding="3dip" style="@style/text_subheader_wh" 
                        /> -->
                </TableRow>
            </TableLayout>
