[Android] TableLayout
public class TableLayout extends LinearLayout
查过文档,整理下要点:
- 一个 TableLayout 包含一些 TableRow 对象,每个对象代表一行。除此之外也可以包含其他对象,比如直接放入 <TextView> 。
- TableLayout 容器不会为子元素显示边框线。
- 每一行包含 0 个或多个单元,每个单元可以放一个 View 对象。
- 一个 Table 的单元可以为空
- 单元可以像 HTML 一样占据多列 <span>
- 一个列的宽度由这一列中拥有最宽的单元的某一行宽度决定(想想也是)
- TableLayout 可以用 setColumnShrinkable() 或者 setColumnStretchable() 指定确定的列的收缩性或者扩展性
- 一旦设定可收缩,列的宽度可以被收缩至适应其 parent 对象。
- 一旦设定可拉伸,其可拓展宽度以适应任何多余的空间,但不会超过这个空间
- 表 Table 的总宽度由它自己 parent 的容器决定
- 任一列是可以同时具备可收缩性和可拉伸性的。在这种情况下,列总会改变其尺寸,占满所有的可用空间,且用不会超过这个范围。
- 最后,可以用 setColumnCollapsed() 隐藏一列
我们无法为 TableLayout 的 children 指定 layout_width 属性。宽度永远是 MATCH_PARENT。但 layout_height 属性可以由 child 定义平;默认值是 WRAP_CONTENT。如果一个 child 是 TableRow,则高度总是 WRAP_CONTENT。
表的单元必须按照增加列的排序填至行中,在代码和XML文件都要这样。列的索引是从0开始的。如果你不为 child 单元指定列序号,其会自动向下一个有效列增加。如果你跳过某列的索引,这一列会被视为这一行的空单元。
虽然 TableLayout 典型的 children 是 TableRow,但你也可用任何 View 的子类来作为其直接的 child(第一点)。这个 View 会作为一个占据所有列的单行显示。
看了 APIDemos 的一些例子,感觉比较全面了,这个布局比较简单,也不是很常用,主要是一些规则要熟悉熟悉,下面就直接从 ApiDemos 选一些典型的例子,基本够用了。

1.基本用法:
1 <?xml version="1.0" encoding="utf-8"?> 2 <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" 3 android:layout_width="match_parent" 4 android:layout_height="match_parent"> 5 6 <TableRow> 7 <TextView 8 android:text="@string/table_layout_1_star" 9 android:padding="3dip" /> 10 <TextView 11 android:text="@string/table_layout_1_open" 12 android:padding="3dip" /> 13 <TextView 14 android:text="@string/table_layout_1_open_shortcut" 15 android:padding="3dip" /> 16 </TableRow> 17 18 <TableRow> 19 <TextView 20 android:text="@string/table_layout_1_triple_star" 21 android:padding="3dip" /> 22 <TextView 23 android:text="@string/table_layout_1_save" 24 android:padding="3dip" /> 25 <TextView 26 android:text="@string/table_layout_1_save_shortcut" 27 android:padding="3dip" /> 28 </TableRow> 29 30 <TableRow> 31 <TextView 32 android:text="@string/table_layout_1_star" 33 android:padding="3dip" /> 34 <TextView 35 android:text="@string/table_layout_1_quit" 36 android:padding="3dip" /> 37 <TextView 38 android:text="@string/table_layout_1_quit_shortcut" 39 android:padding="3dip" /> 40 </TableRow> 41 </TableLayout>
效果:
2.有空单元的情况:
1 <TableLayout 2 android:layout_width="match_parent" 3 android:layout_height="match_parent"> 4 5 <TableRow> 6 <Button 7 android:text="@string/table_layout_2_open" /> 8 <TextView 9 android:text="@string/table_layout_2_path_1" 10 android:padding="3dip" /> 11 </TableRow> 12 <TableRow> 13 <Button 14 android:text="@string/table_layout_2_save_all"/> 15 </TableRow> 16 <TableRow> 17 <Button 18 android:text="@string/table_layout_2_save" 19 android:visibility="invisible" /> 20 <TextView 21 android:text="@string/table_layout_2_path_2" 22 android:padding="3dip" /> 23 </TableRow> 24 </TableLayout>
效果
3.加上对齐属性: stretchColumn="1" 拉伸第一列
1 <?xml version="1.0" encoding="utf-8"?> 2 <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" 3 android:layout_width="match_parent" 4 android:layout_height="match_parent" 5 android:stretchColumns="1"> 6 7 <TableRow> 8 <TextView 9 android:text="@string/table_layout_4_open" 10 android:padding="3dip" /> 11 <TextView 12 android:text="@string/table_layout_4_open_shortcut" 13 android:gravity="right" 14 android:padding="3dip" /> 15 </TableRow> 16 17 <TableRow> 18 <TextView 19 android:text="@string/table_layout_4_save" 20 android:padding="3dip" /> 21 <TextView 22 android:text="@string/table_layout_4_save_shortcut" 23 android:gravity="right" 24 android:padding="3dip" /> 25 </TableRow> 26 </TableLayout>
效果:
把stretchColumns="1"改为 stretchColumns="0,1",两列都拉伸
效果:
4.span
1 <TableLayout 2 android:layout_width="match_parent" 3 android:layout_height="wrap_content"> 4 5 <TableRow> 6 <TextView 7 android:text="@string/table_layout_12_a" 8 android:background="#FFFF0000" 9 android:padding="3dip" /> 10 <TextView 11 android:text="@string/table_layout_12_b" 12 android:background="#FF00FF00" 13 android:padding="3dip" /> 14 <TextView 15 android:text="@string/table_layout_12_c" 16 android:background="#FF0000FF" 17 android:padding="3dip" /> 18 </TableRow> 19 20 <TableRow> 21 <TextView 22 android:text="@string/table_layout_12_d" 23 android:layout_span="2" 24 android:gravity="center_horizontal" 25 android:background="#FF0000FF" 26 android:padding="3dip" /> 27 <TextView 28 android:text="@string/table_layout_12_e" 29 android:background="#FF00FF00" 30 android:padding="3dip" /> 31 </TableRow> 32 33 <TableRow> 34 <TextView 35 android:text="@string/table_layout_12_f" 36 android:background="#FFFF00FF" 37 android:padding="3dip" /> 38 <TextView 39 android:text="@string/table_layout_12_g" 40 android:background="#FF00FF00" 41 android:padding="3dip" /> 42 <TextView 43 android:text="@string/table_layout_12_h" 44 android:background="#FFFF0000" 45 android:padding="3dip" /> 46 </TableRow> 47 48 <TableRow> 49 <TextView 50 android:text="@string/table_layout_12_a" 51 android:background="#FF00FF00" 52 android:padding="3dip" /> 53 <TextView 54 android:text="@string/table_layout_12_b" 55 android:layout_span="2" 56 android:gravity="center_horizontal" 57 android:background="#FF0000FF" 58 android:padding="3dip" /> 59 </TableRow> 60 61 <TableRow> 62 <TextView 63 android:text="@string/table_layout_12_g" 64 android:layout_span="3" 65 android:gravity="center_horizontal" 66 android:background="#FFC0C0C0" 67 android:padding="3dip" /> 68 </TableRow> 69 </TableLayout>
效果:
5.复杂布局,garvity 和 layout_gravity 对齐,前者是其 child 的位置,后者是其自身的位置:
1 <TableLayout 2 android:layout_width="match_parent" 3 android:layout_height="wrap_content" 4 android:stretchColumns="1"> 5 6 <TableRow> 7 <TextView 8 android:layout_column="1" 9 android:text="@string/table_layout_7_open" 10 android:padding="3dip" /> 11 <TextView 12 android:text="@string/table_layout_7_open_shortcut" 13 android:gravity="right" 14 android:padding="3dip" /> 15 </TableRow> 16 17 <TableRow> 18 <TextView 19 android:layout_column="1" 20 android:text="@string/table_layout_7_save" 21 android:background="#FF00FF00" 22 android:padding="3dip" /> 23 <TextView 24 android:text="@string/table_layout_7_save_shortcut" 25 android:gravity="right" 26 android:padding="3dip" /> 27 </TableRow> 28 29 <TableRow> 30 <!-- Horizontally centers the content of the cell --> 31 <TextView 32 android:layout_column="1" 33 android:text="@string/table_layout_7_save_as" 34 android:background="#FFFF0000" 35 android:layout_gravity="center_horizontal" 36 android:padding="3dip" /> 37 <TextView 38 android:text="@string/table_layout_7_save_as_shortcut" 39 android:background="#FFFF00FF" 40 android:gravity="right" 41 android:padding="3dip" /> 42 </TableRow> 43 44 <View 45 android:layout_height="2dip" 46 android:background="#FF909090" /> 47 48 <TableRow> 49 <TextView 50 android:text="@string/table_layout_7_x" 51 android:padding="3dip" /> 52 <TextView 53 android:text="@string/table_layout_7_import" 54 android:padding="3dip" /> 55 </TableRow> 56 57 <TableRow> 58 <View 59 android:layout_height="68dip" 60 android:background="#FF909090" /> 61 <!-- Aligns the content of the cell to the bottom right --> 62 <TextView 63 android:text="@string/table_layout_7_export" 64 android:background="#FFFF0000" 65 android:layout_gravity="right|bottom" 66 android:padding="3dip" /> 67 <TextView 68 android:text="@string/table_layout_7_export_shortcut" 69 android:background="#FF00FFFF" 70 android:gravity="right" 71 android:padding="3dip" /> 72 </TableRow> 73 74 <View 75 android:layout_height="2dip" 76 android:background="#FF909090" /> 77 </TableLayout>
效果
