TableLayout和我们平时在网页上见到的Table有所不同，TableLayout没有边框的，它是由多个TableRow对象组成， 每个TableRow可以有0个或多个单元格，每个单元格就是一个View。这些TableRow，单元格不能设置layout_width,宽度默认是fill_parent的，只有高度layout_height可以自定义，默认是wrap_content。 单元格可以为empty，并且通过android:layout_column可以设置index值实现跳开某些单 元格。在TableRow之间，添加View,设置layout_height以及背景色，就可以实现一条间隔线。 android:layout_span可以设置合并几个单元格 ： <? xml version = "1.0" encoding = "utf-8" ?> < TableLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:layout_width = "fill_parent" android:layout_height = "fill_parent" > < TableRow > < TextView android:text = "column1" android:padding = "3dip" /> < TextView android:text = "column2" android:padding = "3dip" /> < TextView android:text = "column3" android:padding = "3dip" /> </ TableRow > < TableRow > < TextView android:text = "column11" android:visibility ="invisible" /> //cell不见了 < TextView android:text = "左边的invisible" android:gravity = "right" android:padding = "3dip" /> < Button android:id = "@+id/go" android:text = "go" android:padding = "3dip" /> < Button android:text = "cancel" android:padding = "3dip" /> </ TableRow > < View //间隔线 android:layout_height ="2dip" android:background ="#F00" /> < TableRow > < TextView android:text = "右边的cell empty" /> < TextView android:layout_column ="2" android:text = "跳开empty cell" android:padding = "3dip" /> </ TableRow > < TableRow > < TextView android:text = "合并3个单元格" android:layout_span ="3" android:gravity = "center_horizontal" android:background = "#FFC0C0C0" android:textColor = "#f00" android:padding = "3dip" /> </ TableRow > </ TableLayout > 没有设置收缩/伸展效果
注意，原来没有添加 android:padding="3dip" 的，发现那些column会凑在一起的，没有空白间隔！明显看到，那个cancel按钮被挤到几乎看不见了！这时候需要使用 android:shrinkColumns="可收缩的column"，android:stretchColumns="可伸展的column"。 android:shrinkColumns 和android:stretchColumns 的值都是以0开始的index，但必须是string值，即用"1,2,5"来表示。可以用"*"来表示all columns。而且同一column可以同时设置为shrinkable和stretchable。 如果使用TableLayout类的 setColumnShrinkable/setColumnStretchable (int columnIndex, boolean isShrinkable) 就麻烦些了，需要一个一个column来设置。也可以使用TableLayout的 setShrinkAllColumns/setStretchAllColumns 来设置all columns。 判断这些column是否shrinkable或stretchable，可以调用 isColumnShrinkable/isColumnStretchable(int columnIndex)，isShrinkAllColumns()/isStretchAllColumns() 。 <? xml version = "1.0" encoding = "utf-8" ?> < TableLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:layout_width = "fill_parent" android:layout_height = "fill_parent" android:shrinkColumns ="0" > // 设置第一个column可收缩 < TableRow > < TextView android:text = "column1" android:padding = "3dip" /> < TextView android:text = "column2" android:padding = "3dip" /> < TextView android:text = "column3" android:padding = "3dip" /> </ TableRow > < TableRow > < TextView android:text = "column11" android:visibility = "invisible" /> < TextView android:text = "左边的invisible" android:gravity = "right" android:padding = "3dip" /> < Button android:id = "@+id/go2" android:text = "go2" android:padding = "3dip" /> < Button android:text = "cancel" android:padding = "3dip" /> </ TableRow > < View android:layout_height = "2dip" android:background = "#F00" /> < TableRow > < TextView android:text = "右边的cell empty" /> < TextView android:layout_column = "2" android:text = "跳开empty cell" android:padding = "3dip" /> < TextView android:text = "123456789" android:padding = "3dip" /> </ TableRow > </ TableLayout > 可收缩column效果
现在可以看到第一个column为了让第4个column完整显示，而收缩得内容分为几行显示！ 而 可伸展column 的效果就是在其他column可以完整显示时，该column就会伸展，占最多空间： <? xml version = "1.0" encoding = "utf-8" ?> < TableLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:layout_width = "fill_parent" android:layout_height = "fill_parent" android:stretchColumns ="1 " > // 设置第二个column可伸展 < TableRow > < TextView android:text = "column1" android:padding = "3dip" /> < TextView android:text = "column2" android:gravity = "right" android:padding = "3dip" /> < TextView android:text = "column3" android:padding = "3dip" /> </ TableRow > < TableRow > < TextView android:text = "column1" android:padding = "3dip" /> < TextView android:text = "column2" android:gravity = "right" android:padding = "3dip" /> < TextView android:text = "column3" android:padding = "3dip" /> </ TableRow > </ TableLayout > 可伸展column效果
而动态隐藏column，可以调用TableLayout.setColumnCollapsed (int columnIndex, boolean isCollapsed)来指定相应的column。另外TableLayout类的boolean isColumnCollapsed (int columnIndex)能够判断指定的column是否隐藏。 TableLayout可以用来做网页上的Form显示效果，看看官方的sample： <? xml version = "1.0" encoding = "utf-8" ?> < TableLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:layout_width = "fill_parent" android:layout_height = "fill_parent" android:stretchColumns = "1" > < TableRow > < TextView android:text = "@string/table_layout_10_user" android:textStyle = "bold" android:gravity = "right" android:padding = "3dip" /> < EditText android:id = "@+id/username" android:text = "@string/table_layout_10_username_text" android:padding = "3dip" android:scrollHorizontally = "true" /> </ TableRow > < TableRow > < TextView android:text = "@string/table_layout_10_password" android:textStyle = "bold" android:gravity = "right" android:padding = "3dip" /> < EditText android:id = "@+id/password" android:text = "@string/table_layout_10_password_text" android:password = "true" android:padding = "3dip" android:scrollHorizontally = "true" /> </ TableRow > < TableRow android:gravity = "right" > < Button android:id = "@+id/cancel" android:text = "@string/table_layout_10_cancel" /> < Button android:id = "@+id/login" android:text = "@string/table_layout_10_login" /> </ TableRow > </ TableLayout > Form效果
