                 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,<u>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。</u> 
 
       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"。 
 
     <u>  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。</u> 
 
     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 >
