Android开发中TableLayout表格布局

Android开发中TableLayout表格布局 一、引言 在移动端应用程序开发中,常常会使用到表格布局,iOS和Android开发框架中都提供了独立的表格视图控件供开发者使用,例如iOS中的UITableView、UICollectionView,Android中的ListView、GridView等。除了独立的视图控件外,Android中还提供了一个布局容器类TableLayout,使用其也可以进行方便的表格布局。 前边博客有介绍过关于LinearLayout线性布局的相关内容,LinearLayout只能进行水平或者垂直方向上的排列布局,使用LinearLayout的布局嵌套,实际上也可以实现表格布局的样式。实际上,TableLayout就是采用这样的原理,TableLayout继承于LinearLayout,其中每个视图元素作为一行,同时Android中还提供了一个TableRow类,这个类同样继承自LinearLayout,其中每个视图元素作为当前行中的一列,结合使用TableLayout与TableRow,就实现了行列的表格布局。 二、关于TableRow TableRow可以简单理解为TableLayout布局中的一行,当然,TableLayout中也可以直接添加任意的View视图,但是默认添加的View视图将独占一行。TableRow中可以添加其他视图

Android table layout formatting problems

一笑奈何 提交于 2019-11-30 11:23:03
问题 I can not get my TableLayout to fit inside the screen when the text cell is large , despite the text wraps inside the cell . This is my TableLayout. A simple two-rows, two-columns table. Left column cells are multiline . If the text of one of these cell is large enought to break in two lines, the column is stretched to fill the entire screen and the right columns is pushed out of the screen. Why? How can I force the full table to stay inside the screen? Any hint is welcomed. My TableLayout is

Scroll to last line of TableLayout within a ScrollView

大憨熊 提交于 2019-11-29 17:44:56
问题 I want to have a dynamic table, with rows added over time as a result of user interaction, using a TableLayout inside a ScrollView. This works fine, but when I want to scroll to the end of the table using fullScroll(), it always leaves out the last line; that is, it scrolls so that the one before the last one is visible. The last line is visible when scrolling manually, and the scrollbar is correct too. I'm of course open to suggestions as to how to make a better layout out of this; but I'm

Android: mass enable/disable buttons

孤人 提交于 2019-11-29 14:20:53
I have an activity where a bunch of buttons are placed inside TableLayout, not unlike a dial pad. During some operations I need to temporarily disable the buttons. To my unpleasant surprise doing TableLayout.setEnabled(false) has no effect on the nested buttons. Am I stuck with setting each individual button or is there a nifty (better) way to achieve the same? I'd try to do something like this: TableLayout tableLayoutInstance; // let's suppouse you have already initialized it // blablabla // example to deactivate all buttons ArrayList<View> touchables = tableLayoutInstance.getTouchables();

一、Tablelayout简介 Tablelayout类以行和列的形式对控件进行管理,每一行为一个TableRow对象,或一个View控件。 当为TableRow对象时,可在TableRow下添加子控件,默认情况下,每个子控件占据一列。 当为View时,该View将独占一行。 二、TableLayout行列数的确定 TableLayout的行数由开发人员直接指定,即有多少个TableRow对象(或View控件),就有多少行。 TableLayout的列数等于含有最多子控件的TableRow的列数。如第一TableRow含2个子控件,第二个TableRow含3个,第三个TableRow含4个,那么该TableLayout的列数为4. 三、TableLayout可设置的属性详解 TableLayout可设置的属性包括全局属性及单元格属性。 1、全局属性也即列属性,有以下3个参数: android:stretchColumns 设置可伸展的列。该列可以向行方向伸展,最多可占据一整行。 android:shrinkColumns 设置可收缩的列。当该列子控件的内容太多,已经挤满所在行,那么该子控件的内容将往列方向显示。 android:collapseColumns 设置要隐藏的列。 示例: android:stretchColumns="0" 第0列可伸展 android

Variable sized column with ellipsis in a table

我的未来我决定 提交于 2019-11-29 11:31:58
I am trying to layout a table in CSS. The requirements are as follow: the first column expands as much as it can, and text in the first column is limited to one line of text, if more, there should be an ellipsis. The other columns take only the space they need to contain the text in them without wrapping (text-wrap: nowrap). The table itself is 100% width. I managed to have either a fixed size first column with ellipsis, or a variable size first column with no ellipsis, I can't find a way to have a variable sized columns with ellipsis. Is it achievable with CSS? I can use CSS 3 properties if

I'm currently creating a side-scroller style game for my final year project for my degree. I'm just wondering how you make the menu designed for when the phone is in horizontal orientation display, even when the phone is held in it's vertical orientation? i.e. I want the user to know that the game has to be played with the phone in it's horizontal orientation and want the menu's to only display in the horizontal orientation. Many thanks in advance. Add the following attribute to your activity in your AndroidManifest.xml: android:screenOrientation="landscape" Well, I didn't get your question
