在网格布局编程设置layout_column和layout_row [英] Set layout_column and layout_row in GridLayout programmatically

问题描述

我有一个网格布局（不GridView控件），我想补充一些意见具有特殊的行和列INEX。在XML中我可以设置观与

 ＆LT;的TextView
    机器人：ID =@ + ID / textView1
    机器人：layout_column =2
    机器人：layout_row =4
    机器人：文本=大文本/＆GT;
 

但我怎么能 layout_column 和 layout_row 编程设置的属性？我想是这样的：

 网​​格布局网格=新的网格布局（getActivity（））;

grid.setColumn（2）;
grid.setRow（4）;

grid.addView（新按钮（getActivity（））;
 

解决方案

layout_column 的等效和 layout_row ，与所有布局_... 参数，是可以找到的的LayoutParams 的子类的参数。

在这种情况下，它的 GridLayout.LayoutParams ，我们用它像这样（为一个2x2的网格，最终的行和列的一个子视图，在细胞内中心）

  gridLayout.setColumnCount（2）;
gridLayout.setRowCount（2）;

gridLayout.addView（子视图，新GridLayout.LayoutParams（
                              GridLayout.spec（1，GridLayout.CENTER），
                              GridLayout.spec（1，GridLayout.CENTER）））;
 

I have a GridLayout (not GridView) where I want to add some views with a special row and column inex. In XML I can set the View with:

<TextView
    android:id="@+id/textView1"
    android:layout_column="2"
    android:layout_row="4"
    android:text="Large Text" />

But how can I set the attributes layout_column and layout_row programmatically? I want something like this:

GridLayout grid = new GridLayout(getActivity());

grid.setColumn(2);
grid.setRow(4);

grid.addView(new Button(getActivity());

解决方案

The equivalent of layout_column and layout_row, as with all layout_... parameters, is to be found as a parameter of a subclass of LayoutParams.

In this case it's GridLayout.LayoutParams, and we use it like this (for a 2x2 grid with a subview in the final row and column, centred within the cell):

gridLayout.setColumnCount(2);
gridLayout.setRowCount(2);

gridLayout.addView(subview, new GridLayout.LayoutParams(
                              GridLayout.spec(1, GridLayout.CENTER),
                              GridLayout.spec(1, GridLayout.CENTER)));
