一个Android RadioGroup中的设置选择指数 [英] Set selected index of an Android RadioGroup

问题描述

有没有一种方法来设置一个RadioGroup中的机器人所选择的指标，而不是通过子循环单选按钮并选择检查单选按钮，选择指数？其他

Is there a way to set the selected index of a RadioGroup in android, other than looping through the child radiobuttons and selecting checking the radio button at the selected index?

注：我在运行时填充的单选按钮组

Note: I am populating the Radio Button Group at run time.

推荐答案

如果您的无线组在布局XML文件中定义的，每个按钮可以分配一个ID。然后你只需选中一个按钮，像这样

If your radio group is defined in a layout xml file, each button can be assigned an id. Then you just check a button like this

radioGroup.check(R.id.myButtonId);

如果您以编程方式创建的单选按钮组（我什至不知道你如何做到这一点？），你可能要考虑创建一个特殊的布局xml文件只是为单选组，以便您可以指定R.id *的ID的按钮。

If you created your radio group programmatically (I'm not even sure how you do this...), you might want to consider creating a special layout xml file just for the radio group so that you can assign R.id.* ids to the buttons.
