在Android中制作带有图像的RadioGroup单选按钮...如何? [英] Making RadioGroup radio buttons with images in Android... How?

问题描述

是否可以在Android中制作单选按钮，而不是常规按钮?我希望它看起来像这样:

Is it possible to make Radio Buttons in Android, where there are image representation to a button instead of a regular buttons? I want it to look something like that:

中间的青色表示所选的按钮.

The cyan in the middle represents the selected button.

我该怎么办?

推荐答案

RadioButton 类具有 buttonDrawable 成员，从 CompoundButton 派生.

The RadioButton class has a buttonDrawable member, derived from CompoundButton.

可以通过多种方式更改此可绘制对象.

There are multiple ways you can change this drawable.

来自Java:

myRadioButton.setButtonDrawable(resourceId or Drawable);

来自xml:

<RadioButton
    android:button="@drawable/yourdrawable" 
    ...
/>

如果您只希望选中/未选中状态看起来不同，那么

If you just want the checked/unchecked state look differently, then

• 通过右键单击res文件夹->新建->添加新的选择器xml. Android xml->在上方下拉菜单中选择Drawable->选择 选择器(在日食中)
• 要设置此选择器，请查看以下

• Add a new selector xml by rightclicking your res folder -> New -> Android xml -> select Drawable in the upper dropdown -> choose selector (in eclipse)
• To setup this selector, please take a look at this link
• From now on you can set your freshly created selector to any of your checkboxes/radiobuttons by using its id.
