如何在Android中将图像作为单选按钮

问题描述

在我的应用中，我想从用户那里获得调查答案。所以，我已经决定将笑脸图像作为单选按钮。在Android上有可能吗？

In my app, I want to get survey answers from the user. So, I've decided put smiley images to act as a radio buttons. Is it possible on android?

例如，当用户触摸图像时，我将显示笑脸图像，它将像单选按钮一样被激活。一次，他们将被允许只选择一个。如果有人可以指导我，我将不胜感激。

For example, I will show smiley images when user touches the image and it will be activated like a radio button. At a time, they will be allowed to only choose one. If anyone could guide me, I would appreciate it.

提前致谢！

为您的radiobutton提供自定义样式：

Give your radiobutton a custom style:

<style name="MyRadioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
    <item name="android:button">@drawable/custom_btn_radio</item>
</style>

custom_btn_radio.xml

custom_btn_radio.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:state_checked="true" android:state_window_focused="false"
      android:drawable="@drawable/btn_radio_on" />
   <item android:state_checked="false" android:state_window_focused="false"
      android:drawable="@drawable/btn_radio_off" />

   <item android:state_checked="true" android:state_pressed="true"
      android:drawable="@drawable/btn_radio_on_pressed" />
   <item android:state_checked="false" android:state_pressed="true"
      android:drawable="@drawable/btn_radio_off_pressed" />

   <item android:state_checked="true" android:state_focused="true"
      android:drawable="@drawable/btn_radio_on_selected" />
   <item android:state_checked="false" android:state_focused="true"
      android:drawable="@drawable/btn_radio_off_selected" />

   <item android:state_checked="false" android:drawable="@drawable/btn_radio_off" />
