Android 更换RadioButton图标和监听事件

Android 更换RadioButton图标只需定义一个selector文件，然后在布局中引用即可。

在drawable中建立myradiobutton.xml文档并导入图片：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/item_radio_check" android:state_checked="true"         
          android:state_enabled="false" android:state_pressed="false"></item> 
    <item android:drawable="@drawable/item_radio_check" android:state_checked="true" 
          android:state_enabled="true" android:state_pressed="false"></item>
    <item android:drawable="@drawable/item_radio_uncheck" android:state_checked="false" 
          android:state_enabled="false" android:state_pressed="false"></item>
    <item android:drawable="@drawable/item_radio_uncheck" android:state_checked="false" 
          android:state_enabled="true" android:state_pressed="false"></item>
</selector>

然后在布局文件中引用即可：

<RadioButton
   android:id="@+id/rb2"
   android:layout_width="0dp"
   android:layout_height="wrap_content"
   android:layout_weight="1"
   android:button="@drawable/myradiobutton"
   android:text="  男" />

监听事件

RadioButton为单选按钮，他需要与RadioGroup配合使用

group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                switch (checkedId) {
                    case R.id.rb1:
                        
                        break;
                    case R.id.rb2:
                        
                        break;
                    default:
                        break;
                }
            }
        });
