先看效果图:
方法一:
公司理财项目里面用到的,当选中radioButton后要改变背景色和自提颜色,试了好几次这么都不行。
于是想到了selecter背景选择器,可是怎么写都不对。终于找到一种成功的写法了。下面是字体颜色改变的方法
shape_financing_text_color.xml
<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="/apk/res/android"><item android:color="#ffffff" android:state_checked="true" /><item android:color="#000000" android:state_checked="false" /></selector>
下面是整个radiobutton背景颜色改变的方法
<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="/apk/res/android"><item android:state_checked="true"><shape><solid android:color="@color/colorMain" /><stroke android:width="@dimen/dp_1" android:color="@color/colorKeyBoard" /></shape></item><item android:state_checked="false"><shape><stroke android:width="@dimen/dp_1" android:color="@color/colorKeyBoard" /></shape></item></selector>
如何引用呢?
很简单如下:
在textcolor中引用这个选择器就好了
<RadioGroupandroid:id="@+id/rg_financing_home"android:layout_width="match_parent"android:layout_height="@dimen/dp_45"android:orientation="horizontal"><RadioButtonandroid:id="@+id/rb_financing_home"android:layout_width="0dp"android:layout_height="match_parent"android:layout_weight="1"android:background="@drawable/shape_financing_bg"android:button="@null"android:checked="true"android:gravity="center"android:text="首页"android:textColor="@drawable/shape_financing_text_color" /><RadioButtonandroid:id="@+id/rb_financing_money"android:layout_width="0dp"android:layout_height="match_parent"android:layout_marginLeft="0.5dp"android:layout_marginRight="0.5dp"android:layout_weight="1"android:background="@drawable/shape_financing_bg"android:button="@null"android:gravity="center"android:text="资产"android:textColor="@drawable/shape_financing_text_color" /><RadioButtonandroid:id="@+id/rb_financing_mine"android:layout_width="0dp"android:layout_height="match_parent"android:layout_weight="1"android:background="@drawable/shape_financing_bg"android:button="@null"android:gravity="center"android:text="我的"android:textColor="@drawable/shape_financing_text_color" /></RadioGroup>
方法二:
看小效果图:
先创建selecter
放在res/color里面
没有color文件夹需要自己创建color文件夹哈
text_color.xml
<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="/apk/res/android"><item android:color="#66ff66" android:state_checked="true" /><item android:color="#00ffff" android:state_checked="false" /></selector>
然后在xml中引用即可
android:textColor="@color/text_color"
<RadioGroupandroid:id="@+id/rg_financing_home"android:layout_width="match_parent"android:layout_height="@dimen/dp_45"android:orientation="horizontal"><RadioButtonandroid:id="@+id/rb_financing_home"android:layout_width="0dp"android:layout_height="match_parent"android:layout_weight="1"android:background="@drawable/shape_financing_bg"android:button="@null"android:checked="true"android:gravity="center"android:text="首页"android:textColor="@color/text_color" /><RadioButtonandroid:id="@+id/rb_financing_money"android:layout_width="0dp"android:layout_height="match_parent"android:layout_marginLeft="0.5dp"android:layout_marginRight="0.5dp"android:layout_weight="1"android:background="@drawable/shape_financing_bg"android:button="@null"android:gravity="center"android:text="资产"android:textColor="@color/text_color" /><RadioButtonandroid:id="@+id/rb_financing_mine"android:layout_width="0dp"android:layout_height="match_parent"android:layout_weight="1"android:background="@drawable/shape_financing_bg"android:button="@null"android:gravity="center"android:text="我的"android:textColor="@color/text_color" /></RadioGroup>
