Android Development-Set the RadioButton click Effect

Using the bottom menu bar in Android development requires the RadioButton component.

In the actual application process, you need to click on the button, in order to let users know whether to click on this button, you can set the click, the button's color or background changes.

The code in this section of layout is:

1 <RadioButton2 android:id="@+id/radio_button0"3 android:layout_height="Fill_parent"4 android:layout_margintop="2.0dip"5 android:drawabletop="@drawable/icon"6 android:tag="Radio_button0"7 android:textcolor="@color/color_radiobutton"
 　　　　　　　　　　　 android:background= "@color/radio_group_selector"8 Android:Checked="True"//set to checked, the displayed effect is the selected font color9 android:text="Button No. 1th"/>Ten <RadioButtonAndroid:id="@+id/radio_button1"android:layout_height="Fill_parent"android:layout_margintop= "2.0dip" 14 android:tag= "radio_button1  "15 android:drawabletop=  " @drawable/icon" 
  android:background= "@color/radio_group_sele ctor " 16 android:textcolor="  @color/color_radiobutton "17 Android:text= " button 2nd # "/>      

You can see android:textcolor="@color/color_radiobutton" in RadioButton

android:background="@color/radio_group_selector"

This is going to correspond to two files.

Under the Res folder, create a name called Color folder, and then create an XML file in the Color folder Color_radiobutton to set the selected click Color change for changing the font

That is, the file directory is: Res/color/color_radiobutton

The code for this file is

1<?xml version="1.0"encoding="Utf-8"?>2<selector xmlns:android="http://schemas.android.com/apk/res/android">3   4   5<item android:state_checked="true"Android:color="@color/green"/>6<!--not selected--7<itemandroid:state_checked="false" Android:color="@color/white"/>8   9   Ten</selector>

Under the Res folder, create a name called Color folder, and then create an XML file in the Color folder Radio_group_selector to set the selected click Color change for changing the font

That is, the file directory is: Res/color/radio_group_selector

1<?xml version="1.0"encoding="Utf-8"?>2<selector xmlns:android="http://schemas.android.com/apk/res/android">3<item android:state_checked="true"android:drawable="@color/green"></item>4<item android:state_checked="false"android:drawable="@color/black"></item>5</selector>

You can see that when the color of the click Is green, the color is green without being clicked, the text is white and the background is black.

And, of course, set the color in Res/values/color.xml.

1<?xml version="1.0"encoding="Utf-8"?>2<resources>3<color name="Black">#000000</color>4<color name=" White"> #FFFFFF </color>5<color name="Green"> #00FF00 </color>6     7</resources>

It's done.
