Android Footstep---Use framelayout to achieve neon effects

Rotate the background color of the 7 TextView in the frame layout, and the color gradient above will change continuously.

First layout in the Main.xml file

The overall layout for the framelayout in the middle of the 7 TextView, representing 7 different colors, you can see the same height, the width is gradually reduced, the newly added textview will not be completely obscured, set the color gradient

<framelayout xmlns:android= "http://schemas.android.com/apk/res/android" android:orientation= "vertical" Androi      D:layout_width= "Fill_parent" android:layout_height= "Fill_parent" > <!--define 7 TextView in turn, the first defined TextView is on the bottom Post-defined TextView located on top---<textview android:id= "@+id/view01" android:layout_width= "Wrap_content" android:l ayout_height= "Wrap_content" android:width= "210px" android:height= "50px" android:background= "#ff0000"/ > <textview android:id= "@+id/view02" android:layout_width= "wrap_content" android:layout_height= "Wrap_cont Ent "android:width=" 180px "android:height=" 50px "android:background=" #dd0000 "/> <textview Android:id= "@+id/view03" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" android:w Idth= "150px" android:height= "50px" android:background= "#bb0000"/> <textview android:id= "@+id/vi Ew04 "Android:layouT_width= "Wrap_content" android:layout_height= "wrap_content" android:width= "120px" android:height= "50px" android:background= "#990000"/> <textview android:id= "@+id/view05" android:layout_width= "Wrap_conte NT "android:layout_height=" Wrap_content "android:width=" 90px "android:height=" 50px "Android:background = "#770000"/> <textview android:id= "@+id/view06" android:layout_width= "Wrap_content" Android:lay          out_height= "Wrap_content" android:width= "60px" android:height= "50px" android:background= "#550000" /> <textview android:id= "@+id/view07" android:layout_width= "wrap_content" android:layout_height= "Wrap_con Tent "android:width=" 30px "android:height=" 50px "android:background=" #330000 "/> </f  Ramelayout>

Use handler to handle updates to the TextView background color, define a thread to perform a task 0.1 seconds at a time, change the value of the CurrentColor variable only, and then send a message to handler notifying it to update the background color of 7 TextView.

Problem: Colors array the place in the EC was prompted by the color cannot be resolved or was not a field???

Colors array the place in the EC is prompted by the color cannot be resolved or isn't a field???
Because: you lack of color resource files, add the following <color.../> sub-elements in String.xml!!!

String.xml

<?xml version= "1.0" encoding= "Utf-8"?><resources>    <string name= "App_name" >framlayout</ string>    <string name= "action_settings" >Settings</string>    <string name= "Hello_world" >hello world!</string>    <color name= "Color1" > #0f0 </color>      <color name= "Color2" > #00f </color>      <color name= "Color3" > #0ff </color>       <color name= "Color4" > #f0f </ color>      <color name= "Color5" > #ff0 </color>       <color name= "Color6" > #07f </color>       <color name= "Color7" > #70f </color></resources>
