android - Change color of button -


How do I change the color of a button using XML files? I tried to use android: background = "@ android: color / black" but it works only for black and white as much as I can tell. Can someone explain this to me. Why not android: background = "@ android: color / blue" ?

You can do this with a selector file like this: 

  & lt; item android: state_pressed = "true" & gt; & Lt; Size & gt; & Lt; Shield Android: startColor = "@ android: Color / Yellow" Android: endColor = "@ Android: Color / Yellow" Android: Angle = "270" /> & Lt; Stroke Android: width = "3dp" Android: Color = "@Android: Color / Gray" /> & Lt; Corners Android: Radius = "3dp" /> & Lt; padding android: left = "10dp" Android: top = "10dp" Android: right = "10dp" Android: bottom = "10dp" /> & Lt; / Size & gt; & Lt; / Item & gt; & Lt; Android Android: state_focused = "true" & gt; & Lt; Size & gt; & Lt; Shield Android: endColor = "@ android: color / orange" Android: startColor = "@Android: Color / Orange" Android: Angle = "270" /> & Lt; Stroke Android: width = "3dp" Android: Color = "@Android: Color / Gray" /> & Lt; Corners Android: Radius = "3dp" /> & Lt; padding android: left = "10dp" Android: top = "10dp" Android: right = "10dp" Android: bottom = "10dp" /> & Lt; / Size & gt; & Lt; / Item & gt; & Lt; Items & gt; & Lt; Size & gt; & Lt; Shield Android: endColor = "@ android: color / blue" Android: startColor = "@ Android: Color / Blue" Android: Angle = "270" /> & Lt; Stroke Android: width = "3dp" Android: Color = "@Android: Color / Gray" /> & Lt; Corner Android: Radius = "3dp" /> & Lt; padding android: left = "10dp" Android: top = "10dp" Android: right = "10dp" Android: bottom = "10dp" /> & Lt; / Size & gt; & Lt; / Item & gt; For example, name the file custom_button.xml, then in the actual button:  
  background = "@ drawable /   referenced from custom_button "

c# - ASP.NET MVC - Attaching an entity of type 'MODELNAME' failed because another entity of the same type already has the same primary key value -

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.
