I was trying to access the record Id in custom lightning component in Salesforce Community (Napili Template) Case Record Detail page
We have done some research and found some solutions:

http://salesforce.stackexchange.com/questions/93060/lightning-component-record-id-when-component-in-lightning-page?lq=1
 
I tried every single one, none of them works.
Code I tried:
<aura:component implements="forceCommunity:availableForAllPageTypes,force:hasRecordId" access="global" >
    <ltng:require styles="/resource/SLDS102/assets/styles/salesforce-lightning-design-system-ltng.css"/>
    <aura:attribute name="recordId" type="Id"/>
    recordId: {!v.recordId}
    <div class="slds-button-group" role="group">
      <button class="slds-button slds-button--neutral">Close Case</button>
      <button class="slds-button slds-button--neutral">Reopen Case</button>
 
    </div>
</aura:component>
