Start Android activity from list of activities -

i working on 1 android app, , in have 1 menu shows list of activity name.upon clicking of item menu should start specific activity.

one way know is,

string classes[]= {"firstactivity","detailactivity"}; intent =new intent(pkg_name+classes[position]);startactivity(i);  

where position=0 or 1. , need write in androidmanifest.xml file below code each activity

<activity         android:name="com.example.day1.detailactivity"          >         <intent-filter>             <action android:name="com.example.day1.detailactivity" />             <category android:name="android.intent.category.default" />          </intent-filter>     </activity> 

but want

<activity android:name=".detailactivity"></activity> 

simple code. dont want use intent-filter please give me alternative can use in case.

or other way round

class classes[] = [ firstactivity.class, detailactivity.class]; intent = new intent(this, classes[position]); startactivity(i); 

then, when want display name of activities, use classes[position].getsimplename();
