That you use in the click event of each Item the Intent passed had different values, and in the same interface to receive different values to display,,

 
The switch (position) {
Case 0: 
Messages="happens the load type page text zoom function". 
Intent in3=new Intent (VersionChangeActivity. This, VersionDetailsActivity. Class); 
In3. PutExtra (versionmsg, messages). 
StartActivity (in3); 
break; 
Case 1: 
Messages="happens few."; 
Intent in2=new Intent (VersionChangeActivity. This, VersionDetailsActivity. Class); 
In2. PutExtra (versionmsg, messages). 
StartActivity (in2); 
break; 
Case 2: 
Messages="Add APP online update function."; 
Intent in1=new Intent (VersionChangeActivity. This, VersionDetailsActivity. Class); 
In1. PutExtra (versionmsg, messages). 
StartActivity (in1); 
break; 
Case 3: 
Messages="Add dynamic icon guides to help users get started faster -."; 
The Intent in=new Intent (VersionChangeActivity. This, VersionDetailsActivity. Class); 
In the putExtra (" versionmsg ", messages); 
StartActivity (in); 
break; 

Below is the same interface receives the value and show

 
String Msgs=getIntent (). GetStringExtra (" versionmsg "); 
TextView. SetText (Msgs);
