Implement ListView's OnItemClickListener, once you handle this event, try to get the location of the row that was clicked.

Once you get it, access that particular row position in the source array (or whatever else you're having). This way, you'll have the data that you want to pass to another activity.

Now use this code:

Intent anotherActivityIntent = new Intent(this, AnotherActivity.class);
anotherActivityIntent.putExtra("my.package.dataToPass",dataFromClickedRow);
startActivity(anotherActivityIntent);

and when the anotherActivityIntent starts the AnotherActivity class, use following code to access the value that you had passed:

Bundle recdData = getIntent().getExtras();
String myVal = recdData.getString("my.package.dataToPass");

Now you have your data in myVal variable. you can use any other data type, whichever you like.
