How to use arbitrary data to select an array for R class in android?

Question

I am new to Java and Android and come from PHP background. I am trying to display a list view based on arbitrary data received from a previous activity. This the code that I am using:

String[] chapter_array = getResources().getStringArray(R.array.view_chapter);
setListAdapter(new ArrayAdapter<String>(this, R.layout.view_surah, chapter_array));

How do I change the "view_chapter" in R.array.view_chapter to make it populate the list from the data received from the last activity.

You probably want to write a custom ListAdapter that pulls the data out of the Intent passed to the new activity (i.e. getIntent().getExtras()) and feed that data into your custom ListAdapter.

The Android developer docs have a good sample on how to write a ListAdapter.

Thanks for the answer. But the same question still stands. The data received from the last activity changed depends on user selection. So how do i make the R.array.(intent_received) changes based on the selection?

Similar to Erich's answer you could simply have the previous activity pass a string in CSV form and do String[] chapter_array = getIntent().getExtras().split(','); or something similar to that
