I'm building a book reader app and currently having some issues on how to move to next or previous chapter.
The fragment that is in charge of showing a list of chapter (basically a ListView). I capture the item with onItemClick:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent = new Intent(getActivity().getApplicationContext(),ReaderActivity.class);
intent.putExtra("name",adapter.getItem(i).getName());
intent.putExtra("url",adapter.getItem(i).getUrl());
startActivity(intent);
}
});
It will start the ReaderActivity and display the content of the book. Now the ReaderActivity has 2 buttons for moving to next/previous chapter. How can I get the data (the name and url) from the ListView?
At the moment I'm thinking of two methods:
-
Calling
finish()onReaderActivityand override theonDestroy()method to call a method to get the next/previous data in the fragment that holds the ListView. -
Passing the whole ArrayList of chapters to
ReaderActivityso it can retrieve the item it wants (probably not a good solution since there are too many chapters).
Is there a better way?
