copied!<p>You're in luck, all of your class' members are already serialzble so your first step is to say that <em>Lecture</em> is Serializable. </p> <pre><code>public class Lecture implements Serializable { public String title; public String startTime; public String endTime; public String day; public boolean classEnabled; public Lecture(String title, String startTime, String endTime, String day, boolean enable){ this.title = title; this.startTime = startTime; this.endTime = endTime; this.day = day; this.classEnabled = enable; } </code></pre> <p>Next, you need to make a default constructor since serialization seems to require that. The last thing is you need to write your object out to a file. I usually use something like the following. Note this is for saving a game state so you might not want to use the cache directory. </p> <pre><code>private void saveState() { final File cache_dir = this.getCacheDir(); final File suspend_f = new File(cache_dir.getAbsoluteFile() + File.separator + SUSPEND_FILE); FileOutputStream fos = null; ObjectOutputStream oos = null; boolean keep = true; try { fos = new FileOutputStream(suspend_f); oos = new ObjectOutputStream(fos); oos.writeObject(this.gameState); } catch (Exception e) { keep = false; Log.e("MyAppName", "failed to suspend", e); } finally { try { if (oos != null) oos.close(); if (fos != null) fos.close(); if (keep == false) suspend_f.delete(); } catch (Exception e) { /* do nothing */ } } } </code></pre> <p>Reading the data back is pretty symmetric to the write so I have left that out for this answer. Also, there are still a lot of caveats to Serialized objects so I suggest you do some Google searches and read up on Java serialization in general. </p>
