Here is my code for on resume: <pre><code>protected void onResume(){ Log.v(tag, "In onResume!"); Cursor it = mDbHelper.fetchBook(mRowId); super.onResume(); mDbHelper.open(); setRowIdFromIntent(); if (it.moveToFirst()) { populateFields(); } </code></pre> Here is my setRowIdFromIntent method: <pre><code>private void setRowIdFromIntent(){ if(mRowId == null){ Bundle extras = getIntent().getExtras(); mRowId = extras != null ? extras.getLong(DbAdapter.KEY_ROWID) :null; } </code></pre> PopulateFields method which retrieves information from the database if the activity is paused and then resumed, such as when i change from porttrait to landscape. <pre><code>private void populateFields() { if(mRowId != null){ Cursor books = mDbHelper.fetchBook(mRowId); startManagingCursor(books); bookTitle.setText(books.getString(books.getColumnIndexOrThrow(DbAdapter.KEY_BOOK))); bookAuthor.setText(books.getString(books.getColumnIndexOrThrow(DbAdapter.KEY_AUTHOR))); bookIsbn.setText(books.getString(books.getColumnIndexOrThrow(DbAdapter.KEY_ISBN))); ratingBar.setRating(books.getFloat(books.getColumnIndex(DbAdapter.KEY_RATING))); </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
