Body
The following code excerpt can be used to create multiple tables in an SQLite Cipher database: Use these imports: <pre><code>import java.sql.SQLException; import net.sqlcipher.database.SQLiteDatabase; import net.sqlcipher.database.SQLiteOpenHelper; import android.content.ContentValues; import android.content.Context; import android.database.Cursor; import android.util.Log; /** Helper to the database, manages versions and creation */ public class DBAdapter extends SQLiteOpenHelper { private static final String DATABASE_NAME = "Test"; private static final int DATABASE_VERSION = 1; // Table name public static final String TABLE_1 = "Table1"; public static final String TABLE_2 = "Table2"; // Column names for Table1 table static final String KEY_PASSWORD = "password"; static final String KEY_USER = "user"; // Column names for Table2 table static final String KEY_EVENT = "event"; static final String KEY_USERNAME = "username"; public DBAdapter(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } @Override public void onCreate(SQLiteDatabase db) { String sql1 = "create table " + Table_1 + " (" + KEY_USER + " text primary key, " + KEY_PASSWORD + " text not null);"; String sql2 = "create table " + Table_2 + " (" + KEY_EVENT + " text primary key, " + KEY_USERNAME + " text not null FOREIGN KEY(" + KEY_USERNAME + ") REFERENCES " + TABLE_1 + "(" + KEY_USER + "));"; db.execSQL(sql1); db.execSQL(sql2); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { if (oldVersion >= newVersion){ return; } String sql = null; if (oldVersion == 1) sql = "alter table " + TABLE_1 + " add note text;"; if (oldVersion == 2) sql = ""; Log.d("EventsData", "onUpgrade : " + sql); if (sql != null) db.execSQL(sql); } public Cursor getAllUsers(String username, SQLiteDatabase db){ return db.query(TABLE_1, ...); } public Cursor getAllEvents(String event, SQLiteDatabase db){ return db.query(TABLE_2, ...); } } </code></pre> Now you can do all the CRUD methods for both tables. Just make sure that each method has an <code>SQLiteDatabase</code> as an argument as shown in the <code>getAllUsers()</code> method.

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.
