如何清除ActiveAndroid中的所有表？

我的Active Android数据库中有大约20-30个表.当我按logoutButton时,我想清除所有表格.我怎么能在ActiveAndroid中做到这一点？

public void logout() {
     //clear all tables
 }

解决方法

sqliteDatabase db = ActiveAndroid.getDatabase();
        List<String> tables = new ArrayList<>();
        Cursor cursor = db.rawQuery("SELECT * FROM sqlite_master WHERE type='table';",null);
        cursor.movetoFirst();
        while (!cursor.isAfterLast()) {
            String tableName = cursor.getString(1);
            if (!tableName.equals("android_Metadata") &&
                    !tableName.equals("sqlite_sequence")) {
                tables.add(tableName);
            }
            cursor.movetoNext();
        }
        cursor.close();
        for (String tableName : tables) {
            db.execsql("DELETE FROM " + tableName);
        }
