The AndroidX library includes the Architecture Components , which you can use to design robust, testable, and maintainable apps. The layouts in your app can bind to the data in the Architecture Components, which already help you manage the UI controllers lifecycle and notify about changes in the data.

This page shows how to incorporate the Architecture Components to your app to further enhance the benefits of using the Data Binding Library. You can use LiveData objects as the data binding source to automatically notify the UI about changes in the data. Unlike objects that implement Observable —such as observable fields — LiveData objects know about the lifecycle of the observers subscribed to the data changes.

In Android Studio version 3. To use a LiveData object with your binding class, you need to specify a lifecycle owner to define the scope of the LiveData object. The following example specifies the activity as the lifecycle owner after the binding class has been instantiated:. In the ViewModel component, you can use the LiveData object to transform the data or merge multiple data sources.

The following example shows how to transform the data in the ViewModel :. The Data Binding Library works seamlessly with ViewModel components, which expose the data that the layout observes and reacts to its changes. Using ViewModel components with the Data Binding Library allows you to move UI logic out of the layouts and into the components, which are easier to test.

The Data Binding Library ensures that the views are bound and unbound from the data source when needed. To use the ViewModel component with the Data Binding Library, you must instantiate your component, which inherits from the ViewModel class, obtain an instance of your binding class, and assign your ViewModel component to a property in the binding class. The following example shows how to use the component with the library:.

In your layout, assign the properties and methods of your ViewModel component to the corresponding views using binding expressions, as shown in the following example:.

You can use a ViewModel component that implements the Observable to notify other app components about changes in the data, similar to how you would use a LiveData object. There are situations where you might prefer to use a ViewModel component that implements the Observable interface over using LiveData objects, even if you lose the lifecycle management capabilities of LiveData.

To implement an observable ViewModel component, you must create a class that inherits from the ViewModel class and implements the Observable interface. You can provide your custom logic when an observer subscribes or unsubscribes to notifications using the addOnPropertyChangedCallback and removeOnPropertyChangedCallback methods.

You can also provide custom logic that runs when properties change in the notifyPropertyChanged method. The following code example shows how to implement an observable ViewModel :.

Can anyone help me and advice how can I access controls used in fragments by their ID in the controller? So your code this. When using explicit ids there is a static Fragment. I guess you have to use it like this:.

Accessing controls inside a fragment depends on how your fragment was created in the first place. Here is a list of cases with respective API to use to get the control reference:. Use Fragment. Avoid concatenating ID parts or relying on the syntax of the global ID, as mentioned in the comment as well as in the documentation :.

Do not rely on the specific prefixing syntax because it may change at some point. Always use methods like byId and createId. To make it work without explicit fragment ID and without static Fragment.

A rich text based editor provides syntax highlighting, well-formed validation, schema aware validation for XSD 1. Each element within the document can be pivoted allowing its children to appear as columns within a table.

The text and tabular views can also be seen side by side in a split view making it easy to see the impact of changes made in the tabular view. The standard tree based paradigm is often very limiting when editing repeated sets of data. In the tree view the XML document is represented as hierarchy of nodes. Each element or attribute being represented as a leaf.

In the table view a group of element of the same type are represented as a table, each row in the table represents an element, and each cell a child element or attribute. Any group of XML elements can be represented as a tree or table, and each group can be switch between views using the context menu. Changes to the grid view are instantly reflected in the code view, and changes to the code are reflected in the model when it is selected again.

The selection in the grid view is also tracked in the source code, in this case, as a column is selected in the grid view all of the corresponding child elements are selected in the code view.

So you are presented with the attributes or elements that are permitted, at the current location in the file. Annotations are read from the XML Schema and presented as tooltips, to provide context sensitive help. Errors reported in real time as you type, and shown inline within the XML document and in the error window.

This section summarizes Teiid Designer features for creating and editing existing model objects contained in your models. Each metamodel type has a set of parent-child relationships that establish constraints on what can be created and where.

You cannot, for example, create a column attribute in a stored procedure, nor can you create a mapping class column in a Web service operation's output message. The Teiid Designer provides a common set of actions to create new children of these models as well as children of children.

Step 1 - Select the parent object to which you want to add a child. For example, you can add a package to a package or an attribute to a class.

Step 2 - Right-click on a container object. From the pop-up menu, select New Child. You can now select the child object you would like to add. Step 3 - The new model object displays on the diagram and is highlighted for renaming. Step 1 - Select the row for the parent object to which you want to add a child.

For example to add a column, click the Base Table tab and select base table row. Step 2 - Right-click on a table row. Step 3 - The selected tab in the Table Editor changes to the tab for the child object type, the new model object row is displayed and the row's name table cell is highlighted for renaming. Step 1 - Select the object to which you want to add a sibling.

For example, you can add a column sibling to a column. Step 2 - Right-click on that object. From the pop-up menu, select New Sibling. You can now select the sibling object you would like to add. Step 1 - Select the row for the object to which you want to add a sibling. Step 2 - Right-click on a row. Step 1 - Select two objects you wish to associate.

For example, select columns in different base tables. Step 2 - Right-click. Step 3 - The new relationship link is displayed in the diagram. The Column, Foreign Key, Primary Key reference properties are properly set on the selected columns, new primary key and new foreign key.

Step 2 - Drag the column to another table and drag over a column and drop onto this column. The target column should highlight in Yellow. In addition to the simple new object actions, Teiid Designer provides New Child and New Sibling wizards for children of view and source relational models.

Namely tables, views, procedures and indexes. The menu now looks like:. The Create Relational Table Wizard , shown below, allows creating a complete relational table including columns, unique keys, foreign keys definition and indexes. The Create Relational Procedure Wizard , shown below, allows creating a complete relational Procedure including columns, unique keys, foreign keys definition and indexes. The relational procedure object can represent different types of procedures, including a standard procedure, source function pushdown function and native query procedures.

Note that user defined functions can be modeled in a view model. The second dialog customizes the Create Relational Procedure dialog based on your selected type.

The following dialog provides standard procedure data input. Source functions are procedures that are already deployed and accessable on your database. By defining source functions in your relational model, you can call these functions from within your transformation SQL and the functions will be pushed down to your database for execution. Native query procedures are procedures that are already deployed and accessable on your database. Sometimes users will be creating SQL transformations that represent procedures or functions that have yet to be defined.

Below is an example of a query using a getBookInfo function that does not exist yet. The result is a SQL validation error. By selecting the function name and right-clicking, you can now select the Create Function action. You can then choose to create a Source Function i.

In either case, you'll be prompted to select a target Source of View model as the location for your new function. For view models, only tables, procedures standard procedures and user defined functions and indexes can be created. For view tables and procedures, the primary difference in the wizards is that they include a SQL Transformation tab.

User-defined functions can be defined as view model procedures that of type "function". User Defined Functions require additional properties such as Java Class and Method as well as a path to the jar file containing the code as shown below. Cut - Deletes the selected object s and copies it to the clipboard.

Copy - Copies the selected object s to the clipboard. Paste - Pastes the contents of the clipboard to the selected context. Clone - Duplicates the selected object in the same location with the same name; user is able to rename the new object right in the tree. Delete - Deletes the selected object s.

Teiid Designer also provides specialized object editors to handle complex model objects and their unique properties. These editors include:. The Teiid Designer's Transformation Editor enables you to create the query transformations that describe how to derive your virtual metadata information from physical metadata sources or other virtual metadata and how to update the sources.

If a Model Editor is not currently open for the selected object's model, a Model Editor will be opened. After the corresponding transformation diagram is opened in the Diagram Editor, the Transformation Editor is displayed in the lower section of the Diagram Editor. If this virtual class supports updates, the tabs on the bottom of the Transformation Editor allow you to enter SQL for each type of query this virtual class supports. Reconcile target attributes to ensure the symbols in your transformation match the attributes in your virtual metadata class.

You can also set preferences that impact the display of your Transformation Editor. The Transformation Editor toolbar actions are summarized below. Prevew Virtual Data - executes a simple preview query for the target table or procedure of the transformation being edited. Search Transformations - provides a simple way select and edit another transformation based SQL text search criteria. Edit Transformation - provides a simple way to change which transformation to edit without searching in a diagram or the Model Explorer.

Simply click the action and select from a list of views, tables, procedures or operations from the currently edited model. Cursor Position line, column - shows the current line and column position of the insertion cursor. For example, Cursor Position 1,4 indicates that the cursor is presently located at column 4 of line 1. Supports Update - checkbox allows you to enable or disable updates for the current transformation target. If 'Supports Update' is checked, the editor shows four tabs at the bottom for the Select, Update, Insert and Delete transformations.

If 'Supports Update' is unchecked, all updates are disabled and only the Select transformation is displayed. Reconcile - allows you to resolve any discrepancies between the transformation symbols and the target attributes. Pressing this button will display the "Reconcile Virtual Target Attributes" dialog box in which you can resolve discrepancies.

Any Warning or Error messages will be displayed at the bottom of the editor in the messages area. If the SQL validates without error, the message area is not displayed. Criteria Builder - allows you to build a criteria clause in your transformation. The button will enable if the cursor position is within a query that allows a criteria. Pressing the button will launch the Criteria Builder dialog.

If the Criteria Builder is launched inside an existing criteria, that criteria will be displayed for edit, otherwise the Criteria Builder will be initially empty. Expression Builder - allows you to build an expression within your transformation. The button will enable if the cursor position is at a location that allows an expression. Pressing the button will launch the Expression Builder dialog. If the Expression Builder is launched inside an existing expression, that expression will be displayed for edit, otherwise the Expression Builder will be initially empty.

Increase Font Size - increases the font size of all editor text by 1. Decrease Font Size - decreases the font size of all editor text by 1. Some symbol names may remain fully qualified in the event of a duplicate name or if the optimizer is unable to optimize it. When the action is toggled 'OFF', all symbol names will be fully-qualified. Import SQL Text - allows you to import a sql statement from a text file on your file system. Pressing this button will display an import dialog in which you can navigate to the file.

Pressing this button will display an export dialog in which you can choose the location for export. The Transformation Editor context menu can be displayed by Rt-Clicking within the editor's text area. The context menu is show below:. Cut - Copy - Paste - Typical text editor actions to cut, copy or paste text within the editor.

Undo - Redo - Allows you to Undo or Redo the previous action. Find - Displays a Find-Replace Dialog which allows you to search and replace text within the transformation.
