# Titanium.Android.RemoteViews
The Titanium binding of Android RemoteViews.
# Overview
RemoteViews
is an API for referencing and updating a remote view hierarchy that
lives in another process, for example, in a Titanium.Android.Notification.
To create a remote view hierarchy, you must define an Android XML layout for the views
you want to display, and place the XML file in the platform/android/res/layout
inside your
project folder. See the examples for a sample XML layout and sample code for creating a
remote view.
To use a remote view hierarchy in a notification, see Titanium.Android.Notification.contentView.
Because the remote view hierarchy belongs to another process, you cannot call methods on it
directly, but you can call methods on the RemoteViews
object to update views in the
heirarchy by ID. To reference a view inside the layout, use the
Titanium.App.Android.R object to reference the view's ID. For example, if you have a
view with the ID notify_imageview
, you can refer to it using:
Ti.App.Android.R.id.notify_imageview

# Examples
# Create a Remote View
The following code excerpt creates a RemoteViews
object based on a custom layout
called custom_layout.xml
, and set a label's text.
var AppR = Ti.App.Android.R;
var customLayout = Ti.Android.createRemoteViews({ layoutId: AppR.layout.custom_layout });
customLayout.setTextViewText(AppR.id.custom_text, "Click Me!");
This example uses a simple custom layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView android:id="@+id/custom_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
android:textColor="#aaff0000"
android:textStyle="italic"
android:gravity="center"
android:text="Hello, I am a TextView" />
</LinearLayout>
The layout file for this example must be placed in
platform/android/res/layout/custom_layout.xml
.
# Properties
# apiName READONLY
The name of the API that this proxy corresponds to.
The value of this property is the fully qualified name of the API. For example, Titanium.UI.Button
returns Ti.UI.Button
.
# bubbleParent
Indicates if the proxy will bubble an event to its parent.
Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.
Default: true
# layoutId CREATION ONLY
Android layout resource ID for the view to display. Required.
To define a custom layout resource in your application, the XML layout file
should be placed in platform/android/res/layout
folder inside your project folder.
Use R to reference the ID of the layout.
# lifecycleContainer
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.
# packageName CREATION ONLY
Package name that the resource ID lives in. Optional.
# Methods
# addEventListener
Adds the specified callback as an event listener for the named event.
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
callback | Callback<Titanium.Event> | Callback function to invoke when the event is fired. |
Returns
- Type
- void
# applyProperties
Applies the properties to the proxy.
Properties are supplied as a dictionary. Each key-value pair in the object is applied to the proxy such that myproxy[key] = value.
Parameters
Name | Type | Description |
---|---|---|
props | Dictionary | A dictionary of properties to apply. |
Returns
- Type
- void
# fireEvent
Fires a synthesized event to any registered listeners.
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
event | Dictionary | A dictionary of keys and values to add to the Titanium.Event object sent to the listeners. |
Returns
- Type
- void
# removeEventListener
Removes the specified callback as an event listener for the named event.
Multiple listeners can be registered for the same event, so the
callback
parameter is used to determine which listener to remove.
When adding a listener, you must save a reference to the callback function in order to remove the listener later:
var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);
To remove the listener, pass in a reference to the callback function:
window.removeEventListener('click', listener);
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
callback | Callback<Titanium.Event> | Callback function to remove. Must be the same function passed to |
Returns
- Type
- void
