Titanium.Android.RemoteViews

proxyAndroidsince 1.6

The Titanium binding of Android RemoteViews.

RemoteViews is an API for referencing and updating a remote view hierarchy that lives in another process, for example, in a 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 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.
