RemoteViews

extends Object
implements Parcelable LayoutInflater.Filter
java.lang.Object
   ↳ android.widget.RemoteViews

Class Overview

A class that describes a view hierarchy that can be displayed in another process. The hierarchy is inflated from a layout resource file, and this class provides some basic operations for modifying the content of the inflated hierarchy.

Summary

Nested Classes
public class RemoteViews.ActionException Exception to send when something goes wrong executing an action  
public class RemoteViews.RemoteView This annotation indicates that a subclass of View is alllowed to be used with the RemoteViews mechanism. 
Constants
Creator<RemoteViews> CREATOR Parcelable.Creator that instantiates RemoteViews objects
[Expand]
Inherited Constants
From interface android.os.Parcelable
Public Constructors
RemoteViews(String packageName, int layoutId)
Create a new RemoteViews object that will display the views contained in the specified layout file.
RemoteViews(Parcel parcel)
Reads a RemoteViews object from a parcel.
Public Methods
View apply(Context context, ViewGroup parent)
Inflates the view hierarchy represented by this object and applies all of the actions.
int describeContents()
Describe the kinds of special objects contained in this Parcelable's marshalled representation.
int getLayoutId()
String getPackage()
boolean onLoadClass(Class clazz)
Hook to allow clients of the LayoutInflater to restrict the set of Views that are allowed to be inflated.
void reapply(Context context, View v)
Applies all of the actions to the provided view.
void setChronometer(int viewId, long base, String format, boolean running)
Equivalent to calling Chronometer.setBase, Chronometer.setFormat, and Chronometer.start() or Chronometer.stop().
void setImageViewResource(int viewId, int srcId)
Equivalent to calling ImageView.setImageResource
void setImageViewUri(int viewId, Uri uri)
Equivalent to calling ImageView.setImageURI
void setProgressBar(int viewId, int max, int progress, boolean indeterminate)
Equivalent to calling ProgressBar.setMax, ProgressBar.setProgress, and ProgressBar.setIndeterminate
void setTextViewText(int viewId, CharSequence text)
Equivalent to calling TextView.setText
void setViewVisibility(int viewId, int visibility)
Equivalent to calling View.setVisibility

Constants

public static final Creator<RemoteViews> CREATOR

Parcelable.Creator that instantiates RemoteViews objects

Public Constructors

public RemoteViews (String packageName, int layoutId)

Create a new RemoteViews object that will display the views contained in the specified layout file.

Parameters
packageName Name of the package that contains the layout resource
layoutId The id of the layout resource

public RemoteViews (Parcel parcel)

Reads a RemoteViews object from a parcel.

Public Methods

public View apply (Context context, ViewGroup parent)

Inflates the view hierarchy represented by this object and applies all of the actions.

Caller beware: this may throw

Parameters
context Default context to use
parent Parent that the resulting view hierarchy will be attached to. This method does not attach the hierarchy. The caller should do so when appropriate.
Returns
  • The inflated view hierarchy

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

Returns
  • a bitmask indicating the set of special object types marshalled by the Parcelable.

public int getLayoutId ()

public String getPackage ()

public boolean onLoadClass (Class clazz)

Hook to allow clients of the LayoutInflater to restrict the set of Views that are allowed to be inflated.

Parameters
clazz The class object for the View that is about to be inflated
Returns
  • True if this class is allowed to be inflated, or false otherwise

public void reapply (Context context, View v)

Applies all of the actions to the provided view.

Caller beware: this may throw

Parameters
v The view to apply the actions to. This should be the result of the apply(Context, ViewGroup) call.

public void setChronometer (int viewId, long base, String format, boolean running)

Equivalent to calling Chronometer.setBase, Chronometer.setFormat, and Chronometer.start() or Chronometer.stop().

Parameters
viewId The id of the view whose text should change
base The time at which the timer would have read 0:00. This time should be based off of SystemClock.elapsedRealtime().
format The Chronometer format string, or null to simply display the timer value.
running True if you want the clock to be running, false if not.

public void setImageViewResource (int viewId, int srcId)

Equivalent to calling ImageView.setImageResource

Parameters
viewId The id of the view whose drawable should change
srcId The new resource id for the drawable

public void setImageViewUri (int viewId, Uri uri)

Equivalent to calling ImageView.setImageURI

Parameters
viewId The id of the view whose drawable should change
uri The Uri for the image

public void setProgressBar (int viewId, int max, int progress, boolean indeterminate)

Equivalent to calling ProgressBar.setMax, ProgressBar.setProgress, and ProgressBar.setIndeterminate

Parameters
viewId The id of the view whose text should change
max The 100% value for the progress bar
progress The current value of the progress bar.
indeterminate True if the progress bar is indeterminate, false if not.

public void setTextViewText (int viewId, CharSequence text)

Equivalent to calling TextView.setText

Parameters
viewId The id of the view whose text should change
text The new text for the view

public void setViewVisibility (int viewId, int visibility)

Equivalent to calling View.setVisibility

Parameters
viewId The id of the view whose visibility should change
visibility The new visibility for the view

public void writeToParcel (Parcel dest, int flags)

Flatten this object in to a Parcel.

Parameters
dest The Parcel in which the object should be written.
flags Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
