How to scroll/move text within TextView on home screen widget ?

 Hi All,

I have created a widget to be displayed on android emulator's home
screen to display some long text. In my main.xml layout file i've
already set TextView properties like singleLine="true",
ellipsize="marquee", focusable="true" etc, but still when my widget is
displayed on home screen text does not move/scroll.

----------------- main.xml layout file ------------------------

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=" 
android:layout_height="wrap_content" android:background="@drawable/
<TextView android:id="@+id/widget_textview"
android:focusable="true" />

----------------- end of main.xml layout file ------------------------

------------- My file ----------------------


import android.util.Log;
import android.widget.RemoteViews;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;

public class WeatherWidget extends AppWidgetProvider{

private static final String TAG = "WeatherWidget";

public void onUpdate(Context context, AppWidgetManager
appWidgetManager, int[] appWidgetIds)
Log.d("WEATHER-WIDGET", "onUpdate(): ");

final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to
this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];

// Create an Intent to launch ExampleActivity
Intent intent = new Intent(context, Weather.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);

Log.i("WEATHER-WIDGET", " Create and Attach Text-view click handler
// Get the layout for the App Widget and attach an on-click listener
to the button
RemoteViews views = new RemoteViews(context.getPackageName(),
views.setOnClickPendingIntent( , pendingIntent);

// Tell the AppWidgetManager to perform an update on the current App
appWidgetManager.updateAppWidget(appWidgetId, views);

----------------- End of WidgetProvider file--------------------

When i add widget on home screen than only some part of text is
displayed as " Latest Weather Infor" but i would like to write the
code in such a way that the complete text should scroll till the
complete string/text is displayed.

Please suggest whether i need to change my layout file or what logic i
can write so that i can scroll the text.

Thanks in advance,

1. alertdialog, under what circumstances will invoking .show directly cause problems?

When creating an AlertDialog...I have noticed in some cases, if you
invoke .show directly, you
get a leaked dialog error when you rotate the phone.
In other cases you don't.

If you don't call .show and use showDialog from the activity you don't
see the leaked dialogs.
Are there some cases when you can use .show?

Or is it just dumb luck if you don't see a problem?

Dear All,

I'm trying to write an App that continuously record audio in memory (in a
circular buffer).

Could anyone point me towards a piece of code (perhaps in the kernel) that
shows how to best to this ?
