Custom font in widgets

I am trying to create a simple Android widget that shows the time but uses a custom font. Does anyone know how to do this? I tried this: Problem showing time using custom font

But that won't work. The first getAssets () won't work because it needs context, and if I remove the line that sets the custom font after a couple of seconds, I get a failed transaction error .

Can anyone help or give me a link for a tutorial? Also, is it helpful to update the time with a timer?

My LWidget.java code

public class LWidget extends AppWidgetProvider {

//=============================================================================================
//On Update
//=============================================================================================


    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,
    int[] appWidgetIds) {
        Timer timer = new Timer();
        timer.scheduleAtFixedRate(new MyTime(context, appWidgetManager), 1, 1000);



        //views.setImageViewBitmap(R.id.TimeView, buildUpdate(time));





    }
//=============================================================================================
//Timer class
//=============================================================================================

    private class MyTime extends TimerTask {
        RemoteViews remoteViews;
        AppWidgetManager appWidgetManager;
        ComponentName thisWidget;
        DateFormat timeformat = new SimpleDateFormat("kk:mm");
        public MyTime(Context context, AppWidgetManager appWidgetManager) {
        this.appWidgetManager = appWidgetManager;
        remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
        thisWidget = new ComponentName(context, LWidget.class);
    }

    @Override
    public void run() {
        Calendar ci = Calendar.getInstance();
        String time = timeformat.format(ci.getTime());
        remoteViews.setTextViewText(R.id.widget_textview,"Time = " + time);
        remoteViews.setImageViewBitmap(R.id.widget_imageview, buildUpdate(time));
        appWidgetManager.updateAppWidget(thisWidget, remoteViews);
        }
    }

//=============================================================================================
//bitmap font
//=============================================================================================
    public Bitmap buildUpdate(String time) 
{
        Bitmap myBitmap = Bitmap.createBitmap(160, 84, Bitmap.Config.ARGB_4444);
        Canvas myCanvas = new Canvas(myBitmap);
        Paint paint = new Paint();

        //if I remove the comment here, getAssets() will not work

        //Typeface clock = Typeface.createFromAsset(this.getAssets(),"fonts/Crysta.ttf");
        paint.setAntiAlias(true);
        paint.setSubpixelText(true);
       // paint.setTypeface(clock);
        paint.setStyle(Paint.Style.FILL);
        paint.setColor(Color.WHITE);
        paint.setTextSize(65);
        paint.setTextAlign(Align.CENTER);
        myCanvas.drawText(time, 80, 60, paint);
        return myBitmap;
 }




//=============================================================================================
//On receive
//=============================================================================================
@Override
    public void onReceive(Context context, Intent intent) {
            // v1.5 fix that doesn't call onDelete Action
            final String action = intent.getAction();
            if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
            final int appWidgetId = intent.getExtras().getInt(
            AppWidgetManager.EXTRA_APPWIDGET_ID,
            AppWidgetManager.INVALID_APPWIDGET_ID);
            if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
                this.onDeleted(context, new int[] { appWidgetId });
            }
            } else {
                super.onReceive(context, intent);
            }
    }

}

      

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

Instead of a timer, you should use AlarmManager

. You cannot use a timer because :

AppWidgetProvider

is an extension BroadcastReceiver

, your process is not guaranteed to continue running after callback methods return.

Use the code here for reference.



getAssets () won't work because it needs context

onUpdate()

provides Context

, no?

ok try this way:

static Context con;



Typeface clock = Typeface.createFromAsset (con.getAssets (), "fonts / KacstLetter.ttf");
