<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="@android:id/list"

<TextView

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_item_event"

public class SimpleCalendarView extends FrameLayout {
private ImageView calendarImageView = null;
private TextView calendarMonthTextView = null;
private TextView calendarDayTextView = null;
public SimpleCalendarView(Context context) {
super(context);
}
public SimpleCalendarView(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
setUpImageView(context);
setUpDayView(context);
setUpMonthView(context);
/* Add child views to this object. */
addView(calendarImageView);
addView(calendarMonthTextView);
addView(calendarDayTextView);
}
private void setUpImageView(final Context context) {
calendarImageView = new ImageView(context);
calendarImageView.setImageResource(R.drawable.bg_calendar);
calendarImageView.setScaleType(ImageView.ScaleType.FIT_XY);
}
private void setUpMonthView(final Context context) {
calendarMonthTextView = new TextView(context);
calendarMonthTextView.setTextSize(7);
calendarMonthTextView.setTypeface(Typeface.DEFAULT_BOLD);
calendarMonthTextView.setPadding(0, 4, 0, 0);
calendarMonthTextView.setTextColor(Color.WHITE);
calendarMonthTextView.setGravity(Gravity.CENTER_HORIZONTAL);
}
private void setUpDayView(final Context context) {

calendarDayTextView.setGravity(Gravity.CENTER_HORIZONTAL);
}
public void setDayOfMonth(final int day) {
this.calendarDayTextView.setText(Integer.toString(day));
}
public void setMonth(final String month) {
