Example 31 with Calendar

use of android.icu.util.Calendar in project android_frameworks_base by crdroidandroid.

the class CalendarViewLegacyDelegate method setMinDate.

@Override
public void setMinDate(long minDate) {
    mTempDate.setTimeInMillis(minDate);
    if (isSameDate(mTempDate, mMinDate)) {
        return;
    }
    mMinDate.setTimeInMillis(minDate);
    // make sure the current date is not earlier than
    // the new min date since the latter is used for
    // calculating the indices in the adapter thus
    // avoiding out of bounds error
    Calendar date = mAdapter.mSelectedDate;
    if (date.before(mMinDate)) {
        mAdapter.setSelectedDay(mMinDate);
    }
    // reinitialize the adapter since its range depends on min date
    mAdapter.init();
    if (date.before(mMinDate)) {
        setDate(mTempDate.getTimeInMillis());
    } else {
        // we go to the current date to force the ListView to query its
        // adapter for the shown views since we have changed the adapter
        // range and the base from which the later calculates item indices
        // note that calling setDate will not work since the date is the same
        goTo(date, false, true, false);
