Usage

From source file:com.acbelter.scheduleview.ScheduleView.java

private void positionItemViews() {
    if (mAdapter == null) {
        return;/*from w w  w .jav  a 2  s  .  c  o  m*/
    }

    View child;
    final int right = mViewWidth - getPaddingRight() - mItemPaddingRight;
    for (int i = 0; i < mAdapter.getCount(); i++) {
        child = getChildAt(i);
        int width = child.getMeasuredWidth();
        int height = child.getMeasuredHeight();

        GeneralScheduleItem item = mAdapter.getItem(i);

        int top = mListY + mInternalPaddingTop + getPaddingTop() + mTimeMarkHeight / 2
                + calculateDistance(mStartTime, getTimeInMillis(item.getStartTime()));

        child.layout(right - width, top, right, top + height);
    }
