Prototype

public final int getMeasuredWidth()

Document

Like #getMeasuredWidthAndState() , but only returns the raw width component (that is the result is masked by #MEASURED_SIZE_MASK ).

Usage

From source file:com.awrtechnologies.carbudgetsales.hlistview.widget.HListView.java

/**
 * Measures the height of the given range of children (inclusive) and returns the height with this ListView's padding and divider
 * heights included. If maxHeight is provided, the measuring will stop when the current height reaches maxHeight.
 * //  w w  w .  ja  va  2 s. c o  m
 * @param heightMeasureSpec
 *           The height measure spec to be given to a child's {@link View#measure(int, int)}.
 * @param startPosition
 *           The position of the first child to be shown.
 * @param endPosition
 *           The (inclusive) position of the last child to be shown. Specify {@link #NO_POSITION} if the last child should be the
 *           last available child from the com.awrtechnologies.carbudgetsales.adapter.
 * @param maxWidth
 *           The maximum height that will be returned (if all the children don't fit in this value, this value will be returned).
 * @param disallowPartialChildPosition
 *           In general, whether the returned height should only contain entire children. This is more powerful--it is the first
 *           inclusive position at which partial children will not be allowed. Example: it looks nice to have at least 3
 *           completely visible children, and in portrait this will most likely fit; but in landscape there could be times when
 *           even 2 children can not be completely shown, so a value of 2 (remember, inclusive) would be good (assuming
 *           startPosition is 0).
 * @return The height of this ListView with the given children.
