- * If alignment was defined along a given axis then the component
- * is taken as <em>flexible</em> in that direction. If no alignment was set,
+ * The flexibility of a view is therefore influenced by its alignment which is,
+ * in turn, typically defined by setting the
+ * {@link LayoutParams#setGravity(int) gravity} property of the child's layout parameters.
+ * If either a weight or alignment were defined along a given axis then the component
+ * is taken as <em>flexible</em> in that direction. If no weight or alignment was set,

- * <h5>Limitations</h5>

- * GridLayout does not provide support for the principle of <em>weight</em>, as defined in
- * {@link LinearLayout.LayoutParams#weight}. In general, it is not therefore possible

- * <p>
- * Some common use-cases may nevertheless be accommodated as follows.
- * To place equal amounts of space around a component in a cell group;
- * use {@link #CENTER} alignment (or {@link LayoutParams#setGravity(int) gravity}).
- * For complete control over excess space distribution in a row or column;
- * use a {@link LinearLayout} subview to hold the components in the associated cell group.
- * When using either of these techniques, bear in mind that cell groups may be defined to overlap.
