Method Detail

minorAxisUpdateLayout

protected boolean minorAxisUpdateLayout(int minorAxis)

Overrides:

minorAxisUpdateLayout in class SimpleViewLayoutState

---

getLayoutMinorAxisMaximumSpan

public float getLayoutMinorAxisMaximumSpan()

Description copied from interface: ViewLayoutState

Get the maximum span of the view along minor axis.
The value is expected to be cached for fast access.
As the default GapBoxView implementations do not use the maximum span of their children the particular layout state may decide not to cache the maximum span value and return preferred span instead to save memory that would otherwise be used for caching variables.

If there is a dedicated variable for this value then that variable gets updated by ViewLayoutState.updateLayout() which usually happens once the view has called View.preferenceChanged() in the parent.
After the value gets updated the layout state must immediately call Parent.minorAxisPreferenceChanged() to notify the parent about the change of minor span.

Specified by:

getLayoutMinorAxisMaximumSpan in interface ViewLayoutState

Overrides:

getLayoutMinorAxisMaximumSpan in class SimpleViewLayoutState

---

setLayoutMinorAxisMaximumSpan

public void setLayoutMinorAxisMaximumSpan(float layoutMinorAxisMaximumSpan)

---

getLayoutMinorAxisMinimumSpan

public float getLayoutMinorAxisMinimumSpan()

Description copied from interface: ViewLayoutState

Get the minimum span of the view along minor axis.
The value is expected to be cached for fast access.
By default GapBoxView implementations do not use the minimum span of their children so the particular layout state may decide not to cache the minimum span value and return preferred span instead to save memory that would otherwise be used for caching variables.

If there is a dedicated variable for this value then that variable should be updated during ViewLayoutState.updateLayout() which usually happens once the view has called View.preferenceChanged() in the parent.
After the value gets updated the layout state must immediately call Parent.minorAxisPreferenceChanged() to notify the parent about the change of minor span.

Specified by:

getLayoutMinorAxisMinimumSpan in interface ViewLayoutState

Overrides:

getLayoutMinorAxisMinimumSpan in class SimpleViewLayoutState

setLayoutMinorAxisMinimumSpan

public void setLayoutMinorAxisMinimumSpan(float layoutMinorAxisMinimumSpan)
