Constructor Detail

WrapLayoutManager

public WrapLayoutManager(Context context)

Creates an instance of the WrapLayoutManager class.

Parameters:

context - the context to be used

WrapLayoutManager

public WrapLayoutManager(Context context,
                         int orientation)

Creates an instance of the WrapLayoutManager class.

Parameters:

orientation - specifies the layout orientation - HORIZONTAL or VERTICAL

WrapLayoutManager

public WrapLayoutManager(Context context,
                         AttributeSet attrs,
                         int defStyleAttr,
                         int defStyleRes)

Creates an instance of the WrapLayoutManager class.

Method Detail

getGravity

public int getGravity()

Gets the current Gravity that specifies how the empty space left after items are laid out is redistributed.

Returns:

the current Gravity

setGravity

public void setGravity(int gravity)

Sets a new Gravity that will determine how the empty space left after items are laid out will be redistributed.

Parameters:

gravity - the new gravity

getLineSpacing

public int getLineSpacing()

Gets a value in pixels indicating the space that will be left between each line with items.

Returns:

the current line spacing

setLineSpacing

public void setLineSpacing(int lineSpacing)

Sets a new value in pixels indicating the space that will be left between each line with items.

Parameters:

lineSpacing - the line spacing

getMinimumItemSpacing

public int getMinimumItemSpacing()

Gets the minimum item spacing between items that are laid out on a single line. The spacing is minimum because it may increase depending on the current gravity.

Returns:

the current minimum item spacing

setMinimumItemSpacing

public void setMinimumItemSpacing(int minimumItemSpacing)

Sets the minimum item spacing between items that are laid out on a single line. The spacing is minimum because it may increase depending on the current gravity.

Parameters:

minimumItemSpacing - the minimum item spacing
