Constructor Detail

ExpandableGridView

public ExpandableGridView(android.content.Context context)

Creates a new grid view, which can contain multiple groups, which can individually be expanded to show their children.

Parameters:

context - The context, which should be used by the view, as an instance of the class Context. The context may not be null

ExpandableGridView

public ExpandableGridView(android.content.Context context,
                          android.util.AttributeSet attributeSet)

Creates a new grid view, which can contain multiple groups, which can individually be expanded to show their children.

Parameters:

context - The context, which should be used by the view, as an instance of the class Context. The context may not be null

attributeSet - The attribute set, the view's attributes should be obtained from, as an instance of the type AttributeSet or null, if no attributes should be obtained

ExpandableGridView

public ExpandableGridView(android.content.Context context,
                          android.util.AttributeSet attributeSet,
                          int defaultStyle)

Creates a new grid view, which can contain multiple groups, which can individually be expanded to show their children.

Parameters:

context - The context, which should be used by the view, as an instance of the class Context. The context may not be null

attributeSet - The attribute set, the view's attributes should be obtained from, as an instance of the type AttributeSet or null, if no attributes should be obtained

defaultStyle - The default style to apply to this view. If 0, no style will be applied (beyond what is included in the theme). This may either be an attribute resource, whose value will be retrieved from the current theme, or an explicit style resource

ExpandableGridView

public ExpandableGridView(android.content.Context context,
                          android.util.AttributeSet attributeSet,
