android - what is the difference between layout_weight and using dp? -


i want create scalable view.

should prefer using linear layout property: layout_weight

or using layout_width: x dp ? (which relative , not apolute pixels)

what difference?

this highly depends on exact use case.

layout_weight depends on number , size of other views in same viewgroup.

dp (density-independant pixels) depends on density of device.

usually, dp used have view displayed @ same physical size on devices different screen densities, while weight makes sure view fills percentage of parent viewgroup.
