Field Detail

value

public final float value

The value of this screen density in DPI units.

scaleRatio

public final float scaleRatio

The value of scale ratio specific for this screen density.

Method Detail

values

public static Screen.ScreenDensity[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Screen.ScreenDensity c : Screen.ScreenDensity.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Screen.ScreenDensity valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

resolve

public static Screen.ScreenDensity resolve(float densityDpi)

Resolves an instance of ScreenDensity according to the given densityDpi.

Parameters:

densityDpi - The value value of the desired density to resolve.

Returns:

Resolved screen density instance or UNKNOWN if there is no screen density with the requested density value.
