Constant Value: 160 (0x000000a0)

DENSITY_TV

public static final int DENSITY_TV

This is a secondary density, added for some common screen configurations. It is recommended that applications not generally target this as a first class density -- that is, don't supply specific graphics for this density, instead allow the platform to scale from other densities (typically DENSITY_HIGH) as appropriate. In most cases (such as using bitmaps in Drawable) the platform can perform this scaling at load time, so the only cost is some slight startup runtime overhead.

This density was original introduced to correspond with a 720p TV screen: the density for 1080p televisions is DENSITY_XHIGH, and the value here provides the same UI size for a TV running at 720p. It has also found use in 7" tablets, when these devices have 1280x720 displays.

Constant Value: 213 (0x000000d5)

DENSITY_XHIGH

public static final int DENSITY_XHIGH

Constant Value: 480 (0x000001e0)

DENSITY_XXXHIGH

public static final int DENSITY_XXXHIGH

Standard quantized DPI for extra-extra-extra-high-density screens. Applications should not generally worry about this density; relying on XHIGH graphics being scaled up to it should be sufficient for almost all cases. A typical use of this density would be 4K television screens -- 3840x2160, which is 2x a traditional HD 1920x1080 screen which runs at DENSITY_XHIGH.

Constant Value: 640 (0x00000280)

DENSITY_DEVICE_STABLE

public static final int DENSITY_DEVICE_STABLE

The device's stable density.

This value is constant at run time and may not reflect the current display density. To obtain the current density for a specific display, use densityDpi.

density

public float density

The logical density of the display. This is a scaling factor for the Density Independent Pixel unit, where one DIP is one pixel on an approximately 160 dpi screen (for example a 240x320, 1.5"x2" screen), providing the baseline of the system's display. Thus on a 160dpi screen this density value will be 1; on a 120 dpi screen it would be .75; etc.

This value does not exactly follow the real screen size (as given by xdpi and ydpi), but rather is used to scale the size of the overall UI in steps based on gross changes in the display dpi. For example, a 240x320 screen will have a density of 1 even if its width is 1.8", 1.3", etc. However, if the screen resolution is increased to 320x480 but the screen size remained 1.5"x2" then the density would be increased (probably to 1.5).

densityDpi

public int densityDpi

The screen density expressed as dots-per-inch. May be any one of the DENSITY_ constants defined above. New constants are frequently added, and constants added on new Android versions may be backported to previous Android versions, so applications should not strongly rely on density matching one of the enum constants.
Value is DENSITY_LOW, DENSITY_140, DENSITY_MEDIUM, DENSITY_180, DENSITY_200, DENSITY_TV, DENSITY_220, DENSITY_HIGH, DENSITY_260, DENSITY_280, DENSITY_300, DENSITY_XHIGH, DENSITY_340, DENSITY_360, DENSITY_390, DENSITY_400, DENSITY_420, DENSITY_440, DENSITY_450, DENSITY_XXHIGH, DENSITY_520, DENSITY_560, DENSITY_600, or DENSITY_XXXHIGH

heightPixels

public int heightPixels

The absolute height of the available display size in pixels.

scaledDensity

public float scaledDensity

This field was deprecated in API level 34.
this scalar factor is no longer accurate due to adaptive non-linear font scaling. Please use TypedValue.applyDimension(int, float, DisplayMetrics) or TypedValue.deriveDimension(int, float, DisplayMetrics) to convert between SP font sizes and pixels.

A scaling factor for fonts displayed on the display. This is the same as density, except that it may be adjusted in smaller increments at runtime based on a user preference for the font size.

widthPixels

public int widthPixels

The absolute width of the available display size in pixels.

xdpi

public float xdpi

The exact physical pixels per inch of the screen in the X dimension.

ydpi

public float ydpi

The exact physical pixels per inch of the screen in the Y dimension.

DisplayMetrics

public DisplayMetrics ()

equals

public boolean equals (DisplayMetrics other)

Returns true if these display metrics equal the other display metrics.

equals

public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

setTo

public void setTo (DisplayMetrics o)

setToDefaults

public void setToDefaults ()

toString

public String toString ()

Returns a string representation of the object.
