Class DimensionsLabel

java.lang.Object

com.actinarium.rhythm.layer.DimensionsLabel

All Implemented Interfaces:

RhythmSpecLayer

public class DimensionsLabel
extends java.lang.Object
implements RhythmSpecLayer

A layer that draws a small box with dimensions of the current view. Inspect the dimensions of your views at glance. noticing the issues asap. By default, the box is placed in the bottom right corner, but you can change its gravity with setGravity(int). Experimental at the moment, meaning its behavior, appearance, and parameters may change.

Constructor Detail

DimensionsLabel

public DimensionsLabel()

Method Detail

setScaleFactor

public DimensionsLabel setScaleFactor(float scaleFactor)

Set a scale factor that will be applied to width and height of provided bounds

Parameters:

scaleFactor - Scale factor to divide pixels by. Provide DisplayMetrics.density here to display dimensions as dips, DisplayMetrics.scaledDensity to display them as sp, or DEFAULT_SCALE_FACTOR (1f) to get pixels.

Returns:

this for chaining

setGravity

public DimensionsLabel setGravity(int gravity)

Set label gravity. Default is bottom right.

Parameters:

gravity - Desired gravity. Can be combinations, e.g. Gravity.BOTTOM | Gravity.LEFT

Returns:

this for chaining

setBackgroundColor

public DimensionsLabel setBackgroundColor(int color)

Set label background color

Parameters:

color - Label background color, in #AARRGGBB format as usual

Returns:

this for chaining

setTextColor

public DimensionsLabel setTextColor(int color)

Set the color of the label text itself

Parameters:

color - Label text color, in #AARRGGBB format as usual

Returns:

this for chaining

setTextSize

public DimensionsLabel setTextSize(float size)

Set text size

Parameters:

size - Text size, in pixels

Returns:

this for chaining

draw

public void draw(android.graphics.Canvas canvas,
                 android.graphics.Rect drawableBounds)

Description copied from interface: RhythmSpecLayer

Draw itself to the provided canvas within provided bounds according to internal configuration (if any)

Specified by:

draw in interface RhythmSpecLayer

Parameters:

canvas - Canvas for the layer to draw itself to

drawableBounds - Bounds where this layer should draw itself. Since these are the bounds of a RhythmDrawable connected to the view, they are usually the same as the view’s bounds, so you can use this parameter to get the view’s dimensions should you need them.

prettyPrintDips

public static java.lang.String prettyPrintDips(int px,
                                               float scaleFactor)

Sophisticated conversion of pixels to dips with the use of vulgar fractions (to save screen space)

Parameters:

px - Pixels to convert to dips

scaleFactor - Scale factor, should be equal to DisplayMetrics.density for px to dp conversion

Returns:

String formatted with vulgar fraction if needed and possible
