An Android custom view to display digits rendered as dots in a grid, with a style like a 1970s LED clock.

#DotMatrixView

This is an Android library project providing a custom view that can display things on a grid of dots. When the displayed value changes, the dots that are changing fade in/out to mimic persistence of vision and the speed of reaction of 1980s style LED spots.

##What does it look like?

##Usage

Link the Android library project into your app project, then add it to your layout XML.

Be sure to add this namespace to the parent layout element, e.g.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

This example uses most of the current features of DotMatrixView:

<com.escapeindustries.dotmatrix.MatrixDisplay
android:id="@+id/surfacegrid"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
app:backgroundColor="@android:color/black"
app:dotColor_changeListDim="@array/dim_color_change_list"
app:dotColor_changeListLit="@array/lit_color_change_list"
app:dotColor_changeListTiming="@array/color_change_timings"
app:dotColor_changeUpdater="countdown_color_updates"
app:dotColor_staticDim="@color/pink"
app:dotColor_staticLit="@color/dullPink"
app:dotPaddingBottom="1"
app:dotPaddingLeft="1"
app:dotPaddingRight="1"
app:dotPaddingTop="1"
app:dotRadius="4"
app:dotSpacing="2"
app:format="0 0 : 0 0 : 0 0"
app:transitionDuration="300"
app:valueUpdater="clock_per_second" />
