Ararat

Ararat is a crossword library for Android, written for and used by alphacross. It includes:

• Parsers for various formats
• CrosswordRenderer, which can render a crossword (and optionally, current state) to a Canvas
• CrosswordView, the View subclass that handles gameplay

For a demonstration, see the included demo app.

The sample crossword included in the app is Double-A's by Ben Tausig.

Quick Start

Add dependency to app/build.gradle (check to make sure you're using the latest version):

dependencies {
    implementation 'com.github.0xe1f:ararat:1.0.15'
}

Add view to your layout:

<org.akop.ararat.view.CrosswordView
    android:id="@+id/crossword"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Initialize the view in OnCreate():

val crosswordView = findViewById<CrosswordView>(R.id.crossword)
crosswordView.crossword = readPuzzle()

Existing puzzles are usually read from a stream, e.g.:

fun readPuzzle(): Crossword = resources.openRawResource(R.raw.puzzle).use { s ->
    buildCrossword { PuzFormatter().read(this, s) }
}

For the activity to respond to soft keyboard changes, set android:windowSoftInputMode to adjustResize in the manifest:

<activity android:name=".MainActivity"
          android:windowSoftInputMode="adjustResize" />

Keyboard Support

CrosswordView was designed to work with the Android soft keyboard. Unfortunately, with the exception of maybe Google and the AOSP codebase, virtually no one follows the rules of Android IME, including many third-party manufacturers and authors of soft keyboards. They will often mistakenly assume that any view has full support of things like autocorrect and swiping - concepts that don't work in the limited scope of input needed for crosswords, and will ignore any attempts to disable those features.

If you're serious about your own crossword app, your best long term bet is to use your own KeyboardView and have it provide the input instead.
