Modifying the keyboard in Android



You can show and hide rows - kind of. You can't actually modify a keyboard after you've instantiated it with the new keyword. Instead, you can modify it at the time of instantiation:
 
new Keyboard(this, R.xml.keyboard_layout, R.integer.keyboard_show_extra_row)

I put the constant keyboard_show_extra_row in a file called keyboard.xml, but you can actually call that file anything as long as it's in the values folder:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <integer name="keyboard_show_extra_row">1</integer>
</resources>

and add the constant to the rows that you want controlled by this constant:

<Row android:keyboardMode="@integer/keyboard_suggestions">
    ...
</Row>

Then you just instantiate as described above.

Modifying after instantiating

Apparently you can't modify after instantiation. However, you can create two copies, one created with this flag and one without. You can then switch between them with the setKeyboard method.

Keyboard KeyboardView InputMethodService Input Connection Keyboard.Key (xml) Keyboard.Row (xml) Other documentation from Android A working code example direct from Android - very useful !  Android Developer tutorial - pretty much the same as all the others Android Developer blog - again, not much new here Stack Overflow Popup Keyboard - useful for special characters Custom Theme Showing and hiding rows (also see my post) Links to code repos AnySoftKeyboard GaroKeypad SquareKeyboard Blogs Chris Black - lots of good links Let me know if you find anything else that adds to som...

Settings in Android

I'm not going to teach you how to writing an activity for settings here - that's kind of obvious. Instead I'm going to highlight a couple of interesting things you can do with settings on an Android Keyboard. Opening your settings page We want to be able to open our settings page from two places. From the launcher. Add LAUNCHER to AndroidManifest.xml , like so: <activity android:name=".MainActivity">     <intent-filter>         <action android:name="android.intent.action.MAIN" />         <category android:name="android.intent.category.LAUNCHER" />     </intent-filter> </activity> <service     android:name=".MyInputMethodService"     android:label="Konjugator Keyboard"     android:permission="android.permission.BIND_INPUT_METHOD"     >     <meta-data android:name...
