Hello,
I am trying to create my own keyboard because I need it in one of my
application. The problem is when I can seem to get the KeyboardView to
get displayed without an exception.
I tried two ways:
1.
- I had the KeyboardView in my main.xml layout file:
...
<LinearLayout ...
...
<android.inputmethodservice.KeyboardView
android:id="@+id/keyboard"
android:layout_width="120dip"
android:layout_height="120dip"
android:keyTextSize="10px"
android:labelTextSize="10px"
android:keyBackground="@drawable/icon"
android:popupLayout="@+layout/keyboard"
/>
...
- in the layout folder I wrote the keyboard layout file:
<?xml version="1.0" encoding="UTF-8"?>
<Keyboard
xmlns:android="http://schemas.android.com/
apk/res/android"
android:id="@+id/mykeyboard"
android:keyWidth="50px"
android:keyHeight="50px"
android:horizontalGap="2px"
android:verticalGap="2px" >
<Row android:keyWidth="32px" >
<Key
android:keyLabel="A" />
</Row>
</Keyboard>
- in onCreate I had:
setContentView(R.layout.main);
2.
- I commented the keyboardview from main.xml , got the LinearLayout
object from main.xml and tryed to add KeyboardView from code:
myLayout.addView(new KeyboardView(getApplicationContext
(), null));
In any case I got the same IllegalArgumentException. I think somehow
the KeyboardView tries to grab more pixels than it got. (
