Dear Tsukishiro,
Let me start with the bottom line which are
1. You need to have your own KeyboardView.
- Either extend from Android KeyboardView or make your own based
on Android KeyboardView.
- For example
http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.0.3_r1/android/inputmethodservice/KeyboardView.java#KeyboardView
2. Intercept GestureDetector.onTouchEvent(me) in the onTouchEvent()
- You need to grab the x, y of the ACTION_DOWN and identify which
key is actually pressed (before swiping)
3. Distinguish keyboard-level swipe and key-level swipe using your own
method
(Mine uses the swipe distance. Short = key-level, Long=keyboard-
level)
To actually implement your own view, you will need to tell the OS you
want to use your (keyboard) view instead
- Check out the method onCreateInputView()
- Don't forget to edit the xml/input.xml and change the class
name from Android KeyboardView to yours.
(Mine is
<com.solution9420.android.thaikeyboard9420.ThaiKeyboardViewNew
xmlns:android="http://schemas.android.com/apk/res/android";
android:id="@+id/keyboard"
android:layout_alignParentBottom="true"
....
....
I started by study the Android KeyboardView code.
In summary, there are two main portions
a. the drawing part - look into onDraw() but you can skip this part
for now.
b. Input capturing part
- the main logic is at onTouchEvent() and
GestureDetector.onTouchEvent(me)
- also this important one. detectAndSendKey()
Once you reach step #2, you can then start to dump out the x,y of the
actions you do on the keyboard.
Cheers,
Solution 9420
