dispatchKeyEvent
takes in a KeyEvent object as parameter. And
From Android documentation:
Note: When handling keyboard events with the KeyEvent class and
related APIs, you should expect that such keyboard events come only
from a hardware keyboard. You should never rely on receiving key
events for any key on a soft input method (an on-screen keyboard).
Also from here:
As soft input methods can use multiple and inventive ways of inputting
text, there is no guarantee that any key press on a soft keyboard will
generate a key event: this is left to the IME's discretion, and in
fact sending such events is discouraged. You should never rely on
receiving KeyEvents for any key on a soft input method. In particular,
the default software keyboard will never send any key event to any
application targetting Jelly Bean or later, and will only send events
for some presses of the delete and return keys to applications
targetting Ice Cream Sandwich or earlier.
In order to dispatch key events from an on-screen keyboard you, have to add textWatcher to your editText.
For example:
myEditText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void afterTextChanged(Editable editable) {
}
});
