Android IME intercept key takes precedence over view

In order to verify that an example was written

The first is the input method

public class Remotekeyboard extends Inputmethodservice  {  @Override public boolean onKeyDown (int keycode, KeyEvent event) {        if (Processkey (event, 0! = Event.getrepeatcount ()))            return true;        Return Super.onkeydown (KeyCode, event);    }    @Override public boolean onKeyUp (int keycode, keyevent event) {        if (Processkey (event, true))            return true;        Return Super.onkeyup (KeyCode, event);    }    Private Boolean Processkey (KeyEvent event, Boolean doIt) {         log.e ("=======", "============ Processkey"); return Fals e;}}

Next is the app view

    Final TextView Et1 = (TextView) Findviewbyid (R.ID.EDITTEXT1); Et1.setonkeylistener (new Onkeylistener () {        @Override Public        Boolean OnKey (View v, int keycode, keyevent event)        {        log.e ("====================", "====onkeylistener");        }

Run Program Print

============================: ============ Processkey

====================: ====onkeylistener

============================: ============ Processkey

====================: ====onkeylistener

The first time should be KeyDown, the second time should be KeyUp, indicating that the Android IME interception key takes precedence over the view

And experimented with rewriting system/usr/keychars/generic.kcm.

Change B to

Key B {
Base: ' B ' fallback dpad_center
}

In a non-editable box, log the following

12-23 05:18:09.093 118 118 E ============================: ============ processkey

12-23 05:18:09.094 118 118 E ============================: ============ processkey
12-23 05:18:09.163 118 118 E ============================: ============ processkey
12-23 05:18:09.163 118 118 E ============================: ============ processkey

Note B was not accepted and then called the Dpad_center

In an editable box, B is accepted, log is as follows

============================: ============ Processkey

============================: ============ Processkey

Description does not call fallback

If the modification is as follows

Key B {
Base:fallback Dpad_center
}

In an editable box also to play 4 lines of log, indicating that fallback was called
