From b38070caa5143ab9fd1883e0c7c879533a480bc7 Mon Sep 17 00:00:00 2001 From: Victoria Lease Date: Fri, 24 Aug 2012 13:46:02 -0700 Subject: IME support for trackball and generic motion events Trackball and generic motion events now pass through the IME in case it would like to handle them before passing them on to the view hierarchy. While I was at it, I also... ...fixed the documentation on InputMethodService.onKeyUp() ...added documentation to InputMethodService.onTrackballEvent() ...added trackball and generic motion events to the "input" command ...fixed input consistency verification involving ACTION_OUTSIDE Bug: 7050005 Change-Id: I40ab68df4a9542af6df25de6ec2ec500e4c02902 --- .../src/com/android/commands/input/Input.java | 106 +++++++++++++++++---- 1 file changed, 89 insertions(+), 17 deletions(-) (limited to 'cmds/input') diff --git a/cmds/input/src/com/android/commands/input/Input.java b/cmds/input/src/com/android/commands/input/Input.java index 341f30f..a21df0d 100755 --- a/cmds/input/src/com/android/commands/input/Input.java +++ b/cmds/input/src/com/android/commands/input/Input.java @@ -66,15 +66,54 @@ public class Input { } } else if (command.equals("tap")) { if (args.length == 3) { - sendTap(Float.parseFloat(args[1]), Float.parseFloat(args[2]));
