Re: onTouchEvent triggered three times when I click on the screen only once

Down, move, up.  Look at the action code in the event to see which of
these actions is happening.

Re: onTouchEvent triggered three times when I click on the screen only once

It works. I just need to check if it is DOWN action and ignore other
actions. I thought DOWN action meant moving down, but actually it is
like onKeyDown. Thanks!

I am just curious why the API doesn't uniform event model. Like
onKeyDown and onKeyUp, why not provide onTouchDownEvent,
onTouchMoveEvent, and onTouchUpEvent?

Re: Question About AndroidManifest.xml and resources

Hi

1. Basically the error mean I did not declare activity in manifest
where generate this error when I start activity... What I intent to do
is to start activity without declare it at manifest... How can I hard
code those manifest info inside my code to start an activity?

2. 2nd problem is my ApplicationContext.java in android.jar say got
nullpointer error at line 291... How can I know what the error
about??? How can solve it with those little info???

my objective is to start an activity(this activity will not declare it
at manifest) dynamically... Set the new Resources for the activity...
Any one know??? Please guide me some way...

wesley.
