For example if I have a main app and three modules in mind, such as: audio, video, and calendar (The modules itself does nothing. They're useful only when called by the main app) 1. how will the main app know that those modules are installed on the phone, and can call them? how do I get a list of modules (mine) ? 2. also how do I make my modules hidden to user, they should not be visible for launch, and should not be able to launched by an icon, only by my app? 2009/11/8 RichardC richard.crit...@googlemail.com Read all about Intents.

[android-beginners] Re: Suggestions on tutorials
This returns to the argument that always comes up in programming.is A better than B or B better than A. In this case XML has some advantages but of course sometimes you need to do things through code. I would review your approach and think maybe i should take off my blinkers and look at XML (as making an XML menu layout takes seconds in Android once you have done one you have done them all), maybe you won't use XML 80-90% of the time but for simple menus and things like that writing code to do it is much more time consuming and error prone, especially as the Eclipse enviroment and Android plugins really aid the development. As a side note about the magic of XML allowing you to redesign an app without coding. If you change your ui there is a 99% chance you are changing some logic behind the scenes as well. But now you have XML to change and make sure the R.class gets gened and that you used the write keyword from the R.class in your code. You see you have increased the likelihood of an error 3x. you say this - but with the Android Development tools this isn't an issue that i have seen. The XML in android is not read in at runtime like a CSS might be in HTML but is used to build java classfiles. And as far as I have seen the XML does not link data in from a model to fields. So really all the XML can do is provide some format and ordering support. Seems like a lot of effort and points of failure for such little return. this is a classic argument - but as an older programmer with C/C++ background and Java background for embedded devices, i could state that Java is slow/with bad memory management and we should be using C/C ++ to develop, but sometimes it is just quicker to use Java! which is the basic argument for using XML Regards, David On Nov 8, 6:43 am, sfitzjava sfitzj...@gmail.com wrote: Hmmm.

[android-beginners] Re: How to build EditText view like that in Android Market where X button appears for clearing text?
I've just been playing around with this solution and it works, sort
of, but feels a little hacky.
I was wondering if this alternative might work:
1. Use a LinearLayout and set the background to be the same
StateListDrawable used by EditText - I can't get this to work, but
then again I'm a newbie when it comes to StateListDrawables.
2. Add an EditText as the first child of the LinearLayout. Set the
background of the EditText to transparent.
3. Add an ImageView as the second child of the LinearLayout. Set the
src to be the X drawable.
This has the advantage of not having views on top of each other (where
one provides the image, and the other listens for the events).
Also, if, for example, the text is empty, then we can set the
visibility of the ImageView to GONE, so that the cross is no longer
visible AND the hint text has more space.
If this is a sensible approach, would appreciate some pointers on how
to configure the LinearLayout so its behaves like an EditText...

To answer my own question...
Use TextView.setCompoundDrawables(null, null, null, null) to hide the
cross.
Next thing is to detect when the cross is pressed on.
Currently I do this:
mEditText.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if (mEditText.getCompoundDrawables()[2] == null) {
// cross is not being shown so no need to handle
return false;
}
if (event.getAction() != MotionEvent.ACTION_DOWN) {
// only respond to the down type
return false;
}
if (event.getX() mEditText.getMeasuredWidth() -
mEditText.getPaddingRight() - x.getIntrinsicWidth()) {
mEditText.setText();
return true;
}
else {
return false;
}
}
});
This works but feels rather messy to me. Also, I'm not sure about the
mEditText.getPaddingRight()...
Is there a better way?
Possibly, now that you sent the screenshot (thanks!). BTW, what you are
seeing may be part of the HTC Sense UI -- it's certainly not what you
get in ordinary Android.
Regardless, here is how I would proceed to try to get this to work:
Step #1: Keep your current Drawable code, but replace your X with a 100%
transparent image of the same size. There might be a better way to
accomplish this step, but I can't think of one off the top of my head.
Basically, I am guessing that if you type a lot into that field on your
Hero, the text does not wind up under the X, so you need a placeholder
to keep the text to the left.
Step #2: Wrap your EditText in a RelativeLayout. Put whatever layout
rules you presently have on the EditText (layout_width, etc.) on the
RelativeLayout, and set the EditText to be fill_parent/fill_parent for
width/height.
Step #3: In the same RelativeLayout, *after* the EditText in the XML,
add an ImageView with your X, with layout_alignParentLeft=true and
enough paddingRight to have it positioned properly. RelativeLayout, like
FrameLayout, supports vertically stacking widgets, so by having your
ImageView be after the EditText in the XML, it will float over the
EditText and be visible/touchable.
Step #4: Add an OnTouchListener to the ImageView in your code.
A variation on this approach would be to use the X image in Step #1 and
a transparent View in Step #3. This is the old hot-spot trick from a
byegone programming era -- a background provides the image and you have
something floating over top where things are touchable. If you specify a
View with background=#, it should be invisible, and if you
size/position it properly, it will sit over top your X. It's a bit more
difficult to debug, though you could temporarily use a translucent
background (say, #22FF for a slight red effect) until you get the
hot-spot positioned properly.
These approaches have the advantage of avoiding the OnTouchListener
calculations you are doing in the EditText, which might have problems if
EditText changes behavior in future releases. On the other hand, these
approaches add a few more widgets and therefore take up a bit more memory.
If the X appears to actually click when tapped on your Hero, then they
may be using an ImageButton with a custom set of backgrounds rather than
an ImageView. That is also possible to implement independently but gets
decidedly more painful.
Once I get my hands on an HTC Sense-ible device, I may try to cook up
some canned widgets to offer some of their looks, like this one, in
plug-and-play form.
A question for you: does this X effect show up in places other than
the Android Market search app on your Hero? Thanks!
