[android-beginners] How to get direction in my android app
Hi, I'm a beginner in Android and I would like to know if it is possible to use an API for direction getting. Is there a fonction witch permit, as Google Maps for example, to define a path (intermediary points) with a start and a end points ? I would like to do this on android platform and my research shows me that it seems not possible... thank you for your help and please excuse my english ! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] HELP! R.layout.main cannot be resolved error
Hey all,
I have been fiddling around with Android for the past couple of days,
and I was working through the tutorials and sample code. Yesterday, I
made an interface with DroidDraw, which generates XML to make the GUI.
As far as I can see, everything is in order, but I have an error when
it goes to pull the XML from the layout folder. It says that
R.layout.main cannot be resolved, and thus all subsequent links to the
XML get a similar error. I have been plugging away on this problem for
a couple of hours, but cannot get it to work. I checked the forums
already, and someone mentioned that the version of DroidDraw may not
be compatible with the new SDK, but I checked what was posted, and it
seemed to work fine. Below is the JAVA code, and then the XML from
Droid Draw.. any help would be appreciated!!!
Thanks!

[android-beginners] Re: HELP! R.layout.main cannot be resolved error
Hi,
It seems that res filename must contain only [a-z0-9_-.]. (It is
possibly undocumented issue.)
Change your layout filename from DroidDraw.xml to droiddraw.xml or
simply main.xml, and hand same name to setContentView().

Thank for the info Tatsu... The file I am trying to import is
main.xml, and is located in Res-Layout. I just labeled the XML
DroidDraw to pretty much say it was from DroidDraw.. I wasn't awake
yet when I put that in there I guess, lol.
I am not quite following the part about the res filename. Pardon my
ignorance, I have only been doing JAVA stuff for a few days, and I am
not very well versed in it. Would you be able to be a little more
detailed with that explanation?

[android-beginners] Re: HELP! R.layout.main cannot be resolved error
Well, the resource stuff isn't a Java thing, it's an Android thing.
Basically if you put a layout xml file in res/layout, you reference it
by filename when you call setContentView. For instance, if you have
res/layout/my_fancy_layout.xml, you make a call to
setContentView(R.layout.my_fancy_layout).
But, it sounds like you have a main.xml in that directory and using it
correctly with setContentView. The layout xml looks valid for the m5
sdk. Are you using m5 or m3? Also, if you are using eclipse, it should
tell you if theres a problem in the xml file itself when you open the
file. That might give some insight.

[android-beginners] EditText getText() to string for notification
Hi, I have my application set to grab the text from an EditText field,
but for some reason even if I convert it toString, the returned
string always comes back blank. Here is my code:
Button button;
EditText text;
button = (Button) findViewById(R.id.btnOK);
text = (EditText) findViewById(R.id.txtCustomerName);
final String message = text.getText().toString();
button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Toast.makeText(HelloWorld.this, message,
Toast.LENGTH_SHORT).show();
}
});
Sorry for the bad code organization, but copy and paste didn't really
work out the way I imagined, Haha. Any help would be great. Also, I
tried searching, but for some reason I just can't find a solution.

[android-beginners] Re: EditText getText() to string for notification
Because message is whatever text is in the EditText whenever this
bit of code runs. I assume this is ran in onCreate? Probably this is
blank unless you gave it a default value. What you might try is to
remove the message variable and then call text.getText().toString() in
the Toast.makeText method.
