[android-beginners] Newbie to Java needing some help!
My code is quite simple. When the gunbutton is pressed it should check
that there are bullets left. If so, it should check wether the
silencer is on or off, if its off it should bang and if its on it
should be a quiet bang. If there are no bulelts left it should make a
ammo_out noise.
It counts ammo correctly but the silencer is always on, despite me
declaring it as off. Please help!

Your problem is a classic one in Java, on this line:
if (silenceron = true) /** If the Silencer is on this
...you are effectively testing whether you can assign the boolean
value true to silenceon, which you always can (hence it's always
true). Add another equals to test whether sileneron is equal to true.

Not a problem. If you are new to Java and eclipse, I would suggest you use eclipse debugger which will step through your code and you can see what the value of the variable is at every step of the code. That way you'd notice the variable value change right after the 'if' statement. On Sun, Aug 9, 2009 at 9:02 AM, Hugh lordhornb...@googlemail.com wrote: Damn, now i feel stupid.

If the third-party library needs classes in java.beans that are not in Android, it will not work without modification.

Stefan wrote: i have a problem with the TableLayout. I want to put 4 buttons in one TableRow and i set the size. But the size of the first button is equal to the size of a TextView in an other TableRow. Why?? TableLayout works like HTML tables -- the column widths are set by their contents. The width of your first column will be the maximum width among all of the first items in each row. The first item in your first row is the TextView, and the first item in the second row is the first Button. Whichever of those is wider (presumably the TextView) will determine the width of the column. Moreover: The children of a TableRow do not need to specify the layout_width and layout_height attributes in the XML file. TableRow always enforces those values to be respectively FILL_PARENT and WRAP_CONTENT. (from http://developer.android.com/reference/android/widget/TableRow.html) Hence, the smaller widgets in the column will expand to fill the space set aside by the largest widget. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coder's Guide to *Advanced* Android Development_ Version 1.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

Hi. I was following this tutorial: http://mobiforge.com/developing/story/using-google-maps-android on creating map activities, Now i am unable to understand why my application crashes. I get a NoClassDefFoundError and that exception is caused by a Caused by: java.lang.IllegalAccessError: cross-loader access from pre-verified class. Now i have added the uses-library android:name=com.google.android.maps / as a child element to my aplication and uses-permission android:name=android.permission.ACCESS_FINE_LOCATION/uses- permission and uses-permission android:name=android.permission.INTERNET/ as children of the Manifest element. My avd is running on api level 4 with the google apis. What is wrong? i have searched the web, but nnot found a solution to my problem. Appreciate any thoughts or comments on what might be wrong --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: TableLayout problem
Hi, i take a look in your, Mark M., book (Busy coders guide to android development 2nd version) and I try to change your RelativeLayout example in my own xml layout file. But all widgets (Buttons, TextView, EditText) are in one row and they lie on top of each other. I have not much experience with the layout files, but i think their can not be very much wrong??

But all widgets (Buttons, TextView, EditText) are in one row and they lie on top of each other. They don't for me. Here is your file, as rendered in Android 1.5r3: http://imagebin.ca/view/a9G9zjd0.html Whether or not this look is what you want is another matter, but the widgets are not in one row. Some are pushed off the screen, but that is what you told the RelativeLayout to do. For example: TextView android:id=@+id/ak android:text=aktuelle km: android:layout_width=wrap_content android:layout_height=wrap_content android:layout_below=@id/epe android:layout_alignRight=@id/epe/ Your android:layout_alignRight=@id/epe attribute means you want the *right edge* of @id/ak to align with the *right edge* of @id/epe. That, in itself, is not necessarily strange. Since @id/epe is set to fill_parent, it's right edge is the right edge of the screen, and so the right edge of @id/ak is set to the right edge of the screen. But then, your next widget has: EditText android:id=@+id/ake android:layout_width=fill_parent android:layout_height=wrap_content android:layout_toRightOf=@id/ak android:layout_alignBaseline=@id/ak android:text=0/ Here, you are trying to put @id/ake to right of @id/ak, which will not work well, since your previous rule set @id/ak to have its right edge on the right edge of the screen. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, $35/Year --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: TableLayout problem
thanks for the fast answer again. i work with the 1.5r3 version, too. but in eclipse, if i switch in the Layout tab, all widget are in one row. i don't test it, if I run an app with this layout. Now I have another view in the DroidDraw application. Thats view has more to do with my xml file. Now I will continue work with this tool to correct the mistakes.

[android-beginners] GestureListener events
i'm using the GestureDetector and GestureListener in a program. i want
to have separate actions for the onFling and onScroll events. for a
scroll event there is no problem - only the onScroll event is
called. however for a fling event BOTH the onFling and onScroll
events are being called. i tried returning true in the onFling
method to prevent further propagation of the event but that didnt
help. following is the code excerpt from the onTouchEvent and the
related gesture events:
private static boolean fling, scroll; //two boolean values to detect
whether the performed action is a fling or scroll
private GestureDetector scanner; //this is the gesture detector
public boolean onTouchEvent(MotionEvent me){
fling = false;
scroll = false;
scanner.onTouchEvent(me);
if (fling) {
scroll = false;
return true;
} else if (scroll){
return true;
}
return super.onTouchEvent(me);
}
public boolean onFling(MotionEvent e1, MotionEvent e2, float
velocityX,
float velocityY) {
fling = true;
return false; //changing this to return true at this point
makes no
difference
}
public boolean onScroll(MotionEvent e1, MotionEvent e2, float
distanceX,
float distanceY) {
scroll = true;
return false;
}
what i tried in the onTouchEvent method above is to put a kind of a
lock so that if a fling is detected then the appropriate action is
taken and the event is not propagated further. however despite trying
every combination of returning true / false in each of the above
methods, i am unable to separate out the fling event from the
scroll event.
as i said - there is no problem in the conventional scroll - in this
case only the action for scroll is being performed.
for the gesture events, is there any particular sequence in which the
event is propagated? i.e. does it first go to the onClick, then the
onFling, then the onScroll ... etc?
any inputs will be greatly appreciated

[android-beginners] Need code sample for double lon= loc.getLongitude();
From GPS, I am trying to get latitude longitude, bearing and speed.
Just a one time snapshot.
My code is here:

The loc is always 0.
Q: Must I initialize the GPS provider somehow??
Any complete code snippet most welcomed...

You need to use the LocationManager:
lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
