[android-beginners] Re: The notepad tutorial

[NeeravA]

The tutorial does not exactly say why it crashes on hitting the back
button. The crash happens in part2.

the link for part3 is as follows.
http://developer.android.com/resources/tutorials/notepad/notepad-ex3.html

check out step 1.

 i see this stack trace.
java.lang.RuntimeException: Failure delivering result
ResultInfo{who=null, request=1, result=0, data=null} to activity

A MapView is a ViewGroup like any other -  you can add other views to it at
any point. Unique to MapView are layout params that let you place views
based on map coordinates.

It's a simple matter of defining the layout you want to show, inflating it
on tap, and adding it to the MapView at the correct location.

Re: [android-beginners] Advice For First (Simple?) Non-Tutorial Project

[Daniel Favela]

Greetings again, fellow beginners!

I looked through status.net and it provoked a question.  I do not need
something too specialized; in fact, I don't really have the server to host
the suggested microblogging service on.  Instead, does Android have the
capability to do something with a public medium instead, as described below?

--- Affecting the Counter ---
1. User makes a selection to add or remove themself to/from the counter.
2. The app posts something to a public medium (example: twitter) account
that indicates an addition or a removal.
3. The app updates its counter according to the user's addition/subtraction.
4. The app looks up the public counter (below).

--- Looking Up the Counter ---
1. The app looks up the "twitter" account.  For simplicity, let us say that
this occurs when a user adds or removes themselves (above).
2. The app reads entries from some date/time to present date/time; entries
contain text that indicate additions/subtractions to the count.
3. The app reads/parses these entries.
4. The app updates its counter according to the entries' values.

What I want to know: is all that possible on the Android?  You don't have to
give me details if you don't feel like it, but any
direction/comments/ideas/pitfalls are welcome.

Thank you for reading, and have a great day!

-Danny

Re: [android-beginners] ubuntu 10.04 emulator not launching

[David Turner]

can you start the emulator from the command line properly (e.g. :
$ANDROID_SDK_ROOT/tools/emulator -avd )

Can you try with the -verbose option to see if it dumps useful information,
there is also -debug-all which is going to dump a *lot* of stuff.

It looks like the emulator has problems connecting to your X server. How is
your DISPLAY environment variable defined ?

[android-beginners] Question on finishOnTaskLaunch

[Ubuntu Explorer]

Hi,
I read the following text in App. Fundamentals today.

This attribute is like clearTaskOnLaunch, but it operates on a single
activity, not an entire task. And it can cause any activity to go away,
including the root activity. When it's set to "true", the activity remains
part of the task only for the current session. If the user leaves and then
returns to the task, it no longer is present.

Does this mean, all activities with this flag set, will do away when the
user moves out of and then back in to the task. Doesn't this leave the task
with a different set of activities? For ex, before leaving task has A-B-C-D,
where B and D are set to clearTaskOnLaunch. After moving out of task, user
comes back to task. He will see - A-C. Am I right ?

Is there a use case for this behaviour?

Regards,
UE.

[android-beginners] Re: set clip in canvas

[jasont]

Canvas has several clipRect methods,
http://developer.android.com/intl/fr/reference/android/graphics/Canvas.html#clipRect%28float,%20float,%20float,%20float,%20android.graphics.Region.Op%29

Here is a more through explanation since you mentioned J2ME:
http://jtomlinson.blogspot.com/2008/10/clipping.html The main key is
passing in Region.Op.REPLACE

Re: [android-beginners] Human interface guidelines. Equivalent to iPhone sectioned table

[Kostya Vasilyev]

The Android Dev Guide does exist:

http://developer.android.com/guide/practices/ui_guidelines/index.html

It covers in detail how application is supposed to guide the user from one  
activity to another.


However, it does not specifically cover your question.

Perhaps you could use a list view, make it look like Android's built-in  
preference screens, with two-line items, each containing the name of  
action to be taken and its description in smaller text below.


By adding nice graphics in the top portion of the view, and using a theme  
to set colors to something nice (other than the default white-on-black), I  
think can be made look quite good.

What is the suggested equivalent on Android? Do any UI guidelines

iPhone version has an image background surrounding the table.

Some options I can think of include:
- A series of buttons: Not sure if this will look cheesy.
- A list view: Typically consumes the whole window. Doesn't look as
nice as the iPhone version.
- A list view inset in a window: I've done this before. Looks ok.
Corners are not rounded like they are on the iPhone. Can do a
background.

Any suggestions?

No it won't! The error is not about downloading the file but about
validating the XML *once it's downloaded*.

[android-beginners] EditText Image changing look when given at runtime.

[Alok Kulkarni]

Hi guys,
I am having an EditText. If i specify image for the EditText in the layout
XML file (android:background) it looks different and looks different when i
specify it at runtime
EditText et = (EditText)findViewById(R.drawable.et1);
et.setBackgroundDrawable(Main.themes.getDrawable(EDRAWABLES.EditTextBackgroundImage));
Both codes point to the same image. When i specify the image at runtime ,
the EditText leaves a margin at the top and bottom of the cursor in the
edittext which does not happen when i do it in XML.
I have attached the screenshots of both images. Top image is the one drawn
from XML and bottom one is given at runtime.
I am not getting the difference ?
Actually i am facing similar problems with other Widgets too if i change the
logic of specifying the drawable at runtime and not at compile time..
Is this the default SDK behaviour ?
Thanks,
Alok

If I remember correctly, doesn't that tutorial have more parts to it that

Not without more information. Have you run the tutorial? Does it crash as it
says? What's the stack trace at that point?

[android-beginners] set clip in canvas

[pti4ik]

Hello everybody! Can anyone tell me if there is a way to set a clip in
my Canvas to the specific rectangle, equivalent to setClip(x, y,
width, height) from class Graphics in J2ME?
I found only the ways to intersect my clip with a rectangle or region,
but not to move it to the specific position and size.

Best regards, Andrew

[android-beginners] Adding an HTML content to a webview without space

[And-Rider]

I am trying to add an HTML content to a web view. If the words in the
HTML content are without spaces then webview keeps that particular
word on the same line.I want that content to be wrapped and be on the
next line.Is it possible to do that.I am attaching a sample code that
can reproduce the issue.

[android-beginners] Problem with StateListDrawables not found in 1.5 but there from 1.6 onwards

[Alok Kulkarni]

Hi ,
I am having the following code for drawing buttons in my project.
I am having a button which has three images for 1 button .Namely one image
for the rectangle and 2 images for the left and right side curves
respectively.
When the button has focus , there is another three images for focus and
similarly 3 images when button is pressed.
Following is the code.

public void setButtonStyle(Button btn) {

//The middle rectangle
StateListDrawable drawables = new StateListDrawable();
drawables.addState(new int[] { stateFocused, -statePressed },
dButtonMidOverImage);
drawables.addState(new int[] { stateFocused, statePressed },
dButtonMidDownImage);
drawables.addState(new int[] { -stateFocused, statePressed },
dButtonMidDownImage);
drawables.addState(new int[] { -stateChecked }, dButtonMidUpImage);

btn.setBackgroundDrawable(drawables);

//The left curve
StateListDrawable drawablesLeft = new StateListDrawable();
drawablesLeft.addState(new int[] { stateFocused, -statePressed },
dButtonLeftOverImage);
drawablesLeft.addState(new int[] { stateFocused, statePressed },
dButtonLeftDownImage);
drawablesLeft.addState(new int[] { -stateFocused, statePressed },
dButtonLeftDownImage);
drawablesLeft.addState(new int[] { -stateChecked },
dButtonLeftUpImage);

StateListDrawable drawablesRight = new StateListDrawable();
drawablesRight.addState(new int[] { stateFocused, -statePressed },
dButtonRightOverImage);

//The right curve
drawablesRight.addState(new int[] { stateFocused, statePressed },
dButtonRightDownImage);
drawablesRight.addState(new int[] { -stateFocused, statePressed },
dButtonRightDownImage);
drawablesRight.addState(new int[] { -stateChecked },
dButtonRightUpImage);

//Compound drawables set for left and right side.
btn.setCompoundDrawablesWithIntrinsicBounds(drawablesLeft, null,
drawablesRight, null);


}
This thing which i have done runtime can be done in the XML too , but i want
to change themes runtime so my images for button will also change runtime.
If i do the code in the XML it works fine on both Android 1.5 as well as
Android 1.6 .But doing it in code distorts the images for 1.6 emulator.
I have attached the screen shot of the buttons on both 1.5 and 1.6
emulators.As you can see, the left and right curve images come almost to the
center and the centre image is expanded in 1.6 emulator. The same problem is
seen on HTC Desire (Android2.1)
Is there something wrong that i am doing . Is there any workaround for this
problem.
Thanks ,
Alok.,
