I use custom xml attributes for preferences. The preferences are inflated from xml.I managed to create and read custom xml attributes for EditTextPreference, ListPreference and CheckBoxPreference by creating custom classes which inherit from the respective preference class.My problem is that I can't do this for the PreferenceScreen class, as it is a final class. So my question is: Is there any way I can read the custom attributes of a PreferenceScreen?

I have defined custom views in the various layout .xml files. However, all the layouts are using the Linear Layout - put the content would vary.
I would like to create my own widget tag something like <com.mypackage.MyLinearLayout />, I would like to pass the layout as a param to the <com.mypackage.MyLinearLayout layout="@layout/simple.xml" />
How to define new attributes to the custom widgets ? Simply defining a getter/setter method would work or is there any other references.
I have seen examples implementing a custom Filter. The Android developer docs talk about implementing a Filterable interface. Does anyone have any advice and/or sample code on the best way to implement filtering in a ListView ?
View 2 Replies View RelatedI am trying to get the images to have transparent backgrounds so the map is not blocked by a square marker with an image in it. What image editor and what settings should I use to get this to work?
I am trying to do some custom backgrounds for buttons and the same problem comes up: I get square corners and a background that does not scale with the buttons.
I think this all part of the same problem: I am not using the right tool with the right settings to create the images. I must be misinterpreting the documentation and examples that talk about a white border around the image and a black line along the top and left side for the expandable button background.
Here's a quick way to reproduce the problem:
Follow the directions to create the MapView program as described on:
http://developer.android.com/resources/tutorials/views/hello-mapview.html
For the icon I first used the image copied from the page:
Next I edited the picture in Microsoft Paint, and cut off the little guy's antennae. I'm not cruel and no real androids were harmed in that experiment. I surrounded the new picture with a pixel thick border of white, copied from the border that was around the rest of the image, and then copied the black that was there as well in the void areas of the image, outside the border.
I saved the image as myandroid.png and copied the file to the layout folder. Pointed the activity to the new pic and ran the program.
The image was displayed with a full square background and shadow, not the android shaped image and shadow that was there when the original image was used.
Custom Button background:
Follow the directions for the Relative Layout example at:
[url]
Next, I created an image to expand as a background for the button called backbutton.png. It too is surrounded by a white border and black filled on the corners, the top and one side per documentation I found in "Android Programming Tutorials" on page 298.
The background does not expand, nor do the corners round.
I wish I could show you screenies of what I have.
How do you create the images for the custom backgrounds and the images for the custom map markers and buttons? I need to know what image editor to use and the file attributes to set, so the images expand and display with the proper void spaces in them.
I just went through the process of compiling a custom ROM and they used a stock kernel. I would like to incorporate a different kernel when I compile and instead of the stock. I know I could compile them separately and have them flash together but I want one zip to flash. Just would like to go through the process to learn.
what I have to do when compiling?'
I try to implement a custom button(OnPressButton), and the code is in below. In LogCat, I can see the two parameters (btn_up/btn_down) value are below:
btn_up=@drawable/btn_up btn_down=@drawable/btn_up
But how can I convert this to point to R.drowable.btn_up and R.drowable.btn_down ?

I'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but
code:...................
The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.
So what is the proper way to set a custom attribute in a style?
My application has a setting menu which is actually a PreferenceActivity.When it's created, if a boolean value is not set I want to go to the DialogPreference which sets that.How should I do this? It's ok to add that DialogPreference to the manifest?
View 2 Replies View RelatedI have a DialogPreference in my Preference Activity and would like to know which button was pressed. I have implemented the OnSharedPreferenceChangeListener which does not seem to get triggered when the DialogPreference is selected. I have also tried OnPreferenceClickListener but this gets triggered as soon as the DialogPreference is clicked from the main screen and not when one of the actual dialog buttons was pressed. I think I need to implement onClick for this dialog but I am not sure where to do this. I have looked at the API Demo code and it shows how to create the dialog but not how to determine which button was pressed.
public class Preferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {
private static final String LOG = "test"; private DialogPreference mfactory;
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ....................
I'm currently writing a live wallpaper for Android and it has a PreferenceScreen which currently contains only one preference - a DialogPreference to set various properties of animation.I'm looking for a way to skip showing that preferences list with only one item and to show that dialog right away.But it seems that PreferenceActivity requests itself to have PreferenceScreen as a root element of preference hierarchy. So is it even possible to do what i want?

View 3 Replies View RelatedThe default drop down view of the spinner occupies the entire width of the screen. I tried to create a custom spinner which occupies only some portion of the width of the screen, but I'm unable to do. I want to see the objects behind the drop down. Here is what i tried, I changed the drop down view as,
adapter.setDropDownViewResource(R.layout.simple_spinner_dropdown_item); instead of
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
In the layout.simple_spinner_dropdown_item.xml file I specified the width, but it still occupies the entire width. Can any one help. Is there any other view which is similar to spinner but I should be able to see the background objects like a alert dialog. Is it really possible?

I've googled a little bit and I cannot come up with a document that shows what the android file system even is. (I'm sure it's out there).

View 3 Replies View RelatedI'm writing my own custom view, a keyboard, which I think the ArrayList in the keyboard view is causing the application to quit in the emulator.

I was trying to serialize an ArrayList which contains custom objects. I'm serializing it in a Servlet (server side), and deserialize at the client side. (using ObjectOutputStream and ObjectInputStream)
It worked fine, when I work with ArrayList<String>.
But when I tried it with ArrayList<MyObject> I couldn't get any results in the client side, this is the exception:
java.lang.ClassNotFoundException: web.MyObject
Of course I have done this:
public class MyObject implements Serializable { ... }
MyObject contains only String fields.
