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 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'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?

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?

View 5 Replies View RelatedI've got a custom xml file in my res/xml folder, and it's not an android xml file (in that it doesn't describe a button or set of views or anything, just data for my app) and now I want to read it with an XML Pull Parser, but I don't know where to find it on the android file system. 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.
public static ArrayList<HexButton> hexButtons = new ArrayList<HexButton>();

But I want to nest my keyboard with a TextView so I'd like to be able to do
setContentView(R.layout.main);
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.

View 2 Replies View RelatedI'm trying to make a custom dialog to show a view in this dialog. This is the Builder code:
//Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_dialog_simple,(ViewGroup) findViewById(R.id.rlDialogSimple));
//Change Text and on click
TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple);
tvDialogSimple.setText(R.string.avisoComprobar);
Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple);
btDialogSimple.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//Do some stuff
//Here I want to close the dialog
} } );
AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this);
builder.setView(layout);
AlertDialog alert = builder.create();
alert.show();
So, I want to dismiss the dialog in the onClick of btDialogSimple. How I can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so I don't want to make a builder.setPositiveButton.
I'm getting a NullPointerException while attempting to create a Spinner within a dialog and can't seem to debug it because the code looks solid. Wonder if anyone else has any idea. Any help is greatly appreciated.
protected Dialog onCreateDialog(int id) { Dialog dialog;
switch(id) { case DIALOG_SEND_PM: Spinner spinner = (Spinner)findViewById(R.id.pm_server);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.server_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
dialog = new Dialog(PM.this);
dialog.setContentView(R.layout.send_pm_dialog);
dialog.setTitle(R.string.send_pm);
pmMessage = (EditText) dialog.findViewById(R.id.send_pm_box);
Button sendPm = (Button) dialog.findViewById(R.id.send_pm_button);
sendPm.setOnClickListener(PM.this);
break;
default: dialog = null;
}
I get the exception at adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
I changed the context to MyClass.this and the exception moved down to the next line, which confuses me. I'm wondering if it is the adapter having a null value but I call everything the same way I have before while not in a dialog.
Relevant XML data:
<LinearLayout> <TextView/> <LinearLayout> <TextView/>
<EditText/> <TextView/> <Spinner
android:id="@+id/pm_server"
android:layout_height="fill_parent"
android:layout_width="wrap_content"

</LinearLayout> <Button/> </LinearLayout>
This seems like an obvious thing, but I can't find any way to do it.When I put my phone in the car dock, instead of auto-launching the official "car dock" application, I want to launch an app of my own choosing. (in this case vlingo)I can find various apps that specifically replace the car dock app, but that's not what I want, I want to use vlingo (which doesn't seem to have that option by default)Just to be clear, I don't want an app that gives me an icon I can click to launch vlingo, that would defeat the purpose as I can already click the icon on my home screen to launch it if I want.So how can I set what program launches when I drop it in the car dock?
