I know that there are APIs for browser content providers to add bookmarks and add search strings to the db. But is there a way to access any of the options such as text size, default zoom, etc. I've looked at the source but can't seem to find a way, as the preferences file is private and there being no content providers for these settings.

I've prepared custom component based on LinearLayout. Whole component is defined in XML. Currently to use it you have to write:
<com.xxx.android.components.TopMenu
android:layout_width="fill_parent"
android:layout_height="44dp" />
Is it possible to set width and height in the java constructor? So it would be possible to write just:
<com.xxx.android.components.TopMenu />
I've tried to modify and set LayoutParams, but it didn't work for me.
I can't seem to find anywhere a way to programmatically change the the alignment of the button.
In the XML it is simply layout_gravity="Center" or something.
How do we do this in the code?
LayoutParams do not seem to cater for this.
If you use an AbsoluteLayout (I know that it is deprecated, but it was the only way to solve my problem ) you can give the childViews the tag "android:layout_x" and "android:layout_y" to set their absolute position within the AbsoluteLayout.
However I dont want to set these informationen in the xml, because I only know them at runtime. So how can I set these parameters at runtime programmatically? I dont see any method on the View like view.setLayoutX(int x) or something.
Here is my XML, which works fine, when I set the layout_x and layout_y values. code...
I would like change the width of a Horizontal Progressbar programmatically (initial size is set in XML using RelativeLayout...but I would like to dynamically change it based on certain values).
I have tried setMinimumWidth(50) in my code, but that did not make a difference. I have also tried setting 'android:layout_width="wrap_content", but that did not work either.
Here is my XML:

I'm unable to change the layout_gravity of a Button programmatically, does anybody know how to do this?The gravity attribute is easily changed using Button.gravity(), Ie it changes the gravity of the text inside the button I cannot change the gravity of the button itself. I also cannot seem to find this in any of the layout params contructors.

1. Time based (30 days etc)
2. Usage based ( 100 invocations of the application).

Is this possible? I have a free and a paid version of an application. From the FREE version I want to provide the ability to for the user to "PURCHASE" the paid version. I want to make it as simple as possible. I am thinking of Starting the market app and passing the identification of the PAID so that the Market app will take them right there. I am trying to make it as easy as posible. No searching etc. No I have no intent of doing the purchasing from within my app. I want to have them press [Get Paid Now] button and then I start the Market app which would then take them to my Paid Application in the store.

2) Or I could just make separate builds and make it explicit in the code.

I am looking for a way to initiate the audio connection between the Android phone and my headset within my application. The idea is to simplify the connection process in such a way that the user doesn't have to go through the different settings menus anymore (Apps -> Settings -> Wireless & Networs -> Bluetooth settings).
Both devices are supposed to be already paired and the Bluetooth address of the headset to be known.
As far as I learned, the Bluetooth capabilities (available since version 2.0 of the Android SDK) are restricted to Bluetooth discovery and the connection of RFComm channels (host/client) between the Android phone and a Bluetooth device. Is there another way to request Bluetooth profiles on the Android system to initiate a connection to a known device from an app or is this impossible?

View 1 Replies View RelatedI have this resource file for colors
CODE:..................
And this method that gets called when the user clicks one of four colored Buttons
CODE:.................
The problem is the color of the Button doesn't change when pressed. I stepped with a debugger and it actually reaches the right points in the method, so that's not an issue. I think the problem is in pressedBtn.setBackgroundResource(newColor) but I can't understand why. Anyway, if you have a better solution to change a button color when pressed and, after a half second, change back to original color, let me know.
