How can i include a URL in my tooltip in Google Map?
Here is an image of what exactly i require:
I've built my own content provider and I've run into an instance where I need to execute a query and include a limit param.
The method call to managedQuery doesn't include this param and there fore I see no way to implement this w/o somehow overriding the managedQuery method?
I've created a second query method in my content provider which accepts an additional param, the limit param but I don't think I can make the managedQuery method call this custom query method of my content provider.
What's the best way to do this?
For reference, here is my content provider class...

Is there a way to specify layout_height as a percentage of it's parent?
for example, I want an interview LinearLayout view group to only be 70% of it's parent.
I do not know the difference between these two attributes and for the height also. Take a TextView for example, what would happen if I set its layout_width to wrap_content and set its width to 50 dip?

Can you please tell me which xml file that I am missing? And it said 'binary xml', does it mean it is actually line 26 in my file? or it is line 26 in the file after it compiles to be a binary xml file?..........
View 4 Replies View RelatedI use Layout_width="fill_parent" and Layout_height="wrap content". If an image is bigger than the ImageView, it will be downscaled perfectly.
However, I never got it working to upscale smaller images. I tried any combination of ScaleType and "AdjustViewBounds": it always stays in its own size in the middle of the image view. Here is the code...
<LinearLayout
android:id="@+id/LinearLayout02"
android:layout_height="wrap_content"
android:background="@drawable/content_bg"
android:orientation="vertical"
android:padding="5dp"
android:layout_width="fill_parent"
android:layout_marginLeft="1px">
<ImageView
android:layout_height="wrap_content"
android:src="@drawable/test"
android:id="@+id/ImageViewTest"
android:layout_width="fill_parent"
android:adjustViewBounds="true"
android:scaleType="center"></ImageView>
</LinearLayout>
How can the xml attribute layout_width="wrap_content" be set in code? Don't know where this is buried in the docs...

View 3 Replies View RelatedIs there any way to disable or override the car dock app? I want the application that I am writing to be able to launch when the device is placed into the car dock. I have created a BroadcastReceiver for my app but the standard car dock app displays, not my app. I know that my broadcast receiver is working because when I click the back button on the device from the car dock app it shows my app. How do I get it to not show the car dock app? There is no listing for the car dock app in the list of installed apps on the phone. The only solution I have found on the web is to root your phone and change the .apk file name. I can't expect my users to do that.

View 1 Replies View RelatedI've made a little test component that overrides ImageView, called myImageView, and prints some text and an arrayList of Doubles over whatever image is specified in the related xml. However, right now, the text and Doubles that are drawn over the image are defined within the myImageView class. Is there a way to pass the data from the main onCreate function to the myImageView class before the layout is drawn?
I'm new to OO programming, but based on my understanding of this:
http://developer.android.com/guide/topics/ui/custom-components.html
It's possible because ImageView is just like any other class. This leaves me with two initial guesses:
1. I could generate my test data in the main onCreate, and store it in the array's xml file, and then read that xml file with myImageView,
OR
2. I could extend view instead of ImageView, but because of my new- ness, then I would lose the ability to use it in an xml layout sense - and that's what I really want.
I've got an AVD setup with an SD card, but I wanted to specify a different SD card image by setting a -sdcard option in Eclipse under Preferences -> Android -> Launch (I fill in "-sdcard C:sdcards sdcard96M.img" without the double quotes). But it seems no matter what I do, I always get the SD card that was created with the AVD. From the command line, the following works: emulator -avd myAVD -sdcard C:sdcardssdcard96M.img Do I need to use the command line instead of Eclipse to run this way?

I have an ArrayAdapter wrapped around an ArrayList of custom objects. I'd like to write a custom filter for that adapter so that when I call getListAdapter().getFilter().filter("abc") the list will get filtered by an arbitrary transformation of "abc".
I thought I would just try to override ArrayAdapter.getFilter(), but that requires I re-implement the private ArrayAdapter.ArrayFilter which requires access to a bunch of ArrayAdapter's private instances.
What's the simplest way to do this?

Activating the field calls up the keyboard, and pressing "Done" evaluates mySubroutine() successfully. However, the keyboard no longer goes away when I press "Done". How do I restore this default behavior to the routine?

View 3 Replies View RelatedI currently have an Activity that when it gets displayed a Notification will also get displayed in the Notification bar.
This is so that when the User presses home and the Activity gets pushed to the background they can get back to the Activity via the Notification.
The problem arises when a User presses the back button, my Activity gets destroyed but the Notification remains as I want the user to be able to press back but still be able to get to the Activity via the Notification. But when a USER tries this I get Null Pointers as its trying to start a new activity rather than bringing back the old one.
So essentially I want the Back button to act the exact same as the Home button and here is how I have tried so far:

However the above code still seems to allow my Activity to be destroyed, How can I stop my Activity from being destroyed when the back button is pressed?
