Android :: How Can I Get Correct Display Metrics From Widget In Android?
Apr 15, 2010
I need to determine the screen density at runtime in an Android App Widget. I've set up an HDPI emulator device (avd). If set up a regular executable project, and insert this code into the on Create method: Similarly, if I get a resource at runtime using the Resources object obtained from context.get Resources() in the App Widget, it returns the wrong resource based on screen density. For instance, I have a 60x60px drawable for mdpi, and an 80x80 drawable for hdpi. If I get this Drawable object using context.get Resources().getDrawable(...), it returns the 60x60 version. Is there any way to correctly deal with resources at runtime from the context of an App Widget?

I am working on an Android application that displays a list of items when a tab is selected, then displays detail information about an item that was selected from the list :
CODE:............
The details are to be displayed using ImageViews, ImageButtons, and TextViews. The data comes from a database query, so the TextView text and ImageView drawables have to be assigned dynamically.
The correct text from the database query gets assigned to each of the Views. I can see everything being added when I step through the code in the onCreate method of Activity3 in the debugger.
BUT, the drawables are only displayed when I select the first item in the ListActivity. If I select another item, all TextViews display the correct information but the drawables are not displayed for the ImageViews or ImageButtons. It looks like only the backgrounds are being displayed.
The ImageButton drawables are not being dynamically assigned, only the ImageView drawables are. The ImageButton drawables are set in the TableLayout XML that is associated with the activity. Here is one entry :
CODE:..............
Originally, I had android_drawable="@drawable/ic_phone", then tried adding android:background="@drawable/ic_phone", and finally created the following selector (phoneselector.xml) :
If I select the first item again, its proper ImageView drawables are displayed along with the proper text in the TextViews. The ImageView drawables that belong to the other items have no problems being displayed in Activity2's ListView.
The code successfully sets an onClickListener for the button (also in Activity3.onCreate). If I click on what is displayed on the spot where the drawable should be, the phone number is dialed.
The code successfully sets an onClickListener for the button (also in DetailActivity.onCreate).
Has anyone seen anything like this before? I would appreciate any help figuring out what is wrong.
Here are more details because I wonder if the problem has to do with the use of the Views :
The Activity1 extends TabActivity and sets a TabHost view that contains a FrameLayout along with the TabWidget. Activity1 creates the tabs dynamically.
Activity2 extends ListActivity and sets the content to its ListView (via setContentView(getListView()).
When ListActivity.onListItemClick is invoked (item in list is selected), a new Intent is created that contains an identifier in a Bundle and Activity3 is started.
The started activity (in Activity3.onCreate...) sets the content to a TableLayout view defined in a .xml file (via setContentView(R.layout.details.xml).
Here is the code from Activity3.onCreate :
CODE:.................

I want to display search result on the screen, I have implemented in such a way that. From the search form user fill the 'search field' and 'search location' I set values into bean and that bean is static so that I can access it from every where. Then I start search result screen intent using:
Intent mainIntent = new Intent(SearchVenueResults.this, SearchResults.class);
startActivity(mainIntent);
On the 'SearchResults' activity 'oncreate' method I load data on the behalf of static bean which values filled from search form and then display data.
@Override
public void onCreate(Bundle savedInstanceState) { loadDataAndSetupUI();
super.onCreate(savedInstanceState);
}
My question is is it the correct approach to use it or in Android there is another preferable approach?

I apologize if this code looks a bit like a mess (considering the length); I figured I'd just include everything that goes on in my program at the moment.
I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value).
There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code...

For some of the albums/songs it says Unknown Artist but when I look at the files they are all in the proper folders with correct names. I added music using DoubleTwist if that helps.

I was wondering if there is a way to show a widget that I have created inside an activity. I have a weather widget and I also have an app I am working on that I would like to include weather reports in. Is there a way I can just re-use the widget code and make it show inside the weather activity?

I have a widget that displays the picture of some of my contacts and I would like to display the QuickContact card when the user taps on one of the pictures. I know I should be using the method ContactsContract.QuickContact.showQuickContact(), but it requires a View or a Rect as one of the input parameters. My problem is that Widgets only have RemoteViews, so I'm no sure what to pass as the View or Rect parameter.

I would like to create a Home Widget containing a ListView, but I don't know if this is possible and if it is, how to do it. I was using a ListActivity and it was pretty simple, but can't figure out a way to do it using AppWidgetProvider.

hey guys i just bought and installed WidgetLocker and must say that it rocks. But there is one thing i can't get to work. I'm trying to display my battery life on the lockscreen but the widget i have (BatteryLife by CurveFish) does not work. It just shows a depleted battery icon and says "loading" while it never does load. It works fine on my regular home screen but I'd like to have one that is compatible with WL too. Also... i have limited space on my current lockscreen, so my ideal battery widget would only take up 1x1 space. Is there such a thing?
Thanks all in advance.

Is there a simple weather widget that will display the current temperature on my home screen in a small size, like the size of a single icon? Something like what's on the Multimedia screen would be great. I don't want future weather, radar or maps... just the current temperature.

I have a widget layout xml which sets the src to the delivered android widget 4x1 frame image.Here is the widget layout code...
@drawable/widgetinitial holds the widgetinitial.png image example 4x1 at developer.android.com (AppWidget design guidelines).(4x1_Widget_Frame_Portrait.psd) What I am trying to do is display an image inside the delivered frame instead what happens is the frame image goes away and only the image I am trying to display shows up. How can I display the image inside the bounding box or the background?
Another question - I think I saw in a couple of forums AbsoluteLayout is a deprecated feature for Android 2.1 and above. Is that correct? and does using AbsoluteLayout throws any force close or other exceptions?

Quick question - why won't the standard message widget (the "stack" of messages type) show any names, just numbers? The numbers are saved to my contacts etc etc and are on both the sim and phone.
Other than checking the numbers against my contacts or by the content I've no idea who's sending me messages.

I've had my Hero on Orange for 4 or 5 days now and apart from when I first switched on the phone the weather app has just said "No weather data available" and the clock/weather widget has just had my location. I have the "location by cell" thing switched on, and I did manage to get it working once with the GPS, but other than that it just displays my location. It's the same whatever location I am in. The other cities download the weather just fine (London, Paris, New York, etc.). It's not like I'm somewhere tiny either, I am in Bromley. It doesn't make any difference whether I'm using WiFi or 3G.

Is it possible to disable title bar display dynamically after setting the content view by setting the NoTitlebar theme?
All the posts I have read told that any title bar changes we can make only before setContentView() call.
