I have a TextView in my home screen widget. Can I use the following selector as the background of the TextView so the TextView can be highlighted when clicked? I know I can do it in Activity, but I am not sure about home screen widget.code...

I'm attempting to change the background color of an Android TextView widget when the user touches it. I've created a selector for that purpose, which is stored in res/color/selector.xml and roughly looks like that:
CODE:................
The clickable attribute of the TextView is "true", in case that's of interest.
When I assign this selector to a TextView as android:background="@color/selector",
I'm getting the following exception at runtime: ERROR/AndroidRuntime(13130): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable
When I change the attribute to drawable, it works, but the result is looking completely wrong because the IDs appear to be interpreted as image references instead of color references (as the "drawable" suggests).
What confuses me is that I can set a color reference, e.g. "@color/black", as the background attribute directly. This is working as expected. Using selectors doesn't work.
I can also use the selector as the textColor without problems.
What's the correct way to apply a background-color-selector to a TextView in Android?
I have created a widget to be displayed on android emulator's home screen to display some long text. In my main.xml layout file i've already set TextView properties like singleLine="true", ellipsize="marquee", focusable="true" etc, but still when my widget is displayed on home screen text does not move/scroll.code...
View 7 Replies View RelatedI am working on a home screen widget. I hope this widget can support auto rotation. For example, if the phone is in portrait mode, I want this home screen widget to be 2 cell * 2 cell on the home screen; if the phone is in landscape mode, I want this home screen widget changes be 3 cell * 1 cell on the home screen.

I would like to run the desire without the sense UI and instead just run the plain android UI for a while, my problem is that when I disable Sense I am just left with the Orange home screen selector! Does anyone know how I turn that off and run the basic android? or am I stuck with these skins?
View 3 Replies View RelatedActually this question applies to any widget that requires data from a remote server.
The answer would be pure speculation, but how do you think the widget gets its data? For those that don't know, the widget shows a history of your friends' latest status updates.
Some answers that I can think of:
The widget polls the API directly
The widget grabs data from some
service that's running in the
background, which polls the server
Somehow Facebook implemented push on
Android which I don't think exists
The widget somehow detects that the
user is using the screen and grabs
the data on demand
I am desperately trying to get my head wrapped around how to implement home screen widgets. Right now, I (finally) was able to get a button on my widget respond to a button press setting up an intent filter in the manifest.
However, I cannot for the life of me figure out how to launch an activity when the button is pressed. Basically, here's the code i have...
What I really want to do, though, is start a new activity, not display a toast message. I know it has something to do with pending intents, but I can't figure out how to get that to work.

The layout xml is as below. I have a RelativeLayout, which contains a TextView. The OnClick listener is set on RelativeLayout. The RelativeLayout has a selector background. What I want is, when user clicks on the RelativeLayout, the background of the RelativeLayout should change, and the color of the text of the TextView should change too. Even though I set color selector for the TextView, only the selector on RelativeLayout works. The color selector on TextView doesn't work. How can I implement change of both RelativeLayout background and text color of TextView when user clicks the layout?

Well none of them worked and I'm pretty sure I uninstalled all of them. However on the most right side of the home screen it still says Problem Loading Widget.. Doesn't seem to be causing a problem but it is just really annoying.

View 1 Replies View RelatedI am designing a home screen widget. I ran this widget on a HTC Hero device, which has a screen of 320 pixels * 480 pixels with mdpi. It ran perfect on HTC Hero. The widget takes 3 cells * 2 cells space, i.e. 240 pixels * 200 pixels.Then I ran this widget on a Nexus One device, which has a screen of 480 pixels * 800 pixels, mdpi. Since Nexus One also is mdpi, so I though 240dip is equivalent to 240 pixels on Nexus One and 200dip is equivalent to 200 pixels on Nexus One, so the widget will not take 3 cells * 2 cells space on Nexus One device. To my surprise, when running on Nexus One device, the widget take exact 3 cells * 2 cells, about 360 pixels * 300 pixels, on Nexus One device.I am confused. The layout xml above specifies 240dip in width and 200dip in height for the widget, but why did it take 360 pixels * 300 pixels on Nexus One Device? What am I missing?

View 12 Replies View RelatedIs it possible to apply a custom background to each Listview item via the list selector?
The default selector specifies @android:color/transparent for the state_focused="false" case, but changing this to some custom drawable doesn't affect items that aren't selected. Romain Guy seems to suggest in this answer that this is possible.
I'm currently achieving the same affect by using a custom background on each view and hiding it when the item is selected/focused/whatever so the selector is shown, but it'd be more elegant to have this all defined in one place.
For reference, this is the selector I'm using to try and get this working:

And this is how I'm setting the selector:

View 2 Replies View RelatedThis is more of an annoyance, but whenever I reply to a message off the home screen widget, it automatically defaults to the home number for that contact, instead of replying to the same (cell) number that it was sent from. If I go into the messaging app, it works as it should (replies to the same number).

I have an expandable list with a custom adapter. Everything works great but there are two problems.
First whenever a group or child has a custom background color set the orange selector does not show up. If I dont setup a color the selector draws nicely and also the fade away for context menus works.
Second, some of my text inside a list item is linkified. Whenever a link is present the selector does not draw again. It seems that the click event is handled by the internal link view instead of propagating to the list view.
From Android widget screen guidelines,we know that, home screen has 4*4 cells, and in portrait orientation, each cell is 80 pixels wide by 100 pixels tall. I think these are for baseline HVGA screen. How about for large screens and hdpi screens, do they still have 4*4 cells for widget and each cell in portrait orientation is still 80 pixels * 100 pixels?

View 1 Replies View RelatedActually, what I want is a textview which can show the progress of something, I know progressbar in android,however,so far as I know, it can not contain any text(am I right?), so, I want to change the background color of the textview to show progress,from left to right gradually.
Is there any other way to do this?
I'm battling with extending a TextView for my Android app. I'd like to create "bubbles" to display text messages in a conversation, similar to the native iPhone SMS conversations.
Is there a way to implement the resizing of a background image without just stretching it? I'd like to have a single background image that keeps it's corners but get stretched only in defined areas. I think this should be possible because I've seen it in a SMS app, but I wonder how to implement that.

Can you please tell me how can I place an background image to a the left upper corner of TextView in android? I would like the image not to be scaled by android.
I have tried
Resources res = getResources();
setCompoundDrawables(res.getDrawable(R.drawable.icon48x48_1), null, null, null);
Nothing is shown.
And I have tried
setBackground(R.drawable.icon48x48_1);
But it stretches the image.
