Android :: Change Background Color Of A TextView In Droid?

Sep 29, 2010

Actually, 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?

Android :: Selector On Background Color Of TextView

Aug 28, 2010

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?

Android :: AppWidget On Homescreen : Focus ImageView / TextView With Trackball?

Feb 6, 2010

I coded an AppWidget the user can add to his homescreen. There are a bunch of images (ImageView) in it that perform different actions like starting Activities on click (realised with PendingIntents). To make it easier to navigate through the AppWidget I'd like to use the trackball (as it works with the SearchWidget or FacebookWidget) but I just can't make it work. Here's my layout code for the AppWidget...

So I want to be able to navigate through a bunch of these "Spots" that are all relativeLayouts. How can I make that work out? I'd be really happy about every hint or idea!

Android :: Use Custom Color For Each Textview In Listview That Extends SimpleAdapter In Droid?

May 31, 2010

I have a listview with custom rows and that extends SimpleAdapter.
Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation.
Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row.
To put it as simple:
each listview item has some custom colors the value of which comes from the hidden field.

I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it).

Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other?

Android :: Scale A Background Image Of A TextView For Droid?

Aug 13, 2010

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.

Android : How To Set Background Color On Open GL ES Droid?

Sep 27, 2010

I am currently playing about with lesson 08 here http://insanitydesign.com/wp/projects/nehe-android-ports/ I would like to change the background colour from black to white. In order to do this at the start of onDrawFrame() I have called gl.glClearColor(1.0f, 0.0f, 0.0f, 0.0f); This does indeed set a white background screen, but also results in nothing else showing up on the screen! Clearly this is therefore an incorrect method, but why, and how do I fix it?

Android :: Changing Background Color In Droid Destroy Widget's Appearance?

May 23, 2010

I've noticed that changing the background color of an android widget (f.ex. Button or TextView) by program:

myButton.setBackgroundColor(Color.BLUE);


makes it to loose its 3D shape, border, and shadows effects, and then appears like a ugly flat square. What am I missing?

Sorry for the very naive question but I couldn't get it right although tried for a time.

Android :: Android - Color State List Resources - Specify A Background Color

Oct 17, 2010

To give the user of my app an indication which field currently has the focus I am trying to change the background color of some of my fields depending on the current state, however, I am having troubles understanding Androids Color State List Resources:

There is this example at the bottom of http://developer.android.com/guide/topics/resources/color-list-resource.html. If I try exactly the same, i.e. if I want to adapt the textColor , things do work. However, if I try an only slightly different thing, namely to adapt the background color, things do not work and I don't understand why? Why is this so inconsistent?

To make it simpler to understand what I am trying to do, I append my misc. .xml files:

The AndroidManifest.xml file:

CODE:.........

If I run this as shown here, it works, i.e. I get a button whose text color changes depending on whether the button is focuses, pressed, etc.

If I uncomment the lower button, where I just flipped the attribute values for textColor and background I get an exception, stating

... <item> tag requires a 'drawable' attribute or child tag defining a drawable

What the heck am I missing here? Why is that color state list acceptable as a text color but not as a background color? How does one specify a view's background color depending on the view's state?
