Android :: Widget With Changing Text

Aug 17, 2010

I'm attempting to create an incredibly simple widget that changes the text displayed every 5s or so. However I've had major headaches attempting to get this to work. Obviously I can't use the onUpdate call as it's a minimum of every 30min. Currently my solution uses an Timer in an extended Service class, which is as ugly as hell and tends to run like a dog after a while. Is there a "clean" way of doing this, ie. in a manner that doesn't require a Widget, UpdateService, Timers etc.

Android :: Changing Text Color Of A Substring Drawed In A Text View

May 10, 2010

I want to change the color of a substring while it is drawed in a text view. For example, if I have this text: "Hello this is a text in black color and (COLOR_RED_BEGIN)this is a text in red color. (COLOR_RED_END)", then when the text view draws the text the substring "this is a text in red color." must be drawn in red.

Android :: Changing Widget Settings?

Jul 29, 2010

I just bought Beautiful Widgets for it's compact time/weather widget, (gained another row of icons on home screen) When you first create a widget with this, there are many configuration options, but it appears the only way to change something is to delete the old widget and create another one. Is this true, or is there a way to edit the options for an existing widget? EDIT: Found the answer in another forum. Tap the weather icon. then menu. I'd delete this, but I can't find an option to delete my post.

Android :: Changing Widget Layout Programmatically

Dec 7, 2009

Let's say that I have two layouts for a widget: Layout1 and Layout2. The default for the widget is Layout1, but I allow the user to choose which layout they want the widget to be. So if the user changes to Layout2, how do I programmatically change the layout to Layout2? There isn't a setContentView method for widgets like there is for Activities.

Android :: Changing A Widget's Icon From OnUpdate

Dec 29, 2009

I have a widget that is meant to change its icon every time it receives the Update broadcast. However, the widget never manages to display its icon properly, displaying the text "Problem loading widget". The Logcat message is: WARN/AppWidgetHostView(612): updateAppWidget couldn't find any view, using error view
WARN/ App Widget HostView(612) : android.widget.RemoteViews$ActionException: can't find view: 0x7f060003 The code for my onUpdate is: public class ImageWidgetProvider extends AppWidgetProvider{private static final String TAG = "Steve"; public static final int[] IMAGES = { R.drawable.ic_launcher_alarmclock,/*and many more*/}; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){for (int appWidgetId : appWidgetIds) {Log.d(TAG, "onUpdate:"); int imageNum = (new java.util.Random().nextInt(IMAGES.length)); Log.d(TAG, Integer.toString (IMAGES[imageNum])); RemoteViews remoteView = new RemoteViews(context.getPackageName(), R.layout.widget); emoteView.setImageViewResource (R.id.image_in_widget, IMAGES[ imageNum]);Now when I hover the mouse over "R.id.image_in_widget" it brings up that its value is equal to 0x7f060003 - the view that it can't find according to Logcat. Using the second Log statement, I verified that IMAGES[imageNum] does indeed refer to a random image from the IMAGES array. (In case it matters, it comes out as a decimal value rather than a hexadecimal one.) Any ideas what I'm doing wrong? Edit: Here is the layout file for the widget, where the image_in_widget ImageView is declared.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:name="@+id/image_in_widget"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/

Android :: Redrawing Widget When Changing Orientation

Apr 26, 2010

I have a widget set up and it displays properly in both portrait and landscape when added to each. But when I change orientation it has the problem "Problem Loading Widget". I delete this, re-add the widget, and it displays correctly. Thus, my widget can support both portrait and landscape but it doesn't survive an orientation switch. What am I missing? Do I need to redraw the widget when orientation is changed? Doesn't it do this automatically? Do I need to call onUpdate() somehow?

Android :: Changing Linear Layout In Widget

Apr 28, 2010

I have this really annoying problem:In my widget, i would like to change the background by code. I noticed on the Google doc than I can easily change the background of an Imageview: remoteViews.setImageViewResource (R.id.my_iv, R.drawable.my_bg);Ok, too easy, i want to change now the Linear layout.. What I read about the remoteview id that I can change a Bitmap, Int, Bool, String, etc. but not a drawable. So i guess i cannot use:remoteViews. set Bitmap (R.id.my_ll, "setBackgroundDrawable",BitmapFactory.decodeResource(context.get Resources(), R.drawablemy_bg));I am totally disapointed and tried a last idea: views.setInt (R.id. my_ ll,"setBackground Resource" ,R.drawable.my_bg);But The logcat told me: android. widget. Remote Views $Action Exception: view: android. widget.LinearLayout can't use method with RemoteViews:setBackgroundResource(int)I am totally lost and I really don't know what to do.

Android :: Widget Buttons - Images Changing The Layout

Nov 21, 2010

I can write a widget with a Button or ImageButton and assign a StateDrawable as background or sourcein order to make an effect when you click it. Besides that I have problems with the side of each button, my main problem is this: how do I change the StateDrawable if I want to change the image of the button from the AppWidgetProvider but still want to preserve the click effect like a StateDrawable. The power control widget in Android does things like that.

Android :: Populate EditText Widget Text From Another EditText Widget Text

Jan 6, 2010

I am trying to populate the text of a second EditText widget with the text from the first EditText widget only when the second EditText widget receives focus, the second widget is not empty, and the first widget is not empty. When I run it and click into the second widget it does not populate. When I remove the third constraint ('etxt.getText ().toString().trim() == ""')) it works. so getText() on the second EditText widget is returning something even though the second widget has no initial value other then the text that is displayed via the hint attribute.

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 : Changing How Many Text Messages To Display?

Jun 19, 2010

I have a Droid Incredible and some conversations are taking a while to open because of the amount of texts in the conversation. Is there any way to change how many texts to display so it speeds up without having to delete the texts? (I like being able to go back to past conversations so I'd prefer not to delete any)

Android : Changing Text Value Of A Textview Dynamically

Nov 9, 2010

I have a textview in my XML layout file, but when I try to change its text value with code pragmatically (dynamically, depending on which button the user clicks) then the text of the textview doesn't change.

This is the code that I tried:

TextView userText = (TextView) findViewById(R.id.User);

userText.setText(bundle.getString("user"));

In debug mode, I can see that usertext has the changed text, but the change doesn't appear on my mobile window... I don't know why.

EDIT: SOLVED! it was a problem with my relative layout, text is out of the window!

Android :: Edit Text Image Changing Look When Given At Run Time

May 5, 2010

I am having an EditText. If i specify image for the EditText in the layout XML file (android:back ground) it looks different and looks different when i specify it at runtime EditText et = (EditText)find ViewById (R.drawable .et1) ; et.setBackgroundDrawable (Main.themes.getDrawable (EDRAWABLES.EditText Backgro­undImage )); Both codes point to the same image. When i specify the image at runtime , the EditText leaves a margin at the top and bottom of the cursor in the edittext which does not happen when i do it in XML. I have attached the screenshots of both images. Top image is the one drawn from XML and bottom one is given at runtime. I am not getting the difference ? Actually i am facing similar problems with other Widgets too if i change the logic of specifying the drawable at runtime and not at compile time.. Is this the default SDK behaviour?

Android : Alert Dialog With Dynamically Changing Text On Every Request

Jun 5, 2009

I want to show an AlertDialog with one option that might change on every request. So for example at one time I want to show the option "add to contacts" while another time it should be "remove from contacts".

My code does work on the first time, however Android seems to cache the AlertDialog so that onCreateDialog is not executed next time. Therefore the option doesn't change anymore. Can I prevent this caching, or is there just another way of changing the option?

I am working with SDK 1.5 but using 1.1. Code...

SetText Changing Wrong Text

Feb 25, 2013

I've searched using a couple of the above keywords and found nothing.Basically I have a layout with a few textview elements a few edittext elements and a few buttons. In the java any incorrect entries by the user in the edittext elements should change a textview element which acts as user instructions to prompt the user to make corrections, the problem is it actually changes one of the button texts. Here is the code for the layout (activity_main.xml):

Code:
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/button4"
android:layout_marginTop="26dp"
android:background="@color/yellow"
android:gravity="center_horizontal"
android:text="@string/hello_world"
android:textColor="@color/red" />
[code]..

I know this worked as intended when I only had buttons 1-3, but adding 4 and 5 seems to have started something odd, I can't see anything wrong so am guessing this is a stupid mistake on my part. For reference it is button4 which has it's text changed by the java code. My only thought was that this was something more complicated caused by relative layout and inheritence.

Android :: After Changing A Preference - A Setting - Text Showing Settings Doesn't Update

Apr 13, 2010

I will try to explain a simple app scenario: My app goes right to a 'main view'. In this main view I have inserted a 'TextView' which displays current settings created by way of the PreferenceManager. For simplicities sake, let's say I have a checkbox in my settings. When I first start my app - the TextView on my main view shows my checkbox setting correctly (true). Now I go to the settings menu, it pops-up, and then I change it to false. I go back to the main view and...no change. It still say's true even after I changed it to false. If I end the app and then re-start it - all is well and it shows my change.

Apparently the main view just stays in the background while I'm changing settings? How can I redraw or update the main view after I change settings?

I do not yet have the incredible but am considering it. I have never had a phone like this, I have had my env2 for two years. I never liked using the keyboard when you open it, I am so much faster doing it on the front screen with itap on the numbers. Does the droid have a setting like this where you can change it from a keyboard to a number pad and text that way? Help would be appreciated, I am a big texter and it will be a big factor.
