Android :: ProgressBar Doesn't Allow Control Of Visibility In AppWidgetProvider
Aug 7, 2009
I was trying to set a progress bar to View.INVISIBLE or View.GONE, or View.VISIBLE inside an AppWidgetProvider. However, it doesn't seem to want to do it. Setting visibility works fine with TextView fields or ImageView fields or ImageButtons. However, ProgressBar doesn't seem to work. It doesn't make sense that just the progress bar type isn't supported for controlling visibility. Has anyone else seen this problem?

Just had an odd problem with a TextView. Setting the visibility doesn't seem to work but doing the same on say a ScrollView does. Is this normal?

the code I pasted below works great with the exception of the last view - the textView.
The TextView does not display:
CODE:............
I had a similar problem which came down to an XML layout issue and I'm sure it's a similar issue here only I don't know how to resolve it.
How I can get the TextView to display and perhaps more importantly, direct me to some good android xml layout material?

I have tried a while ago to use these values to be able to have 2 different builds to cover all resolutions on Android Market: <supports-creens android:smallScreens="false" android:normalScreens="true" android:largeScreens="true" android:anyDensity="true" /> Unfortunately it did not worked. Although it is recommended to have one big application for all resolutions sometime it is not possible due to some time and resources constraints. The goal is to have 2 different applications Game and Game HD on the market and Game to be visible only for 240x320/320x480 devices and Game HD to be visible for 480x800 devices.

I have a general question. Is it possible to set the RemoteView of the widget to a WebView? My goal is to push real time updates to the WebView via the comet technique (HTTP long polling), similar to how Google Talk does it on the desktop browser I suppose. Do you think battery life would be significantly impacted with this approach?

Tasker does not seem to function unless I use the motorola control panel and turn on bluetooth, wifi, and gps. If I shut these off via the control panel then tasker does not turn them on at the appointed times and events.Which begs the question, is tasker REALLY turning them off? or are the icons just going away in the notification bar (because they still show as on in the control panel widget)Has anyone else noticed this issue?

I have an app widget that extends an AppWidgetProvider to create an application widget.
I would like the application widget to be idle until an activity in my app runs; actually when a service in my app is started.
Once that service is started, I need to "wake up" the application widget and communicate with it (i.e. tell it things to display).
So I see that AppWidgetProvider simply extends BroadcastReceiver -- so does that mean:
1. I need to call registerReceiver in my service and tell it to filter for certain kinds of events?
2. Can I even do #1, or will an AppWidgetProvider *only* accept ACTION_APPWIDGET_* intents?
3. If #2 is correct, how can I communicate or "wake up" / trigger the application widget?
4. Can I send events to my app widget using sendBroadcast( intent )?
Then, my app widget has some buttons on it, I need to send an intent back to the application (or service). I see you can do that with PendingIntents, but if i send the different intents it to the same Activity, it seems to re-use the first created pending intent.

I would like to pass a value from the AppWidgetProvider to a service. How can I do that? This value is taken from the widget configuration. If this value changes (by going to the configuration again), how do I pass it back to the service? Is there another way to do this?

I have a widget that shows some data fetched from the Internet. I may have multiple widgets visible on the screen, each displaying some data, partly the same as the other widgets. From time to time I re-fetch the data from the Internet and update the widget views. I've modeled this in an MVC style: I have a model which I can invoke a "re-fetch-data" on, and which the views listen on. My questions:
A) Is it wise to let my model be a singleton?
B) Can I rely on that all widgets are served by the same AppWidgetProvider? Or may some of my widgets get served by a different AppWidgetProvider instance? Or, more generally: Is there any guarantee that there will be only one instance of my AppWidgetProvider? If there is only one instance of my AppWidgetProvider, then I could use an instance variable here for the model, and pass either my AppWidgetProvider or the model around where needed. Perhaps a better option?
C) In the AppWidgetProviders onUpdate method, can I be sure that the same "context" object is passed as argument each invocation?

Here is my issue, I want to be able to update a specific AppWidgetProvider (home screen widget) from a custom service class. I have to build the remote view in the service because I'm also doing some networking in there, which takes some time. The problem is that I can't figure out how to update a specific widget (individual widgets can have different update intervals, using the alarm manager). If I wanted to do it from the onUpdate of the AppWidgetProvider I could just call appWidgetManager.updateAppWidget(appWidgetId, remoteView); Does anyone have any experience with this or any suggestions?

I am making a clock widget for the android home screen using AppWidgetProvider. I have it calling the TImerTask class that updates all my values using this code:
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds {
Timer timer = new Timer();
timer.scheduleAtFixedRate(new MyTime(context, appWidgetManager), 1, 1000);
}
In the TimerTasks run() I am setting a bunch of text views to the relevant values. My problem is that this seems to work fine, but it makes my home screen unresponsive, probably due to updating it every second. How do I fix this and still have it update the display at the correct time? (I only need to see minutes not seconds, but I want the minutes to change at the correct second.)

It seems like the convenience functions (onUpdate, onEnabled, etc.) aren't being called in the emulator on Android 2.0. Is this a bug, or are these functions just being eliminated? It would have been nice to see this documented somewhere.

Anyone know if it is possible to add AlertDialog within a AppWidgetProvider class? Here is the code I am working on where I start the AlertDialog on onEnabled function call.
@Override public void onEnabled(Context context) { super.onEnabled(context); Log.v(TAG,"onEnabledWidget"); AlertDialog.Builder builder = new AlertDialog.Builder(context).setIcon( android.R.drawable.ic_dialog_info ).setTitle(R.string.app_name) .setMessage("This is testing") .setNeutralButton("Confirm", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { } }); alertNotSmc = builder.create(); alertNotSmc.show(); //runs when all of the first instance of the widget are placed //on the home screen .........

I'm slighty puzzled about how android's AppWidget machinery works. I reimplemented the AppWidgetProvider's constructor like this:
public class MyProvider extends AppWidgetProvider {
public MyProvider() {
Log.d("TEST", "Creating...")
}
public void onUpdate(..., int[] appWidgetIds) {
// updating stuff here
From what I've read in the docs, I understood that AppWidgetProvider is instantiated once, when widget of that type is added for the first time. If another widget of the same type gets added, it will be managed by exactly that provider.But I just discovered that this is not the case. For each widget I add, android creates a new MyProvider (I see that from 'adb logcat' - it prints "Creating..." for each widget)!I don't understad why. Maybe I got something wrong? Or documentation isn't clear on something. What's the reason of having appWidgetIds passed to onUpdate and other methods if each provider is managing only ONE widget?

I have built a widget that contains a button and an editable TextView (that behaves like an EditText) much like the native Google Search bar widget. How can I access the text that the user has typed into the TextView? In an Activity I would just use findViewById(), but of course I can't do that in the AppWidgetProvider. (I get the error message "The method findViewById(int) is undefined for the type Widget.") So I tried to solve it by using a million casts, like so: String str = (String) ((TextView)((Activity) context).findViewById(R.id.txt_input)).getText(); Unfortunately, with that line present my app crashes. What is the correct way to get references to those Widget elements? I've read all about RemoteViews and Widgets and looked for examples where somebody does this (which seems like it would be common, but I guess not) but I haven't turned up a solution. What am I missing?.....

I'm drawing a ProgressBar in a custom View (SurfaceView) to it's Canvas, and it's drawn as expected. Except that it's not animating, no matter what I do. My custom view is animated properly, but I cant change the progress of the ProgressBar.
I've created the ProgressBar like this:
CODE:..................
And I draw it something like this (slightly simplified):
CODE:........
And I've tried updating it's progress manually as well:
CODE:.................
Any ideas on what I need to do in order for my ProgressBar to animate or change it's progress.

How bad is Desire's screen in sunlight? Read this problem at many places. What's the visibility level while you are out? Is it just that colors are not that crisp in sunlight or one can barely see anything?

I am tryout a very simple thing in an activity. It has three components laid out vertically in a linear layout - button, textview1, and textview2. All I want to do is to toggle visibility of textview1 when the button is clicked. So I have the following onclick handler for the button:
[HIGH]public void onClickMe(View view){
TextView thetext =(TextView)findViewById(R.id.thetext);
if(displayText){
thetext.setVisibility(TextView.INVISIBLE);
} else {
thetext.setVisibility(TextView.VISIBLE);
[code]...
The textview does get visible and invisible but the problem is when the textview is made invisible it leaves a big gap between the button and the textview2. I would like the textview2 to be moved the the position where textview1 was. I think it is something to do with relayout but not sure what needs to be done here. I tried multiple things as shown in the code above.
