Android :: Add View (dynamically) In Widget (API Level 3)?

Apr 2, 2010

How do I add a View dynamically in an android widget? I realize that the RemoteViews works as a container of updates, but the RemoteViews.addView is only available on API level 7 (and I want my widget to work on HTC Hero phones, which has API level 3).

Android :: Dynamically Add View To Home Screen Widget?

Mar 5, 2010

I am writing a home screen widget. Is it possible to add a View, e.g. ImageView, to a home screen widget through RemoteViews? I want to generate the views for the home screen widget dynamically.

updateViews = new RemoteViews(context.getPackageName(), R.layout.widget_news);

updateViews.setTextViewText(R.id.widget_title, mTitle);

updateViews.setImageViewBitmap(R.id.widget_picture,
BitmapFactory.decodeByteArray(image, 0, image.length));

My code is like above. But we I call updateViews.addView(aView), my IDE didn't allow me to do that and give me an compile error.

Android :: Clone View At Object Level For Performance Reason?

Nov 11, 2010

My question is almost exactly this question:
Clone textview to append it to a ViewGroup
However, I was inflating a view, and then attempting to clone it at the object level for performance reasons (I don't want to parse XML every single time), so that answer doesn't help me. View.clone() is protected and it apparently doesn't have a copy constructor. Is there any way to do this?

Android :: How To Update Widget Dynamically?

May 28, 2010

I am currently learning about widgets in Android. I want to create a WIFI widget that will display the SSID, the RSSI (Signal) level. But I also want to be able to send it data from a service I am running that calculates the Quality of Sound over wifi. Here is what I have after some reading and a quick tutorial: public class WlanWidget extends AppWidget Provider {RemoteViews remoteViews; AppWidgetManager appWidgetManager; Component Name thisWidget; WifiManager wifiManager; public void onUpdate(Context context, AppWidgetManager appWidget Manager, int[] appWidgetIds) { timer timer = new Timer(); timer.schedule AtFixed Rate(new WlanTimer(context, appWidgetManager), 1, 10000); The above seems to work ok, it updates the SSID on the widget every 10 seconds. However what is the most efficent way to get the information from my service that will be already running to update periodically on my widget? Also is there a better approach to updating the the widget rather than using a timer and timertask?

ComponentName thisWidget = new ComponentName( context, WlanWidget.class );
remoteViews.setTextViewText(R.id.widget_QCLevel, " " + qcPercentage);
AppWidgetManager.getInstance( context ).updateAppWidget( thisWidget, remoteViews );This gets run everytime the RSSI level changes but it still never updates the TextView on my widget, any ideas why?

Android :: Dynamically Change Widget Background

Jul 4, 2009

I am working a widget... I'd like to change my widget background image dynamically, is it possible? I tried theme & style, it doesn't want to work. It doesn't show any background image (see code sample below). I tried RemoteViews.setImageViewResource on an ImageView filling the widget, but i doesn't strech my 9patch image correctly (and it doesn't seems to change background, it add another image). Is there a solution? Additionnal question : is it possible to use an external (sdcard) 9patch image as background? if yes: how?

Android :: Dynamically Adding A View To Activity Layout

Aug 18, 2010

I have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).

The book says to fetch the RelativeLayout using findViewById() in my java code then create a new instance of my custom view, then use addView on the RelativeLayout to add the new view.

I'm not getting any errors, but when I click my button to add the new view, nothing is happening (view isn't being added). Do I need to set additional properties on my custom view (layout width, layout height for example) in order for it to be shown?

Android :: Dynamically Enabling / Disabling Widget Does Not Work / How To Fix?

Feb 3, 2010

We would like to enable or disable widgets via code. When we say "disable" we mean that a widget which is registered in an application should not show up in the list of widgets available to the user when they try to add a widget to their home screen. This question has been asked, unfortunately, many times without answer. There was one response by Dianne Hackborn to a separate widget question which suggested that it was possible to use the package manager to disable widgets.

Android :: Graphically Represent Multiple List Selections / Dynamically Change List Item View

Apr 23, 2010

I'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

Android :: Widget Host App With Custom View

Mar 11, 2010

I'm writing an app that will host widgets. The app has custom view (which probably is the source of issue).mView.addWidget() basically just remembers this AppWidgetHostView instance and then mView draws it directly onto canvas. Visually everything is fine.I can see the actual widget. But the issue is with reacting on UI events. Please advise what needs to be done in the parent view in order to correctly trigger handlers in the widgets like onClick().I used standard widgets which normally react on click events. None worked.I also created my own test widget with listener and onClick()is successfully triggered if the widget is added on Homescreen, but doesn't work in my app.mView correctly detects click event and I tried to call widget.perform Click there, which returns false meaning onClickListener is not registered in the widget. But according to source .would call updateAppWidget which would register its onClick listener.

Android :: Populate View Flipper Child View With List View?

As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:

public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............

Android :: Low Level Audio API

Aug 9, 2010

I'm looking for some way in Android to play in-memory audio in a manner analogous to the waveOutOpen family of methods in Windows programming. The waveOut... methods essentially let an application create arrays of sample values (like in-memory WAV files without the headers) and dump them into a queue for sequential playback. Windows transitions seamlessly from one array to the next, so as long as the application keeps dumping arrays into the queue ahead of playback, the program can create and play continuous audio of any arbitrary length. The Windows API also incorporates a callback mechanism that the application can use to indicate progress and load additional buffers.

As far as I can tell, the Android audio API lets an application play a file from local storage or a URL, or from a memory stream. Is there any way to get Android to "queue up" MediaPlayer.start() calls so that one player transitions (without glitches) into the next upon play completion? It appears that Jet does something like this, but only with its own internal synthesis engine. Is there any other way of accessing Android audio in a waveOutOpen way?
