I have a widget on my home screen with several ImageButtons which have default background images. Through the configuration activity, I can change the image on any of the ImageButtons. The problem is that when the screen is rotated, the image on the ImageButton disapears and it changes back to the default image.
I don't know why this happens or how to fix it

I have a very simple widget application which consists of a linear layout with a background and an image button. In the AppWidgetProvider on Update method, I register the click of the button to broadcast an intent. When the widget first loads, everything runs fine and the click is captured. The problem occurs when the screen is rotated, and the click is never captured again even if the screen is rotated back. What do I have to do to re-register the click when the screen rotates? below is some segments of code I am using.
AppWidgetProvider
@Override
public void on Receive(Context context, Intent intent)
{super.on Receive(context, intent);
if(intent.getAction().equals("test.CLICK"))
{Closemouthed(context);}}
@Override
public void on Update(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds)final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i]; RemoteViews views=new RemoteViews(context.getPackageName(), R.layout.widget);
Intent click intent=new Intent("test.CLICK");
Pending Intent pendingIntentClick=Pending Intent.getBroadcast(context, 0, click intent, Pending Intent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.change_mode, pendingIntentClick);
SetInitialLayout(context);
appWidgetManager.updateAppWidget(appWidgetId, views);}
super.on Update(context, appWidgetManager, appWidgetIds);}
Manifest
<receiver android:name=".Widget" android:label="@string/widget_name">
<intent-filter>
<action android:name="android.appwidget.action.ACTION_APPWIDGET_CONFIGURE" />
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="test.CLICK" />
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_mode_switcher" />
</receiver

I want to create an Android ImageButton in the xml file with a background image, and a smaller icon on top of that, right in the center. For some reason, it's not obvious how to do it, and documentation is no help.code...
However, no matter what I try (putting "wrap _ content" instead of absolute numbers on layout _ height and layout _ width, the icon remains in the top left corner of the button. If, however, I have no background image (i.e. a system default white button), the icon does go into the center. The button also goes into the top left corner when I use a color instead of an image for the background.
Why does this happen, and how would I actually get the behavior I want-- that is, a background image with the icon in the center?
I want to show an arrow that indicates the direction towards a goal, using the orientation sensor and current GPS position. Everything works well, except that I want to rotate the arrow image in my ImageView.
View 2 Replies View RelatedThis one surely is a simple one but I haven't made sense of is yet. I'm working on an app in opengl es on android. everything goes well except when I load the textures. I manage to open load and create all the textures without any problem, but the image displays itself rotated of 90. it looks as if the application does not consider that its is in landscape when opening the image...I solved the problem by turning all my textures of 90 degrees but I would sure like to figure this one out Because it is the only thing that is not rotated, the top bar is rotated, the touch coordinated are rotated,
the h and w of the surface are good,
Here are some code snippets that I think are relevant:

View 11 Replies View RelatedA 'Button' view comes up with text, while the 'ImageButton' widget comes up with an image but no text, is there a way to relatively easily (e.g. method calls, say), either:
1. Add text to ImageButton (like those buttons that appear in menu item/via the physical menu button)?
2. Add an icon/image to a Button?
without resorting to constructing a new button class? I.e. I could put text within the image, but then I can't use Localization properly/effectively.
I want to set image dynamically on the ImageButton in android. However, i have more than 200 images. what would be the good solution for that?
The best idea is that i can use the name of image to call different images. i.e. imagebutton.setImage("/res/abc.png");
however, it seems to me that it is not trivial to do so..
I'm porting an application from iPhone to Android. The iPhone app has artwork for some dozen or more buttons in their normal and pressed state. That translated over just fine to Android. However, we of course currently don't have any images for the "focused" state.
Besides the work involved in creating all these focused button images, we're not sure exactly what color to set the focus too. Selection color varies from phone to phone, etc. We'd have to come up with some neutral "white glow" of some sort I suppose. Then the idea struck -- could we programmatically render a focus images for the buttons based on the current selection color? Have folks been doing anything like this in the Android dev community? Can you point me to some examples. A net search didn't turn up anything too useful, though perhaps I searched on the wrong keywords.
I've set the background image of a custom ImageButton I am building, as well as setClickable(true) and setFocusable(true). The button is able to receive focus when I navigate with DPad/arrow keys in the emulator, however, it does not flash orange when it has the focus. It does not appear to change at all when it has the focus, in fact. When I remove the background image, however, the ImageButtons hold orange when they have focus.
What do I need to do to be enable an ImageButton with a custom background image to flash orange when it has focus?
I'm trying to make it so that as long as a user is touching the button, it shows one image, and when the user releases the button, it goes back to a default image.
I'm trying to use a selector to make this happen:
CODE:...............
I've tried a few things with the selector, but it always produces the same behavior: the button starts out with the default image, then I press it and it changes to the "record_on" image and it never goes back to the default image when I let go.
Is there a way to get this kind of behavior with an ImageButton, or should I be using something different?
I am currently trying to customize ImageButton to show different draweables as background of the Button while keeping the image set via the src attribute.
That's my custom_button.xml:

View 2 Replies View RelatedI am finding that performance degrades after one or more screen rotations, and I presume that this is likely to be because an App's main Activity is destroyed and recreated each time the screen is rotated and that my app must be leaking memory when that happens.I have read that, contrary to what one might expect, not all the objects created by an app's main Activity (or in classes called by that Activity) are destroyed when the activity is destroyed. Specifically, I think I have read (although I can't now find where) that if the View uses a large bitmap member object then the Activity's onDestroy() method should be over-ridden and the bitmap should be explicitly recycled.Are there other objects that need to be destroyed or removed when the Activity is destroyed? What about Listeners? Is there a comprehensive tutorial or guide on this subject?

View 2 Replies View RelatedJust a minor problem that maybe I just have a setting out of wack. I have ADW launcher installed, which may or may not be an issue.

All the other views i.e. settings, browsers, etc do this no problem, but the home screen(s) them selves are stuck in a portrait view.

I'm wondering if anyone else has had their email accounts disappear? This has happened 3 times now. The first time was a few weeks ago after having the same accounts for months. The next time was a couple of weeks ago and then it happened again today. I checked my emails when I got to work, and then while I was sitting in a meeting, I picked up my phone to peek at emails and all 3 accounts were gone along with my corporate calendar account. I re-entered the accounts and it loads everything, but this is kind of annoying.

View 3 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?
