How can I know the state of the gallery and if it is still scrolling? I can't use "setCallbackDuringFling(false)" because I have a textview under the image that has to be updated during the scrolling.
View 2 Replies View RelatedI am working on a application, in which I want to show Image gallery containing full screen images. I have put the gallery in the application successfully. But I am failing to apply some properties to the gallery as per the app design demands. I am using android.widget.Gallery library of android. The things I am failing to do are:
1) I wanna scroll the gallery images one at a time, as now its getting scrolled more than one images in one scroll.
2) And on scrolling the gallery, the images coming next from left/ right should move smothly into the screen and should stop at the screen edges. It should not scroll beyong that in one scroll.
I have a gallery with 7 images.
how can i got the position when stop the scrolling of gallery?
I loaded some images into a gallery. Now I'm able to scroll but once started scrolling the scrolling won't stop. I would like the gallery to just scroll to the next image and then stop until the user does the scroll gesture again.
This is my code

I believe this is pretty trivial but I can't get it to work. I want to display a default image in gallery elements (ImageViews) while their actual image is being fetched from the net. Right now, nothing is shown for an ImageView which its image has yet to arrive. Once it arrives it is immediately shown. What I tried is right after the instantiation of the ImageView to call its setImageResource function like so:
final ImageView i = new ImageView(mContext);
i.setImageResource(R.drawable.loading);
But it doesn't seem to work. Below is the full getView() function.
public View getView(int position, View convertView, ViewGroup parent) {
final ImageView i = new ImageView(mContext);
i.setImageResource(R.drawable.loading);
// if the drawbale is in the buffer - fetch it from there
Drawable bufferedImage = DataManager.getInstance().getImagesBuffer()[position];
if (bufferedImage != null){ i.setImageDrawable(bufferedImage);
BitmapDrawable drawable = (BitmapDrawable) i.getDrawable();
drawable.setAntiAlias(true);
} // if drawable is not in buffer - fetch it from the net via AsyncImageLoader
else { String imageUrl = DataManager.getInstance().getImageBufferInstance().getImageUrl(position);
Drawable downloadedImage = AsyncImageLoader.getInstance().loadDrawable(imageUrl, new ImageCallback() {
public void imageLoaded(Drawable imageDrawable, String imageUrl) {
if (imageDrawable == null) { imageDrawable = getResources().getDrawable(R.drawable.icon);
} i.setImageDrawable(imageDrawable); BitmapDrawable drawable = (BitmapDrawable) i.getDrawable();
drawable.setAntiAlias(true);
} } ); i.setImageDrawable(downloadedImage);
} i.setLayoutParams(new CoverFlow.LayoutParams(Utils.getInstance().getScreenWidth() / 2, Utils.getInstance().getScreenHeight() / 2));
i.setScaleType(ImageView.ScaleType.CENTER_INSIDE); return i;
Gallery in Android is only horizontal scrolling support. And we want make one with vertical scrolling support.
We got plans below. Can anyone give us some advice about which one is right?
1) Linearlayout ( We think it's bad)
2) ListView ( We think it's a good option and get a little worry about performance--too many pictures!)
3) subclass of AbsSpinner like Gallery and do something like Gallery source.
Which one is easy, time-saving and less performance or other problems.
I implemented a gallery, and inside it I have many listviews from left to right. For some reason Gallery works great with all views but not with listview. With listview, when scrolling on the gallery, sometimes I get little jumps.
Some notes: The gallery uses an adapter to find out what to show, and then the listview is created based on the adapter
I'm new to Android and I want to make an image gallery where each column is a category, and users can scroll both vertically and horizontally. I found a useful post about how to display list of images here. I'm wondering if it's possible to nest lists of image inside of a gallery view?
View 1 Replies View RelatedI am looking for the following that I haven't been able to find by searching:
-Widget with different sizes
-Widget will automatically slideshow from selected drawers at a set interval (with random as option)
-You can scroll through the photos by swiping, preferrably seamless (with launcher that allows scrollable widgets I guess) so you can scroll really quick
-Clicking a picture will bring you its source
Would this be possible (or is there such a widget already)?
I have gallery which contains a listview.
when you scroll sometimes the views inside the listview doesnt appear. i can see a shadow which belongs to listview but nothing inside listview appears
i have tried using invalidateviews on listview whenever the view becomes selected.
I am not sure how to resolve this.

I'm trying to set the selection of a Gallery in code. I would like to have the Gallery smoothly roll down a few items over the duration of a second or two. At frist glance, it appears that two members would to the trick:Gallery.setAnimationDuration(int animationDurationMillis); Gallery.setSelection(int position, boolean animate); It turns out that the setAnimationDuration only seems to affect the rubber-bandy "return-to-center" effect of the Gallery. In other words, when a gallery comes to rest after a fling, and a gallery item is off center, the animationDurationMillis is used to control the duration of the Gallery centering up the item. However, the value seems to have no effect on the setSelection. No matter what value is set with setAnimationDuration, the Gallery seems to render about 2 or 3 frames when flying between items 1 and 10 for example. Is this working as designed? Does anyone know a trick or workaround that would let me properly animate setSelection? I'd be especially grateful if we could do it with an "Ease Out" effect.

View 2 Replies View RelatedIn my application I change layouts very frequently with most of the user interactions. Each time when a new layout is drawn, the applications memory size is increasing. I can see this in DDMS. This is absolutely fine. I have analyzed my application with memory analyze tool and it shows that there around 42 Table layouts at some point of time and this number increase as user does more interactions with the app. Now my question is why doesn't the GC collect the stale layout objects. Does GC collect on UI widgets also??? I feel it does but can any one tell me what may be the reason for GC not collecting my UI elements.
View 4 Replies View RelatedI need to add some parts of my UI programmatically. I'm doing this because I need to set the ids of some elements up in such a way that they can be easily access in a for loop. So far I have this xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/attr_row" android:layout_width="fill_parent"
android:layout_height="wrap_content"> <EditText android:id="@+id/attr_name"
android:hint="Attribute" android:layout_width="0dip" android:layout_weight="2"
android:layout_height="wrap_content" android:inputType="textPersonName" />
<EditText android:id="@+id/attr_val" android:hint="Value"
android:layout_width="0dip" android:layout_weight="3"
android:layout_height="wrap_content" android:inputType="textPersonName" />
<ImageButton android:id="@+id/drop_attr" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:background="@drawable/btn_delete_states"
android:layout_gravity="center_vertical" /> </LinearLayout>
At the moment, I inflate this xml five times like so:
for (int i = 0; i<5; i++) { LinearLayout attrList = (LinearLayout) findViewById (R.id.attr_list);
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.attr_row, null);
LinearLayout extraAttr = (LinearLayout) row.findViewById (R.id.attr_row);
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
attrList.addView(extraAttr, i, params); }
The link below shows two pictures - the layout hierarchy and the result in the emulator. http://picasaweb.google.com/bengoldcross/Android?authkey=Gv1sRgCJ785I...
As can be seen, the xml is inflated five times successfully but only one is actually displayed. Inspecting the hierarchy viewer a bit more explains why. The layout being displayed is at location x=0 y=111 all the others are being rendered at x=320 y=111. It would appear they are being displayed a) off screen and b) on top of each other. So, why are they and how do I stop it from happening?
Here's a quote from Android's Dev Guide: A central feature of Android is that one application can make use of elements of other applications (provided those applications permit it). For example, if your application needs to display a scrolling list of images and another application has developed a suitable scroller and made it available to others, you can call upon that scroller to do the work, rather than develop your own. Isn't it a bad practice to make an app dependent on other apps?
View 2 Replies View RelatedI was wandering if there was a easy way to do the following without android layout
place an image central top

well I can't figure out a way to place the elements as I want using stupid xml layout.
I have a database filled with records in the following format: . What I want my application to do is select records from an external database, and display those records on the phone screen using a SurfaceView.
Currently, I have an Activity, and a Service responsible for the record-gathering portion of the application. The Activity passes an intent to the Service, and the Service responds by returning the records that need to be displayed. The records are stored in my program as instances of the Data class, and merely have the screen-coordinates of where the element should be drawn in the View (I am just drawing a circle for every record in the DB).
For the sake of brevity, I won't include the service but I will include a skeleton of the Activity class and the Data that I wish to display.
CODE:.................
The problem that I am having pertains to the SurfaceView. I realize that many people are going to suggest that I use just a regular View, but my application involves a lot of elements, so a SurfaceView would be much more suitable for my needs. Below is a skeleton of my SurfaceView class that contains a nested class to manage the threads.
CODE:............
The problem that I'm having is that once I make the initial call to the Panel class, I'm going to be getting new records from the service, and consequently, my Info Map data-structure is going to get updated. However, my Panel class just gets stuck in a loop and never receives any new Data objects. All examples of SurfaceViews I've found have involved updating them methods within the SurfaceView class itself (e.g. touching the screen and creating a new image, etc.) Sadly, I'm stumped on this particular problem. Is there a better approach for designing my Activity/SurfaceView interaction? Is an additional View required?
From http://d.android.com/guide/topics/ui/declaring-layout.html, it said "Instantiate layout elements at runtime. Your application can create View and ViewGroup objects (and manipulate their properties) programmatically."
Can you please tell me how/where I can find example for that?
For example, how can I convert the following layout into Java code of my MyWidget. So that when I put "<MyWidget...>" in my layout xml file, it will automatically build a Gallery inside the MyWidget? code...
