I'm trying to have a gridView with images and on clicking each image, I want to be able to uniquely identify the image that was clicked. Basically the images would be populated dynamically and on clicking each image I want to associate a different behavior. What is the best way to accomplish this?

I'm trying to create a game with a 9x9 grid with GridView. Each item in the grid is a TextView.
I am able to set the initial values of each item in the grid within the getView() method to "0", however I want to change the value of each grid individually after this but have been unable to do so.
I tried adding an update() function in my extended GridAdapter class that takes a position and a number to update at that position but this doesn't seem to be working. code...
Here is my problem : I have a view containing a listView. And each row of this listview is composed of a linearLayout, itself composed of three textview and a gridView. Here is a summary of my layout for one row:
......
I want to perform an action when the user click anywere on an item of the listview. So I try these two approaches on the listview : - myActivity.getListView().setOnTouchListener(new View.OnTouchListener () {...}) - myActivity.getListView().setOnItemClickListener(new AdapterView.OnItemClickListener() { ...}) And here is the trouble : - when I click on the textview, it nearly works : the touch listener is called, but not the clicklistener - when I click on the gridView it doesn't work....the event is just dispatched to the element of the gridView.............
I have been working on creating a Grid View of images, with images being present in the Assets folder. http://stackoverflow.com/questions/1933015/opening-an-image-file-inside-the-assets-folder link helped me with using the bitmap to read it.My application does read the image from the Assets folder, but it is not iterating through the cells in the grid view. All the cells of the grid view have a same image picked from the set of images. Can anyone tell me how to iterate through the cells and still have different images?
View 2 Replies View Relatedwhen I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?
ListView lv = (ListView) findViewById(R.id.resultsList);
lv.setAdapter(new ArrayAdapter(this, R.layout.resultitem, (String[])labelList.toArray(new String[labelList.size()])));
lv.setOnItemClickListener(new OnItemClickListener() {

TextView tv = (TextView)view.findViewById(R.id.result);
tv.setBackgroundColor(Color.LTGRAY);
tv.setTextColor(Color.BLACK);
I have a ListView in my Activity. I am trying to catch both a click and a long click (which should bring up a context menu).
ListView lv = (ListView) findViewById(R.id.MyListView); ... lv.setOnItemClickListener(this); lv.setOnCreateContextMenuListener(this); ...
I notice that if I have both the click and long click listeners up, I won't ever get the long click listener (i.e. the context menu). If I remove the setOnItemClickListener() call, i get a call into
@Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {

I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?
View 1 Replies View RelatedI'm basically using the same method of loading bitmaps in OpenGL that the SpriteMethodTest example uses and have been unable to get rid of an annoying outline that appears around all of my images.
For example, If I were to load an image of a white circle on a white background, I would expect to see nothing. Instead, I would see my circle because its edge would be gray. In SpriteMethodTest, I replaced the background image with white and was able to see that the edges of the android images flying around also don't seem to be rendered correctly.
Does anyone know how to load images in OpenGL without having a thin outline appear around the images?
I'm working to convert some background images to nine patch so they scale better on different phones.
The problem is that if I have the following resource structure: drawable-hdpi/background.png drawable-hdpi/button.png drawable-mdpi/background.png drawable-mdpi/button.png drawable-ldpi/background.png drawable-ldpi/button.png and then I drop a new drawable-hdpi/background.9.png file into the mix, it breaks button.png during the pre-compile. The error is "No resource found that matches the given name (at 'background' with value '@drawable/button').Simply removing that one nine patch file fixes the build. Should I be able to have some nine patch images and some normal ones, or to have nine patch only in hdpi but not mdpi or ldpi? This is Eclipse 3.5.1 with the latest ADT.
When I DL'd the GDE app, I accidentally set my stock droid "HOME" screen as the default screen when the popup box came up asking me to choose between stock Home and GDE. Now when I click on GDE and click the home button, it switches back to the stock Home screen. How to I switch the settings now to set the GDE app as the new home screen?

View 30 Replies View RelatedI am having a similar issue while trying to use a GridView in a PopupWindow. On my Activity's onCreate method, I am inflating a gridview from xml as follows:
CODE:......................
I would like this GridView to popup on a button click. Also inside of my activity's onCreate,
I have:
CODE:............
On button click, I am throwing a ClassCastException from GridView.onMeasure(int, int).
I have a gridview that is inflated by multiple buttons. I used just a gridview and it worked fine. The grid was in correct order and was centered. Although, I wanted to add a button below the grid of buttons that was different and centered. To do this I decided to section off the gridview and then add the button (therefore it wouldn't be affected by the gridview).
I tried the following code to seperate the views:
CODE:...................
The problem is that this code smushes the gridview to the left and oddly it flips it (Position 0 is ont he bottom right and the last button is on the top left pushed off screen). The following image shows what is the result:
Any idea why its pushed to the left and flipped? Or maybe how I could have just the Gridview with the button on the bottom?
I'm trying to use a custom listSelector on a GridView. When I use the default listSelector, I see that it modifies the size of my items so the listSelector display correctly. The list Selector is bigger than my items:
See how when using the default selecto, it make grid items to be resized. Above the gridview I have a LinearLayout with 4 of the same images(ImageView) the GridView contains. http://twitpic.com/2hxkjh
I wanted a custom listSelector, not as bigger as the default (that makes my items smaller), but bigger enough to simulate a border on them without overlap my items content. I'm, not sure if this is an expected behavior, but when I set the listSelector with my own image, I see the selector being fit to my items size. At least my items won't get resized. [url]
Any ideas of how to set a selector that doesn't get resized?

View 3 Replies View RelatedI have a GridView that displays images, which are, unfortunately, of different sizes. They are shown in between two lines of text:
CODE:.........
If IMAGE1 is the same height as IMAGE2, everything is fine, but if IMAGE1 is longer than IMAGE2, text2.1 will run into text3.1 (padding doesn't seem to help much, as there's too much of it when images are of the same height).
I know there's a way to stretch the images in the ImageView so they are the same height, but is it possible to keep images as is and set the row height somehow?
My question is this: i was looking at the "Hello world view: gridview" example and was wondering, how do i load all my images dynamically. for example in the ImageAdapter.java file, at the end there is:

After searching for more than 3h in den the docs and testing I have to ask this question: How can I turn off the orange highlight, when clicking on an item in a GridView?
View 2 Replies View RelatedI'm trying to disable the highlighting of objects in a GridView in Android 2.2. I did find another article saying that I should set the selector to a transparent ColorDrawable, but the views in my GridView are still dimmed when I select them. I'm just using the GridView to display static objects (right now it's text, but I plan on switching it to simple images). None of these objects will be selected. Would it be better to just use a basic view and draw my images manually with quartz?

I'm trying to display an image above and below a grid. This is the initial screen with Logo on top, 4 buttons as a grid view then image on the bottom. With my current code the bottom image is not displaying at all. Also I would like to stick the bottom image "bottomboxes" to the bottom of the display.
View 1 Replies View RelatedI am just wondering if the children of gridview can be shown horizontally instead of vertical view.
Also I have question on performance issues on how horizontal scroll view works.
I have to show 1000 objects and for this I have to create objects and add it to view and scroll view works fine. This seems a lot of memory is there a way we can make horizontallscrollview behave like gridview so that it request for only particular objects to be created when needed.

Can we do a grid view not just with ImageView but with a custom view.
I am trying to make a grid view of a view composed of an ImageView and a TextView.
I know that everything happens in my Adapter getView's function but I can't figure out how to do it.

My view has an id of R.id.fileUnitLayout. Let's say my inner TextView has an id of A and my inner ImageView has an id of B. How can I fill them ?
I need to create a home screen (menu) with four to six items arranged in a grid view, each item needs to have an icon and a text below the icon. I googled and everything I could find were adapterView examples, with dynamic menu loading, and I want to make it with static xml, this view will not change so no need for dynamic code.
View 2 Replies View RelatedI have a grid view of buttons that is generated by a CursorAdapter. When the CursorAdapter is passed to the Gridview the view renders correctly however the first item in the grid does not fire the OnClickListener event.
If I select another button in the grid, the event fires correctly however if I selected the first button then another button, it loads the first button action then the section button action.
When testing this, it only seems to be an issue in Android 2.2 on my emulator, my 1.5 phone works as expected. I've wiped the emulator but that doesn't seem to have made a difference.

Is there a way to force GridView to only be a single row? Right now by default it will extend its height to accommodate all views supplied by its adapter
