Is it possible to have an index on the righthand side of a ListView? This is possible on the iPhone where running down the righthand side the alphabet is shown. Touching a letter on the alphabet brings one to the beginning of the items in the ListView that start with that letter.
Is there built-in code in Android for this functionality? Or is this something one would have to custom make?

I am using a ListView with an ArrayAdapter that holds objects. When I select an item, I am capturing the position and index of the selected item. If I scroll down prior to selection, the position and index represent the location of the item in the list. Selecting that items takes me to another activity. When I use the back button to return to the list, it seems that the ListView gets a new position and index for the visible items.
As a result, I can't figure out how to reference the selected item during the restart() of the ListView Activity. I have tried to capture position and index, but as I've said, they change upon returning to the Activity.
Is my understanding of the ListView "redraw" correct? Does it renumber my items based on what's visible? -When in the life cycle is getView() called? Is there a way to force an update to the ListView so that my captured index still points to the same object?
Now i want to write an application to make a certain text to run slowly from right side screen to left side screen and rotate to repeat. How can i do that?

I was wondering how i would do this myself to any app that i choose
I think what its doing is forcing tablet UI in certain apps..
Opinions aside, it seems useful to have some lists developed in here with actual comparisons of the relative merits of each of 1.5 and the 2.1 leak.I'm hoping the thread does not degenerate into allegiances for one or the other so much as real data, although the experience users are having is part of the equation and should be commented on.2.1 has this or that, but 1.5 does not. 1.5 is more stable in this area, but 2.1 is not. .. etc.
View 39 Replies View RelatedI'm looking for a way to put three ListViews side by side. Documentation specify that ListView "displays a scrolling single column list". As I'm a bit stubborn, I've done some tests but I only manage to display one ListView which fill all the screen even if I use "wrap_content" or if I put each ListView in a LinearLayout. The final goal is to connect these ListViews together, clicking on an item from the first will update the content of the second, and so on.Should I user ScrollView instead ? For those who will say that three ListViews won't fit in a mobile screen, I trying to make an application for a tablet :)

But on Gl to sd download page it is said that it will interfere with other mount scripts and all that. My question : is it safe to use Gl to sd and link2sd side by side, or will it cause any problems???

How to retrieve the index of linearLayout which has "llIndex" as id.
I have an Android ListView created with a SimpleAdapter that has more items in it than fit in the screen. After the list has been scrolled, I need to get the position in the data model of the first visible item in the list.Basically I want a function like: listView.getChildAt(0).getPositionInDataModel().Adapter has a few functions in it, like getItemId(position) that looked useful; however, the SimpleAdapter implementation just returns the passed in position, not a row id like I'd hoped.A brute force solution would be to get the View at index 0, and compare it to the view for each item in the adapter.However, there doesn't seem to be an easy way to get the view for a particular position from the adapter.
View 3 Replies View RelatedI want to obtain the index of the selected item in a spinner.
I am aware of the method getSelectedItem() which returns the item selected (which might be a String). But i want the index of the selected item.
Something equivalent to the setSelection(index) to set the selected item.
Of course I can get the selected item and compare it against the array of items to obtain the index, but I hope there is a better way of doing this.
I added android:fastScrollEnabled="true" to the xml description of my listview class. I was (probably mistakenly) expecting this to magically transform the scrolling of my really huge listview so that the thumb button and the indexes display on the right side.
Is there more to hooking up the listview so that the framework knows what its alphabetizing? I have custom defined cells.
I have a binary file which contains keys and after every key there is an image associated with it. I want to jump off different keys but could not find any method which changes the index positioning in input stream. I have seen the mark() method but it does not jump on different places.
Does anybody have any idea how to do that?
I'm using OpenGL ES to display some objects exported from Blender. Blender provides a list of vertices, a list of the face indices and a list of the 2d texture co-ordinates. Within Blender, and I believe generally in OpenGL, the texture co-ordinates map to each vertex described in the index array.
I suppose I have two questions:
I'm given to understand(see the "Applying Textures" section) that in OpenGL ES the texture co-ordinates map to the vertex buffer only, not the index buffer. Is this the case or is there a way of binding the texture co-ords to the index buffer instead?
If the above is true, is there anything to be gained from using an index buffer at all? After all to properly map the textures one will need to write out the vertex buffer with all the redundancy that would have been saved with the index buffer. Is there still a performance increase to be gained or are index buffers redundant for textured data?
i have a map file which has several tile images in the form of binary data. now i have to jump my index to different location of the file and read that tile. but i could not find anything helpful for me i also checked mark() and skip() methods.but not helping me.is there any method or class which can do what exactly i want or any hint you want to give me.

I have a problem with ArrayList. I'm using ArrayList like this:
CODE:.........................
Where Playlist is a class inherited from another ArrayList.
I do the following:
CODE:.........................
Later, when I use 'p' to get the index in the list:
CODE:.................
an index of '1' is returned, even though inspection of the list clearly shows that it's index '4'.
why this fails?
Same problem without indexOf(), using equals():
CODE:............
New edit:
This WORKS:
CODE:.............
Solution:
As suggested, I changed the Playlist class to not enherit from ArrayList, but rather keeping an instance privately. It turned out that I only had to implement 4 ArrayList methods.
This does the trick; Now indexOf() returns the correct object!
Is someArray[index] a faster way to get to a value than someObject.field?
E.g.: if(intArray[i] == 42) {//do stuff}
VS
if(someObject.x == 42) {//do stuff}
I will try to test it soon and post the results; just wondering if you all had any thoughts.
I am creating a list .. the elements of the list are drawn from sqlite database .. I populate the list using ArrayList and ArrayAdapter ...upon clicking the items on the list I want to be able to fire an intent containing info about the item clicked ... info like the index number of the item .. using the method : onItemClick(AdapterView av, View v, int index, long arg)
I do get index of the item clicked . however it is of the list currently displayed . the problem comes when I do setFilterTextEnabled(true) , and on the app type in some text to to search some item ..and then click it ..rather than giving me the index of the item on the original list it gives me the index on filtered list..
following is the snippet of code:
myListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> av, View v, int index, long arg) {
Intent lyricsViewIntent = new Intent(iginga.this, LyricsPage.class);
lyricsViewIntent.putExtra("title", songList.get((int)arg).getTitle());
lyricsViewIntent.putExtra("id", songList.get((int)arg).getSongId());
startActivity(lyricsViewIntent);
}
});
myListView.setTextFilterEnabled(true);
Is there any way I can get the original index /position of the item instead of the one showing in filtered text ...when filtered.
