Android :: Getting Updated Array Of Data From ListView / Adapter

Aug 10, 2010

I must be missing something simple here.I've searched around but don't think my search query is touching on the right topics to yield results. Anyhow, what I'm after is running through the array of data I bind to a ListView after a "Submit" button has been clicked.

Android :: ListView Scrolling - Array Contain Large Number Of Items

Jun 27, 2010

I have a ListView with a scrolling issue. The Array contain a large number of items. When I try to scroll down, the listview displays the first items again. For example, if the initial view shows 12 items and I scroll down to view the next three, instead of showing 4 through 15, if shows 4 through 12 followed by 1, 2, and three. Debugging the Adapter reports that getView return 4 through 15 just as I would expect.

Android :: Passing An Array To A View

Apr 8, 2010

My background is in C, but I'm relatively new to Java and to Android. I have a question as to whether I'm implementing code in the best way:

As a learning exercise in Java and in meeting the Model-View- Controller pattern, I wrote a simple game. It plays out on a 2D grid owned by the game class, and is drawn to the display by an extended View class. I have it working, but I'm wondering after the fact if I'm going about it the right way.

Here's a simplified version of what I have:

Android : Detect Scroll Position Inside A ListView?

Oct 10, 2009

I'm building a chat room application where new events are being polled for every X seconds. Every time that happens, this code updates the RoomAdapter (a custom subclass of ArrayAdapter) with the new data and scrolls it to the bottom:

RoomAdapter adapter = (RoomAdapter) getListAdapter();
for (int i=0; i<newEvents.size(); i++)
adapter.add(newEvents.get(i));
getListView().setSelection(events.size()-1);

This is fine, except that if the user is scrolling up to glance at the room's history, it's going to jump her down to the bottom when the poll happens. What I'd like to do is have it so that if the user is already at the bottom of the list, it stays there after a poll for new events. If the user's intentionally scrolled upwards, I'd like the user not to be disturbed.

How do I detect when I'm already scrolled to the bottom of a ListView?

Note: I can't do getListView().getSelectedItemPosition(), because as the docs note, calling setSelection when in touch mode does not actually select the item, just scrolls to it.

Android :: Custom Grid View With Array Adapter Out Of Sync With Backing Data

Oct 28, 2010

I'm have a custom GridView Array Adapter. The problem for me is that when the grid list gets large enough to scroll off the screen the gridview and arraylist get out of sync. For instance in my case I have code that checks if an actor is of type director the text color should be red. if you scroll up and down my list enough times all the actors text in my gridview will become red. The thing is that the Gridview appearance actually looks fine its the backing data. Here is the complete class. In the code you can see where I tried to override getItem and getItemId but that didn't fix anything. Code...

Android :: Detect Triple Tap On View?

Jul 20, 2010

I haven't spend much time on Gesture Detector or anything of that sort.

My requirement is very simple, Given a View (any view), how do I detect triple tap on that?

Of course a timer and a counter can help me, but I am looking for something more sophisticated that that.

Android :: Detect When User Taps On View?

Jan 10, 2010

I want to detect when a user taps anywhere in a view in my Android application. My code looks like this:

linearLayout = (LinearLayout) findViewById(R.id.linearLayout); // main layout
// ...
linearLayout.setOnTouchListener(this);
// ...
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(this, "Touch!", 1000);
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Toast.makeText(this, "Down!", 1000);
return true;
}
return false;
}

but when I click on the view, I don't get Toast! Do touch events work in the emulator -- or have I got something wrong in my code?

Android :: Detect If A View's Parent Activity Is Paused

Jun 20, 2010

In one of my Activities I have a ListView that displays a list of locations. For each list item I want a little arrow icon that points in the direction of the corresponding location. I implemented this icon by extending ImageView. This custom View has a listener that reacts to changes of the device's orientation by rotating the icon image accordingly. I register the listener in the onAttachedToWindow() method and unregister it in onDetachedFromWindow(). This kind of works but the problem is that onDetachedFromWindow() sometimes gets called only a long time after the containing Activity has paused. Also, the whole layout overall seems a little hacky. So my question is: Is there a proper way to unregister the listeners or would you implement this in a completely different way to begin with?

Android : Missing Action_Up / Detect Lifting Finger From View

Nov 4, 2010

I've got a view where I override onTouchEvent to detect touching the view with a finger and also to detect lifting the finger from the view. I'm getting the ACTION_DOWN event but not the ACTION_UP event. In fact, onTouchEvent isn't getting called when I life my finger. Could it be that the finger-down and then finger-up is considered a click event and so onTouchEvent is not called? If so, what use is ACTION_UP?

Android :: Converting Byte Rgb_565 Array Into Argb Or Rgb Array

Jan 12, 2010

I have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);

where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);

The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?

Android :: Converting Short Array To Byte Array

Feb 16, 2010

I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?

Android :: How To Detect Android ListView Scrolling Stopped

Nov 20, 2009

I'm trying to do something after scrolling stopped.So, I tried using OnScrollListener#onScrollStateChanged(SCROLL_STATE_IDLE) to detect when the scrolling stopped(either TOUCH_SCROLL or FLING)(at 1.5 it's runs as i expect).

But when it runs on 2.0, onScrollStateChanged can't received the event after releasing the finger.Is there any callback or anyway to detect that event?

Android :: Navigating An Array - String Array

Oct 12, 2010

I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.

Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);

That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.

CODE:................

But Like I said, I would like to just order through them one by one when a button is clicked.

Android :: View And ListView Scroll At Once?

What I have now is a layout that includes a list view at the bottom. All of the items in the layout above the list view remain fixed as you scroll through the list view. I would like the entire page to scroll so for example when you reached the bottom of the list you would no longer see the items above the list view.
