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 in final stage of writing my custom widget (quite similar to Home's sliding panel). it works quite well except one thing: i have some problems with positioning it in FrameLayout (see 3 rightPanel* Panels in main.xml in attached eclipse project).basically i don't like the idea i'm using there: setting layout_marginTop in panelHandle children.

View 2 Replies View RelatedI have the following structure defined in an xml layout file.
<RelativeLayout android:id="@+id/mainLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content">
<FrameLayout android:id="@+id/frame" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" ></FrameLayout>
<Button android:id="@+id/button" android:layout_below="@id/frame" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</RelativeLayout>
The FrameLayout is positioned correctly in the center of its parent. But the Button isn't getting positioned under it. Instead it's displaying in the top left corner. Am I doing something incorrectly or is this a bug with RelativeLayout?
I'm trying to write an app for my Samsung Vibrant (running android 2.1).I used the example "Form Stuff" app available as tutorial on the android developers website. I basically added a background picture to the application. the background picture has some text on it towards the top. I want to display a list of elements (to be selectable by teh user) but I want this list to start from a certain position on the screen (say for example - start from the middle of the screen). tried reading the listview under dev resource and searched the forums but I could not find a way to do this.Could anyone please help me out? or if this is not possible, then suggest me something else which i can place at a certain position on the screen.

Is there a replacement keyboard that has a way to position the cursor without sliding out the useless physical keyboard? I despise the keyboard and would never slide it out if there were another way to move the cursor around.
I wish I liked the Incredible, but I don't. I would pay retail for a Droid without the keyboard and with the cursor function of the Incredible.
I have asked this before, but I never got a response.
I would like to be able to feed an InputStream to the media player, but it does not look like there is any way to do that. The InputStream would feed encoded (mp3 or aac) data to whoever is calling read() on it. The issue is that I may have to stitch data together or I may not have all the data at the time I need to start playing back, but I can get it as the user continues playing.
I see MediaPlayer.setDataSource() for files, streams and URIs, but nothing that seems like an InputStream. I see the JetPlayer which is incredibly thin on documentation. I see AudioTrack, but that requires PCM as input.
So, I'm back to what to use or how I can work around this limitation.
I connected to a server after then, to close InputStream and OutputStream call the code...
But, the streams is still alive. If I make once again, there are 2 different InputStream. Exception does not happen.
How to completely close the streams?
I am trying to parse a Rss2.0 feed on Android using a Pull parser. code...
The prolog of the feed XML says the encoding is "utf-8". When I open the remote stream and pass this to my Pull Parser, I get invalid token, document not well formed exceptions.
When I save the XML file and open it in the browser(FireFox) the browser reports presence of Unicode 0x12 character(grave accent?) in the file and fails to render the XML.
What is the best way to handle such cases assuming that I do not have any control over the XML being returned?
Is it possible to get an InputStream (or file handler) to feed a SAX parser from an XML file stored at the Resources XML folder (instead raw Resources folder)?
View 1 Replies View RelatedIn my Android program, I have some code that downloads a file. This works fine, but since on a cell phone, you can be disconnected at any time, I need to change it do it reconnects and resumes the download when you are halfway through and somebody calls/you lose cell reception/etc. I cannot figure out how to detect the InputStream has stopped working. See the code...
And then my program just hangs on the while( (len1 = etc. I need to make it so when the Internet gets disconnected I wait for the Internet to be connected again and then resume the download.
I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? code...

For one of my apps I generate MIDI data on the fly. Is there any way to play MIDI data from a java.io.InputStream or directly from a byte []? So far I've only seen ways to do MIDI playback from files. Given the continuous and dynamic nature of my audio there is no way I can write it to a file first.

Is there any api on android which generates a Thumbnail image from an inputstream which is a video file?
Thank you.
Doing Android 2.1 development. Can anybody explain to me why the following code generates a IOException and doesn't load the file? This exact code used to work, and as far as I can tell, it should still work. For reference, the Log.d() command correctly lists all files that I expect, and the files are correctly zipped into my .APK file.
CODE:........
Any ideas on why this breaks now? The files I'm trying to read are tiny (couple of bytes) binaries.
My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document.
From this InputStream, I want to have all document in a String.
To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding.
It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error.
Any idea, how to do it ? code...
The the client side of a content provider consumer I can do something like this, to get a proper InputStream for reading the picture: InputStream is = getContentResolver().openInputStream(pictureUri);
It is a nice API, and will on the server side, the actual content provider result in a call to:
CODE:.......
But what if the picture mapped to the URI is not to be found on the filesystem, but as a memory resource, or generated on the fly.
Can I create a memory mapped File or InputStream, or anything else, so that I am not required to save a temporary file to disk, just to be able to return it to my content provider consumer?
I'm building an android app and I'm currently having trouble retrieving a bitmap from an URL.
Here is the code I'm using :
CODE:..........
Everything works fine when the picture's write but when some bytes are wrong, result gets null. I think it's basically expectable as it's written this in the doc of BitmapFactory.decodeStream :
If the input stream is null, or cannot be used to decode a bitmap, the function returns null. The stream's position will be where ever it was after the encoded data was read.
The problem is, my wrong picture is well interpreted by my web browser and I can do so on iPhone platform.
Is there a way to sort of ignore those wrong pixels? maybe with the option parameter?

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.
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?
