[android-developers] how to select listview from multiple listviews in main.xml (on Android 2.3.3)
hi all, I'm using FrameLayout and have defined two LinearLayouts embedded inside the FrameLayout. Now for each LinearLayout I've a listview . The problem I'm facing is picking the two listviews separately from my Java side code. The default listivew in XML uses the standard defined ID as *android:id=@id/android:list *and I'm not able to pick the right one. So I decided to give custom ids to each of the list view like this in Layout1: ListView android:id=@+id/list1 android:layout_width=fill_parent android:layout_height=fill_parent / and the following in Layout2 ListView android:id=@+id/list2 android:layout_width=fill_parent android:layout_height=fill_parent / and this is what I'm trying to use to pick the listviews separately, ListView listView1 = (ListView) findViewById(R.id.list1); ListView listView2 = (ListView) findViewById(R.id.list2); With the above code in pace, I'm not getting any compilation errors. But during run time I'm getting errors with this message: * java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'* Are we not allowed to use custom IDs for listviews? If custom IDs are not allowed, then what is the best way to handle the above problem? Would appreciate if someone could point me to the right direction. BTW, I'm actually trying to define two layouts each with its own listview and then I'm trying to animate between two UI screens each using one layout and the default behavior gives only one of the listivew as picked by getListView() which happens to be the 1st one, so my 2nd UI page is not showing any listview.

Re: [android-developers] how to select listview from multiple listviews in main.xml (on Android 2.3.3)
Hi, I believe you are using a ListActivity, which by default looks for a ListView with id @android:id/list. To use custom ids change that ListActivity to a normal Activity.

[android-developers] Using multiple listview inside one activity, how to give focus to each
hi All, I'm using multiple listViews inside one activity. I'm using each listiview in its own UI screen layout, meaning I've two UI screens. Now when I start the app, I get the focus on the first app as I'm able to scroll down/up the list and when I switch to the 2nd listview in the 2nd UI screen, the second listView works fine and I'm able to scroll the list. Next, when I return back from the 2nd listview UI screen page to the first page screen, the list becomes static/freezed and I'm not able to scroll up/down but surprisingly when I return back to the 2nd listView, it still works fine. I'm not able to understand as to why both the listViews work fine initially but after returning back from the 2nd listView the 1st listView stops working/scrolling. To me it feels as if something is locked in 1st listView, when I'm returning back from the 2nd one and we've to enable some short of flag, by saying enable this listView from scrolling/usage as currently this listView is in focus on screen. Would appreciate if someone could point me to the right direction. I'm adding some code snippets below, -- Activity file code snippet -- layout01 = (LinearLayout) findViewById(R.id.Layout1); layout02 = (LinearLayout) findViewById(R.id.Layout2); layout02.setVisibility(View.GONE); .. listView1 = (ListView) findViewById(R.id.list1); listView2 = (ListView) findViewById(R.id.list2); this.adapter = new MovieAdapter(this); listView1.setAdapter(this.adapter); listView1.setItemsCanFocus(false); listView2.setAdapter(new MovieAdapter(this)); listView2.setItemsCanFocus(false); - main.xml layout file: - FrameLayout xmlns:android=http://schemas.android.com/apk/res/android; android:id=@+id/container android:layout_width=fill_parent android:layout_height=fill_parent LinearLayout xmlns:android=http://schemas.android.com/apk/res/android; android:id=@+id/Layout1 android:layout_width=fill_parent android:layout_height=fill_parent android:orientation=vertical ImageView android:layout_width=fill_parent android:layout_height=75px android:scaleType=fitXY android:src=@drawable/title / ListView android:id=@+id/list1 android:layout_width=fill_parent android:layout_height=fill_parent / /LinearLayout LinearLayout android:id=@+id/Layout2 android:layout_width=fill_parent android:layout_height=fill_parent android:orientation=vertical ImageView android:layout_width=fill_parent android:layout_height=75px android:scaleType=fitXY android:src=@drawable/title / ListView android:id=@+id/list2 android:layout_width=fill_parent android:layout_height=fill_parent / /LinearLayout /FrameLayout Appreciate your time.

[android-developers] Forwarding a stream to be accessible from an URL. Idea needed.
Hello, I'm going to implement media streaming in my app, but I'm not sure what is the best approach for this. First of all, I have access to InputStreams from several sources, like SMB network or a ZIP file. Let's say, those streams refer to some media, for example an mp3 file. What I want to achieve, is to forward those streams to the localhost, to be accessible from an URL to other apps. Something like http:// localhost:4567/my_media.mp3. After that, I want to list all activities, that can play my media using that URL, i.e. some streaming apps installed in the system. I just want them to still think that this url refers to some media in the Internet. I know how to do activity listing, but I am unable to find any good idea for the first part. What is the best way to achieve that? Any help will be appreciated. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] OpenGL ES 2.0 weirdness - app works on Samsung Galaxy S2, but not Nexus One or HTC Desire
There are many, many differences between devices when it comes to OpenGL ES 2.0 rendering. It's a profound problem, actually, because it more or less demands that you either buy each kind of device for testing (and there are 600+ devices), or buy graphics engine from someone else who has...neither of which are particularly palatable options from an expense perspective because the value of the app is likely to be far less than the cost of the tool or devices needed to test it.

[android-developers] Re: Fail to connect to camera service
I'm sorry to come up with this subject again but we're going to the
end of December and I'm still stuck in this..it's so demotivating.
I've tried to reach wikitude developers but they don't know how to
help me so if you have the patience or will to give me some
suggestions on this I would be really gratefull. I'll try to explain
with the code to make the things more clear.
I have an activity called BasicOpenARDemoActivity (wikitude activity
that initiates a wikitude camera view) with a method to happen when
the location is changed. If there's a certain proximity to a target a
trigger is called which opens a new intent:
public void onLocationChanged(Location newLocation) {
double picLatitude = Double.parseDouble(picLatitudeString);
double picLongitude = Double.parseDouble(picLongitudeString);
double myLatitude = (newLocation.getLatitude());
double myLongitude = (newLocation.getLongitude());
float R = 6371; // km
float dLat = (float) Math.toRadians((picLatitude-myLatitude));
float dLon = (float) Math.toRadians((picLongitude-myLongitude));
float a = (float) (Math.sin(dLat/2) * Math.sin(dLat/2) +
Math.cos(Math.toRadians(myLatitude)) *
Math.cos(Math.toRadians(picLatitude)) *
Math.sin(dLon/2) * Math.sin(dLon/2));
float c = (float) (2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a)));
float distancia = R * c;
// distancia in KM
if(distancia0.05 ar.equals(1)){
LogToSD.write(AR:, PROXIMITY ALERT);
Intent TNNIntent = new Intent(this.getBaseContext(),
thenNnowMode.class);
Bundle w = new Bundle();
activityName=finding;
w.putString(code, activityName);
w.putString(piclink, picLink);
w.putString(sd, picSD);
w.putString(id, picId);
w.putString(ar, ar);
w.putString(latitude, picLatitudeString);
w.putString(longitude, picLongitudeString);
w.putString(orientation, picOrientationString);
TNNIntent.putExtras(w);
startActivity(TNNIntent);
finish();
}
The activity called after the trigger happens is called thenNnowMode
which initiates a surfaceview and the native camera of android:
Bundle w = getIntent().getExtras();
if (w!=null){
activityName = w.getString(code);
if(activityName.equals(finding)){
picId = w.getString(id);
picSD = w.getString(sd);
picDate = w.getString(date);
picKeywords = w.getString(keywords);
picComment = w.getString(comment);
picLink = w.getString(piclink);
piclatitudeString = w.getString(latitude);
piclongitudeString = w.getString(longitude);
picorientationString = w.getString(orientation);
ar = w.getString(ar);
if (ar.equals(1)){
TNNPicture = BitmapFactory.decodeFile(picSD);
transparencyPreview = (ImageView)
findViewById(R.id.picture);
transparencyPreview.setImageBitmap(TNNPicture);
transparencyPreview.setAlpha(150);
}
}else{
picId = w.getString(id);
TNNPicturePath = w.getString(path);
}
}
A SurfaceView is created on the method onCreate() (I use it to be
able to TAP the screen and take a picture)
tnnSurfaceView = (TappableSurfaceView)
findViewById(R.id.surface_camera);
mSurfaceHolder = tnnSurfaceView.getHolder();
mSurfaceHolder.addCallback(this);
mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
tnnSurfaceView.addTapListener(onTap);
SurfaceView methods
@Override
// Create the Surface and Open the Camera
public void surfaceCreated(SurfaceHolder holder) {
tnnCamera = Camera.open();
}
@Override
// Reacts for camera changes
public void surfaceChanged(SurfaceHolder holder, int format, int
w,int h) {
if (mPreviewRunning) {
tnnCamera.stopPreview();
}
Camera.Parameters p = tnnCamera.getParameters();
p.setPreviewSize(w, h);
tnnCamera.setParameters(p);
try {
tnnCamera.setPreviewDisplay(holder);
} catch (IOException e) {
e.printStackTrace();
}
tnnCamera.startPreview();
mPreviewRunning = true;
}
@Override
// When the camera is closed
public void surfaceDestroyed(SurfaceHolder holder) {
mPreviewRunning = false;
tnnCamera.setPreviewCallback(null);

Perhaps I should give more information about what the app is doing. It uses a single 1024*1024 texture with type GL_UNSIGNED_BYTE. It runs a shader on the texture to perform a palette-shifting animation. The shader compiles without errors, even on the devices where the app doesn't work.

Re: [android-developers] Re: OpenGL ES 2.0 weirdness - app works on Samsung Galaxy S2, but not Nexus One or HTC Desire
1) I would check every GL call's error code after you run it to make sure nothing is reporting an error. If the shader is compiling chances are good that it's okay (there are exceptions). 2) Different devices handle texture unit mappings in different ways. I've had problems binding a texture to a unit and leaving it there. I found that re-binding the texture unit every time I use the shader seems to be portable, if not particularly desirable. Having said that, I haven't found a way to get my own app to run on the PowerVR chips...so...who knows. 3) Check that your really giving it the texture format that you think you are. I remember having problems with the SGS 2 because some textures needed to be bound as 565 instead of unsigned byte. The bad news is that there's really no repository of knowledge for this stuff. You just have to slog through it by yourself or buy an engine that has done it for you. Unfortunate, and unhealthy for Android, but that's just the way it is with Android OpenGL. Fragmentation at its most diabolical. On 12/26/2011 10:33 AM, Michael wrote: Perhaps I should give more information about what the app is doing.

[android-developers] Android onLayout() and AsyncTask() does not work together
Hi experts,
I need a scrollable table with fixed header, so I followed this great
blog (http://blog.stylingandroid.com/archives/432) and everything is
fine.
The idea is using one table for header, one table for content added in
scrollview, both of them are in a customized LinearLayout. In
customized LinearLayout, we will overwrite the onLayout() to get the
max width of each row and set width for each row of both header and

[android-developers] Re: How to pair two devices to transfer file over Bluetooth using NFC
i am using createInsecureRfcommSocketToServiceRecord() function to create the socket and here is the description what it says about function in Android developers ... public BluetoothSocket createInsecureRfcommSocketToServiceRecord (UUID uuid) Since: API Level 10 Create an RFCOMM BluetoothSocket socket ready to start an insecure outgoing connection to this remote device using SDP lookup of uuid. The communication channel will not have an authenticated link key i.e it will be subject to man-in-the-middle attacks. For Bluetooth 2.1 devices, the link key will be encrypted, as encryption is mandatory. For legacy devices (pre Bluetooth 2.1 devices) the link key will be not be encrypted. Use createRfcommSocketToServiceRecord(UUID) if an encrypted and authenticated communication channel is desired. This is designed to be used with listenUsingInsecureRfcommWithServiceRecord(String, UUID) for peer-peer Bluetooth applications. Use connect() to initiate the outgoing connection. This will also perform an SDP lookup of the given uuid to determine which channel to connect to. The remote device will be authenticated and communication on this socket will be encrypted. Hint: If you are connecting to a Bluetooth serial board then try using the well-known SPP UUID 1101--1000-8000-00805F9B34FB. However if you are connecting to an Android peer then please generate your own unique UUID. Requires BLUETOOTH Parameters uuid service record uuid to lookup RFCOMM channel Returns a RFCOMM BluetoothServerSocket ready for an outgoing connection Throws IOException on error, for example Bluetooth not available, or insufficient permissions On Dec 22, 5:27 pm, lbendlin l...@bendlin.us wrote: Everything is working fine but i am getting a pairing request or to match the keys on both the phones which should not come.
