  • Android - Loop Through strings.xml file

    - by Alexis Cartier
    I was wondering if there is anyway to loop through the strings.xml file. Let's say that I have the following format: <!-- FIRST SECTION --> <string name="change_password">Change Password</string> <string name="change_server">Change URL</string> <string name="default_password">password</string> <string name="default_server">http://xxx:8080</string> <string name="default_username">testPhoneAccount</string> <!-- SECOND SECTION --> <string name="debug_settings_category">Debug Settings</string> <string name="reload_data_every_startup_pref">reload_data_every_startup</string> <string name="reload_data_on_first_startup_pref">reload_data_on_first_startup</string> Now let's say I have this: private HashMap<String,Integer> hashmapStringValues = new HashMap<String, Integer>(); Is there a way to iterate only in the second section of my xml file? Maybe wrap the section with a tag like <section2> and then iterate through it? public void initHashMap(){ for (int i=0;i< ???? ;i++) //Here I need to loop only in the second section of my xml file { String nameOfTag = ? // Here I get the name of the tag int value = R.string.nameOfTag // Here I get the associated value of the tag this.hashmapStringValues.put(nameOfTag,value); } }

  • Database design: Using hundred of fields for little values

    - by user964260
    I'm planning to develop a PHP Web App, it will mainly be used by registered users(sessions) While thinking about the DB design, I was contemplating that in order to give the best user experience possible there would be lots of options for the user to activate, deactivate, specify, etc. For example: - Options for each layout elements, dialog boxes, dashboard, grid, etc. - color, size, stay visible, invisible, don't ask again, show everytime, advanced mode, simple mode, etc. This would get like 100s of fields ranging from simple Yes/No or 1 to N values..., for each user. So, is it having a field for each of these options the way to go? or how do those CRMs or CMS or other Web Apps do it to store lots of 1-2 char long values? Do they group them on Text fields separated by a special char and then "explode" them as an array for runtime usage? thank you

  • How can I separate Logic/UI in Android

    - by Ungureanu Liviu
    Hi, I want as my application to be structured in 2 parts: the logic code and the UI. I've tried to implement that using a controller class(here I keep the logic code) inside of each activity. The activity send messages to controller and receive the answer in two ways: the answer is returned immediately (if the action is not complex and it can be done in a verry short time) the activity set some listeners and the controller fire this listener when the action is complete. The problems appears when the controller have a lot of objects(each object should handle a set of actions and for each action I have to set & trigger a listener): it is hard to keep the code syncronized. I'm asking if you know a better way to implement this mechanism. Thank you.

  • How to change size of Android ScrollView

    - by user611923
    I have a layout like this (abstracted): Scrollview - fill_parent LinearLayout - wrap_content ImageView 1 - wrap_content ImageView 2 - ... ImageView 3 ... In the course of user interaction some images are replaced by larger or smaller ones, shortening or lenghtening the area to be scrolled. And that is the problem. The Scrollview (SV) does not know about the change, so either it scrolls over a lot of empty space at the bottom, or cuts off a picture or two at the bottom. Question 1: Can I somehow make the SV readapt to the changed hight of the LiearLayout (LL)? Question 2: I can obtain the current size through getHight on the LL. But supplyong it to the SV via changed LayoutParams does not work - of course, that would only change the height of the SV on the screen. Is there a way to put the changed height of the LL into the SV in the code, somehow? Question 3: I havn't tried it yet. Would creating the SV, LL and its children in code and then adding/removing children of changed size as required, make the SV adapt to the changes? And last question: Is there a better aüpproach, except using ListViews?

  • How to virtually delete data from multiple tables that are linked by a foreign key ?

    - by Shantanu Gupta
    I am using Sql Server 2005 This is a part of my database diagram. I want to perform deletion on my database which will start from tblDomain up tp tblSubTopics. Consider that each table has IsDeleted column which has to be marked true if request was made to delete data. But that data shoud remain their physically. Tables which will have IsDeleted Column are tblDomain tblSubject tblTopic tblSubTopic Now I want, if a user marks one domain as deleted then all the refrence field should also get marked as deleted. i.e. 1 domain is related to 5 subjects, those 5 subjects are related to 25 topics, those 25 topics are related to 500 subtopics and so on. Then how should i mark all these fileds as Deleted. ?

  • Starting an Intent to Launch an app to Background in Android

    - by Tista
    Hi all, I'm using Wikitude API 1.1 as an AR viewer in my application. The problem with Wikitude, if I haven't launched the actual Wikitude application since the phone's bootup, I will get a NullPointerException everytime I start my own application. So I figure if I can start my app first and them check if Wikitude is installed and or running. If it's not installed, go to market n download. If it's not running, then we should run it straight to background so that my app doesn't loose its focus. // Workaround for Wikitude this.WIKITUDE_PACKAGE_NAME = "com.wikitude"; PackageManager pacMan = Poligamy.this.getPackageManager(); try { PackageInfo pacInfo = pacMan.getPackageInfo(this.WIKITUDE_PACKAGE_NAME, pacMan.GET_SERVICES); Log.i("CheckWKTD", "Wikitude is Installed"); ActivityManager aMan = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE); List<RunningAppProcessInfo> runningApps = aMan.getRunningAppProcesses(); int numberOfApps = runningApps.size(); for(int i=0; i<numberOfApps; i++) { if(runningApps.get(i).processName.equals(this.WIKITUDE_PACKAGE_NAME)) { this.WIKITUDE_RUNNING = 1; Log.i("CheckWKTD", "Wikitude is Running"); } } if(this.WIKITUDE_RUNNING == 0) { Log.i("CheckWKTD", "Wikitude is NOT Running"); /*final Intent wIntent = new Intent(Intent.ACTION_MAIN, null); wIntent.addCategory(Intent.CATEGORY_LAUNCHER); final ComponentName cn = new ComponentName("com.wikitude", "com.mobilizy.wikitudepremium.initial.Splash"); wIntent.setComponent(cn); wIntent.setFlags(Intent.FLAG_ACTIVITY_NO_USER_ACTION); startActivityIfNeeded(wIntent, 0);*/ } } catch (NameNotFoundException e) { // TODO Auto-generated catch block Log.i("CheckWKTD", "Wikitude is NOT Installed"); e.printStackTrace(); //finish(); } The part I block commented is the intent to start Wikitude. But I always failed in restricting Wikitude to background. Any help? Thanks before. Best, Tista

  • How to detect OpenGL capabilities without creating a GLSurfaceView (Android)

    - by ADB
    I am trying to access the OpenGL capability of the phone before deciding whether to use OpenGL or Canvas for graphics puposes. However, all the functions that I can read documentation on requires you to already have a valid OpenGL context (namely, create a GLSurfaceView and assign it a rendered. Then check the OpenGL parameters in the onSurfaceCreated). So, is there a way to check the extensions, renderer name and max texture size capability of the phone BEFORE having to create any OpenGL views?

  • Animating translation and scaling of view in Android

    - by hgpc
    I have to animate a view from state A to B with changes to its scale, position and scrolling. I know everything about state A (widthA, heightA, topA, leftA, scrollXA, scrollYA) and state B (widthB, heightB, topB, leftB, scrollXB, scrollYB). So far I wrote the following code: AnimationSet animation = new AnimationSet(true); int toXDelta; // What goes here? int toYDelta; // What goes here? TranslateAnimation translateAnimation = new TranslateAnimation(1, toXDelta, 1, toYDelta); translateAnimation.setDuration(duration); animation.addAnimation(translateAnimation); float scale = (float) widthB / (float) widthA; ScaleAnimation scaleAnimation = new ScaleAnimation(1, scale, 1, scale); scaleAnimation.setDuration(duration); animation.addAnimation(scaleAnimation); animation.setAnimationListener(new AnimationListener() { @Override public void onAnimationEnd(Animation arg0) { view.clearAnimation(); // Change view to state B } @Override public void onAnimationRepeat(Animation arg0) {} @Override public void onAnimationStart(Animation arg0) {} }); view.startAnimation(animation); Is this the right way to do this? If so, how should I calculate the values of toXDelta and toYDelta? I'm having trouble finding the exact formula. Thanks!

  • Android - Read PNG image without alpha and decode as ARGB_8888

    - by loki666
    I try to read an image from sdcard (in emulator) and then create a Bitmap image with the BitmapFactory.decodeByteArray method. I set the options: options.inPrefferedConfig = Bitmap.Config.ARGB_8888 options.inDither = false Then I extract the pixels into a ByteBuffer. ByteBuffer buffer = ByteBuffer.allocateDirect(width*height*4) bitmap.copyPixelsToBuffer(buffer) I use this ByteBuffer then in the JNI to convert it into RGB format and want to calculate on it. But always I get false data - I test without modifying the ByteBuffer. Only thing I do is to put it into the native method into JNI. Then cast it into a unsigned char* and convert it back into a ByteBuffer before returning it back to Java. unsigned char* buffer = (unsinged char*)(env->GetDirectBufferAddress(byteBuffer)) jobject returnByteBuffer = env->NewDirectByteBuffer(buffer, length) Before displaying the image I get data back with bitmap.copyPixelsFromBuffer( buffer ) But then it has wrong data in it. My Question is if this is because the image is internally converted into RGB 565 or what is wrong here? ..... Have an answer for it: - yes, it is converted internally to RGB565. Does anybody know how to create such an bitmap image from PNG with ARGB8888 pixel format? If anybody has an idea, it would be great!

  • Merge two bytes in java/android

    - by Shane
    Hi, I have a frame of 22 bytes. The frame is the input stream from an accelerometer via bluetooth. The acceleromter readings are a 16 bit number split over two bytes. When i try to merge the bytes with buffer[1] + buffer[2], rather than adding the bytes, it just puts the results side by side. so 1+2 = 12. Could someone tell me how to combine these two bytes to obtain the original number. (btw the bytes are sent little endian) Thanks

  • Popup window size in android

    - by Bostjan
    I'm creating a popup window in a listactivity in the event onListItemClick. LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View pop = inflater.inflate(R.layout.popupcontact, null, false); ImageView atnot = (ImageView)pop.findViewById(R.id.aNot); height = pop.getMeasuredHeight(); width = pop.getMeasuredWidth(); Log.e("pw","height: "+String.valueOf(height)+", width: "+String.valueOf(width)); atnot.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { pw.dismiss(); } }); pw = new PopupWindow(pop, width, height, true); // The code below assumes that the root container has an id called 'main' //pw.showAtLocation(v, Gravity.CENTER, 0, 0); pw.showAsDropDown(v, 10, 5); Now, the height and width variables were supposed to be height and width of the layout used for the popup window (popupcontact). But they return 0. I guess that is because the layout isn't rendered yet. Does anyone have a clue, how can I control the size of the popup window without needing to use absolute pixel numbers?

  • Android: raise AlertDialog from background thread

    - by Stefan Klumpp
    In my activity there's some stuff going on in a background thread, which gets started in Activity_1. The processing of the background thread takes a while and I want to notify the user when it's completed via an AlertDialog. However, the user might have changed to Activity_2 or Activity_3 in the meantime and I would like to pop up the AlertDialog always in the current Activity. Any idea how to realize this?

I am trying to update the TextView of my Home screen widget but it seems that I cant access the TextView of my AppWidgetProvider on onReceive method. Here is a sample code of my onReceive public void onReceive(Context context,Intent intent) { final String action = intent.getAction(); if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else { if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) { String msg = "null"; try { msg = intent.getStringExtra("msg"); } catch (NullPointerException e) { } Toast.makeText(context, msg, Toast.LENGTH_SHORT).show(); // code for gathering the text to update the TextView } } super.onReceive(context, intent); }

  • How to use startMethodTracing APIs on Android?

    - by Rajorshi
    I have recently started working on an app which has both Java and native components. I am trying to generate trace information for both components using Debug.startMethodTracing("myapp") and Debug.startNativeTracing() alternately. However, both are behaving unexpectedly. When I use Debug.startMethodTracing("myapp"), I can see a file /sdcard/myapp.trace being created but it is always empty no matter how long I run my app. When I use Debug.startNativeTracing() and start the emulator with the -trace <tracename> switch, I see a message saying "Trace started", but when I try to run my app, the emulator crashes. Am I missing something obvious here? How do I debug this problem?

  • Android WebViewClient problem

    - by deSelby
    I've defined a private class that extends WebViewClient and set my WebView's client to an instance of that class (webView01.setWebViewClient(new Callback());). The class definition is as follows: private class Callback extends WebViewClient { public void onLoadResource (WebView view, String url) { } public void onPageStarted (WebView view, String url, Bitmap favicon) { } public void onPageFinished (WebView view, String url) { Animation anim = AnimationUtils.loadAnimation(MyNews.this, R.anim.webviewanim); view.startAnimation(anim); } public void onReceivedError (WebView view, int errorCode, String description, String failingUrl) { } public boolean shouldOverrideUrlLoading (WebView view, String url) { Log.e("loading url", url); return false; } } My problem is that onPageFinished is definitely getting called, but shouldOverrideUrlLoading is never being called. What am I doing wrong here?
