That's a lot of code... no time to read it over now.. but off the top of my head: look into either using a database, an Application class (that will run the whole time your app is alive), or adding extras to the Intent bundle before starting your subactivity. These are all methods to pass data around between activities.

I am creating an application which requires login and enables user to configure some settings.
However I would like to enable user to store preferred settings, username and password.
Does anyone know how to store and retrieve values from registry? Another possibility is using SQL Lite database but if possible I would prefer to store values to registry.
Is it possible to store strings values in multiple files? Eg, strings.xml, strings1.xml, strings2.xml etc.
I do not mean localized versions of the same file - those multiple files should contain different string ids in the same language, so in code they would be refered like: R.strings1.my_string_1 R.strings1.my_string_2 R.strings2.my_string_3 etc. So, "strings1", "strings2", "strings3" would be a kind of namespace for them.
Or, another way is to have multiple R classes inside one project, which would deal with different stringsXXX.xml files.
Like, currently we can refer to "my.name.space.R" and to "android.R" at the same time, so is it possible to have: android.R my.name.space1.R my.name.space2.R etc
At the same time inside single project?
Currently, I'm using the following code across all of my activities in my app to store application level variables and carry values between activities..
prefs = this.getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
I didn't have a PreferenceActivity prior to this, but now I do and I am looking to store a few user prefs from this new PreferenceActivity in the same sharedPreferences tag, "MyPrefs".
I know I can access the PreferenceActivity SharedPrefs from my activities via
prefs = PreferenceManager.getDefaultSharedPreferences(this);
but I would like those values saved to my current sharedPreferences tag, "MyPrefs", but I'm not sure how to do this.
I'm kinda noob to android so please bear with me. I'm currently developing app which uses tabs. My question now is: how to store values of variables so I can access them on the other tabs? I want to create something similar to sessions in PHP where I can save variables on one page and access on the other.

View 2 Replies View RelatedI have a collection of strings and declared the strings individually as arrays using ArrayList<String> al=new ArrayList<String>(); and called the arrays in the program by using al=getIntent().getStringArrayListExtra("titles");

public class SongsArray {

Would using a regular expression commit a huge sin? ;-) The xml isn't that big...

View 1 Replies View RelatedI have searched and searched and I just can't get this code to work. I have a main.xml layout and a setting.xml. I have some values I would like the Settings.class to change in my main apps class.Three string to be exact. I have tried this simple test code in my main app class.
settings.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), Settings.class);
startActivityForResult(intent, 0);}});
//Then a function
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent){
super.onActivityResult(requestCode, resultCode, intent);
Bundle extras = intent.getExtras();
String value = extras.getString("myKey");
if(value!=null){
Log.d("hmmm",value);}}}
In my settings.class I have the following
returnHome.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.putExtra("myKey", "YEAH");
setResult(RESULT_OK, intent);
finish();}});
Back in main app class it is not getting logged. Like I said I have three string in the main class that I want settings class to change and send back.
I have an app which makes use of several layout-views. Every layout - view also got a class for it, which extend the Activity class. One class for example retrieves some database values whilst offering a search form to the user. Afterwards the user can select one of those values and he gets presented with another screen which gives similar options as the one selected. Anyways, I'd like for the first Activity to be able to send an array with data (Strings for example) to the second one. Right now I show an activity by using:
Intent i = new Intent(this, activitysName.class); startActivity(i);
I have no idea whilst using this construction how I can "initialize" the new object with the String array I want to pass to it. So how should this be achieved ? Should I be using something else instead of an Intent-Activity combination ?
I do not know the reason why am i getting same values of different JSON date values. Here is my code for parsing date values in JSON date format:

public class JSONDateParsing extends Activity {/** Called when the activity is first created. */String myString;
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = new TextView(this);
//Date d = (new Date(1266029455L));
//Date d = (new Date(1266312467L));
Date d = (new Date(1266036226L));
//String s = d.getDate() + "-" + d.getMonth() + "-" + d.getYear() + d.getHours() +
d.getMinutes() + d.getSeconds();
// SimpleDateFormat sdf=new SimpleDateFormat("yyyy MMM dd @ hh:mm aa"); //Toast.makeText(this, d.toString(), Toast.LENGTH_SHORT);
Log.e("Value:", d.toString());
myString = d.toString();
String []words = myString.split(" ");
for(int i = 0;i < words.length; i++)
Log.e("Value:", words[i]);
myString = words[2] + "-" + words[1] + "-" + words[5] + " " + words[3];
tv.setText(myString);
setContentView(tv);
} }
Hello everyone, and thanks in advance for the help. What I'm trying to do is a relatively simple task, but one that doesn't seem to be working. What I'm trying to do is display the Orientation X,Y,Z coordinates on the screen in basic TextView boxes. The sensors are constantly updating my Global.myOrientation float array, and then I'm running a Timed thread (I'm very new to threading, so forgive me if it's ugly, but it gets the job done almost). In this thread I just set the value of each TextView's text to the desired value. The problem is that it only seems to work the first time.
It correctly displays whatever my initial data is, but then subsequent runs of the thread do nothign to update the onscreen values when I change the orientation of the phone. LogCat output shows me that inside the run() method, the values of Global.getOrientationX,Y,Z are being updated correctly, and that the right data is being passed to TextView. How can I get around this limitation of TextView being initialized once and then immutable?
Any assistance in fixing this, or providing an alternate solution would be greatly appreciated. Code posted below:

I have trouble (example<http://groups.google.com/group/android-developers/browse_thread/threa...>) wrapping my head around styles/themes. Can somebody help me or point me to actual documentation?
Let's say I have a drawable that I want to use as the background of a layout:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle>
<gradient android:startColor="#9F9FA4" android:endColor="#66FFFFFF" android:angle="270" /> </shape>
Now I want to have a dark and a light theme. Depending on the chosen theme I want to have a different value for startColor and endColor. How do I do that? I am aware of extending themes, but what do I put into the items? How do I reference those new values then?
I am experimenting with orientation sensor, register it like this: SesnorManager sensor_manager = (SensorManager)getSystemService (Context.SENSOR_SERVICE); Sensor sensor_orientation = sensor_manager.getSensorList (SensorManager.SENSOR_ORIENTATION).get(0); sensor_manager.register Listener(sensor_listener, sensor_orientation, SensorManager.SENSOR_DELAY_UI); and then read the orientation values in the sensor event listener: private final SensorEventListener sensor_listener = new SensorEventListener() { ... float sensor_data_x = event.values[SensorManager.DATA_X];}

View 1 Replies View RelatedI am setting multiple alarms like this, with different values of id. Multiple calls to AlarmManager.setRepeating deliver the same Intent/PendingIntent extra values, but I supplied different ones.
AlarmManager alarms = (AlarmManager)context.getSystemService(
Context.ALARM_SERVICE); Intent i = new Intent(MyReceiver.ACTION_ALARM);
// "com.example.ALARM" i.putExtra(MyReceiver.EXTRA_ID, id);
// "com.example.ID", 2 PendingIntent p = PendingIntent.getBroadcast(context, 0, i, 0);
alarms.setRepeating(AlarmManager.RTC_WAKEUP, nextMillis, 300000, p); // 5 mins
And receiving them like this:
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_ALARM)) {
// It's time to sound/show an alarm
final long id = intent.getLongExtra(EXTRA_ID, -1);
The alarm is delivered to my receiver at the right times, but often with EXTRA_ID set to the wrong value: it's a value that I have used at some point, just not the one that I wanted delivered at that particular time.
I have a marker on the map using an Overlay. I also have access to the compass sensor which I'm able to show a textView with the orientation values (0 to 359). How can I apply this values to the marker? (which is a drawable). I already have a MAtrix created but when I insert the orientation value gives me an error, here it is:
GeoPoint geopoint = new GeoPoint((int) (newLocation.getLatitude() * 1E6),
(int) (newLocation.getLongitude() * 1E6)); Paint paint = new Paint();
Point pt = new Point(); mapView.getProjection().toPixels(geopoint, pt);
Bitmap bmp = BitmapFactory.decodeResource(getResources(),R.drawable.user2);
Matrix matrix = new Matrix(); matrix.postTranslate(-25, -25);
matrix.postRotate(direction); matrix.postTranslate(pt.x, pt.y);
paint.setAntiAlias(true); paint.setFilterBitmap(true);
int width = bmp.getWidth(); int height = bmp.getHeight();
Bitmap changedBitmap = Bitmap.createBitmap(bmp, 0, 0, width, height, matrix, true);
BitmapDrawable icon = new BitmapDrawable(changedBitmap);
icon.setBounds(0, 0, icon.getIntrinsicWidth(), icon.getIntrinsicHeight());
userOverlay useroverlay = new userOverlay(icon); useroverlay.addItem(item);
mapView.getOverlays().add(useroverlay);
I used the value retrieved from the sensor on "direction" but it doesn't work.
