Select the image onclick and apply seekbar resize to it

In my app i have to apply resize using seekbar to selected image onclick but problem is that only last applied stickerview can be resized and if i want to resize the previous stickerview then also last sticker is being resized.
Can anyone help me with this problem
holder.icon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (a == 1) {
canvas.setBackgroundResource(mThumbIds[position]);
dialog.dismiss();
a = 0;
}
if (a1 == 1) {
Gallery gallery = (Gallery) findViewById(R.id.gallery);
gallery.setSpacing(1);
final GalleryImageAdapter galleryImageAdapter= new GalleryImageAdapter(getApplicationContext(),position);
gallery.setAdapter(galleryImageAdapter);
gallery.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
iv_sticker1 = new StickerImageView(MainActivity2.this);
if(x ==1)
iv_sticker1.setImageResource(galleryImageAdapter.mImageIds[position]);
if(x ==2)
iv_sticker1.setImageResource(galleryImageAdapter.mImageIds1[position]);
if(x ==3)
iv_sticker1.setImageResource(galleryImageAdapter.mImageIds2[position]);
canvas.addView(iv_sticker1);
}
});
a1 = 0;
}
if (a2 == 1) {
iv_sticker1 = new StickerImageView(MainActivity2.this);
iv_sticker1.setImageDrawable(getResources().getDrawable(mThumbIds2[position]));
canvas.addView(iv_sticker1);
iv_sticker1.setOwnerId(2);
dialog.dismiss();
a2 = 0;
}
if (a3 == 1) {
iv_sticker1 = new StickerImageView(MainActivity2.this);
iv_sticker1.setImageDrawable(getResources().getDrawable(mThumbIds3[position]));
canvas.addView(iv_sticker1);
dialog.dismiss();
a3 = 0;
}
}
});
And this is my resize program
final SeekBar sk1 = (SeekBar) findViewById(R.id.seekBar1);
sk1.setMax(500);
sk1.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
// TODO Auto-generated method stub
iv_sticker1.getMainView();
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(progress, progress);
iv_sticker1.setLayoutParams(params);
iv_sticker1.setMinimumWidth(progress);
iv_sticker1.setMinimumHeight(progress);
}
});
Now whenever i do this only last iv_sticker1 get selected.How can i apply resize to selected image on click?

Pausing an Animation does not work properly

I am working on a game. Its all working well, the only thing I need is for my animation to pause when I press the home or on/off button on my phone. As far as I log correct, the pause script (as found here) works well. It keeps incrementing the time and applies it to the animation. However when I resume my game, the animations all resume on the left side of the screen instead of the position it originally was in when I paused it in. This is my stripped code. I really hope someone can help me.
public class GameView extends Activity{
ImageView peanut;
TranslateAnim movePeanut;
AnimationSet animSet = new AnimationSet(true);

Android: How can i make my googleapp run in the background

How can i make this app run in the background? I can't implement Service class because i already using MapActivity. What should i do?
public class GoogleMaps extends MapActivity implements LocationListener {
LocationManager locationManager;
MapView map;
long start;
long stop;
MyLocationOverlay myLocation;
MapController controller;
List<Overlay> overlayList;
int x, y;
GeoPoint touchedPoint;
Drawable d;
String towers;
int lat;
int longi;
double midllat;
double midlongi;
NotificationManager nm;
static final int uniqueID = 1394885;
// Location location;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.googlemaps);
map = (MapView) findViewById(R.id.mvGoogleMaps);
ourLocation();
Touchy t = new Touchy();
overlayList = map.getOverlays();
overlayList.add(t);
d = getResources().getDrawable(R.drawable.round_pointer);
controller.setZoom(18);
Criteria crit = new Criteria();
towers = locationManager.getBestProvider(crit, false);
Location location = locationManager.getLastKnownLocation(towers);
nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm.cancel(uniqueID);
}
public void ourLocation()
{
// Pin der blinker på lokation
myLocation = new MyLocationOverlay(this, map);
map.getOverlays().add(myLocation);
myLocation.enableMyLocation();
// Fin nuværende lokation
locationManager = (LocationManager) this
.getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
20000, 0, this);
controller = map.getController();
}
There is more code here, but nothing relevant to this case. Just a feature that lets me pin a point.
#Override

controller.setZoom(18);
// Trying to get MyPostion.
Location myLocation = new Location("point A");
myLocation.setLongitude(location1.getLongitude());
myLocation.setLatitude(location1.getLatitude());
Location locationB = new Location("point B");
locationB.setLatitude(midllat);
locationB.setLongitude(midlongi);
float distance = myLocation.distanceTo(locationB);
if (distance < 100) {
String hej = formatDist(distance);
AudioManager am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
Intent intent = new Intent(this, GoogleMaps.class);

String body = "You are now in the silentzone";
String title = "IRemember";
Notification n = new Notification(R.drawable.round_pointer, body,
System.currentTimeMillis());
n.setLatestEventInfo(this, title, body, pi);
n.defaults = Notification.DEFAULT_ALL;
nm.notify(uniqueID, n);
}
}
public String formatDist(float meters) {
if (meters < 1000) {

Previous Marker also gets showed up if I change the location second time

I am currently showing marker on my current location whenever the current location gets changed. And the below code works fine. But the problem with this is,- Suppose for the first time I passed some location and my marker will be there at that position but the second time if I pass any other different location then my marker will be there in second location but at the same time my marker also stays in First Location too and I don't want this thing. I only need whenever the Current Location changes all other marker should gets disappeared, only the current location marker should be there. Hope I am clear to everyone
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mapView = (MapView) findViewById(R.id.mapView);
mapView.setBuiltInZoomControls(true);
mapController = mapView.getController();
mapController.setZoom(15);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
0, new GeoUpdateHandler());
}
public class GeoUpdateHandler implements LocationListener {
#Override
public void onLocationChanged(Location location) {
int lat = (int) (location.getLatitude() * 1E6);
int lng = (int) (location.getLongitude() * 1E6);
Drawable marker=getResources().getDrawable(android.R.drawable.star_big_on);
int markerWidth = marker.getIntrinsicWidth();
int markerHeight = marker.getIntrinsicHeight();
marker.setBounds(0, markerHeight, markerWidth, 0);
myItemizedOverlay = new MyItemizedOverlay(marker);
mapView.getOverlays().add(myItemizedOverlay);
GeoPoint point = new GeoPoint(lat, lng);
myItemizedOverlay.addItem(point, "myPoint1", "myPoint1");
mapController.animateTo(point);
String address = ConvertPointToLocation(point);
Toast.makeText(getBaseContext(), address, Toast.LENGTH_SHORT).show();
mapView.invalidate();
}
}
Below is my ItemizedOverlay class-
public class MyItemizedOverlay extends ItemizedOverlay<OverlayItem>{
private ArrayList<OverlayItem> overlayItemList = new ArrayList<OverlayItem>();
public MyItemizedOverlay(Drawable marker) {
super(boundCenterBottom(marker));
// TODO Auto-generated constructor stub
populate();
}
public void addItem(GeoPoint p, String title, String snippet){
OverlayItem newItem = new OverlayItem(p, title, snippet);
overlayItemList.add(newItem);
populate();
}
#Override
protected OverlayItem createItem(int i) {
// TODO Auto-generated method stub
return overlayItemList.get(i);
}
#Override
public int size() {
// TODO Auto-generated method stub
return overlayItemList.size();
}
public void clear() {
overlayItemList.clear();
populate();
}
#Override
public void draw(Canvas canvas, MapView mapView, boolean shadow) {
// TODO Auto-generated method stub
super.draw(canvas, mapView, shadow);
//boundCenterBottom(marker);
}
}

you just have to remove previously added items before adding the new one
public void addItem(GeoPoint p, String title, String snippet){
OverlayItem newItem = new OverlayItem(p, title, snippet);
overlayItemList.removeAll();
overlayItemList.add(newItem);
populate();
}

Positing user current location and show it in Google maps

I am developing an android application that contains 3 activities and one of them is map. I am using google maps
what I want:
When the user opens the activity (map) it shows the user her location not the coordinate.
The user should also be able to posit(pining) any place by using a pin and my app must store the coordinates for this pin in a variable so i can use it later.
public class LActivity extends MapActivity
{
/** Called when the activity is first created. */
MapView mapView;
GeoPoint geo;
MapController mapController;
LocationManager locationManager;
CustomPinpoint itemizedoverlay;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mapView = (MapView) findViewById(R.id.mapView);
// create a map view
//LinearLayout linearLayout = (LinearLayout) findViewById(R.id.main);
mapView.setBuiltInZoomControls(true);
// Either satellite or 2d
mapView.setSatellite(true);
mapController = mapView.getController();
mapController.setZoom(14); // Zoon 1 is world view
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, new GeoUpdateHandler());
Drawable drawable = this.getResources().getDrawable(R.drawable.point);
itemizedoverlay = new CustomPinpoint(drawable);
createMarker();
}
public class GeoUpdateHandler implements LocationListener {
#Override
public void onLocationChanged(Location location) {
int lat = (int) (location.getLatitude() * 1E6);
int lng = (int) (location.getLongitude() * 1E6);
GeoPoint point = new GeoPoint(lat, lng);
createMarker();
mapController.animateTo(point); // mapController.setCenter(point);
}
#Override
public void onProviderDisabled(String provider) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
}
private void createMarker() {
GeoPoint p = mapView.getMapCenter();
OverlayItem overlayitem = new OverlayItem(p, "", "");
itemizedoverlay.addOverlay(overlayitem);
mapView.getOverlays().add(itemizedoverlay);
}
#Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
this is CustomPinpoint class
public class CustomPinpoint extends ItemizedOverlay<OverlayItem> {
static int maxNum = 3;
OverlayItem overlays[] = new OverlayItem[maxNum];
int index = 0;
boolean full = false;
CustomPinpoint itemizedoverlay;
public CustomPinpoint(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
}
#Override
protected OverlayItem createItem(int i) {
return overlays[i];
}
#Override
public int size() {
if (full) {
return overlays.length;
} else {
return index;
}
}
public void addOverlay(OverlayItem overlay) {
if (index < maxNum) {
overlays[index] = overlay;
} else {
index = 0;
full = true;
overlays[index] = overlay;
}
index++;
populate();
}
}

I have implemented the same thing you want. I am providing you the sample code. In this I have also implemented the ProgressDialog when fetching the location.
This is the starting point for getting the location. I named this AndroidLocationActivity. This is the 1st activity which starts when your app starts.
String provider;
public double latitude, longitude = 0;
CurrentPositionTask getCurrentLocation;
Location currentLocation;
LocationListener locationListener;
LocationManager locationManager;
private long time=0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
setCriteria();
currentLocation = AndroidLocationActivity.this.locationManager.getLastKnownLocation(provider);
if (currentLocation == null) {
currentLocation = new Location(provider);
}
time = currentLocation.getTime();
if (latitude == 0 && longitude == 0) {
latitude = currentLocation.getLatitude();
longitude = currentLocation.getLongitude();
}
Toast.makeText(AndroidLocationActivity.this, String.valueOf(time), Toast.LENGTH_LONG).show();
Here set the time if time is not more than 1minute than i am not updating the location.
if (time >= 100000) {
latitude = 0;
longitude = 0;
}

Hope this will help.....

Remove your method onCreate and add this code:
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
initMap(); // This is the method which initialize the map
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
0, new GeoUpdateHandler());
Drawable drawable = this.getResources().getDrawable(R.drawable.point);
itemizedoverlay = new CustomPinpoint(drawable);
createMarker();
}
#Override
public void onResume()
{
super.onResume();
try
{
initMyLocation();
}catch(Exception e){}
}
/**
* Inits the map.
*/
protected void initMap()
{
mapView = (MyMapView) findViewById(R.id.mapView);
mapView.setBuiltInZoomControls(true);
mapView.setSatellite(true);
mapView.setStreetView(false);
mapController = mapView.getController();
mapOverlay = new MapOverlay();
List<Overlay> overlays = mapView.getOverlays();
overlays.add(mapOverlay);
mapController.setZoom(14);
mapView.invalidate();
}
/**
* Initialises the MyLocationOverlay and adds it to the overlays of the map.
*/
public void initMyLocation() {
try
{
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Location l = LocationService.getLastKnownLocation(lm);
int lat = (int)(l.getLatitude()*1E6);
int lng = (int)(l.getLongitude()*1E6);
mapController.setCenter(new GeoPoint(lat , lng));
myLocOverlay = new MyLocationOverlay(this, mapView);
myLocOverlay.enableMyLocation();
mapView.getOverlays().add(myLocOverlay);
mapController.setCenter(myLocOverlay.getMyLocation());
}catch(NullPointerException e){}
findMe();
}
/**
* This method will animate to my current position
*/
public void findMe()
{
try
{
mapController.animateTo(myLocOverlay.getMyLocation());
}catch(NullPointerException e){}
}
Then to store the Overlays for future use you can either use SharedPreferences or SQLite. There are loads of tutorials for each of them.
