次の問題があります。サーバーにいつでも座標を送信するプログラムが必要です。私はタスクマネージャーを作成し、座標を送信することができます。
これは私のコードです。私の問題はどうですか?
私のメインアクティビティ:
public class MainActivity extends Activity {
public int ingreso =0;
double latitud=0;
double longitud=0;
boolean isGPSEnabled = false;
boolean isNetworkEnabled = false;
public double lat1=0;
public double lon1=0;enter code here
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final InstallationId Miid = new InstallationId();
Alarmas mUIUpdater = new Alarmas(new Runnable() {
@Override
public void run() {
// do stuff ...
/* Use the LocationManager class to obtain GPS locations */
LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener mlocListener = new MyLocationListener();
isGPSEnabled = mlocManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
isNetworkEnabled = mlocManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled )
{
/*NO HAY GPS*/
Toast.makeText( getApplicationContext(),"El GPS se encuentra desactivado. Favor activarlo para determinar el Centro de embellecimiento mas cercano",Toast.LENGTH_LONG ).show();
Intent intentRedirectionGPSSettings = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
intentRedirectionGPSSettings.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivityForResult(intentRedirectionGPSSettings, 0);
}
else
{
if (isGPSEnabled)
{
mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
}
else
{
if (isNetworkEnabled)
{
mlocManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, 0, 0, mlocListener);
}
}
}
lat1=((MyLocationListener) mlocListener).GetLatitud();
Log.d("Enviando datos", "es " + ((MyLocationListener) mlocListener).GetLatitud());
lon1=((MyLocationListener) mlocListener).GetLongitud();
String miurl="http://casoft.com.co/evvc/registro.php?idphone=" + Miid.id(getApplicationContext()) + "&lat1=" + lat1 + "&lon1=" + lon1;
new Tareas().execute(miurl);
mlocManager.removeUpdates(mlocListener);
}
});
mUIUpdater.startUpdates();
//new Tareas().execute("http://casoft.com.co/evvc/registro.php?idphone=1&lat1=1&lon1=2");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
public class MyLocationListener implements LocationListener
{
@Override
public void onLocationChanged(Location loc)
{
loc.getLatitude();
loc.getLongitude();
latitud = loc.getLatitude();
longitud= loc.getLongitude();
Log.d("Enviando datos", latitud + "es " + longitud);
}
@Override
public void onProviderDisabled(String provider)
{
ingreso=0;
}
@Override
public void onProviderEnabled(String provider)
{
Toast.makeText( getApplicationContext(),"Gps Enabled",Toast.LENGTH_SHORT).show();
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras)
{
}
public double GetLatitud()
{
return latitud;
}
public double GetLongitud()
{
return longitud;
}
}/* End of Class MyLocationListener */
public void Sael(View view) {
Intent i = new Intent(this, navegador.class );
startActivity(i);
}
}
これはidphoneを取得するためのものです:
public class InstallationId {
private static String sID = null;
private static final String INSTALLATION = "INSTALLATION";
public synchronized static String id(Context context) {
if (sID == null) {
File installation = new File(context.getFilesDir(), INSTALLATION);
try {
if (!installation.exists())
writeInstallationFile(installation);
sID = readInstallationFile(installation);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
return sID;
}
private static String readInstallationFile(File installation) throws IOException {
RandomAccessFile f = new RandomAccessFile(installation, "r");
byte[] bytes = new byte[(int) f.length()];
f.readFully(bytes);
f.close();
return new String(bytes);
}
private static void writeInstallationFile(File installation) throws IOException {
FileOutputStream out = new FileOutputStream(installation);
String id = UUID.randomUUID().toString();
out.write(id.getBytes());
out.close();
}
}
そして、これはアラームです:
public class Alarmas {
private Handler mHandler = new Handler(); // TODO Don't know if this is created in the UI thread
private Runnable mStatusChecker;
private int UPDATE_INTERVAL = 9000;
/**
* Creates an UIUpdater object, that can be used to
* perform UIUpdates on a specified time interval.
*
* @param uiUpdater A runnable containing the update routine.
*/
public Alarmas(final Runnable uiUpdater){
mStatusChecker = new Runnable() {
@Override
public void run() {
// Run the passed runnable
uiUpdater.run();
// Re-run it after the update interval
mHandler.postDelayed(this, UPDATE_INTERVAL);
}
};
}
/**
* The same as the default constructor, but specifying the
* intended update interval.
*
* @param uiUpdater A runnable containing the update routine.
* @param interval The interval over which the routine
* should run (milliseconds).
*/
public Alarmas(Runnable uiUpdater, int interval){
this(uiUpdater);
UPDATE_INTERVAL = interval;
}
/**
* Starts the periodical update routine (mStatusChecker
* adds the callback to the handler).
*/
public void startUpdates(){
mStatusChecker.run();
}
/**
* Stops the periodical update routine from running,
* by removing the callback.
*/
public void stopUpdates(){
mHandler.removeCallbacks(mStatusChecker);
}
}
そして、これがTASKです
class Tareas extends AsyncTask<String, String, String>{
@Override
protected String doInBackground(String... uri) {
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response;
String responseString = null;
Log.d("Enviando datos", "Solicitando");
try {
response = httpclient.execute(new HttpGet(uri[0]));
StatusLine statusLine = response.getStatusLine();
if(statusLine.getStatusCode() == HttpStatus.SC_OK){
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.getEntity().writeTo(out);
out.close();
responseString = out.toString();
} else{
//Closes the connection.
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
} catch (ClientProtocolException e) {
//TODO Handle problems..
} catch (IOException e) {
//TODO Handle problems..
}
return responseString;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
//Do anything with response..
}
}
ご協力いただきありがとうございます。
Pda: 私はこのプログラムが必要です。いつでも動作し、いつでも GPS レポートを送信してください。テストでは、UPDATE_INTERVAL が 9 秒あります。
