监听GPS开关切换(PROVIDERS_CHANGED_ACTION)

For an example, first add the following permission to your manifest: <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />Then, a simple Activity:public class MainActivity extends Activity{    private GpsStatusReceiver receiver = new GpsStatusReceiver();    @Override    public void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);    }    @Override    protected void onResume()    {        super.onResume();        registerReceiver(receiver, new IntentFilter(LocationManager.PROVIDERS_CHANGED_ACTION));    }    @Override    protected void onPause()    {        super.onPause();        unregisterReceiver(receiver);    }    private class GpsStatusReceiver extends BroadcastReceiver    {        @Override        public void onReceive(Context context, Intent intent)        {            LocationManager lm = (LocationManager) context.getSystemService(Service.LOCATION_SERVICE);            boolean isEnabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);            onGpsStatusChanged(isEnabled);        }    }    private void onGpsStatusChanged(boolean isEnabled)    {        // Do/start your work here.        Toast.makeText(this, "GPS enabled - " + isEnabled, 0).show();    }}
