GPsStatus在GPS_EVENT_STARTED和GPS_EVENT_STOPPED之间的切换
GPsStatus在GPS_EVENT_STARTED和GPS_EVENT_STOPPED之间的切换
提问于 2014-07-17 13:16:09
我有一些问题，以检测GPS开关，打开/关闭。
我可以检测到GPS的开关，但Toasts总是在我的屏幕上画。我已经启用了全球定位系统
“全球定位系统失灵”
“全球定位系统启用”
“全球定位系统失灵”
“全球定位系统启用”
“全球定位系统失灵”
“启用GPS”..。
这是我的密码：
final LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
locationManager.addGpsStatusListener(new GpsStatus.Listener() {
@Override
public void onGpsStatusChanged(int event) {
switch (event) {
case GpsStatus.GPS_EVENT_STARTED:
Toast.makeText(HomeActivity.this, "GPS enabled", Toast.LENGTH_LONG).show();
currentLocation = getLocation();
if (currentLocation != null) setUpMapIfNeeded();
break;
case GpsStatus.GPS_EVENT_STOPPED:
Toast.makeText(HomeActivity.this, "GPS disabled", Toast.LENGTH_LONG).show();
break;
default:
}
}

我在活动中注册了一个接收器，运气好得多。BroadcastReceiver对我来说完美无缺。
private static final String ACTION_GPS = "android.location.PROVIDERS_CHANGED";
private BroadcastReceiver yourReceiver;
@Override
public void onStop() {
super.onStop();
// Do not forget to unregister the receiver!!!
if (yourReceiver != null) {
unregisterReceiver(yourReceiver);
yourReceiver = null;
}
@Override
public void onResume() {
super.onResume();
registerReceiverGPS();
private void registerReceiverGPS() {
if (yourReceiver == null) {
// INTENT FILTER FOR GPS MONITORING
final IntentFilter theFilter = new IntentFilter();
theFilter.addAction(ACTION_GPS);
yourReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent != null) {
String s = intent.getAction();
if (s != null) {
if (s.equals(ACTION_GPS)) {
checkGPS();
}
}
}
}
};
registerReceiver(yourReceiver, theFilter);
}
}
private void checkGPS() {
Context context = this.getApplicationContext();
if (context != null) {
Button btnGPS = (Button) findViewById(R.id.btnGPS);
if (btnGPS != null) {
LocationManager locationManager = (LocationManager) context
.getSystemService(Context.LOCATION_SERVICE);
boolean b = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
locationManager = null;
if (b) {
if (btnGPS.getVisibility() != View.GONE) {
btnGPS.setVisibility(View.GONE);
}
} else {
if (btnGPS.getVisibility() != View.VISIBLE) {
btnGPS.setVisibility(View.VISIBLE);
}
}
}
}
