Java GPsStatus在GPS_事件_启动和GPS_事件_停止之间切换
我在检测GPS开关打开/关闭时遇到一些问题 我可以检测到GPS开关打开,但祝酒词总是在我的屏幕上。 我启用了“GPS” “GPS禁用” “启用GPS” “GPS禁用” “启用GPS” “GPS禁用” “启用GPS” 这是我的代码:Java GPsStatus在GPS_事件_启动和GPS_事件_停止之间切换,java,android,google-maps,gps,Java,Android,Google Maps,Gps,我在检测GPS开关打开/关闭时遇到一些问题 我可以检测到GPS开关打开,但祝酒词总是在我的屏幕上。 我启用了“GPS” “GPS禁用” “启用GPS” “GPS禁用” “启用GPS” “GPS禁用” “启用GPS” 这是我的代码: final LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); locationManager.ad

我只是在活动中注册了一个接收者,运气要好得多。广播接收器为我工作得完美无缺
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);
}
}
}
}
}
我使用GPSstatuslistener获取卫星的数量。我创建一个广播接收器来检查GPS是否启用或禁用。它起作用了。Thx:)
