Это мое первое занятие, и всякий раз, когда я пытаюсь передать удвоенные значения "широта и долгота", используя Intent, происходит сбой приложения, я не знаю, что еще делать.
Я видел, что если я не добавлю startActivity (Intent) ii, то не сделаю sh.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//
requestPermission();
//
client = LocationServices.getFusedLocationProviderClient(this);
Button button = findViewById(R.id.getLocation);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(ActivityCompat.checkSelfPermission(MainActivity.this, ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED){
return;
}
client.getLastLocation().addOnSuccessListener(MainActivity.this, new OnSuccessListener<Location>() {
@Override
public void onSuccess(Location location) {
if (location != null) {
TextView textView = findViewById(R.id.location);
textView.setText(location.toString());
}
double latitude = location.getLatitude();
double longitude = location.getLongitude();
Intent intent = new Intent(getApplicationContext(), MapsActivity.class);
intent.putExtra("Lat",latitude);
intent.putExtra("Lon",longitude);
startActivity(intent);
}
});
}
});
Это еще одно занятие
надеюсь, оно поможет найти ошибка, я не знаю, почему эта строка может вызвать такое большое число
спасибо в advaced
