Hinzufügen Ich bilde eine App, die Google Maps aus einem bestimmten Grund verwendet. Also habe ich eine Google Maps-App in Android Studio und ich bekam eine Tätigkeit, die FragmentActivity erstreckt. Alles funktioniert perfekt, aber jetzt möchte ich die Aktionsleiste am oberen Bildschirmrand hinzufügen. Das Problem ist, dass die Karte den ganzen Bildschirm nimmt, und ich weiß nicht, wie es zu behebenActionBar zu FragmentActivity
Hier ist mein Code für die Aktivität ist:
public class MainActivity extends FragmentActivity implements LocationListener {
private GoogleMap mMap; // Might be null if Google Play services APK is not available.
double lon = 0;
double lat = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setUpMapIfNeeded();
}
@Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
}
public void showSettingsAlert(){
AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);
// Setting Dialog Title
alertDialog.setTitle("GPS settings");
// Setting Dialog Message
alertDialog.setMessage("GPS is not enabled. Do you want to go to settings menu?");
// On pressing Settings button
alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
});
// on pressing cancel button
alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
// Showing Alert Message
alertDialog.show();
}
private void setUpMapIfNeeded() {
LocationManager manager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
/*if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
showSettingsAlert();
}
else{*/
// Getting Google Play availability status
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
// Showing status
if(status!=ConnectionResult.SUCCESS){ // Google Play Services are not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();
}else { // Google Play Services are available
// Getting reference to the SupportMapFragment of activity_menu.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting mMap object from the fragment
mMap = fm.getMap();
// Enabling MyLocation Layer of Google Map
mMap.setMyLocationEnabled(true);
// Getting LocationManager object from System Service LOCATION_SERVICE
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
boolean networkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if(networkEnabled){
Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if(location!=null){
lon = location.getLongitude();
lat = location.getLatitude();
LatLng latLng = new LatLng(lat, lon);
// Showing the current location in Google Map
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
// Zoom in the Google Map
mMap.animateCamera(CameraUpdateFactory.zoomTo(15));
}
}
// Creating a criteria object to retrieve provider
Criteria criteria = new Criteria();
// Getting the name of the best provider
String provider = locationManager.getBestProvider(criteria, true);
// Getting Current Location
Location location = locationManager.getLastKnownLocation(provider);
if(location!=null){
onLocationChanged(location);
}
locationManager.requestLocationUpdates(provider, 20000, 0, this);
/*}*/}
}
@Override
public void onLocationChanged(Location location) {
double latitude = location.getLatitude();
// Getting longitude of the current location
double longitude = location.getLongitude();
// Creating a LatLng object for the current location
LatLng latLng = new LatLng(latitude, longitude);
// Showing the current location in Google Map
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
// Zoom in the Google Map
mMap.animateCamera(CameraUpdateFactory.zoomTo(15));
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
@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_menu, menu);
super.onCreateOptionsMenu(menu);
return true;
}
dies mein Layout für die Aktivität ist (vielleicht die es Problem):
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/map"
tools:context=".MainActivity"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
