我有問題加載谷歌地圖在我的片段。一切都開始在launchs活動 「ViatgeDetallViewActivity」 回收者視圖適配器:谷歌地圖在片段android
Context context = mActivity.getApplicationContext();
Intent intent = new Intent(context, ViatgeDetallViewActivity.class);
holder.mViatge.getId());
intent.putExtra("desc",p.getDesc());
intent.putExtra("location",p.getLocation());
mActivity.startActivityForResult(intent,ACTIVITY_View);
這是我DetallViewActivity:
public class ViatgeDetallViewActivity extends AppCompatActivity {
ViatgeDetallViewFragment fragment;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view);
Bundle extras = getIntent().getExtras();
if(extras != null)
{
String s = getIntent().getStringExtra("desc");
Location l = getIntent().getParcelableExtra("location");
Log.d("myTag", "estoy en el oncreate de detallviewActivity pasando pro extras" + s);
}
fragment = new ViatgeDetallViewFragment();
getSupportFragmentManager().beginTransaction()
.add(R.id.activity_fragment_view, fragment)
.commit();
getFragmentManager().beginTransaction().add(R.id.activity_fragment_view, fragment).commit();
}
}
隨着我ViatgeDetallViewFragment之中:
public class ViatgeDetallViewFragment extends Fragment implements OnMapReadyCallback {
private GoogleMap mMap;
private Marker mMarcadorActual;
public ViatgeDetallViewFragment() {
}
....
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_view, container, false);
SupportMapFragment mapFragment =
(SupportMapFragment)
getChildFragmentManager().findFragmentById(R.id.fragment_view_map);
mapFragment.getMapAsync(this);
return rootView;
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
//ask for permissions..
mMap.setMyLocationEnabled(true);
LatLng sydney = new LatLng(-34, 151);
mMarcadorActual = mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
}
隨着佈局是,Activity_view:
<Linear ...
<android.support.v7.widget.Toolbar
android:id="@+id/tlbMenuView"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
/>
<FrameLayout
android:id="@+id/activity_fragment_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
fragment_view:
<LinearLayout android:id="@+id/layout_fragment_view" xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
>
..
<fragment
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/fragment_view_map"
class="com.google.android.gms.maps.MapFragment"></fragment>
</LinearLayout>
問題是當我嘗試推出TJE 「ViatgeDetallActivity」,我得到這個在日誌中:

如果我理解正確的,你想我要更改的元素片段佈局的SupportMapFragment,但是Android工作室它不承認,作爲一個有效的類型! – Asdemuertes
