Hotel_Location.xml：如何訪問片段標籤到另一個活動的Android
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<fragment
android:id="@+id/googleMapLocation"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="fill_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
HotelLocation.java：
public class HotelLocation extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savaedInstanceState) {
return inflater.inflate(R.layout.activity_hotel_location,container,false);
}
}
HotelDetails.java
public class HotelDetails extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hotel_details);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Location"));
tabLayout.addTab(tabLayout.newTab().setText("Direction"));
tabLayout.setTabTextColors(getResources().getColorStateList(android.R.color.black));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final MapsPagerAdapter adapter = new MapsPagerAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener()
{
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
SupportMapFragment supportMapFragment =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.googleMapLocation);
googleMap = supportMapFragment.getMap();
googleMap.setMyLocationEnabled(true);
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String bestProvider = locationManager.getBestProvider(criteria, true);
location = locationManager.getLastKnownLocation(bestProvider);
if (location != null) {
onLocationChanged(location);
}
locationManager.requestLocationUpdates(bestProvider, 10000, 0,
this);
}
}
supportMapFragment在運行時返回null。
我做錯了什麼。誰能幫幫我嗎。 在此先感謝
