SupportMapfragment does not fill parent

Question

當我在運行時用SupportMapFragment替換容器時，它不會填充Parent。它僅部分佔據屏幕。

HomeActivity2.java

package com.example.mapdemo; 

import com.meteraid.android.services.LocationService; 

import android.location.Location; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.ViewGroup.LayoutParams; 


public class HomeActivity2 extends BaseActivity2 { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_home_activity2); 

     LocationService locationService=LocationService.getInstance(this); 
     Location location=locationService.getCurrentLocation(); 

     GoogleMapFragment mapFragment=new GoogleMapFragment(); 


     mapFragment.setCurrentLocation(location); 



     android.support.v4.app.FragmentTransaction fragmentTransaction=getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.replace(R.id.fragment_container,mapFragment);  
     fragmentTransaction.commit();  


    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.home_activity2, menu); 
     return true; 
    } 

} 

GoogleMapFragment

package com.example.mapdemo; 

import android.os.Bundle; 
import android.support.v4.widget.DrawerLayout; 
import android.util.Log; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.view.ViewGroup.LayoutParams; 
import android.widget.Toast; 

import com.google.android.gms.maps.CameraUpdateFactory; 
import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.SupportMapFragment; 
import com.google.android.gms.maps.UiSettings; 
import com.google.android.gms.maps.model.CameraPosition; 
import com.google.android.gms.maps.model.LatLng; 

import android.location.Location; 

public class GoogleMapFragment extends SupportMapFragment { 

    private static View view; 
    private Location location; 

    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     view = super.onCreateView(inflater, container, savedInstanceState); 


     Toast.makeText(getActivity(), "kkd",Toast.LENGTH_LONG).show(); 
     initMap(location); 
     return view; 

    } 

    public void setCurrentLocation(Location location) { 
     this.location = location; 
    } 

    public void initMap(Location location) { 

     GoogleMap map = getMap(); 

     Log.e("Locationnnnnnnnnn", location+""); 
     CameraPosition currentLocation = new CameraPosition.Builder() 
       .target(new LatLng(location.getLatitude(), location 
         .getLongitude())).zoom(4f).bearing(0).tilt(0).build(); 

     map.moveCamera(CameraUpdateFactory.newCameraPosition(currentLocation)); 

     //map.setMyLocationEnabled(true); 
     map.setMapType(GoogleMap.MAP_TYPE_NORMAL); 

    } 

} 

activity_home_activity2.xml

<FrameLayout 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:paddingBottom="@dimen/activity_vertical_margin" 
      android:paddingLeft="@dimen/activity_horizontal_margin" 
      android:paddingRight="@dimen/activity_horizontal_margin" 
      android:paddingTop="@dimen/activity_vertical_margin" 
      android:id="@+id/fragment_container" 
      android:background="#cccccc"  
      tools:context=".HomeActivity2">   
</FrameLayout>

看起來你已經設置了填充。刪除你的填充，再次建立你的應用程序，並檢查是否有效。
