添加自定义视图（线性布局），以支援地图片段的顶部失败

Question

我工作的一个项目，并按照下列指示

（How to add buttons at top of map fragment API v2 layout）

我上的添加成分成功地图片段的顶部（不是支持地图片段）。在那之后，我做了一个改变我的代码，并按照以下步骤

（SupportMapFragment Instead of MapFragment）

我改变了我的地图片段支持地图片段。我没有任何东西从我的地图XML改变，除了

class="com.google.android.gms.maps.MapFragment" 

到

class="com.google.android.gms.maps.SupportMapFragment" 

，但是当我跑我的应用我的线性布局不会在地图上显示了。 我试图从FrameLayout改为RelativeLayout并添加一些属性，但它似乎仍然与我的LinearLayout重叠。

是否有遗漏或错误的地方？

PS。在XML图形布局视图中，我可以看到线性布局在地图上正确定位。

从MainActivity.java，onNavigationDrawerItemSelected方法，其中创建MapFragment

@Override 
    public void onNavigationDrawerItemSelected(int position) { 
     // update the main content by replacing fragments 
     Fragment fragment; 
     FragmentManager fragmentManager; 
     switch (position) { 
     default: 
     case 0: 
      fragment = MapFragment.newInstance(position + 1); 
      onSectionAttached(position + 1); 
      break; 
     } 
     fragmentManager = getSupportFragmentManager(); 
     fragmentManager.beginTransaction().replace(R.id.container, fragment) 
       .commit(); 

    } 

MapFragment.java

import android.app.Activity; 
    import android.content.Context; 
    import android.location.LocationManager; 
    import android.os.Build; 
    import android.os.Bundle;

    /**

      } else { 
       // Log.d(TAG, "using getChildFragmentManager");

      } 

      return (SupportMapFragment) fm.findFragmentById(R.id.map); 
     }

Answer 1

进入XML文件

<fragment 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     class="com.google.android.gms.maps.SupportMapFragment" /> 

应该

<FrameLayout 
     android:id="@+id/container" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

，因为你开始进入导航抽屉：

fragmentManager.beginTransaction().replace(R.id.container, fragment) 
       .commit(); 

但没有ID =集装箱。

Answer 2

在您的活动，保持对它的引用您的线性布局

LinearLayout root = (LinearLayout) findViewById(R.id.root); 

然后将片段添加到与片段交易的布局后，通过做

root.bringToFront();
