将Google地图渲染为片段时的黑色视图

本文介绍了将Google地图渲染为片段时的黑色视图的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

当我在渲染地图上滑动时,我在Android中使用的滑动菜单是

这是我的地图片段代码。

  public class BasicMapActivity extends SherlockFragment {
private MapView mMapView;
私有GoogleMap mMap;

@Override
public查看onCreateView(LayoutInflater inflater,
ViewGroup容器,
Bundled savedInstanceState){
查看视图= inflater.inflate(R.layout .basic_demo,null);
// view.setBackgroundColor(0x00000000);
mMapView =(MapView)view.findViewById(R.id.map);
container.requestTransparentRegion(mMapView);
mMapView.onCreate(savedInstanceState);
返回视图;


$ / code $ / pre

这里是我在家里的活动,

  @Override 
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);

setContentView(R.layout.activity_home_frame);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.home_screen,new BasicMapActivity())
.commit();


getSlidingMenu()。setSecondaryMenu(
getLayoutInflater()。inflate(R.layout.resq_events_frame,null));
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.resq_events_screen,new EventsFragment())
.commit();

//设置背后视图
setBehindContentView(R.layout.activity_settings_frame);

getSupportFragmentManager()
.beginTransaction()
.replace(R.id.settings_screen,new SettingsFragment())
.commit();

//自定义SlidingMenu
getSlidingMenu()。setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
}

我的XML文件看起来像这样

 <?xml version =1.0encoding =utf-8?> 
< FrameLayout xmlns:android =http://schemas.android.com/apk/res/android
android:id =@ + id / home_screen
android:layout_width =match_parent
android:layout_height =match_parent>
< / FrameLayout>

如何克服这个问题?

在这里如何看图像。



解决方案

问题归因于GoogleMap,您必须添加 map:zOrderOnTop =true添加到您的XML地图布局中,例如



 < LinearLayout xmlns:android = http://schemas.android.com/apk/res/android
android:layout_width =fill_parent
android:layout_height =fill_parent>

<片段
android:name =com.google.android.gms.maps.SupportMapFragment
xmlns:map =http://schemas.android.com / apk / res-auto
android:id =@ + id / map
android:layout_width =match_parent
android:layout_height =match_parent
map: zOrderOnTop =true/>

< / LinearLayout>


I'm using sliding menu for Android here is the link, when I slide on rendered map fragment, the sliding menu goes blank.

Here is my map fragment code.

public class BasicMapActivity extends SherlockFragment {
    private MapView mMapView;
    private GoogleMap mMap;

    @Override
    public View onCreateView(LayoutInflater inflater,
                             ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.basic_demo, null);
        // view.setBackgroundColor(0x00000000);
        mMapView = (MapView) view.findViewById(R.id.map);
        container.requestTransparentRegion(mMapView);
        mMapView.onCreate(savedInstanceState);
        return view;
    }
}

Here is my home activity where in i render map.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_home_frame);
    getSupportFragmentManager()
            .beginTransaction()
            .replace(R.id.home_screen, new BasicMapActivity())
            .commit();


    getSlidingMenu().setSecondaryMenu(
            getLayoutInflater().inflate(R.layout.resq_events_frame, null));
    getSupportFragmentManager()
            .beginTransaction()
            .replace(R.id.resq_events_screen, new EventsFragment())
            .commit();

    // set the Behind View
    setBehindContentView(R.layout.activity_settings_frame);

    getSupportFragmentManager()
            .beginTransaction()
            .replace(R.id.settings_screen, new SettingsFragment())
            .commit();

    // customize the SlidingMenu
    getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
}

My XML file looks like this

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/home_screen"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</FrameLayout>

How to overcome by this issue?

Here how the image looks.

解决方案

The issue is due to GoogleMap, you have to add this map:zOrderOnTop="true" to your XML map layout, like

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <fragment
        android:name="com.google.android.gms.maps.SupportMapFragment"
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        map:zOrderOnTop="true" />

</LinearLayout>
