android - Google Maps API v2 无法显示 map

标签 android google-maps

我是 Stackoverflow 的新手。我在新的 Google Maps API v2 上显示 map 时遇到问题。 我完成了此页面 https://developers.google.com/maps/documentation/android/start?hl=pl 中的所有步骤ans 一些教程，我无法显示 map 。当我运行我的应用程序时，在模拟器上仅显示放大控件，其余屏幕为白色，我无法在我的真实设备(HTC Wildfire S-android 2.3.5)上打开它。我也将 google_play_service_lib 添加到我的项目中。我在很多页面和很多教程中寻找我的问题的答案，但我没有找到它!请帮助我!

这是我的 list 文件:

有MainActivity的代码:

package com.adrianspora.googlemaptest;

import com.google.android.gms.maps.MapFragment;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

public class MainActivity extends Activity {

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

    }

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

}

这是主要布局的代码:

<LinearLayout 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" >


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

</LinearLayout>

LogCat 中显示了一个日志列表:

最佳答案

您应该使用 Support Fragment，因为您的 min sdk 是 8。

https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/SupportMapFragment 

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

您的 Activity 必须扩展 FragmentActivity 并使用下面的代码初始化 GoogleMap 对象。

SupportMapFragment fm = (SupportMapFragment)  getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap();

确保你已经添加了支持库

还要确保您导入了以下内容

import android.support.v4.app.FragmentActivity;  
import com.google.android.gms.maps.SupportMapFragment;

检查您是否在服务选项卡下的 google api 控制台中为 android 启用了 map 。

检查您是否遵循了文档中提到的所有步骤

https://developers.google.com/maps/documentation/android/start

你也可以查看我回答过的类似问题。

App shows grid screen instead of google map

When i run my application, on emulator displays only magnification controls and rest screen is white

您应该在真实设备上对其进行测试。
