在我的应用程序中显示的空地图

标签： android eclipse google-maps android-fragments google-play-services


我正在做一个使用谷歌地图的应用程序，但地图没有显示，我看到的唯一的是空白方块。

这是我的清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="fossa.damiano.mapsexample"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="17" />
    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <uses-library android:name="com.google.android.maps" />
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application> 
</manifest>

我的活动：

import android.os.Bundle;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView.LayoutParams;
import com.google.android.maps.MapView;
import android.view.View;
import android.widget.LinearLayout;

public class MainActivity extends MapActivity {
    MapView mapView;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mapView = (MapView) findViewById(R.id.mapView);
        LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);  
        View zoomView = mapView.getZoomControls(); 

        zoomLayout.addView(zoomView, 
            new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, 
                LayoutParams.WRAP_CONTENT)); 
        mapView.displayZoomControls(true);
    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }



}

和main.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
    tools:context=".MainActivity" >

     <com.google.android.maps.MapView
         android:id="@+id/mapview1"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:apiKey="My Key" //I've already generated my Key
         android:clickable="true" />

</RelativeLayout>

当我尝试将我的应用程序执行到智能手机时，logcat会显示这些错误。

我已启用互联网连接，因此无法找出问题所在。

更新
我已将Google地图的版本从1更新为2 以下是更改：

活动：

public class MonumentMapActivity extends Activity{

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

}

和xml：

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

          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

</RelativeLayout>

当我尝试执行代码时，它会给我这些错误：

更新2

我做了另一个只显示地图的应用程序，它可以工作!!
但是当我尝试将该代码添加到我的应用程序时，它会显示上面显示的相同错误！

那么，为什么地图不能同时适用于两个应用程序？

答案 0 :(得分：1)

从弃用的API v1迁移到API v2的最简单方法是

  1. 删除与地图相关的所有代码
  2. 点击此链接：https://developers.google.com/maps/documentation/android/start

答案 1 :(得分：1)

文档声明：

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

关于使用MapFragment类：

  

仅在您定位API 12及更高版本时才使用此课程。否则，请使用SupportMapFragment。

你最近SDK是11因此你应该使用SupportMapFragment或更改你的最低SDK级别。
