Question

出于某种原因，我无法使MapView正常工作。我花了几天时间对它进行研究，我的代码看起来很好（这意味着它看起来与不同的教程完全一样），但每次我启动它时，它都会崩溃。 Eclipse和控制台信息不会显示错误。

有没有人有解决方案？

HelloMapActivity.java文件：

package com.com.google.maps;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import android.os.Bundle;

public class HelloMapActivity extends MapActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}

main.xml文件：

<?xml version="1.0" encoding="utf-8"?>

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

 <com.google.android.maps.MapView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/mapview"
  android:clickable="true" 
  android:enabled="true" 
  android:apiKey="<Api-key>" />

</RelativeLayout>

最后，Manifest：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.com.google.maps"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="7" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <uses-library android:name="com.google.android.maps" />
        <activity
            android:label="@string/app_name"
            android:name=".HelloMapActivity"   android:theme="@android:style/Theme.NoTitleBar">
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>

这就是说LogCat：

Answer 1

我遇到了同样的问题并且发现它来自互联网连接（也无法通过浏览器访问互联网）。我尝试从“Android SDK和AVD Manager”启动AVD，它正在运行。希望能帮助一些人。

Answer 2

你可以为崩溃添加一些日志，也可以尝试将以下权限添加到清单

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"> </uses-permission>

Answer 3

我认为你需要尝试添加

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

到您的清单。

Answer 4

您需要<uses-library android:name="com.google.android.maps" />

作为清单中标记的子项。 ala

<?xml version="1.0" encoding="utf-8"?>

<uses-sdk android:minSdkVersion="7" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <uses-library android:name="com.google.android.maps" />
    <activity
        android:label="@string/app_name"
        android:name=".HelloMapActivity"   android:theme="@android:style/Theme.NoTitleBar">
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
<uses-library android:name="com.google.android.maps" />
</application>

Answer 5

11-01 22：22：56.826：W / dalvikvm（193）:( Lcom / com / google / maps / HelloMapActivity;曾使用过不同的Lcom / google / android / maps / MapActivity;验证）

我想知道您的安装和设置是否正确。可能你有两个版本的Google Maps API。

我建议删除并重新安装Google Maps API并重新制作Android项目。
