我尝试了在 android 中显示谷歌地图 v2 的演示。
java代码是,
package com.example.gpslocator;
import android.os.Bundle;
import android.app.Activity;
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;
}
}
Xml 代码是,
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_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>
我在 manifest.xml 中添加了 API 密钥,
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.gpslocator"
android:versionCode="1"
android:versionName="1.0" >

android:targetSdkVersion="17" />

<!--

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="MY_API_KEY" />
</application>
</manifest>
当我尝试运行我的应用程序时突然关闭。当我调试时,它向我显示了错误“java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable”。我将 google-play-services.jar 文件添加到我的应用程序中。
