我的模拟器中出现空白屏幕，并且地图没有显示。
这是假设在浏览器中显示的内容：[ http://code.google.com/apis/maps/documentation/javascript/examples/layer-georss.html]
这是清单文件的代码：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.apps.mylocations"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".MyLocations"
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>
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
</manifest>
这是我的布局 XML 文件，它有一个webview：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView android:id="@+id/web_engine"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
这是Java代码：
package com.apps.mylocations;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class MyLocations extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView engine = (WebView) findViewById(R.id.web_engine);
engine.getSettings().setJavaScriptEnabled(true);
