我做了所有的配置。
I had done all configuration.
下面是我的清单文件：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-sdk android:minSdkVersion="3" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<application android:icon="@drawable/icon" android:label="@string/app_name">
<uses-library android:name="com.google.android.maps" />
<activity android:name="com.example.HelloMap"
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>
and my layout file main.xml is
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<com.google.android.maps.MapView
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="*************"
/>
</RelativeLayout>
和我Hellomap.java
And my Hellomap.java
public class HelloMap extends Activity {
LinearLayout linearLayout;
MapView mapView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mapview);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
}
protected boolean isRouteDisplayed() {
return false;
}
}
我丢失的东西我想，也许这个问题是2.1谷歌的API？
Something I am missing I guess, or maybe the issue is with 2.1 Google API?
推荐答案
我得到了我的answere自己
i got my answere myself
刚刚看到异常日志
最后几行
MapViews can only be created inside instances of MapActivity. 06-14 22:13:34.031: ERROR/AndroidRuntime(331): at com.google.android.maps.MapView.(MapView.java:281) 06-14 22:13:34.031:
这意味着你需要扩展与MapActivity不活动的活动我猜你们大多数人都知道，但我得到了现在知道 ：）
that means you need to extend your activity with MapActivity not Activity i guess most of you know but i got to know now :)
