我有地图视图的问题。这是代码：

安卓清单： 

<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.INTERNET"/>
<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=".TestjmkapActivity" >
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />

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

活动：

package test.pl.pl;

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

public class TestjmkapActivity extends MapActivity {

    MapView mapView;
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mapView = (MapView)findViewById(R.id.map);

        mapView.setBuiltInZoomControls(true);
        mapView.setTraffic(false);
        mapView.setSatellite(true);
        mapView.setStreetView(true);
    }

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

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

<com.google.maps.MapView
    android:id="@+id/map"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="100dp"
    android:layout_width="100dp"
        android:enabled="true"
    android:clickable="true"
    android:apiKey="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
    />

</LinearLayout>

这是我尝试启动它时在 logcat 中得到的：

也许 xml mapview 中的这一行使其失败：

xmlns:android="http://schemas.android.com/apk/res/android"
