我已经完成了这个

package androi.com.MapView;

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

import android.os.Bundle;

public class TestingMapViewActivity extends MapActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // setContentView(R.layout.main);
        // Intent i = new Intent(TestingMapViewActivity.this, tets.class);
        // startActivity(i);
        MapView mv = new MapView(this,
                "key");
        setContentView(mv);
    }

    @Override
    protected boolean isRouteDisplayed() {

        return false;
    }
![this is snap][1]
}

我也尝试使用XML文件

<?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" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
   <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="key" />

manifest资源配置文件

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

    <uses-sdk android:minSdkVersion="8" />

     <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />


    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".TestingMapViewActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="tets"></activity>
    </application>
<uses-library android:name="com.google.android.maps" />
</manifest>

Answer 1

你应该试试这个教程

http://developer.android.com/resources/tutorials/views/hello-mapview.html

Answer 2

你的Manifest文件中存在问题，

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

应该在下面的内容中

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

Answer 3

将清单更改为将库使用到应用程序标记中。

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

<uses-sdk android:minSdkVersion="8" />

 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />


<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".TestingMapViewActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="tets"></activity>
    <uses-library android:name="com.google.android.maps" />
</application>

Answer 4

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

的一侧添加<application>
