如何解决android中的谷歌地图视图？当我尝试这个程序时，我得到了以下错误

Manifost文件：

SampleApplication.java

package com.example;  
    import android.app.Activity;
    import android.os.Bundle;

    public class SampleMapApplication extends Activity {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);


        }
        protected boolean isRouteDisplayed() 
        {
            return false;
        }
    }

    Main.Xml:
        <?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="0U7-rnRk3Os0sPZnZF9iejONnHMsGRLxU0JbrBg"/>
    </LinearLayout>

错误： 输出如下所示

SampleApplication.java

package com.example;  
    import android.app.Activity;
    import android.os.Bundle;

    public class SampleMapApplication extends Activity {
        /** Called when the activity is first created. */

        }
        protected boolean isRouteDisplayed() 
        {

首先创建新的Android项目并选择目标设备是Android google api而不仅仅是Android api

SampleApplication.java

package com.example;  
    import android.app.Activity;
    import android.os.Bundle;

    public class SampleMapApplication extends Activity {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);


        }
        protected boolean isRouteDisplayed() 
        {
            return false;
        }
    }

    Main.Xml:
        <?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="0U7-rnRk3Os0sPZnZF9iejONnHMsGRLxU0JbrBg"/>
    </LinearLayout>

Main.xml：-

SampleApplication.java

package com.example;  
    import android.app.Activity;
    import android.os.Bundle;

    public class SampleMapApplication extends Activity {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);


        }
        protected boolean isRouteDisplayed() 
        {
            return false;
        }
    }

    Main.Xml:
        <?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="0U7-rnRk3Os0sPZnZF9iejONnHMsGRLxU0JbrBg"/>
    </LinearLayout>

试试看。

如果我添加此说明资源路径位置类型MapActivity无法解析为类型，因为您正在选择应用程序的目标设备没有Google API，请检查它。我如何检查它。我无法理解，请选择谷歌Api 2.2设备。尝试下载谷歌公司发布的谷歌Api，Android Api 8，第8版。

SampleApplication.java

package com.example;  
    import android.app.Activity;
    import android.os.Bundle;

    public class SampleMapApplication extends Activity {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);


        }
        protected boolean isRouteDisplayed() 
        {
            return false;
        }
    }

    Main.Xml:
        <?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="0U7-rnRk3Os0sPZnZF9iejONnHMsGRLxU0JbrBg"/>
    </LinearLayout>
