Java 我得不到地图视图和确切位置有人帮我吗？

这是我的密码。我尝试了这段代码，但在MapActivity、MapView和其他位置出现错误。当我写这段代码时，当我把光标放在那里，它不会显示导入选项。。。我不知道为什么。任何人都可以尝试使用此代码，但这些方法不在此处导入..请查看plz

package com.bened;

import android.os.Bundle;

public class mapExactDemoActivity extends MapActivity {
    /** Called when the activity is first created. */
    MapView mv;
    double lat=17.441966,lon=78.445127;
    GeoPoint gp;
    MapController mc;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mv=(MapView)findViewById(R.id.map);
        gp=new GeoPoint((int)(lat*1000000),(int)(lon*1000000));
        mc=mv.getController();
        mc.setCenter(gp);
        mc.setZoom(20);
        mv.setBuiltInZoomControls(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:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <com.google.android.maps.MapView
    android:id="@+id/map"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:apiKey="00S4pru3FgTKZjOlX2agvv2TBWx5p3sVbOvgiAw" 
    android:clickable="true"
    />

它不会购买导入选项

如果这是一种奇怪的说法，说明无法修复您的导入

只需执行以下操作即可组织导入：Ctrl+Shift+O

如果这不起作用，

请检查您是否使用了Google Apigool Inc.Sdk 2.2版或任何升级版本。

请编辑您的问题并插入错误例外？你正变得越来越聪明。这将帮助其他用户理解您的问题。我试图通过更正语法来解决您的问题，但我无法理解您的意思，如果我将光标放在那里，它不会显示导入选项。你能换个说法吗？确保你的钥匙有效。你可以通过这种方式得到钥匙：：耶…….我改变了我的工作地点，张贴了我的日志详细信息..在这里
