【问题描述】：

这是我的代码。我尝试了这段代码，但在 MapActivity、MapView 和其他位置出现错误。当我将光标放在那里时编写此代码时，它没有显示导入选项...我不知道为什么。任何人都可以尝试使用此代码，这些方法不会在此处导入。请检查一下

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"
    />
</LinearLayout>

【问题讨论】：

请编辑您的问题并插入您遇到的错误（异常？）。这将帮助其他用户了解您的问题。
我试图通过更正语法来解决您的问题，但我无法理解您所说的“如果我把光标放在那里它不会购买导入选项”是什么意思。你能改写一下吗？
确保您的密钥有效。你可以通过这种方式获取密钥::stackoverflow.com/questions/6925659/…

【解决方案1】：

它不购买导入选项

如果这是一种奇怪的说法“不修复你的导入”

只需这样做来组织你的导入： Ctrl + Shift + O

如果这不起作用，setup your project properly

【解决方案2】：

请检查您是否使用过 Google API(Google Inc.) Sdk 模拟器 2.2 或任何升级版本。
