3/30每日总结：地图下钻功能的实现

所花时间：3小时

代码量：如下：

博客量：本学期截至目前31篇

了解到的知识点：地图下钻

在main中新建

 

然后导入html文件

其中代码如下：

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <!--重要meta, 必须!-->
    <meta name="viewport" content="width=320, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0,shrink-to-fit=no" />
    <title>SUBWAY</title>
</head>
<body>
<div id="mybox"></div>
<script src="https://webapi.amap.com/subway?v=1.0&key=b09132fa0d59581435755699c411c397&callback=cbk"></script>
<script type="text/javascript">
    window.cbk = function() {
        var mySubway = subway("mybox", {
            adcode: 1100,
            theme: "colorful",
            client: 0,
            doubleclick: {
                switch: true
            }
        });
        //地铁加载完成，执行complete事件
        mySubway.event.on("subway.complete", function(ev, info) {
            var id = info.id;
        });

        //点击站点，显示此站点的信息窗体
        mySubway.event.on("station.touch", function(ev, info) {
            var id = info.id;
            mySubway.stopAnimation();
            mySubway.addInfoWindow(id, {});
            var center = mySubway.getStCenter(id);
            mySubway.setCenter(center);
        });

        //点击线路名，高亮此线路
        mySubway.event.on("lineName.touch", function(ev, info) {
            mySubway.showLine(info.id);
            var select_obj = qs('#g-select');
            mySubway.setFitView(select_obj);
            var center = mySubway.getSelectedLineCenter();
            mySubway.setCenter(center);
        });

        //点击空白, 关闭infowindow
        mySubway.event.on("subway.touch", function() {
            mySubway.clearInfoWindow();
        });

        //设置起点
        mySubway.event.on("startStation.touch", function(ev, info) {
            mySubway.stopAnimation();
            mySubway.clearInfoWindow();
            mySubway.setSt
            art(info.id, {});
            startInfo = info;
            route();
        });

        //设置终点
        mySubway.event.on("endStation.touch", function(ev, info) {
            mySubway.stopAnimation();
            mySubway.clearInfoWindow();
            mySubway.setEnd(info.id, {});
            endInfo = info;
            route();
        });

        //路线规划
        var startInfo = {},
            endInfo = {};
        function route() {
            if (startInfo.id && endInfo.id) {
                mySubway.route(startInfo.id, endInfo.id, {});
                startInfo = {};
                endInfo = {};
            }
        }
    };
</script>
</body>

　　这个key的值可能不一样可能需要改。

MainActivity代码：

package com.example.chaxun;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import com.example.chaxun.Dao.Dao;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    Dao Dao = new Dao();
    private Intent intent;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findViewById(R.id.btn_selectbyline).setOnClickListener(this);
        findViewById(R.id.btn_selectbystation).setOnClickListener(this);
        findViewById(R.id.btn_selectbetween).setOnClickListener(this);
        findViewById(R.id.btn_ditu).setOnClickListener(this);
    }
    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btn_selectbyline:
                intent = new Intent(MainActivity.this, SearchLineActivity.class);
                startActivity(intent);
                break;
            case R.id.btn_selectbystation:
                intent = new Intent(MainActivity.this, SearchStationActivity.class);
                startActivity(intent);
                break;
            case R.id.btn_selectbetween:
                intent = new Intent(MainActivity.this, ChangeStationActivity.class);
                startActivity(intent);
                break;
                case R.id.btn_ditu:
                intent = new Intent(MainActivity.this, MapActivity.class);
                startActivity(intent);
                break;
        }
    }

}

　　xml中的代码：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MapActivity">

    <!--    <TextView-->
    <!--        android:layout_width="wrap_content"-->
    <!--        android:layout_height="wrap_content"-->
    <!--        android:text="Hello World!"-->
    <!--        app:layout_constraintBottom_toBottomOf="parent"-->
    <!--        app:layout_constraintLeft_toLeftOf="parent"-->
    <!--        app:layout_constraintRight_toRightOf="parent"-->
    <!--        app:layout_constraintTop_toTopOf="parent" />-->


    <WebView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/mWebView">
    </WebView>

</androidx.constraintlayout.widget.ConstraintLayout>

　　这样就能实现地图下钻的功能了
