安卓原生百度地图（4）路线规划

一、静态规划路线

二、驾车、公交规划路线（输入框版）

静态规划路线：

1、配置路线规划的资源（提取码：84la）

(1).复制assets里面的文件到项目中的assets中

 

(2).values中的styles.xml替换项目的styles.xml

(3).在下载的com文件中找到“baidu”文件夹，复制到项目中的java/com文件下

(4).在下载的layout中找到“text_bubble.xml”文件，复制放到项目中的layout下

2、在布局文件中加入新的路线规划按钮

<Button
        android:id="@+id/btn_Plan"
        android:text="规划"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="60dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

 4、运行项目

5、附上项目（提取码：52p3）（下载下来的项目点击规划，会出现如下情况）

代码段报：

6、原因是因为AndroidManifest.xml中没有key，新建一个项目，拿到SHA1，到百度控制台新建一个应用，获取key即可。

<---------以上代码是静态规划路线-----------以下代码是动态规划路线-------------------->

驾车、公交规划路线（输入框版）：

1.新增加了公交规划、输入地址规划、静态经纬度规划，在原来的基础上加代码（MainActivity代码）：

2.跳转到规划路线输入框的代码页（RoutePlanActivity）：

package com.example.baidumap;

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import java.util.ArrayList;
import java.util.List;

public class RoutePlanActivity extends AppCompatActivity implements View.OnClickListener{
    private Button btnDrive,btnBus;

    @Override

        super.onCreate(savedInstanceState);

3.RoutePlanActivity的布局页面代码（activity_route_plan）:

import android.os.Bundle;
import android.util.Log;
import android.view.View;

import android.widget.Toast;

import java.util.ArrayList;
import java.util.List;

public class RoutePlanActivity extends AppCompatActivity implements View.OnClickListener{
    private Button btnDrive,btnBus;
    private EditText start_edt_city,start_edt_address,end_edt_city,end_edt_address;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_route_plan);
        initView();
    }

    private void initView(){
        btnDrive = (Button)findViewById(R.id.btn_drive);
        btnBus = (Button)findViewById(R.id.btn_bus);

        start_edt_city = (EditText)findViewById(R.id.Start_Edt_City);
        start_edt_address = (EditText)findViewById(R.id.Start_Edt_Address);
        end_edt_city = (EditText)findViewById(R.id.End_Edt_City);
        end_edt_address = (EditText)findViewById(R.id.End_Edt_Address);

        btnDrive.setOnClickListener(this);
        btnBus.setOnClickListener(this);
    };

    @Override
    public void onClick(View view) {
        String startCity = start_edt_city.getText().toString();
        String startAddress = start_edt_address.getText().toString();
        String endCity = end_edt_city.getText().toString();
        String endAddress = end_edt_address.getText().toString();

        ArrayList<String> addressList = new ArrayList<>();
        addressList.add(startCity);
        addressList.add(startAddress);
        addressList.add(endCity);
        addressList.add(endAddress);

        if(startCity.isEmpty() || startAddress.isEmpty() || endCity.isEmpty() || endAddress.isEmpty()){
            Toast.makeText(this, "起点和终点不能为空" , Toast.LENGTH_SHORT).show();
        }else {
            Intent intent = new Intent();
            intent.putStringArrayListExtra("address",addressList);

            switch (view.getId()) {
                case R.id.btn_drive:
                    setResult(1,intent);
                    break;
                case R.id.btn_bus:
                    setResult(2,intent);
                    break;
            }
            finish();
        }
    }
}

 4.最后一步，如果整个代码复制过去的话（自个创建可忽略），要在AndroidManifest.xml文件中加上如下代码：

<activity android:name=".RoutePlanActivity"></activity>

5.启动项目（例图）：

最后附上项目（点击获取，提取码：8y7z），下载下来的项目直接运行可能会出现以上错误，需要开发者的KEY
