安卓原生百度地圖（4）路線規划

一、靜態規划路線

二、駕車、公交規划路線（輸入框版）

靜態規划路線：

1、配置路線規划的資源（提取碼：84la）

(1).復制assets里面的文件到項目中的assets中

 

(2).values中的styles.xml替換項目的styles.xml

(3).在下載的com文件中找到“baidu”文件夾，復制到項目中的java/com文件下

(4).在下載的layout中找到“text_bubble.xml”文件，復制放到項目中的layout下

2、在布局文件中加入新的路線規划按鈕

<Button
        android:id="@+id/btn_Plan"
        android:text="規划"
        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" />

 3、MainActivity代碼

                .to(enNode));
    }
}

 4、運行項目

5、附上項目（提取碼：52p3）（下載下來的項目點擊規划，會出現如下情況）

代碼段報：

6、原因是因為AndroidManifest.xml中沒有key，新建一個項目，拿到SHA1，到百度控制台新建一個應用，獲取key即可。

<---------以上代碼是靜態規划路線-----------以下代碼是動態規划路線-------------------->

駕車、公交規划路線（輸入框版）：

1.新增加了公交規划、輸入地址規划、靜態經緯度規划，在原來的基礎上加代碼（MainActivity代碼）：

2.跳轉到規划路線輸入框的代碼頁（RoutePlanActivity）：

package com.example.baidumap;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
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;
    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, "起點和終點不能為空" , 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();
        }
    }
}

3.RoutePlanActivity的布局頁面代碼（activity_route_plan）:

package com.example.baidumap;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
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;
    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, "起點和終點不能為空" , 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，如果整個代碼復制過去的話（自個創建可忽略），要在AndroidManifest.xml文件中加上如下代碼：

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

5.啟動項目（例圖）：

最后附上項目（點擊獲取，提取碼：8y7z），下載下來的項目直接運行可能會出現以上錯誤，需要開發者的KEY
