Unity接入百度地图

我用的是Eclipse
1.首先去百度地图官网注册一个密钥

包名不一致的话会导致地图显示不出来，只显示网格

2.利用eclipse接入百度地图SDK
在项目中新建libs文件夹然后把以下文件放进去

（这些文件是从百度地图官网上下载的SDK中的）
下面是各个文件中的代码
主入口文件MainActivity.java

import android.os.Bundle;
import android.content.Intent;
import com.unity3d.player.UnityPlayerActivity;

public class MainActivity extends UnityPlayerActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
    
    public String getStringInJava() {
        return "i am a string from java";
    }
    
    public void OpenNewScene() {
        Intent intent = new Intent(MainActivity.this, EmptyScene.class);
        this.startActivity(intent);
    }
    
    public void OpenBaiduMap() {
        Intent intent = new Intent(MainActivity.this, MyBaiduMapActivity.class);
        this.startActivity(intent);
    }
}

EmptyScene.java

import android.app.Activity;
import android.os.Bundle;

public class EmptyScene extends Activity{

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

MyBaiduMapActivity.java

import com.baidu.mapapi.CoordType;
import com.baidu.mapapi.SDKInitializer;
import com.baidu.mapapi.map.MapView;
 
import android.app.Activity;
import android.os.Bundle;

public class MyBaiduMapActivity extends Activity {

    MapView mMapView = null;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {                
        super.onCreate(savedInstanceState);             
        SDKInitializer.initialize(getApplicationContext());     
        SDKInitializer.setCoordType(CoordType.BD09LL);
        setContentView(R.layout.activity_main);                
        mMapView = (MapView) findViewById(R.id.bmapView);   
    } 
    
    @Override
    protected void onDestroy() {        
        super.onDestroy();          
        //在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理          
        mMapView.onDestroy();    
    }

    @Override    
    protected void onResume() {        
        super.onResume();        
        //在activity执行onResume时执行mMapView. onResume ()，实现地图生命周期管理         
        mMapView.onResume();    
    }    
    @Override      
    protected void onPause() {          
        super.onPause();        
        //在activity执行onPause时执行mMapView. onPause ()，实现地图生命周期管理         
        mMapView.onPause();     
    }

}

布局文件Activity_main.xml 添加以下代码

<com.baidu.mapapi.map.MapView  
    android:id="@+id/bmapView"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent"  
    android:clickable="true" />

    </application>

</manifest>

3.导出文件给Unity

image.png

记得把libs里面的classes删除

image.png

assets文件夹在百度地图的demo找，据说不加这个程序会崩溃
Demo\BaiduMap_AndroidSDK_v5.2.0_Sample\BaiduMapsApiDemo

4.编写C#脚本，实现交互

void OnGUI() {
        if (GUILayout.Button("Open Map", GUILayout.Height(100))) {
            AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
            jo.Call("OpenBaiduMap");
        }

        if (GUILayout.Button("Open New Scene", GUILayout.Height(100))) {
            AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
            jo.Call("OpenNewScene");
        }

        if (GUILayout.Button("改变Label___New", GUILayout.Height(100))) {
            AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
            text.text = jo.Call<string>("getStringInJava");
        }
    }
