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
image.png
（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" />
主配置文件AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>

</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");
}
}
