Android中启用unity

首先在Unity下创建一个新的工程，然后建立场景，导出成安卓项目。（我用的是一个AR项目）

当导出的android项目导入Eclipse，

新建一个Activity，并在AndroidManifest中设置这个Activity为MainActivity

<activity

android:name="com.xxx.xxx.NewActivity"

android:label="@string/app_name">

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

</activity>

把原有的

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

删掉。

程序启动时显示的Activity代码:

package com.studio.androidpart.activity;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import com.studio.unitypart.R;

import com.studio.unitypart.UnityPlayerActivity;

public class HomePageActivity extends Activity {

Button b;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.homepage);

b = (Button) findViewById(R.id.enterButton);

//点击按钮切换场景

b.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

Intent i=new Intent(HomePageActivity.this,UnityActivity.class);

startActivity(i);

}

});

}

}

xml文件:

<?xml version="1.0" encoding="UTF-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:background="#ffffff"

>

<Button

android:id="@+id/enterButton"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerHorizontal="true"

android:layout_centerVertical="true"

android:text="Button" />

</RelativeLayout>

再新建一个Activity，这个Activity需要继承自UnityPlayerActivity，并且需要为这个Activity建立一个布局(可能用来承载Unity的场景呈现)

布局文件

<?xml version="1.0" encoding="UTF-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/unity_scene"

android:layout_width="match_parent"

android:layout_height="match_parent">

</RelativeLayout>

Activity文件:

package com.studio.androidpart.activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.KeyEvent;

import android.widget.RelativeLayout;

import com.studio.unitypart.R;

import com.unity3d.player.UnityPlayerActivity;

public class UnityActivity extends UnityPlayerActivity{

private RelativeLayout u3dLayout;

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.arscene);

u3dLayout = (RelativeLayout) findViewById(R.id.unity_scene);

u3dLayout.addView(mUnityPlayer);

mUnityPlayer.requestFocus();

}

@Override

/**

* 响应手机物理返回键

*/

public boolean onKeyDown(int keyCode, KeyEvent event) {

if (keyCode == KeyEvent.KEYCODE_BACK&& event.getRepeatCount() == 0) {

Intent i=new Intent(UnityActivity.this,HomePageActivity.class);

startActivity(i);

return true;

}

return super.onKeyDown(keyCode, event);

}

}

新的Activity也要在AndroidManifest中配置下

然后run就可以了
