unity匯入Android說明新建專案

首先新建一個unity專案和一個Android專案，對應本demo的UnityScene和AndroidProject

Unity Scene將unity配置為Android

file --> buildingSettings

構建專案

勾選export project，building，新建UnityScene資料夾儲存，匯出後文件結構大致如下

引入到Android專案中

以下檔案放到Android 專案中對應位置（我僅匯出arm-v7）

unity-classes.jar, armeabi-v7a放到Android project的app/libs目錄下；assets資料夾放到app/src/main資料夾下，與java同級。Android Studio檔案結構如下

gradle中新增（與buildTypes同級）

sourceSets {    main {        //unity3D        jniLibs.srcDirs = ['libs', 'libs-sdk']    }}

defaultConfig中新增

        ndk {            abiFilters "armeabi-v7a"        }

在local.properties中配置ndk（替換你自己的ndk）

ndk.dir=.../Android/sdk/ndk/xxxx

Android架構中應當看到

Android Project建立Fragment

建立UnityScene.java

package com.example.androidproject.unity;import com.unity3d.player.UnityPlayer;public class UnityScene {    public static UnityPlayer mUnityPlayer;    public UnityScene(){    }}

建立一個空的Fragment，新增如下程式碼

 private View playerView;    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container,                             Bundle savedInstanceState) {        // Inflate the layout for this fragment        playerView = UnityScene.mUnityPlayer.getView();        //具體引數 跟自己公司Unity開發人員協商        //第一個引數是unity那邊的掛載指令碼名字        //第二個引數是 unity提供的方法名        //第三個引數是 自己要給unity傳的值//        UnityScene.mUnityPlayer.UnitySendMessage("Main Camera","Id","1");        return playerView;    }

改寫MainActivity

在MainAcivity的onCreate中新增

UnityScene.mUnityPlayer = new UnityPlayer(getApplicationContext());getWindow().setFormat(PixelFormat.RGBX_8888);if (savedInstanceState == null) {    getSupportFragmentManager().beginTransaction()            .setReorderingAllowed(true)            .add(R.id.fragment_container_view, UnityFragment.class, null)            .commit();}

MainAcivity重寫其他方法

@Overrideprotected void onDestroy() {    UnityScene.mUnityPlayer.quit();    super.onDestroy();}@Overrideprotected void onPause() {    super.onPause();    UnityScene.mUnityPlayer.pause();}@Overrideprotected void onResume() {    super.onResume();    UnityScene.mUnityPlayer.resume();}@Overridepublic void onConfigurationChanged(Configuration newConfig) {    super.onConfigurationChanged(newConfig);    UnityScene.mUnityPlayer.configurationChanged(newConfig);}@Overridepublic void onWindowFocusChanged(boolean hasFocus) {    super.onWindowFocusChanged(hasFocus);    UnityScene.mUnityPlayer.windowFocusChanged(hasFocus);}@Overridepublic boolean dispatchKeyEvent(KeyEvent event) {    if (event.getAction() == KeyEvent.ACTION_MULTIPLE)        return UnityScene.mUnityPlayer.injectEvent(event);    return super.dispatchKeyEvent(event);}@Overridepublic boolean onKeyUp(int keyCode, KeyEvent event) {    return UnityScene.mUnityPlayer.injectEvent(event);}@Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) {    return UnityScene.mUnityPlayer.injectEvent(event);}@Overridepublic boolean onTouchEvent(MotionEvent event) {    return UnityScene.mUnityPlayer.injectEvent(event);}public boolean onGenericMotionEvent(MotionEvent event) {    return UnityScene.mUnityPlayer.injectEvent(event);}

gradle中增加

    implementation "androidx.fragment:fragment:1.2.1"

activity_main.xml如下

<?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context=".MainActivity">    <androidx.fragment.app.FragmentContainerView        xmlns:android="http://schemas.android.com/apk/res/android"        android:id="@+id/fragment_container_view"        android:layout_width="match_parent"        android:layout_height="500dp"        app:layout_constraintTop_toTopOf="parent" /></androidx.constraintlayout.widget.ConstraintLayout>

string.xml中新增

<string name="game_view_content_description">Game View</string>

完成

執行專案即可看到unity場景巢狀在fragment中
