Android Fragment展示Unity场景
unity导入Android说明
新建项目
首先新建一个unity项目和一个Android项目，对应本demo的UnityScene和AndroidProject
Unity Scene
将unity配置为Android
file --> buildingSettings
选择Android，点击switch platform。
构建项目
勾选export project，building，新建UnityScene文件夹保存，导出后文件结构大致如下
引入到Android项目中
以下文件放到Android 项目中对应位置（我仅导出arm-v7）
unity-classes.jar, armeabi-v7a放到Android project的app/libs目录下；assets文件夹放到app/src/main文件夹下，与java同级。Android Studio文件结构如下
gradle中添加（与buildTypes同级）
sourceSets {
main {
//unity3D
jniLibs.srcDirs = ['libs', 'libs-sdk']
}
}
defaultConfig中添加
ndk {
abiFilters "armeabi-v7a"
}
在local.properties中配置ndk（替换你自己的ndk）
ndk.dir=.../Android/sdk/ndk/xxxx
Android架构中应当看到
Android Project
创建Fragment
创建UnityScene.java
package com.example.androidproject.unity;
import com.unity3d.player.UnityPlayer;
public class UnityScene {
public static UnityPlayer mUnityPlayer;
public UnityScene(){
}
}
创建一个空的Fragment，添加如下代码
private View playerView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
playerView = UnityScene.mUnityPlayer.getView();
//具体参数 跟自己公司Unity开发人员协商
//第一个参数是unity那边的挂载脚本名字
//第二个参数是 unity提供的方法名
//第三个参数是 自己要给unity传的值
// UnityScene.mUnityPlayer.UnitySendMessage("Main Camera","Id","1");
return playerView;
}
改写MainActivity
在MainAcivity的onCreate中添加
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重写其他方法
@Override
protected void onDestroy() {
UnityScene.mUnityPlayer.quit();
super.onDestroy();
}
@Override
protected void onPause() {
super.onPause();
UnityScene.mUnityPlayer.pause();
}
@Override
protected void onResume() {
super.onResume();
UnityScene.mUnityPlayer.resume();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
UnityScene.mUnityPlayer.configurationChanged(newConfig);
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
UnityScene.mUnityPlayer.windowFocusChanged(hasFocus);
}
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
return UnityScene.mUnityPlayer.injectEvent(event);
return super.dispatchKeyEvent(event);
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
return UnityScene.mUnityPlayer.injectEvent(event);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
return UnityScene.mUnityPlayer.injectEvent(event);
}
@Override
public 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中添加
Game View
完成
运行项目即可看到unity场景嵌套在fragment中
