Unity安卓开屏动画

在Unity应用启动时，加自定义的开屏动画意义
1、可以遮住Unity个人版的启动log
2、防止unity黑屏太久时间导致玩家不愿意等待

#步骤

一、创建动画的布局界面

activity_main.xml的布局设置

<RelativeLayout 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"
    android:layout_centerInParent="false">

    <ImageView
        android:id="@+id/splash_frame"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:adjustViewBounds="false"
        android:scaleType="fitCenter"
        android:src="@drawable/sequence"
        tools:src="@drawable/sequence" />

RelativeLayout>

动画布局
sequence.xml
drawable/splash_ani_0表示drawable文件夹中的图片名字

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="true"
    >
    <item android:duration="40" android:drawable="@drawable/splash_ani_0"/>
    <item android:duration="40" android:drawable="@drawable/splash_ani_1"/>
animation-list>

二、在代码中调用

在主Activity代码中调用

// 启动图组件
private ImageView bgView = null;
private View view = null;
AnimationDrawable animationDrawable = null;
//mUnityPlayer是UnityPlayerActivity中的变量，可以直接使用

@Override // com.unity3d.player.UnityPlayerActivity
public void onCreate(Bundle savedInstanceState) {
    //在onCreate方法中通过UI线程的方式调用
    activity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            showSplash();
        }
    });
}

public void showSplash(){
    Log.i(Tag, "showSplash");

    if (bgView != null || mUnityPlayer == null)
        return;

    //先为画布添加一层背景
    bgView = new ImageView(this);
    int color_splash_bg = R.color.color_splash_bg;
    bgView.setBackgroundColor(getResources().getColor(color_splash_bg));
    mUnityPlayer.addView(bgView);

    //将我们创建的活动页添加到应用画布上
    LayoutInflater flater = LayoutInflater.from(this);
    int layoutID = getResources().getIdentifier("activity_main", "layout", getPackageName());
    view = flater.inflate(layoutID, null);

    int frame_id = view.getResources().getIdentifier("splash_frame", "id", getPackageName());
    ImageView frameView = (ImageView)view.findViewById(frame_id);
    mUnityPlayer.addView(view);

    //启用动画，此处利用程序动态控制方便后面关闭
    animationDrawable = (AnimationDrawable) frameView.getDrawable();
    animationDrawable.start();
}

这样子就能在启动UnityActivity时展示一个开屏动画了
既然有显示，那当然需要隐藏了,在UI线程中调用就行，可以在进入到下载或者登录界面时关闭这个动画

private void hideSplash() {
    Animation ani = new AlphaAnimation(1f, 0f);
    ani.setDuration(100);
    ani.setAnimationListener(new Animation.AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {

        }

        @Override
        public void onAnimationEnd(Animation animation) {
            Log.i(Tag, "hideSplash onAnimationEnd");
            if(animationDrawable != null){
                animationDrawable.stop();
                animationDrawable = null;
            }
            if (view != null) {
                mUnityPlayer.removeView(view);
                view = null;
            }
            if (bgView != null) {
                mUnityPlayer.removeView(bgView);
                bgView = null;
            }
        }

        @Override
        public void onAnimationRepeat(Animation animation) {

        }
    });
    bgView.startAnimation(ani);
}
