[游戏开发]Unity打包成Android后打开后会黑屏一段时间 2.0

Unity打包成Android后打开后会黑屏一段时间这个版本在有悬浮窗会出问题！
解决方案
思路就是在android 启动时，先加载一个ImageView 盖在最上层遮挡住启动动画，
后面等Unity 启动好了后再关闭道具这个遮挡的ImageView。
1.创建一个ImageView ,在android 启动时调用

    // Setup activity layout
    @Override protected void onCreate(Bundle savedInstanceState)
    {
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);
        mUnityPlayer = new UnityPlayer(this);
        UnitySplashSDK.getInstance().SetmUnityPlayer(mUnityPlayer);
        setContentView(mUnityPlayer);
        mUnityPlayer.requestFocus();
 		//调用启动页面
        UnitySplashSDK.getInstance().onShowSplash();
    }

    public void onShowSplash() {
        if (bgView != null)
            return;
        try {
            Log.e("==========", "onShowSplash: 1 "  );
            // 设置启动内容，这里的内容可以自定义区修改，这里我加载了一个gif作为启动图标↓
            bgView = new ImageView(UnityPlayer.currentActivity);
            bgView.setBackgroundColor(Color.parseColor("#ffffffff"));
            bgView.setImageResource(R.drawable.logo1);
//            bgView.setScaleType(ImageView.ScaleType.CENTER);
            bgView.setAdjustViewBounds(false);
            bgView.setScaleType( ImageView.ScaleType.CENTER_CROP);
            mUnityPlayer.addView(bgView);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

2.等待Unity 启动完成

    // 在unity的Activity中暴露方法给unity，让unity在准备好内容后调用隐藏启动画面
    public void onHideSplash() {
        try {
            if (bgView == null)
                return;
            UnityPlayer.currentActivity.runOnUiThread(new Runnable() {
                public void run() {
                    mUnityPlayer.removeView(bgView);
                    bgView = null;
                }
            });
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // 这是启动画面的图片，这里可以使任意一个View，可以根据自己的需要去自定义
    private ImageView bgView = null;
    private UnityPlayer mUnityPlayer = null;
    private static UnitySplashSDK mInstance;
    public static UnitySplashSDK getInstance() {
        if (null == mInstance) {
            synchronized (UnitySplashSDK.class) {
                if (null == mInstance) {
                    mInstance = new UnitySplashSDK();
               }
            }
        }
        return mInstance;
    }
	public  void  SetmUnityPlayer( UnityPlayer pl){
	    mUnityPlayer=pl;
	}

    public void onShowSplash() {
        if (bgView != null)
            return;
        try {
            Log.e("==========", "onShowSplash: 1 "  );
            // 设置启动内容，这里的内容可以自定义区修改，这里我加载了一个gif作为启动图标↓
            bgView = new ImageView(UnityPlayer.currentActivity);
            bgView.setBackgroundColor(Color.parseColor("#ffffffff"));
            bgView.setImageResource(R.drawable.logo1);
            bgView.setAdjustViewBounds(false);
            bgView.setScaleType( ImageView.ScaleType.CENTER_CROP);
            mUnityPlayer.addView(bgView);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    // 在unity的Activity中暴露方法给unity，让unity在准备好内容后调用隐藏启动画面
    public void onHideSplash() {

        try {
            if (bgView == null)
                return;
            UnityPlayer.currentActivity.runOnUiThread(new Runnable() {
                public void run() {
                    mUnityPlayer.removeView(bgView);
                    bgView = null;
                }
            });
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
