cocos creator打包原生加背景图片

cocos creator打包原生加背景图片，不然一开始会有黑屏的。

1. 改AndroidManifest.xml文件

   android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
   ->
   android:theme="@style/ImageSplashStyle"

2. 添加片背景主题

   <?xml version="1.0" encoding="utf-8"?>
   <resources >
    <style name="ImageSplashStyle"
           parent="@android:style/Theme.NoTitleBar.Fullscreen" >
        <item name="android:windowBackground" >@drawable/bg</item >
    </style >
   </resources >

3. 放bg图片在drawable文件夹

4. ts里面加hideNativeSplash，在场景价加载的时候发送

    hideNativeSplash() {
        if (cc.sys.os == cc.sys.OS_ANDROID && cc.sys.isNative) {
            jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "hideNativeSplash", "()V");
        } else if (cc.sys.os == cc.sys.OS_IOS && cc.sys.isNative) {
            jsb.reflection.callStaticMethod("AppHelper", "hideNativeSplash:", "");
        }
    }

5. 改AppActivity.java

   private static ImageView sSplashBgImageView = null;
   onCreate函数调用showNativeSplash();
   加这2个函数
    private static void showNativeSplash() {
        sSplashBgImageView = new ImageView(sapp);
        sSplashBgImageView.setImageResource(R.drawable.bg);
        sSplashBgImageView.setScaleType(ImageView.ScaleType.FIT_XY);
        sapp.addContentView(sSplashBgImageView,
                new WindowManager.LayoutParams(
                        FrameLayout.LayoutParams.MATCH_PARENT,
                        FrameLayout.LayoutParams.MATCH_PARENT
                )
        );
    }
    public static void hideNativeSplash() {
        sapp.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if (sSplashBgImageView != null) {
                    sSplashBgImageView.setVisibility(View.GONE);
                }
            }
        });
    }

   搞定！
