Quick-cocos2d-x 小米 Mix 全面屏适配

有玩家反馈我们的游戏在 Mix 上面无法全屏显示, 上下会有黑边. 搜索了下, 网上还没有绍如何适配的相关文章, 这里介绍下我们是如何做的.

我们可以在看看小米官方 对全面屏适配工作的介绍 :

好的, 我们先按照官方的方法修改下 max_aspect 的值为 2 以上

<meta-dataandroid:name="android.max_aspect"android:value="2.1"/>

运行下, 发现顶部的黑条不见了, 但是底部的虚拟导航键还在. 我们接着看官方的文档:

然而这几种效果都不是我们想要的, 我们想要是隐藏 虚拟导航键 . Google 一下, 很容易搜索到这段代码:

/**
    * 隐藏虚拟按键，并且全屏
    */
   protected void hideBottomUIMenu(){
       //隐藏虚拟按键，并且全屏
       if (Build.VERSION.SDK_INT > 11 && Build.VERSION.SDK_INT < 19) { // lower api
           View v = this.getWindow().getDecorView();
           v.setSystemUiVisibility(View.GONE);
       } else if (Build.VERSION.SDK_INT >= 19) {
           //for new api versions.
           View decorView = getWindow().getDecorView();
           int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                           | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN;
           decorView.setSystemUiVisibility(uiOptions);
       }
   }

加上之后发现导航键真的没有了, 但是当你点击屏幕时, 它又出现了. 继续搜索发现了 这篇文章 , 按照文章中的提示进行修改你的 AppActivity :

    private Cocos2dxGLSurfaceView glSurfaceView;
    protected void onCreate(Bundle savedInstanceState, SplashEnum splash,long duration, boolean debug){
        ...
        View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
        int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);
        ...
    }
    @Override
    public Cocos2dxGLSurfaceView onCreateView(){
        glSurfaceView = super.onCreateView();
        this.hideSystemUI();
        return glSurfaceView;
    }
    @Override
    public void onWindowFocusChanged(boolean hasFocus)
    {
        super.onWindowFocusChanged(hasFocus);
        if (hasFocus)
        {
            this.hideSystemUI();
        }
    }
    private void hideSystemUI()
    {
        // Set the IMMERSIVE flag.
        // Set the content to appear under the system bars so that the content
        // doesn't resize when the system bars hide and show.
        glSurfaceView.setSystemUiVisibility(
                Cocos2dxGLSurfaceView.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | Cocos2dxGLSurfaceView.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | Cocos2dxGLSurfaceView.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | Cocos2dxGLSurfaceView.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                        | Cocos2dxGLSurfaceView.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                        | Cocos2dxGLSurfaceView.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
    }

搞定. 看下最终的效果:
