本文介绍如何在Cocos2dx中实现Android 4.4及以上系统的沉浸式模式，通过修改AppActivity代码来隐藏系统状态栏和导航栏，并保持内容在系统栏隐藏和显示时不变形。此外，还提供了在全屏输入法开启和键盘关闭时维持沉浸式状态的方法。

环境：quick-cocos2dx-community 3.6.5

只有在Android 4.4及以上系统才支持沉浸式模式，修改 AppActivity代码如下：

    @Override
    public Cocos2dxGLSurfaceView onCreateView() {

        Cocos2dxGLSurfaceView glSurfaceView = super.onCreateView();

        hideSystemUI();

        return glSurfaceView;
    }

    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        if (hasFocus && Build.VERSION.SDK_INT >= 19) {

            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.
        if (Build.VERSION.SDK_INT >= 19)
        {
            Cocos2dxGLSurfaceView decorView =Cocos2dxGLSurfaceView.getInstance();
            decorView.setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                            | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
        }

    }

另外如果打开了全屏的输入法时，需要再次做隐藏处理，在Cocos2dxEditBoxHelper.java createEditBox中失去焦点的回调中添加：

editBox.setOnFocusChangeListener(new View.OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
...


//全屏设置
                            if (Build.VERSION.SDK_INT >= 19) {
                                Cocos2dxActivity cocosAct=(Cocos2dxActivity)Cocos2dxActivity.getContext();
                                Cocos2dxGLSurfaceView view=cocosAct.getGLSurfaceView();
                                view.setSystemUiVisibility(
                                        View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                                                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                                                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                                                | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                                                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
                            }

在Cocos2dxGLSurfaceView.java protected void initView() 中关闭键盘的回调中添加：

case HANDLER_CLOSE_IME_KEYBOARD:
                        ...//全屏设置
                            if (Build.VERSION.SDK_INT >= 19)
                            {
                                setSystemUiVisibility(
                                        View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                                                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                                                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                                                | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                                                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
                            }
                        }
                        break;
