Android “网络视图视频事件”；onShowCustomView“；正在全屏播放，但当我回到小屏幕时，listner不起作用

webview视频事件“onShowCustomView”全屏启动，但当我回到小屏幕时，listner无法工作

当我全屏播放的时候。两种功能

onShowCustomView和onHideCustomView协同工作。当我试图回到小屏幕。函数的单位被调用

function onWebViewLoaded1(webargs, url) { 
    var page = webargs.object.page; 
    var webview = webargs.object;    
    var customViewContainer = view.getViewById(webview, 'singleimgpopup');
    var viewr = view;


var __extends = (this && this.__extends) || (function () {
    var extendStatics = function (d, b) {
        extendStatics = Object.setPrototypeOf ||
            ({ __proto__: [] } instanceof Array && function (d, b) { d.__proto__ = b; }) ||
            function (d, b) { for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p]; };
        return extendStatics(d, b);
    };
    return function (d, b) {
        extendStatics(d, b);
        function __() { this.constructor = d; }
        d.prototype = b === null ? Object.create(b) : (__.prototype = b.prototype, new __());
    };
})();
var MyWebChromeClient = /** @class */ (function (_super) {
    __extends(MyWebChromeClient, _super);
    function MyWebChromeClient() {

        var _this = _super.call(this) || this;
        return global.__native(_this);
    }
    MyWebChromeClient.prototype.onStop = function(){
        console.log("this");
    }
    MyWebChromeClient.prototype.onShowCustomView = function (view, callback) { 

         // Store the view and its callback for later (to kill it properly)
        if(this.mCustomView != null){
            callback.onCustomViewHidden(); return
        }
       this.mCustomView = view;
     //  webview.setVisibility(View.GONE);
       this.mCustomViewCallback = callback;
       console.log('fullscreen');
    };
    MyWebChromeClient.prototype.onHideCustomView = function () { 
         console.log("this2");
        _super.prototype.onHideCustomView.call(this);
        _super.prototype.mCustomView = null;
    };
    return MyWebChromeClient;
}(android.webkit.WebChromeClient));



    webview.android.getSettings().setJavaScriptEnabled(true);
    webview.android.getSettings().setAppCacheEnabled(true);
    webview.android.getSettings().setBuiltInZoomControls(true); 
    webview.android.getSettings().setSaveFormData(true);
     let myWebChromeClient = new MyWebChromeClient();
    webview.android.setWebChromeClient(myWebChromeClient); 

    // console.log("1=====================url",url);
    // webview.android.loadUrl(url); 
}

上面的方法可以工作，但我可以console.log（“放置全屏”）。 但是 当我点击下面给出的图标时，我无法在“退出全屏”上捕捉实例/事件/列表。我如何知道是否有人点击了下面给出的图标

这是nativescript videoplayer全屏按钮的代码。您需要更新videoplayer.android.js中的代码。有关详细信息，请询问我

var viewx=android.view.view； const view\u n=require（“tns核心模块/ui/core/view”）

我不确定将自定义视图添加到容器的确切位置。你能共用一个操场吗？

  var isFullScreen="";

            this.super.setAnchorView(view);

            //image button for full screen to be added to media controller

      this.super.getContext().getPackageName() );

           // fullScreen.setBackgroundResource("@drawable/icon");

           this.addView(fullScreen, params);
