Question

Webview正确启动并运行。但是如果我使用滑动刷新WebView，应用程序将关闭。请帮我。谢谢。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    mySwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh_layout);

    mySwipeRefreshLayout.setColorSchemeResources(R.color.quogito_color);

    WebView myWebView = (WebView) findViewById(R.id.webview);

    WebSettings webSettings = myWebView.getSettings();

    webSettings.setJavaScriptEnabled(true);

    webSettings.setLoadsImagesAutomatically(true);

    MyWebViewClient myWebViewClient = new MyWebViewClient();

    myWebView.setWebViewClient(myWebViewClient);

    myWebView.loadUrl(website_url);

    mySwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            mySwipeRefreshLayout.setRefreshing(true);
            refreshPage();
        }
    });
    this.onStart();
}

你没有在oncreate方法上初始化你的“myWebView”，你应该这样做......

 myWebView = (WebView) findViewById(R.id.XXXXX);

刷新刷新时，Android webview强制关闭
