的WebView必须装载两次，以正确加载 [英] WebView must be loaded twice to load correctly

问题描述

在与第一web视图加载网页，有时图像丢失或显示不正确。如果我重新加载页面web视图总是显示完美。我知道，大家首先会想到我设置Javascript使用loadURL后，但事实并非如此。

When the page with the WebView first loads, sometimes images are missing or displayed incorrectly. If I reload the page the WebView always displays perfectly. I know everyone will first think I set javascript after loadUrl, but that isn't true.

在我的onCreate有：

In onCreate I have:

learnWebView = (WebView)findViewById(R.id.learnWebView);
learnWebView.setWebViewClient(new WebViewClient());
learnWebView.getSettings().setJavaScriptEnabled(true);

然后在后面的onCreate后调用该函数我有：

Then later in the function called after onCreate I have:

learnWebView.loadUrl("myurl");

是的，我知道，与使用loadURL该功能后的onCreate每次调用。

And yes, I know that the function with loadUrl is called after onCreate every time.

推荐答案

我没有在 WebViewClient shouldOverrideUrlLoading code>

I haven't seen this issue since overriding shouldOverrideUrlLoading in WebViewClient

learnWebView.getSettings().setJavaScriptEnabled(true);
learnWebView.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        return false;
    }
});

虽然我不确定为什么这会有所作为，因为返回false只是应该让你的的WebView 处理所有URL的开口。

Although I'm uncertain as to why this would make a difference, because returning false is just supposed to make your WebView handle all url openings.
