Question

我正在将一个HTML字符串传递给我的Fragment。它将它加载到WebView中但没有任何反应，片段仍为空。

我非常肯定（感谢日志）我的Fragment正在接收HTML字符串。

这是片段代码：

private WebView mWebView;
String html;

@Override
public void onCreate(Bundle savedInstanceState) {
    Log.d(MainActivity.TAG, "VideogamesWebViewFragment --> onCreate()");
    super.onCreate(savedInstanceState);
}

public void onActivityCreated(Bundle savedInstanceState)
{
    Bundle bundle = this.getArguments();
    if(bundle != null)
    {
        html = bundle.getString("html");
    }

super.onActivityCreated(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    Log.d(MainActivity.TAG, "VideogamesWebViewFragment --> onCreateView()");
    View view = inflater.inflate(R.layout.default_web_view, container,
            false);
    mWebView = (WebView) view.findViewById(R.id.webview);   
    mWebView.getSettings().setLoadsImagesAutomatically(true);         
    //load html string   
    mWebView.loadData(html, "text/html", null);  

    return view;
}

@Override
public void onDestroy() {
    Log.d(MainActivity.TAG, "VideogamesWebViewFragment --> onDestroy()");
    super.onDestroy();
}

@Override
public void onDestroyView() {
    Log.d(MainActivity.TAG, "VideogamesWebViewFragment --> onDestroyView()");
    super.onDestroyView();
}

@Override
public void onResume() {
    super.onResume();
    Log.d(MainActivity.TAG, "VideogamesWebViewFragment --> onResume()");
}

@Override
public void onViewStateRestored(Bundle savedInstanceState) {
    super.onViewStateRestored(savedInstanceState);  
    Log.d(MainActivity.TAG,"VideogamesWebViewFragment --> onViewStateRestored()");
}

我也遇到了这些错误：

Answer 1

不要关心从logcat获得的错误。

就我而言，我加载了一个包含图像滑块的网站。当滑块中的图像更改图像时，logcat会生成相同的错误代码。我认为可能是因为网页计算了我的设备屏幕的大小。我只是因为它来自gl，我不确定..

05-03 10：15：25.149：E / eglCodecCommon（5081）：错误未知类型0x1（glSizeof，73）

但它不再给我的应用带来麻烦。

onCreateView可以在onActivityCreated之前或之后调用，具体取决于您添加片段的方式。尝试在onResume或onStart

中加载HTML

Fragment中的WebView不加载HTML字符串
