Question

我是android新手，我第一次使用webview，片段，抽屉......

我遇到的问题是，在视频中按全屏后我的代码崩溃了。我不知道出了什么问题......

WebViewFragmentVideos

    public class WebViewFragmentVideos extends Fragment {
    WebView webView;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        // Retrieving the currently selected item number
        int position = getArguments().getInt("position");

        String url = getArguments().getString("url");

        // List of rivers
        String[] menus = getResources().getStringArray(R.array.Websitesenglish);

        // Creating view corresponding to the fragment
        View v = inflater.inflate(R.layout.fragment_layout, container, false);

        // Updating the action bar title
        getActivity().getActionBar().setTitle(menus[position]);

        //Initializing and loading url in webview
        webView = (WebView)v.findViewById(R.id.webView);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setLoadsImagesAutomatically(true);
        webView.getSettings().setBuiltInZoomControls(true);
        webView.loadUrl(url);
        webView.setWebChromeClient(new MyChromeClient());

        webView.setWebViewClient(new WebViewClient(){


            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url){
              view.loadUrl(url);
              return true;
            }

        });
        return v;}

class MyChromeClient extends WebChromeClient {
    String url = getArguments().getString("url");
    @Override
    public void onShowCustomView(View view, CustomViewCallback callback) {

        Intent intent = new Intent(null, LandVideoAct.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.putExtra("video", url);
        startActivity(intent); 
}
    }
        }

和的 LandVideoAct

    public class LandVideoAct extends Activity {
    WebView webView, fullweb;
    String url = "";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setTheme(android.R.style.Theme_Light_NoTitleBar_Fullscreen);
        setContentView(R.layout.landfull);
        url = getIntent().getStringExtra("video") + "?fs=1";
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        webView = (WebView) findViewById(R.id.fullwebview);

        if (Build.VERSION.SDK_INT < 8) {
            webView.getSettings().setPluginsEnabled(true);
        } else {
            webView.getSettings().setPluginState(PluginState.ON);
        }
        webView.getSettings().setJavaScriptEnabled(true);
        webView.setWebChromeClient(new WebChromeClient() {
            @Override
            public void onShowCustomView(View view, CustomViewCallback callback) {
                LandVideoAct.this.finish();
            }
        });
        webView.loadUrl(url);

}}

我希望你的家伙可以帮我解决我的问题。谢谢!!

这段代码在android中是不允许的。

Intent intent = new Intent(null, LandVideoAct.class);

遇到崩溃问题。它主要是因为上面的代码行。当调用webview中的全屏视频时，它会调用android系统即onShowCustomView(View view, CustomViewCallback callback)。你上面的代码行失败的地方。而不是使用活动上下文或应用程序上下文

 Intent intent = new Intent(context, LandVideoAct.class);

为什么我的全屏幕崩溃了？
