    }

    new FrameLayout.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

}

我创建了一个类来实现上面的html5..检查包i下面的代码；

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;

public class TestHTML5WebView extends Activity {

HTML5WebView mWebView;

String url="http://www.ustream.tv/embed/10464044";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mWebView = new HTML5WebView(this);

    if (savedInstanceState != null) {
           mWebView.restoreState(savedInstanceState);//http://www.ustream.tv/KTNKENYALIVE///http://youtu.be/Mmry0Bdj9Vg
    } else {    
        mWebView.loadUrl(url);
    }

    setContentView(mWebView.getLayout());
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    mWebView.saveState(outState);
}

@Override
public void onStop() {
    super.onStop();
    mWebView.stopLoading();
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        if (mWebView.inCustomView()) {
            mWebView.hideCustomView();
            return true;
        }
    }
    return super.onKeyDown(keyCode, event);
}

}
