Question

我用两个Activity创建一个android应用程序。我的第二个Activity包含一个youtube视频嵌入。当我启动此活动并运行此视频时，它可以正常运行。但当我关闭我的活动时，如果我的视频正在播放，我的活动已经关闭，但我听到了我的视频。我认为我的视频并没有真正关闭，而且她正在背景中播放。

你可以帮帮我吗？

谢谢！

编辑：我在MyActivity中构建了一个测试，我遇到了同样的问题。

public class MyActivity extends Activity implements MBAdListener{

private FrameLayout layout;

/**
 * Called when the activity is first created.
 */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    RelativeLayout adViewContainer = (RelativeLayout) findViewById(R.id.adView);
    layout = new FrameLayout(this);

    layout.setLayoutParams(new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT,
            ViewGroup.LayoutParams.FILL_PARENT,
            Gravity.CENTER)
    );
    layout.setBackgroundColor(Color.BLUE);
    setContentView(layout);
    WebView content = new WebView(this);
    content.setLayoutParams(new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT,
            ViewGroup.LayoutParams.FILL_PARENT,
            Gravity.CENTER
    ));
    content.setHorizontalScrollBarEnabled(false);
    content.setVerticalScrollBarEnabled(false);
    content.getSettings().setJavaScriptEnabled(true);
    content.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    content.getSettings().setBuiltInZoomControls(false);
    content.getSettings().setSupportZoom(true);
    content.getSettings().setUseWideViewPort(true);
    content.getSettings().setPluginsEnabled(true);
    content.getSettings().setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
    content.getSettings().setSavePassword(true);
    content.getSettings().setSaveFormData(true);
    content.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

    layout.addView(content);

    content.loadData("<iframe width=\"320\" height=\"200\" src=\"http://www.youtube.com/embed/vCXRt0kQvUE?autoplay=1\" frameborder=\"0\" allowfullscreen></iframe>", "text/html", "UTF-8");

}

@Override
public void onPause() {
  super.onPause();

  try {
    Class.forName("android.webkit.WebView")
      .getMethod("onPause", (Class[]) null)
      .invoke(webview, (Object[]) null);
  } catch(ClassNotFoundException cnfe) {
