我有这个代码,它的唯一的问题是,如果我离开WebView,甚至关闭该应用程序,甚至按下电源,播客的音频继续播放.

有人会知道如何阻止吗？

这是代码：

public class PodcastsActivity extends BaseActivity //implements ActionBar.OnNavigationListener

{

WebView webview = null;

@Override

public void onCreate(Bundle savedInstanceState)

{

//setTheme(R.style.Theme_Sherlock_Light);

super.onCreate(savedInstanceState);

//setContentView(R.layout.podcasts);

webview = new WebView(this);

webview.getSettings().setAppCacheEnabled(false);

webview.getSettings().setJavaScriptEnabled(true);

webview.setInitialScale(1);

webview.getSettings().setPluginState(PluginState.ON);

webview.setWebViewClient(new WebViewClient() {

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url);

return true;

}

});

//webSettings.setBuiltInZoomControls(true);

WebSettings webSettings = webview.getSettings();

webSettings.setJavaScriptEnabled(true);

webSettings.setBuiltInZoomControls(true);

//webSettings.getMediaPlaybackRequiresUserGesture();

webSettings.setAllowContentAccess(true);

webSettings.setEnableSmoothTransition(true);

webSettings.setLoadsImagesAutomatically(true);

webSettings.setLoadWithOverviewMode(true);

webSettings.setSupportZoom(true);

webSettings.setUseWideViewPort(true);

setContentView(webview);

webview.loadUrl("http://www.stitcher.com/podcast/entrepreneuronfirecom/entrepreneur-on-fire-tim-ferriss-other-incredible-entrepreneurs");

}

// public void onBackPressed ( )

// {

// Class.forName("com.***.HTML5WebView").getMethod("onPause", (Class[]) null).

// invoke(html5WebView, (Object[]) null);

// }

@Override

public boolean onKeyDown(int keyCode, KeyEvent event)

{

if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack())

{

webview.goBack();

return true;

}

return super.onKeyDown(keyCode, event);

}

@Override

public void onStop()

{

super.onStop();

// your code

webview.clearView();

}
