// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();

推荐答案
试试这个:
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setPluginState(WebSettings.PluginState.ON);
webview.getSettings().setMediaPlaybackRequiresUserGesture(false);
webview.setWebChromeClient(new WebChromeClient(){
// Need to accept permissions to use the camera
@Override
public void onPermissionRequest(final PermissionRequest request) {
Log.d("onPermissionRequest");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
request.grant(request.getResources());
}
}
});
