DialogFragment使用

1.布局中设置padding 如何不设置会被覆盖无法显示圆角

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        //去掉标题
        getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
        //设置背景  圆角
        getDialog().getWindow().setBackgroundDrawableResource(R.drawable.background);
        View view = inflater.inflate(R.layout.news_webview,  container, false);
        WebView news_webview= (WebView) view.findViewById(R.id.news_webview);
        news_webview.getSettings().setJavaScriptEnabled(true);
        news_webview.loadUrl(loadUrl);
        return view;
    }

    @Override
    public void onStart() {
        super.onStart();
        Dialog dialog=getDialog();
        if (dialog!=null){
            /**
             * 设置dialog的大小
             */
            DisplayMetrics dm = new DisplayMetrics();
            getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);
            dialog.getWindow().setLayout((int) (dm.widthPixels * 0.6), (int) (dm.heightPixels*0.7));
        }
    }
