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));
}
}
