public static class CharacteristicDialog extends DialogFragment {
        int mNum;

        static CharacteristicDialog newInstance(int num) {
            CharacteristicDialog f = new CharacteristicDialog();            
            Bundle args = new Bundle();
            args.putInt("num",num);
            f.setArguments(args);
            return f;
        }

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            mNum = getArguments().getInt("num");
            setStyle(STYLE_NO_INPUT,0);        
        }

        @Override
        public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
            View v = inflater.inflate(R.layout.characteristic_dialog,container,false);
            v.setOnClickListener(new OnClickListener() {                
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
    }

我在我的主片段中创建它,如下所示：

DialogFragment newFragment = CharacteristicDialog.newInstance(v.getId());
        newFragment.setShowsDialog(true);
        newFragment.show(getFragmentManager(),"dialog");

它显示得很好,但它不是模态的(我可以点击两侧并在对话框后面的主片段上进行操作).

我如何制作模态？

谢谢
