本文介绍了在Android开发中遇到的DialogFragment样式应用问题，并提供了三种解决方案：尝试通过设置style、在onStart中调整窗口属性以及最终推荐的方法——利用V7兼容包来实现自定义样式。

方法一：设置style -- 无效

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View view = inflater.inflate(R.layout.dialog_confirm_layout, null);

        TextView descTextView = (TextView) view.findViewById(R.id.dialog_content_tv);
        descTextView.setText("Android 4.2 DialogFragment");

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.CustomDialog);
        builder.setView(view);
        return builder.create();
    }

方法二：在onStart中设置 -- 无效

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View view = inflater.inflate(R.layout.dialog_confirm_layout, null);

        TextView descTextView = (TextView) view.findViewById(R.id.dialog_content_tv);
        descTextView.setText("Android 4.2 DialogFragment");

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setView(view);
        return builder.create();
    }

    @Override
    public void onStart() {
        super.onStart();

        Window window = getDialog().getWindow();
        WindowManager.LayoutParams windowParams = window.getAttributes();
        windowParams.dimAmount = 0.0f;
        window.setAttributes(windowParams);
    }
