Android Dialog彈窗提示，在4.4.4和5.1中會默認顯示Dialog的title

在項目中fragment用到Dialog做一個不帶標題的提示，準確講是一個功能的使用說明。在4.4.4和5.1中會默認顯示空白title。

 private void showProduceDialog() {
      

        Dialog dialog = new Dialog(getContext());
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉標題
        dialog.getWindow().setBackgroundDrawableResource(R.drawable.produce_backgroud);
        View view = getActivity().getLayoutInflater().inflate(R.layout.produce_dialog_layout, null);
        dialog.setContentView(view);

        final TextView tvTitle = (TextView) view.findViewById(R.id.produce_content);
        
        tvTitle.setText(R.string.vibration_indroduce_text);
    
        Window dialogWindow = dialog.getWindow();
        WindowManager.LayoutParams lp = dialogWindow.getAttributes();
        dialogWindow.setGravity(Gravity.CENTER )

        /*
         * 將對話框的大小按屏幕大小的百分比設置
         */
        WindowManager m = getActivity().getWindowManager();
        Display d = m.getDefaultDisplay(); // 獲取屏幕寬、高用
        WindowManager.LayoutParams p = dialogWindow.getAttributes(); // 獲取對話框當前的參數值
        p.height = (int) (d.getHeight() * 0.45); // 高度設置爲屏幕的0.6
        p.width = (int) (d.getWidth() * 0.6); // 寬度設置爲屏幕的0.65
        dialogWindow.setAttributes(p);
        dialog.show();

    }

//添加到Dialog的佈局文件
