如何在android中设置滚动视图

Question

    RelativeLayout blur = (RelativeLayout) findViewById(R.id.relative5);
    TextView name_tv = new TextView (this);
    name_tv.setText("\n\n   First Name");
    blur.addView(name_tv);
    Typeface font=Typeface.SERIF;
    name_tv.setTypeface(font);

    final EditText nameedit = new EditText(this);
    nameedit.setHint("First name");
    blur.addView(nameedit);
    Typeface font33=Typeface.SERIF;
    nameedit.setTypeface(font33);
    nameedit.setMaxLines(1);
    nameedit.setImeOptions(EditorInfo.IME_ACTION_NEXT);
    nameedit.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);

同样地，我在这个类中动态添加了几个文本视图和编辑文本。问题是当我在xml中添加scrollview时它显示错误.....
