为android创建微调器时出错？

Question

嘿所以我正在尝试创建一个具有不同选项的微调器，并且我不断为最后两行得到这两个错误。我正在关注http://developer.android.com/guide/topics/ui/controls/spinner.html#Populate，所以我不确定为什么会出现错误？

//Creating spinner for select/options
    Spinner spinner = (Spinner) findViewById(R.id.typeFieldWardrobeScreen);

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,  R.array.type_array, android.R.layout.simple_spinner_item);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

//for line above
Multiple markers at this line
        - Syntax error on token "setDropDownViewResource", Identifier expected after this token
        - Syntax error on token ".", ... expected

    spinner.setAdapter(adapter);

 //for line above
 Multiple markers at this line
    - Syntax error on token(s), misplaced construct(s)
    - Syntax error on token "adapter", VariableDeclaratorId expected after

我没有意识到我在onCreate方法之外有它，并且它不能在方法之外。
