　　錯誤提示見紅字部分

錯誤的代碼

1     protected void onCreate(Bundle savedInstanceState) {
2         this.setContentView(R.layout.setup_info_page);
3         this.requestWindowFeature(Window.FEATURE_NO_TITLE);//           Activity去掉標題
4     super.onCreate(savedInstanceState);
5     }

這里 this.setContentView(R.layout.setup_info_page)比

this.requestWindowFeature(Window.FEATURE_NO_TITLE)方法調用更早，所以報錯了。

只需要保證setContentView方法在requestWindowFeature方法之后執行就可以了。
