Android异常：requestFeature() must be called before adding content解决办法

错误代码：

protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);<span style="color:#ff0000;">this.requestWindowFeature(Window.FEATURE_NO_TITLE)</span>;this.setContentView(R.layout.main);}

正确代码：

protected void onCreate(Bundle savedInstanceState) {<span style="color:#ff0000;">this.requestWindowFeature(Window.FEATURE_NO_TITLE);</span>super.onCreate(savedInstanceState);this.setContentView(R.layout.main);}
