requestFeature() must be called before adding content 错误

public void onCreate(Bundle savedInstanceState) {

           super.onCreate(savedInstanceState);

           setContentView(R.layout.tab_choice);

     requestWindowFeature(Window.FEATURE_NO_TITLE);

}

public void onCreate(Bundle savedInstanceState) {

           super.onCreate(savedInstanceState);

           setContentView(R.layout.tab_choice);

     requestWindowFeature(Window.FEATURE_NO_TITLE);

}

其中: setContentView(R.layout.tab_choice);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

两行顺序换一下就可以了。

改后：

public void onCreate(Bundle savedInstanceState) {

           super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

           setContentView(R.layout.tab_choice);

}

其中: setContentView(R.layout.tab_choice);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

改后：

public void onCreate(Bundle savedInstanceState) {

           super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

           setContentView(R.layout.tab_choice);

}
