MainActivity.class:
ActionBar actionBar = this.getActionBar();
actionBar.setDisplayOptions(ActionBar.DISPLAY_HOME_AS_UP, ActionBar.DISPLAY_HOME_AS_UP);
actionBar.setDisplayHomeAsUpEnabled(false);// 隱藏返回上級的箭頭
actionBar.setHomeButtonEnabled(false);//沒有點擊效果
actionBar.setBackgroundDrawable(this.getResources().getDrawable(R.drawable.drawable_white));//設置背景
