怎么设置默认选中

panyancen · 2018-10-11T06:09:21Z

继承后，加个类 public void setpos(int current_tab_position){
this.current_tab_position=current_tab_position;
}，然后在调用这个控件的actvity里写：mDropDownMenu.setpos(0);
mDropDownMenu.setTabText(type_pos == 0 ? headers[0] :types[type_pos]);
mDropDownMenu.closeMenu();

mDropDownMenu.setTabText(type_pos == 0 ? headers[0] :types[type_pos]);
mDropDownMenu.closeMenu();

这样做还是不可以默认选中啊。。。

可以的，你继承后，把DropDownMenu.class类的代码全部复制到你的自定义的类，然后在你自定义的类加我给你的方法。我已经实现了，你可以看看DropDownMenu.class里的代码，理解一下就可以了

我是直接在DropDownMenu的源码里面加的你的方法setTabText方法还是不生效

current_tab_position这个值，要点击控件才不是-1，所以我们使用的时候，传值给它

yu1183688986 · 2018-10-12T01:10:27Z

的
谢谢你，直接在源码中添加你的方法也是可行的，难道我昨晚加班懵逼了，昨晚不行，今天就可以了。
/** * 改变对应位置tab标签文字 */ public void setTabText(int position, String text) { current_tab_position = position; if (null != tabMenuView.getChildAt(current_tab_position)) { getTabTextView(tabMenuView.getChildAt(current_tab_position)).setText(text); } }
