为什么我的微调器运行onItemSelected它连接到即使它点击？

Question

我正在尝试在我的一个活动中添加一个微调器，我可以从一组字段中动态地向微调器添加项目，这样当我点击该微调器中的一个项目时，它会重新填充这些字段。将字段中的项添加到侦听器工作正常，但是当我尝试单击微调器以重新填充字段时。它仍然是一项正在进行中的工作，因此存在过多的代码。

这是正在运行的类的代码

Answer 1

    @Override
    public void onItemSelected(AdapterView<?> parent, View v, int position, long id) {
                //you should be switching on the view, since the class is implementing onItemSelectedListenter
        switch(v.getId()){
            case (R.id.spinner):
                //logic for setting mEdit1.setText(teamNumber), etc..
            break;
        }
}

由于您为活动实现了onItemSelectedListener，因此必须设置表单对象在选中时应执行的操作的情况。说你有另一个旋转器。该微调器也将this作为设置onItemSelectedListener的arg。应用程序无法知道每个实例应该做什么，除非它知道选择了哪个view。
