我测试了ArrayAdapter adapter=new ArrayAdapter(this,android.R.layout.simple_spinner_dropdown_item,android.R.layout.simple_dropdown_item_1line,list);
这句话有错，但是不知道错在哪里
------解决方案--------------------
将
ArrayAdapter adapter=new ArrayAdapter(this,android.R.layout.simple_spinner_dropdown_item,android.R.layout.simple_dropdown_item_1line,list);
改为:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, android.R.layout.simple_dropdown_item_1line, list);
或改为:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, list);
另外,建议发最新的yuyue.java全部内容和LogCat出错提示上来看看。
