Android 如何将微调器值获取到post窗体
我制作了这个代码,这样我就可以将信息发送到我的网站。只是现在我想从我尝试过的微调器加载类别: String mCategory=category.getItemAtPosition(在这里放什么?).toString() 我只是不知道怎么做,我希望有人知道Android 如何将微调器值获取到post窗体,android,string,post,spinner,Android,String,Post,Spinner,我制作了这个代码,这样我就可以将信息发送到我的网站。只是现在我想从我尝试过的微调器加载类别: String mCategory=category.getItemAtPosition(在这里放什么?).toString() 我只是不知道怎么做,我希望有人知道 net.thinkbin; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.i
