单击按钮时出错
单击按钮时出错
提问于 2013-11-11 11:28:02
我按下按钮时出了问题
如果有人能帮我，我真的很感激
public class submit implements Button.OnClickListener {
@Override
public void onClick(View v) {
no = " "+noper.getText();
na = " "+nama.getText();
if (rb1.isChecked())
j = " Male ";
if (rb2.isChecked())
j = " Female ";
ag = (String) agamalist.getSelectedItem();
tl = (String) Spinner01.getSelectedItem() + "-"
+ (String) Spinner02.getSelectedItem() + "-"
+ (String) Spinner03.getSelectedItem();
ju = "";
if (c1.isChecked())
ju += " TK ";
if (c2.isChecked())
ju += " SI ";
if (c3.isChecked())
ju += " TE ";
t1.setText(no);
t2.setText(na);
t3.setText(j);
t4.setText(ag);
t5.setText(tl);
t6.setText(ju);
tabHost.setCurrentTab(1);
}
}程序启动正确，但当我按下按钮，这只是不幸和关闭我的程序。
这是一只原木猫

天哪..。你为什么要创造一整堂课..？
你也可以用一种简短而甜蜜的方法来做这件事。
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// do your work here
}
});Stack Overflow用户

您的类应该实现View.OnClickListener，实现抽象方法OnClick来执行您想做的任何事情。在onCreate()方法中，还将侦听器设置为按钮：
