Android 单击时出现按钮错误

我按下按钮时有问题

如果有人能帮助我，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，但当我按下按钮时，不幸的是，它关闭了我的程序

您的类应该实现View.OnClickListener，实现抽象方法OnClick来执行任何您想要的操作。在onCreate（）方法中，还将侦听器设置为按钮：

myButton.setOnClickListener(this);

天哪。。。你为什么要创建一个完整的类

你也可以用一种简短的方法来做这件事

btn.setOnClickListener(new OnClickListener() {
     @Override
     public void onClick(View v) {
          // do your work here
     }
});

你能发布stacktrace吗？问题可能在任何地方。发布logcatuse no=“”+noper.getText（）.toString；“na”也一样
