现在在案例R.Id.b_save的on Click功能上：在案例R.id.b_cancel和案例R.id.b_reset中，给出错误"Cannot be resolved or is not a field"。我已经清理了项目并重新启动它，并且正在使用Eclipse，这是当我在与该项目相关的另一个类中使文本视图可单击时遇到的相同错误，可能的解决方案是什么？我已经尽力了，我可以在目录中看到R.Java文件

谢谢！

Answer 1

您已使用

case R.id.b_save:


        break;

    case R.id.b_cancel:


        break;

    case R.id.b_reset:

您应该使用

case R.id.savebutton:


        break;

    case R.id.cancelbutton:


        break;

    case R.id.resetbutton:

:)希望您有想法

Answer 2

这里是答案：

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch(v.getId()) {

    case R.id.savebutton:


        break;

    case R.id.cancelbutton:


        break;

    case R.id.resetbutton:


        break;



    }
}
