Java Eclipse for Android应用程序中的语法错误

我想我疯了，Eclipse抛出了这些错误“语法错误，插入”；“要完成语句”“语法错误，插入”）“要完成表达式”“语法错误，插入“}”来完成类体”“语法错误，插入“}”来完成方法体”“我似乎不明白为什么

问：有人能找出语法错误在哪里，或者为什么Eclipse会说有错误吗

注：该代码的目的是在按下按钮后使用参考更改按钮上的文本：

这些错误是在我添加以下代码行后出现的：

/** Called when user clicks Start */
public void sendStart(View view) {
    // Do something in response to button
     final Button b_start = (Button) findViewById(R.id.b_start);
     b_start.setTag (1);
     b_start.setOnClickListener( new View.OnClickListener() {

    public void onClick(View v) {
    final int status =(Integer) v.getTag();
     if(status == 1) {
         b_start.setText("Stop");
         v.setTag(0); 
     } else {
         b_start.setText("Start");
         v.setTag(1); 
     }

    }

整个类别代码如下所示：

您缺少

setOnClickListener

的结束符

}）

：

b_start.setOnClickListener( new View.OnClickListener() {
    public void onClick(View v) {
        final int status =(Integer) v.getTag();
        if(status == 1) {
            b_start.setText("Stop");
            v.setTag(0); 
        } else {
            b_start.setText("Start");
            v.setTag(1); 
        }
    }
});

谢谢，还需要在最后一个括号之前再添加一个“}”当发生这种情况时，请使用eclipse格式化程序格式化代码并帮助您查找缺少的括号eclipse会告诉您语法错误在哪里。你可能认为这些信息不足以解决问题，但如果不提供这些信息，你就是在要求人们用比你更少的信息来解决问题。9月19日21:11回答。提供足够的信息。仅仅因为有人读懂了你的想法，或者出于善意决定复制你的整个项目并自己调试，并不意味着这是一个好问题。读懂你的想法是不可能的。问题在6分钟内回答，没有足够的时间复制和粘贴项目。如果您无法用提供的信息解决问题，请不要回答。eightx2能够。
