java - new View.OnClickListener(){} 类型中的 onClick(View, String) 方法永远不会在本地使用

Question

下面的这些代码用于使用 PRINCE 算法加密短信并将短信发送给接收者。目前我面临一个问题，其中 public void onClick(View v,String args) 给出错误消息“The method onClick(View, String) from the type new View.OnClickListener() {} 从未在本地使用”。我还提到了The method onClick(View) from the type new Thread(){} is never used locally但给出的解决方案对我没有帮助。对于这个问题还有其他解决方案吗？

    btnSendSMS.setOnClickListener(new View.OnClickListener()
    {
    @Override
    public void onClick(View v) {
        String phoneNo = txtPhoneNo.getText().toString();
         String message = txtMessage.getText().toString();
         if (phoneNo.length()>0 && message.length()>0)
         {
              LongBuffer messageBuf = TooLong.messageToLongBuffer(message);
              messageBuf.flip();
              long[] messageData = new long[messageBuf.remaining()];
              LongBuffer i = messageBuf.get(messageData);
              String v1=prince.Encrypt(i, k0, kop, k1, t);
              sendSMS(phoneNo, v1);
          }
          else
               Toast.makeText(getBaseContext(),

Answer 1

onClick() 方法的签名是 onClick(View)，而不是 onClick(View,String)。后者声明了一个从未被调用的新方法，并且不会覆盖 OnClickListener 接口(interface)中的方法。

从方法中删除 String 参数，并删除另一个 stub onClick(View)。
