java - "The value of the local variable SoundButton38 is not used"但我想使用它？

Question

我是编程新手，我正在 eclipse 中编程。

我正在创建一个简单的音板，但收到警告“未使用局部变量 SoundButton38 的值”，但我想使用该变量。

SoundButton1-37 正在工作并且没有错误，但 38-63 确实有警告。我不确定是什么原因造成的以及为什么会发生。

这是我的代码 fragment ，其中出现警告(35、36 和 37 没有警告:

            Button SoundButton35 = (Button)findViewById(R.id.sound35);
            SoundButton35.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            mSoundManager.playSound(35);

        }
    });
            Button SoundButton36 = (Button)findViewById(R.id.sound36);
            SoundButton36.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            mSoundManager.playSound(36);

        }
            });

            Button SoundButton37 = (Button)findViewById(R.id.sound37);
            SoundButton35.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            mSoundManager.playSound(37);

        }
    });

            Button SoundButton38 = (Button)findViewById(R.id.sound38);
            SoundButton35.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            mSoundManager.playSound(38);

        }
    });

这是我的代码的开头

感谢您的帮助，我无法找到一个好的答案。

Answer 1

 Button SoundButton38 = (Button)findViewById(R.id.sound38);
            SoundButton35.setOnClickListener(new OnClickListener() {

这里好像有错字，我认为应该是

 SoundButton38.setOnClickListener(new OnClickListener() { 

类似

 Button SoundButton37 = (Button)findViewById(R.id.sound37);
            SoundButton35.setOnClickListener(new OnClickListener() {

应该是

SoundButton37.setOnClickListener(new OnClickListener() {
