我读过人们说要通过清理项目来解决这个问题，但我已经尝试了两次而且它没有帮助。我还创建了另一个项目并复制了代码，所以我觉得它有所不同。任何帮助表示赞赏。

第36行

txtBPM1.setText(120, TextView.BufferType.EDITABLE);

Answer 1

当您访问某些控件或您在活动onCreate中传递setContentView(R.layout.your_layout);的布局中不存在该控件时，会发生此错误。只是检查你正在使用的所有id，字符串和其他控件是否属于相同的布局

Answer 2

（您在MainActivity.java:line 36中的错误（它是导入生成的R）） 1.从导入中删除错误行并在红色R.id上使用弹出消息。 * * 2.关闭并重新打开IDE

Answer 3

将120更改为如此字符串：

txtBPM1.setText(""+120, TextView.BufferType.EDITABLE);
