我的FCL文件在res文件夹中。函数块的名称是heart，输出变量是angin，代码段是

    public void onClick(View v) {
                // Setting the variables values

                EditText enteredrestpress = (EditText) findViewById(R.id.editTextrestingpress)  ;

                EditText maxrate = (EditText) findViewById(R.id.editTextmaxrate) ;
                EditText restrate = (EditText) findViewById(R.id.editTextrestrate) ;

                String  strrestingpress = enteredrestpress.getText().toString();
                int numrestingpress= Integer.parseInt(strrestingpress);

                String  strcholeserum = choleserum.getText().toString();

                String  strrestrate = restrate.getText().toString();

                Log.d("taha", "Completed");

                }


            }


        });

请帮我解决这个错误谢谢
