活動之間傳遞整數值 - Android

Question

不幸的是，其他卡住的帖子不能幫助我。 當我點擊按鈕，而簡單的單選按鈕被選中時，應用程序停止工作。我無法去看另一個活動。

發送方：

btn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      if(radiobutton_arm_triceps_easy.isChecked()) { 
       String dene = "my example test"; 
       int myValue=2; 
       Intent intent = new Intent(getApplicationContext(), exercise_arm_triceps_execute.class); 
       intent.putExtra("attempt1", myValue); 
       startActivity(intent); 
      } 
     } 
    }); 

接收側：

int receiveValue=getIntent().getIntExtra("attempt1",0); 
    textshow.setText(receiveValue); 

logcat的
