java - 在 Activity 之间传递整数值 - Android

Question

不幸的是，其他卡住的帖子无法帮助我。当我在选中简单单选按钮时单击按钮时，该应用程序停止工作。我无法去看其他 Activity 。

发送方:

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);
            }
        }
    });

接收方:

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