ndroid ntent-Android intent返回Activity時當前activity無法關閉

Android intent返回Activity時當前activity無法關閉

我是剛入門的菜鳥，求各位大神幫忙看看，以下是我操作是的界面截圖和代碼，跪求幫！！！

 button1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                int a = Integer.parseInt(one.getText().toString());
                int b = Integer.parseInt(two.getText().toString());
                Intent intent = new Intent(MainActivity.this,OtherActivity.class);
                intent.putExtra("a", a);
                intent.putExtra("b", b);
                startActivity(intent);
                startActivityForResult(intent, REQUESTCODE);    //返回結果
            }
        });

 button2.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                Intent intent = new Intent(OtherActivity.this, MainActivity.class);
                int three = Integer.parseInt(editText.getText().toString());
                intent.putExtra("three", three);
                //通過Intent對象返回結果，setResult方法
                setResult(1,intent);
                finish();   //結束當前activity的生命周期。
            }
        });

 protected void onActivityResult(int arg0, int arg1, Intent arg2) {
        // TODO Auto-generated method stub
        super.onActivityResult(arg0, arg1, arg2);
        if (arg1 == 1) {
            if (arg0 == REQUESTCODE) {
                int thre = arg2.getIntExtra("three", 0);
                result.setText(String.valueOf(thre));
            }
        }
    }

最佳回答：

仔細看代碼：
startActivity(intent);
startActivityForResult(intent, REQUESTCODE); //返回結果
去掉第一行那個startActivity應該就可以了
