我尝试使用onFocusChangeListener制作三个可以点击的EditTexts，但有时我会得到这个：

我使用此代码：

buttonEditText.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus){
                v.clearFocus();
                Intent i = new Intent(getApplicationContext(), LeuteEinladen.class);
                startActivityForResult(i, Details);
            });
            }
        }
    });

我开始的活动完全正常，所以这不是理由。当我尝试使用普通Button和onClickListener时，没有问题。 我也尝试使用EditText上的onClickListener，但这也不起作用。 现在我解决了，问题总是出现，当我启动Activity（点击EditText）关闭它，所以我回到使用EditTexts的Acitivity并想要点击另一个带有onFocusChangeListener的EditText 为了避免这种情况，我该怎么做？在此先感谢：）

答案 0 :(得分：0)

当您第一次启动时，您的活动会自动调用onfocuschange方法，因为此时它会收到onfocus，您的logcat显示stackoverflow错误，这意味着您的活动没有其他控件来接收onfocus，因此它表示stackoverflow
