我对Enter中和roid中的关键有问题,我有一张折页,在我输入价值时,当我点击Enter时,我想作些什么。 我的问题是,我不得不两次发布Enter,以取得预期成果。

    editText1.setOnKeyListener(new OnKeyListener() {
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            // If the event is a key-down event on the "enter" button
            if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
                (keyCode == KeyEvent.KEYCODE_ENTER)) {

              // Perform action on key press
              mWebView.loadUrl(editText1.getText().toString());
              mWebView.requestFocus(); 
              return true;
            }
            return false;
        }
    });
最佳回答

我以前曾有过类似的问题。 您用实际电话对此事进行了测试,或只是在主人中尝试。 我不能记住我最初经历的具体内容,但我发现,这是由于 em晚造成的。 签字,并把它放在电话上,看是否会产生预期的效果。 然而,如果这没有给你解决,则要检查其他职位:
