Android:从软键盘中删除 Enter 键

问题描述

在我的登录表单中，当用户单击 EditText 并按下回车键时，这会插入一个新行，因此会增加 EditText 的大小.下一刻，它返回到之前的位置并在密码字段(即下一个字段)中打印一个点.

In my login form when user clicks on an EditText and presses the enter key, this inserts a new line, therefore increasing the EditText's size. Next moment, it returns to its previous place and prints a dot in the password field (which is the next field).

我想从软键盘中删除这个回车键.有可能吗?

I want to remove this enter key from the softkeyboard. Is it possible?

推荐答案

恐怕你做不到.但有一件事是你可以像这样处理软键盘按键事件，

I am afraid you can't do this. But one thing is you can handle the softkeyboard keyevents like this,

edittext.setOnKeyListener(new OnKeyListener() {

        public boolean onKey(View v, int keyCode, KeyEvent event) {


                if (event.getAction() == KeyEvent.ACTION_DOWN
                        && event.getKeyCode() ==       KeyEvent.KEYCODE_ENTER) {
                    Log.i("event", "captured");

                    return false;
                } 
                else if(event.getAction() == KeyEvent.ACTION_DOWN
                        && event.getKeyCode() == KeyEvent.KEYCODE_BACK){
                    Log.i("Back event Trigered","Back event");

                }

            }

            }
            return false;
        }
    });

除此之外，您必须注意，提供属性 android:singleLine=true 将使您的编辑文本在按下软键盘 ENTER 时变大

Apart from this, you have to note that providing the attribute android:singleLine=true will make your edittext from growing in size when the soft keyborad ENTER is pressed
