如何听软键盘中的按键?

问题描述

我需要一个监听器来识别软键盘/屏幕键盘中的按键.

I need a listener to identify the keypress in the soft keyboard/on screen keyboard.

我尝试使用 addtextchangelistener textwatcher，但这个结果很好，但是当一些文本粘贴到其中时，它也会显示更改.

I tried with addtextchangelistener textwatcher but this one give the good result but it shows the change also when some text is pasted into it.

我只需要识别用户的按键.

I need to identify only the key press by the user.

有什么方法可以检测到按键.

推荐答案

看到这个 keyevent 并使用以下代码来识别用户按下了哪个键.

see this keyevent and use following code to identify which key is pressed by Users.

  @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) 
    {
         // Do Code here
    }
else if(keyCode == KeyEvent.KEYCODE_0) 
   {

   }
else if(keyCode == KeyEvent.KEYCODE_1) 
   {

   }
return super.onKeyDown(keyCode, event); }
