为什么不的EditText使用？ – user370305

当播放器单击答案按钮时，应该打开虚拟键盘，并且每个按键都必须写入textView，而不是EditText。 – beetle

只需使用EditText与android：cursorVisible =“false”，它将看起来像一个TextView ..简单:-) – user370305

答

KeyEvent对象应该为您提供所需的功能。

答

如果您确实想捕获击键，则可以使用OnKeyListener。请点击此链接 Here

我试图做到这一点，但此代码不起作用。 answerButton.setOnKeyListener（新OnKeyListener（）{ @覆盖公共布尔安其（视图V，INT的keyCode，KeyEvent的事件） { 信[5] .setVisibility（View.INVISIBLE）; 如果（键代码== KeyEvent.KEYCODE_A） { letter [1] .setText（“A”）; } return false; } }）; – beetle

我忘了expalin它，我有一个名为addCourseText的EditText，当单击enter键或d-pad时，它将调用addCourseFromTextBox函数。 – LuminiousAndroid

嘿按照此下面的代码： -

addCourseText = (EditText) findViewById(R.id.clEtAddCourse); 
addCourseText.setOnKeyListener(new OnKeyListener() 
{ 
    public boolean onKey(View v, int keyCode, KeyEvent event) 
    { 
     if (event.getAction() == KeyEvent.ACTION_DOWN) 
     { 
      switch (keyCode) 
      { 
       case KeyEvent.KEYCODE_DPAD_CENTER: 
       case KeyEvent.KEYCODE_ENTER: 
        addCourseFromTextBox(); 
        return true; 
       default: 
        break; 
      } 
     } 
     return false; 
    } 
});
