Cannot Find Any File!!"); return; } fputs(str,f); fclose(f); ch = commonestLetter("input.txt"); }，这是我的代码

您可以使用以下功能检测它：

<TextView
android:id="@+id/tv_dialog"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_centerInParent="true"
android:background="@android:color/darker_gray"
android:gravity="center"
android:textColor="#ffffffff"
android:textSize="30dp"
android:visibility="gone"/>

<com.myspace.maoyannew.view.MyLetterView
    android:id="@+id/my_letterview"
    android:layout_width="25dp"
    android:layout_height="match_parent"
    android:layout_alignParentRight="true"
    android:layout_marginRight="2dp"
    android:layout_marginTop="7dp">

</com.myspace.myspace.view.MyLetterView>

document.addEventListener("keydown", function (event) { event.stopPropagation(); event.preventDefault(); if(event.ctrlKey && event.keyCode == 81) { console.log("CTRL + Q was pressed!"); } else { console.log("Something else was pressed."); } });和stopPropagation()调用会阻止浏览器的默认行为发生。

如果您想检测其他密钥，此页面非常有用：http://asquare.net/javascript/tests/KeyCode.html
