问题描述

我有一点怀疑。我使用的是图像按钮（媒体播放器，例如播放图标）。我想知道哪些动作监听器，我应该使用，onClickListener或onTouchListener。这两个动作，当我应该使用。

I have a bit of doubt. I am using an image button (e.g. Play icon in media player). I want to know which action Listener I am supposed to use, onClickListener or onTouchListener. What is the difference between those two actions and when should I use either.

推荐答案

• onClickListener 时则使用一个单击事件的任何观点提出，例如说：单击事件按钮，ImageButton的。

• onClickListener is used whenever a click event for any view is raised, say for example: click event for Button, ImageButton.

  onTouchListener 每当你想实现触摸样的功能时，比方说，如果你想获得坐标的屏幕，在这里你接触完全。

  onTouchListener is used whenever you want to implement Touch kind of functionality, say for example if you want to get co-ordinates of screen where you touch exactly.

  只是检查这两个官方文档：<一href="http://developer.android.com/reference/android/view/View.OnClickListener.html">onClickListener和<一href="http://developer.android.com/reference/android/view/View.OnTouchListener.html">onTouchListener.

  Just check the official doc for both: onClickListener and onTouchListener.

  因此​​，从官方文档，定义都是：

  So from official doc, definition for both are:

  • onClickListner ：视图被点击时要调用回调接口定义
  • onTouchListener ：因为当一个触摸事件被调度到这一观点被调用的回调接口定义。回调将被调用的触摸事件给视图之前。
  • onClickListner: Interface definition for a callback to be invoked when a view is clicked.
  • onTouchListener: Interface definition for a callback to be invoked when a touch event is dispatched to this view. The callback will be invoked before the touch event is given to the view.
