Touch分发 demo打印

标签（空格分隔）：点击事件

1、测试布局

父view：

button ：测试点击事件
自定义button：打印 dispatchTouchEvent 和onTouchEvent
edittext：测试是否可以获取焦点
yellowRela：是否和button的效果一样
maskRela：最外面的子view 如何影响底下的view
buttonRela 两个button的父View
clickRela 在最底部监听事件是否能到达

Part 1.先看mask和yellow之间的关系

1、mask不做任何处理：

点击空白

12-02 14:21:11.356 32004-32004/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)

12-02 14:21:11.356 32004-32004/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)

点击mask

12-02 14:24:31.996 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:24:31.996 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)

12-02 14:24:32.006 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask onTouchEvent
12-02 14:24:32.006 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)

事件的回传

点击yellow

12-02 14:25:04.196 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:25:04.196 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)

12-02 14:25:04.196 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow dispatchTouchEvent拦截了
12-02 14:25:04.206 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow onInterceptTouchEvent
12-02 14:25:04.206 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow onTouchEvent
12-02 14:25:04.206 6263-6263/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)

yellow dispatchTouchEvent true

12-02 14:32:55.846 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:32:55.846 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 14:32:55.846 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask dispatchTouchEvent拦截了
12-02 14:32:55.846 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask onInterceptTouchEvent
12-02 14:32:55.846 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask onTouchEvent
12-02 14:32:55.846 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow dispatchTouchEvent拦截了
12-02 14:32:55.896 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:32:55.896 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 14:32:55.906 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow dispatchTouchEvent拦截了

这时不会走yellow其他方法了 up和down

yellow dispathcTouchEvent false

12-02 14:34:20.396 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:34:20.396 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 14:34:20.396 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask dispatchTouchEvent拦截了
12-02 14:34:20.396 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask onInterceptTouchEvent
12-02 14:34:20.406 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask onTouchEvent
12-02 14:34:20.406 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow dispatchTouchEvent拦截了
12-02 14:34:20.406 13275-13275/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)

这时不会走yellow其他方法了只有down

2、mask dispatchTouchEvent 处理

1 、 true 任何有mask的区域：

12-02 14:28:44.366 8422-8422/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:28:44.366 8422-8422/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 14:28:44.366 8422-8422/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask dispatchTouchEvent拦截了
12-02 14:28:44.466 8422-8422/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:28:44.466 8422-8422/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 14:28:44.466 8422-8422/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask dispatchTouchEvent拦截了

edittext 不会再弹出键盘

2、false

false只有mask的部分

12-02 14:45:31.996 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:45:31.996 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 14:45:31.996 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask dispatchTouchEvent拦截了
12-02 14:45:31.996 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)

和yellow是一致的直接父类ontouch

false yellow部分

12-02 14:46:57.376 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 14:46:57.376 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 14:46:57.376 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask dispatchTouchEvent拦截了
12-02 14:46:57.376 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow dispatchTouchEvent拦截了
12-02 14:46:57.376 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow onInterceptTouchEvent
12-02 14:46:57.376 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow onTouchEvent
12-02 14:46:57.376 23041-23041/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)

上下次序是不会变的 yellow肯定会晚于mask执行

Part 2.ButtonRela和ClickRela 之间的关系

（相当于对yellow加了子类,这里mask都为dispatchTouchEvent false）

点击buttonRela以外的部分

mask外

12-02 15:11:55.696 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 15:11:55.696 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 15:11:55.696 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)
12-02 15:11:55.776 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: bottom click

mask上

12-02 15:12:43.856 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 15:12:43.856 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 15:12:43.856 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask dispatchTouchEvent拦截了
12-02 15:12:43.856 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)
12-02 15:12:43.926 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: bottom click

yellow上

12-02 15:13:39.896 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 15:13:39.896 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 15:13:39.896 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: mask dispatchTouchEvent拦截了
12-02 15:13:39.896 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow dispatchTouchEvent拦截了
12-02 15:13:39.896 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow onInterceptTouchEvent
12-02 15:13:39.896 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: yellow onTouchEvent
12-02 15:13:39.896 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onTouchEvent(ev)
12-02 15:13:39.986 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: bottom click

Clickrela 都能接收到监听

点击普通Button

12-02 15:15:41.566 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.dispatchTouchEvent(ev)
12-02 15:15:41.566 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)

12-02 15:15:41.636 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: 父view：super.onInterceptTouchEvent(ev)
12-02 15:15:41.646 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: ButtonRela dispatchTouchEvent拦截了
12-02 15:15:41.646 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: ButtonRela onInterceptTouchEvent
12-02 15:15:41.646 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: button点击了

button 消耗掉了事件不会出现父view ouTouch的回传了

点击greenbutton （不做任何处理）

12-02 15:19:09.456 14507-14507/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: GreenButton点击了

手势的up和down 所以走了两遍

点击greenbutton （dispatchTouchEvent false）

经过上面的总结猜测返回false则穿透

事件的up和down 走了两遍 touch事件不会执行，自己监听不到，底部也监听不到（事件去哪了？）(这时up时mask也不会再执行了因为返回了false)

点击greenbutton （onTouchEvent true）

12-02 15:36:22.776 31200-31200/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: GreenButton onTouchEvent

事件的up和down onClick 不会执行了顺序同上述的viewgroup是一样的底部也监听不到

点击greenbutton （onTouchEvent false）

12-02 15:38:33.436 31200-31200/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: bottom click

只有down没有 up onclick不会执行了自己监听不到底部可以监听到了

Part 3.ButtonRela和Button之间的关系

测试父级dispatch 对子级的影响

ButtonRela dispatche返回false

12-06 19:46:10.334 20268-20268/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: bottom click

直接拦截了不会传递给子类了和maskRela的是一样的

ButtonRela dispatche返回

12-06 19:48:41.794 29453-29453/com.linewow.xhyy.dispatcherdemo2 E/MainActivity: ButtonRela dispatchTouchEvent拦截了

同样不会传递给子类重复的次数取决于 motionevent的次数

所以dispatche返回true表示事件被当前视图消耗掉了所以不会继续分发了连续的打印则是事件的不断进入

2、总结

dispatchTouchEvent决定了兄弟直接的拦截
onInterceptTouchEvent 决定了父子之间的拦截
