View事件的分发机制请参考以上流程图的截图，现在进行以下文字说明。
1、dispatchTouchEvent(Activity) -> dispatchTouchEvent (FatcherViewGroup) -> onInterceptTouchEvent(FatcherViewGroup) -> dispatchTouchEvent ( SonViewGroup) -> onInterceptTouchEvent(SonViewGroup) ..........
以上是从Activity开始先进入dispatchTouchEvent如果返回true则后续不比再往下分发，如果dispatchTouchEvent返回false则进入onInterceptTouchEvent，如果为true本View拦截所有事件，不必继续往下继续分发；如果该值为false则继续往下分发。其中Activity中没有onInterceptTouchEvent所以不执行。
2、如果dispatchTouchEvent为true或者onInterceptTouchEvent为true,则本View处理所有的分发事件，执行顺序如下：
以FatcherViewGroup的onInterceptTouchEvent为例：
dispatchTouchEvent(Activity，Action_Down) -> dispatchTouchEvent (FatcherViewGroup，Action_Down) -> onInterceptTouchEvent(FatcherViewGroup，Action_Down) -> onTouchEvent(FatcherViewGroup，Action_Down)-> dispatchTouchEvent(Activity，Action_Move) -> dispatchTouchEvent (FatcherViewGroup，Action_Move) -> onInterceptTouchEvent(FatcherViewGroup，Action_Move) -> onTouchEvent(FatcherViewGroup，Action_Move)-> ...... .... -> dispatchTouchEvent(Activity，Action_Up) -> dispatchTouchEvent (FatcherViewGroup，Action_Up) -> onInterceptTouchEvent(FatcherViewGroup，Action_Up) -> onTouchEvent(FatcherViewGroup，Action_Up)
如果FatcherViewGroup中的 onTouchEvent返回为false并且FatcherViewGroup设置了OnClickListener(即是有了点击事件的监听)则在执行FatcherViewGroup的Action_Up之后OnTouchEvent后面追加如下：onTouchEvent(FatcherViewGroup，Action_Up) -> performClick (FatcherViewGroup，Action_Up)-> Click (FatcherViewGroup，Action_Up)。当然执行performClick返回为false才会执行click。
以上已经完整的对View的分发事件进行了说明，现在写个DEMO进行测试
DEMO的结构图如下所示：
以下是代码：
a、touch_event_main.xml
<?xml version="1.0" encoding="utf-8"?>
<com.example.wangqiubo.myapplication.vieweventdispatch.FatherTouchEventView xmlns:android="http://schemas.android.com/apk/res/android"

</com.example.wangqiubo.myapplication.vieweventdispatch.SonTouchEventView>
</com.example.wangqiubo.myapplication.vieweventdispatch.FatherTouchEventView>
b、ViewEventActivity.java
package com.example.wangqiubo.myapplication.vieweventdispatch;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import com.example.wangqiubo.myapplication
.R;
public class ViewEventActivity extends Activity implements View.OnClickListener{
FatherTouchEventView fatherTouchEventView = null;
SonTouchEventView sonTouchEventView = null;
@Override
public void onCreate(Bundle bundle){
super.onCreate(bundle);
setContentView(R.layout.touch_event_main);
fatherTouchEventView = (FatherTouchEventView)findViewById(R.id.father_event);
sonTouchEventView = (SonTouchEventView)findViewById(R.id.son_touchevent);
fatherTouchEventView.setOnClickListener(this);
sonTouchEventView.setOnClickListener(this);
}
@Override
public boolean dispatchTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "Activity_dispatch_" + MotinEventUtil.getTouchEventName(event));
return super.dispatchTouchEvent(event);
}
@Override
public boolean onTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "Activity_touchEvent_" + MotinEventUtil.getTouchEventName(event));
return super.onTouchEvent(event);
}
@Override
public void onClick(View v) {
Log.d("ViewMotinEvent: ", "Activity_onClick");
if(v.getId() == R.id.father_event){
Log.d("ViewMotinEvent: ", "Activity_Father_onClickListenler");
}else if (v.getId() == R.id.son_touchevent){
Log.d("ViewMotinEvent: ", "Activity_Son_onClickListenler");
}
}
}
c、FatherTouchEventView.java。
package com.example.wangqiubo.myapplication.vieweventdispatch;
import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.widget.LinearLayout;
public class FatherTouchEventView extends LinearLayout implements View.OnClickListener{
public FatherTouchEventView(Context context) {
super(context);
}
public FatherTouchEventView(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public boolean dispatchTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "father_dispatch_" + MotinEventUtil.getTouchEventName(event));
// return false;
// return true;
return super.dispatchTouchEvent(event);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "father_intercept_" + MotinEventUtil.getTouchEventName(event));
// return true;
// return false;
return super.onInterceptTouchEvent(event);
}
@Override
public boolean onTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "father_touch_" + MotinEventUtil.getTouchEventName(event));
// return false;
return super.onTouchEvent(event);
}
@Override
public boolean performClick() {
Log.d("ViewMotinEvent: ", "father_performClick");
return super.performClick();
// return true;//super.performClick();
}
@Override
public void onClick(View v) {
Log.d("ViewMotinEvent: ", "Father_onClick");
}
}
d、SonTouchEventView.java。
package com.example.wangqiubo.myapplication.vieweventdispatch;
import android.content.Context;
import android.support.annotation.Nullable;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.widget.LinearLayout;
public class SonTouchEventView extends LinearLayout implements View.OnClickListener {
public SonTouchEventView(Context context) {
super(context);
}
public SonTouchEventView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
}
public SonTouchEventView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
public boolean dispatchTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "son_dispatch_" + MotinEventUtil.getTouchEventName(event));
// return true;
return super.dispatchTouchEvent(event);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "son_intercept_" + MotinEventUtil.getTouchEventName(event));
// return true;
return super.onInterceptTouchEvent(event);
}
@Override
public boolean onTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "son_touch_" + MotinEventUtil.getTouchEventName(event));
return super.onTouchEvent(event);
}
@Override
public boolean performClick() {
Log.d("ViewMotinEvent: ", "son_performClick_");
return super.performClick();
}
@Override
public void onClick(View v) {
Log.d("ViewMotinEvent: ", "Son_onClick");
}
}
e、Son2SonTouchEventView.java。
package com.example.wangqiubo.myapplication.vieweventdispatch;
import android.content.Context;
import android.support.annotation.Nullable;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.widget.LinearLayout;
public class Son2SonTouchEventView extends LinearLayout implements View.OnClickListener {
public Son2SonTouchEventView(Context context) {
super(context);
}
public Son2SonTouchEventView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
}
public Son2SonTouchEventView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
public boolean dispatchTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "son2son_dispatch_" + MotinEventUtil.getTouchEventName(event));
// return true;
return super.dispatchTouchEvent(event);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "son2son_intercept_" + MotinEventUtil.getTouchEventName(event));
return super.onInterceptTouchEvent(event);
}
@Override
public boolean onTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "son2son_touch_" + MotinEventUtil.getTouchEventName(event));
return super.onTouchEvent(event);
}
@Override
public boolean performClick() {
Log.d("ViewMotinEvent: ", "son2son_performClick_");
// return true;
return super.performClick();
}
@Override
public void onClick(View v) {
Log.d("ViewMotinEvent: ", "Son2Son_onClick");
}
}
请查看touch_event_main.xml，知道Son2SonTouchEventView 是 SonTouchEventView子节点，而SonTouchEventView是FatherTouchEventView子节点。
1、我们现在修改SonTouchEventView中的dispatchTouchEvent代码，修改如下：
@Override
public boolean dispatchTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "son_dispatch_" + MotinEventUtil.getTouchEventName(event));
return true;
// return super.dispatchTouchEvent(event);
}
即是dispatchTouchEvent返回true拦截事件，打印出的日志如下：

05-24 02:27:30.190 2495-2495/com.example.wangqiubo.myapplication D/ViewMotinEvent:: son_dispatch_action_up
因为Son2SonTouchEventView的dispatchTouchEvent拦截事件，所以终点在该VIEW的dispatchTouchEvent，后续的事件及其子节点的分发不再执行。
需要注意，每次的事件分发都是从顶级结点开始也就是Activity开始分发，分发出去，后续子View来决定是否拦截(是否拦截根据业务本身来决定)。
2、如果SonTouchEventView中的onInterceptTouchEvent代码，修改如下：
@Override
public boolean onInterceptTouchEvent(MotionEvent event){
Log.d("ViewMotinEvent: ", "son_intercept_" + MotinEventUtil.getTouchEventName(event));
return true;
// return super.onInterceptTouchEvent(event);
}
即是onInterceptTouchEvent返回true拦截事件，打印出的日志如下：

05-24 02:39:55.665 15550-15550/com.example.wangqiubo.myapplication D/ViewMotinEvent:: Activity_Son_onClickListenler
Son2SonTouchEventView的onInterceptTouchEvent拦截事件，则需要执行Son2SonTouchEventView中的onTouchEvent方法，进过无数个move，当执行Aciton_Up之后，因为onTouchEvent的返回值为false则事件需要继续传递，因为Son2SonTouchEventView设置了点击事件的监听，因此首选执行到performClick，因为performClick也返回为false,则继续往下执行进入ViewEventActivity的onClick，执行ViewEventActivity中设置的onClickListenler。(注意并没有执行Son2SonTouchEventView的click是因为click是设置的Activity，Activity继承了onClickListenler,本身performClick内部代码中会执行click)。
3、如果SonTouchEventView的代码不进行修改，按照以上文件进行执行结果会怎样呢？以下是输出的日志。

05-24 02:51:23.009 25477-25477/com.example.wangqiubo.myapplication D/ViewMotinEvent:: Activity_Son_onClickListenler
本输出日志有没注意到一个问题，在输出son2son_touch_action_domn之后，为什么之后没有执行Son2son_touch_action_move 和 Son2son_touch_action_up，而是执行的他的父亲结点
son_touch_action_move和son_touch_action_up，然后执行的其父亲结点的son_performClick。
要解决这问题，不妨，我们修改ViewEventActivity的代码如下：
注释掉这行代码 ：//sonTouchEventView.setOnClickListener(this);
输入日志如下：

05-24 03:01:08.388 549-549/com.example.wangqiubo.myapplication D/ViewMotinEvent:: Activity_Father_onClickListenler
通过以上日志，我们发现，这次并没有执行Son2son_touch_action_move 和 Son2son_touch_action_up ，并且没有执行其直接父亲的son_touch_action_move和son_touch_action_up，而是执行了其上上层父亲的的father_touch_action_move 和 father_touch_action_up及其 father_performClick
综合以上2个输入日志，得出的结论就是因为Son2SonTouchEventView没有设置Click的监听，并且其onTouchEvent返回为false，onTouchEvent 返回false则往上传一层，让其父亲处理，当其直接父亲SonTouchEventView设置了click事件监听时，自然而然进入了SonTouchEventView的performClick,执行完毕后回到了其click事件(Activity中)中，当SonTouchEventView没有设置click事件监听时，则事件继续往上一层传递，则传给了他的父亲FatherTouchEventView。
因此后续事件均由设置了click监听的View执行。因为SonTouchEventView 和 FatherTouchEventView 设置的OnClickListener是 ViewEventActivity，因此相对于performClick不处理事件的话，后续执行的是设置的OnClickListener，因此执行了Activity的click。
我们将代码修改为如下：
屏蔽掉ViewEventActivity中的以下两行：
//fatherTouchEventView.setOnClickListener(this);
//sonTouchEventView.setOnClickListener(this);
则事件分发，因为Son2SonTouchEventView、Son2SonTouchEventView、FatherTouchEventView都没有处理，则最后就交给了ViewEventActivity处理。
