当全为false时：down：layoutview1->layoutview2->mytextview->layoutview2->layoutview1

10-16 02:04:51.262: D/LayoutView1(393): onInterceptTouchEvent1 action:ACTION_DOWN
10-16 02:04:51.262: D/LayoutView1(393): onInterceptTouchEvent1 return:false
10-16 02:04:51.262: D/LayoutView2(393): onInterceptTouchEvent2 action:ACTION_DOWN
10-16 02:04:51.262: D/LayoutView2(393): onInterceptTouchEvent2 return:false
10-16 02:04:51.262: D/MyTextView(393): onTouchEvent_TextView action:ACTION_DOWN
10-16 02:04:51.262: D/MyTextView(393): onTouchEvent_TextView return:false
10-16 02:04:51.262: D/LayoutView2(393): onTouchEvent2 action:ACTION_DOWN
10-16 02:04:51.262: D/LayoutView2(393): onTouchEvent2 return:false
10-16 02:04:51.262: D/LayoutView1(393): onTouchEvent1 action:ACTION_DOWN
10-16 02:04:51.262: D/LayoutView1(393): onTouchEvent1 return:false

当mytextview的ontouchevent返回true时，其余的全为FALSE：

down-move-up：顺序layoutview1->layoutview2->mytextview

10-16 02:14:27.522: D/LayoutView1(427): onInterceptTouchEvent1 action:ACTION_DOWN
10-16 02:14:27.522: D/LayoutView1(427): onInterceptTouchEvent1 return:false
10-16 02:14:27.522: D/LayoutView2(427): onInterceptTouchEvent2 action:ACTION_DOWN
10-16 02:14:27.522: D/LayoutView2(427): onInterceptTouchEvent2 return:false
10-16 02:14:27.522: D/MyTextView(427): onTouchEvent_TextView action:ACTION_DOWN
10-16 02:14:27.522: D/MyTextView(427): onTouchEvent_TextView return:true

10-16 02:21:57.672: D/LayoutView1(427): onInterceptTouchEvent1 action:ACTION_MOVE

10-16 02:21:57.672: D/LayoutView1(427): onInterceptTouchEvent1 return:false
10-16 02:21:57.672: D/LayoutView2(427): onInterceptTouchEvent2 action:ACTION_MOVE
10-16 02:21:57.672: D/LayoutView2(427): onInterceptTouchEvent2 return:false
10-16 02:21:57.672: D/MyTextView(427): onTouchEvent_TextView action:ACTION_MOVE
10-16 02:21:57.672: D/MyTextView(427): onTouchEvent_TextView return:true
10-16 02:14:27.585: D/LayoutView1(427): onInterceptTouchEvent1 action:ACTION_UP
10-16 02:14:27.585: D/LayoutView1(427): onInterceptTouchEvent1 return:false
10-16 02:14:27.585: D/LayoutView2(427): onInterceptTouchEvent2 action:ACTION_UP
10-16 02:14:27.585: D/LayoutView2(427): onInterceptTouchEvent2 return:false
10-16 02:14:27.585: D/MyTextView(427): onTouchEvent_TextView action:ACTION_UP
10-16 02:14:27.585: D/MyTextView(427): onTouchEvent_TextView return:true

3.LayoutView1，LayoutView2的onInterceptTouchEvent()处理事件返回false,MyTextView的onTouchEvent()处理事件返回false,LayoutView2的onTouchEvent()处理事件返回true

由于MyTextView在onTouchEvent()中return false，down事件被传递给其父view，即LayoutView2的onTouchEvent()方法处理，由于在LayoutView2的onTouchEvent()中return true，所以down事件传递并没有上传到LayoutView1。注意，后续的move和up事件均被传递给LayoutView2的onTouchEvent()处理，而没有传递给MyTextView。
