为了指代方便，下面将MyLinearLayout简称为L，将MyTextView简称为T，L.onInterceptTouchEvent=true 表示的含义为MyLinearLayout中的onInterceptTouchEvent方法返回值为true，通过程序运行时输出的Log来说明调用时序。
第1种情况 L.onInterceptTouchEvent=false&& L.onTouchEvent=true &&T.onTouchEvent=true 输出下面的Log：
D/MyLinearLayout(11865): dispatchTouchEvent action:ACTION_DOWN
D/MyLinearLayout(11865): onInterceptTouchEvent action:ACTION_DOWN
D/MyTextView(11865): dispatchTouchEvent action:ACTION_DOWN
D/MyTextView(11865): ---onTouchEvent action:ACTION_DOWN
D/MyLinearLayout(11865): dispatchTouchEvent action:ACTION_MOVE
D/MyLinearLayout(11865): onInterceptTouchEvent action:ACTION_MOVE
D/MyTextView(11865): dispatchTouchEvent action:ACTION_MOVE
D/MyTextView(11865): ---onTouchEvent action:ACTION_MOVE
...........省略其他的ACTION_MOVE事件Log
D/MyLinearLayout(11865): dispatchTouchEvent action:ACTION_UP
D/MyLinearLayout(11865): onInterceptTouchEvent action:ACTION_UP
D/MyTextView(11865): dispatchTouchEvent action:ACTION_UP
D/MyTextView(11865): ---onTouchEvent action:ACTION_UP
结论：TouchEvent完全由TextView处理。
第2种情况?<wbr><span class="Apple-converted-space">?</span>L.onInterceptTouchEvent=false&& L.onTouchEvent=true &&T.onTouchEvent=false 输出下面的Log：<br>D/MyLinearLayout(13101): dispatchTouchEvent action:ACTION_DOWN<br>D/MyLinearLayout(13101): onInterceptTouchEvent action:ACTION_DOWN<br>D/MyTextView(13101): dispatchTouchEvent action:ACTION_DOWN<br>D/MyTextView(13101): ---onTouchEvent action:ACTION_DOWN<br>D/MyLinearLayout(13101): ---onTouchEvent action:ACTION_DOWN<br>D/MyLinearLayout(13101): dispatchTouchEvent action:ACTION_MOVE<br>D/MyLinearLayout(13101): ---onTouchEvent action:ACTION_MOVE<br>...........省略其他的ACTION_MOVE事件Log<br>D/MyLinearLayout(13101): dispatchTouchEvent action:ACTION_UP<br>D/MyLinearLayout(13101): ---onTouchEvent action:ACTION_UP<br>结论：TextView只处理了ACTION_DOWN事件，LinearLayout处理了所有的TouchEvent。<br>第3种情况?<wbr><span class="Apple-converted-space">?</span>L.onInterceptTouchEvent=true&& L.onTouchEvent=true 输出下面的Log：<br>D/MyLinearLayout(13334): dispatchTouchEvent action:ACTION_DOWN<br>D/MyLinearLayout(13334): onInterceptTouchEvent action:ACTION_DOWN<br>D/MyLinearLayout(13334): ---onTouchEvent action:ACTION_DOWN<br>D/MyLinearLayout(13334): dispatchTouchEvent action:ACTION_MOVE<br>D/MyLinearLayout(13334): ---onTouchEvent action:ACTION_MOVE<br>...........省略其他的ACTION_MOVE事件Log<br>D/MyLinearLayout(13334): dispatchTouchEvent action:ACTION_UP<br>D/MyLinearLayout(13334): ---onTouchEvent action:ACTION_UP<br>结论：LinearLayout处理了所有的TouchEvent。<br>第4种情况?<wbr><span class="Apple-converted-space">?</span>L.onInterceptTouchEvent=true&& L.onTouchEvent=false 输出下面的Log：<br>D/MyLinearLayout(13452): dispatchTouchEvent action:ACTION_DOWN<br>D/MyLinearLayout(13452): onInterceptTouchEvent action:ACTION_DOWN<br>D/MyLinearLayout(13452): ---onTouchEvent action:ACTION_DOWN<br>结论：LinearLayout只处理了ACTION_DOWN事件，那么其他的TouchEvent被谁处理了呢？答案是LinearLayout最外层的Activity处理了TouchEvent。</wbr></wbr></wbr>
