Android View的事件传递《1》
触摸事件的传递流程是从deispatchTouchEvent开始的，如果是默认的返回值，事件会依次按嵌套层次从外层向内层传递，到达最内层的View时，就由它的onTouchEvent方法处理，该方法如果能够处理该事件，则返回true,如果处理不了，则返回false，这时事件会重新像外层(父容器)传递，并由外层View的onTouchEvent方法进行处理，以此类推。
如果事件再内层传递的过程中将事件处理函数返回ture，则会导致时间提前被消耗，view不会继续分发。
VIew控件的事件触发顺序是先执行onTouch方法，最后才执行onClick方法。
