This process is just speculation. I didn't analyze the source code in depth, but I typed a log and the result was that a series of dispatchTouchEvent () did return true. In other words, ViewGroup1 and ViewGroup2 did not have a consumption event, but dispatchTouchEvent () returned true, so an online saying: DispatchTouchEvent () returned true is a consumption event. This statement may not be completely accurate, but we still need to go to the source code to find the answer. We will not analyze it here, but only explain one problem: don't rewrite dispatchTouchEvent () easily. Even if overridden, try to ensure that the super method is called and the return value is consistent with the super result. In fact, the source code already provides two interfaces to indirectly rewrite it, namely onInterceptTouchEvent () and onTouchEvent (), which can be known from the source code that they are eventually called by dispatchTouchEvent (). Moreover, it is no problem to use the return value of onTouchEvent () to describe whether to consume the event (View that does not consume the event cannot call onTouchEvent () at all).State machines also have a wide range of uses in game development, especially the logic writing of game AI. The main characters in the game have various states such as walking, attacking, defending, falling and jumping. These states are both interrelated and constrained. For example, if attacked during walking, it will switch from walking state to falling state. In the state of falling, it can neither attack nor defend. Similarly, you cannot switch to the defensive state during the jump, but you can attack. This kind of scenario is very suitable to be described by state machine.
