I thought this thing was the same as before, Is to rush up and bite people, So we're just shooting with guns, When the distance is close, throw it with a grenade. At the most dangerous time, even mines are thrown out, At that time, the 'round head' anti-infantry mine (still referring to Type 72 anti-infantry mine) had a 'bolt' (i.e. Safety ring) under it. Just pull it out, Throw it out like a grenade, But more powerful than a grenade, As soon as a large area is blown up, But because it is heavier, More than three grenades, Therefore, those with weak throwing ability generally dare not use it like this. Because I'm afraid I can't throw it out of the safe range and blow it up to myself, But fortunately, whatever it is, As long as you want to attack, It must be an attack on the ground, We have a great advantage from a high position. Throwing explosives from high to low can increase the throwing distance, Even if you can't throw it far away, After landing, you can also roll down a little further distance. Therefore, some comrades who throw grenades not far away can also throw mines away from a safe distance to strike the enemy. Then there is the explosive cartridge, The vast majority of people can't throw out three pieces of explosive cartridges in one go like a company commander. And it is too wasteful to throw them all like that, So he threw the explosive cartridges out one by one, When the "big grenade" is used, The reason why I dare to do this and make such "rich" moves is because there are not many others in our positions, that is, grenades, mines and explosive cartridges are plenty of explosives, and many to "tube enough", thanks to these, otherwise in the period of time without artillery support, the Vietnamese army's offensive forces increased several times, and the guns in hand alone could not hold up completely.本片为纪念徐向前元帅百年诞辰而作,同时寄托我们在新的世纪对共和国开国元勋的缅怀之情。徐帅作为山西人,也是北方唯一的元帅,一生充满传奇色彩。作为红四方面军的总指挥,他参与了人民军队的缔造,辉煌的战绩使他杰出的军事才能永载史册。荣辱不惊、忠诚执著、大智大勇、坚韧不拔,徐帅闪耀着理想之光的奋斗历程,构成了一代元戎灿烂群星中一道独特的风景。本片选取解放战争中的山西战场作为载体,通过运城、临汾、晋中和太原战……Know the principle + can change the model details man: read the paper, read the paper, read the paper! Read source code read source code read source code! The source code reading here is not limited to reading the source code of one framework. You can look at other excellent frameworks. For the implementation mechanism of the same layer and the same function, you can think more, summarize more and write more. After a long time, there will definitely be gains. The purpose of reading the paper is to directly obtain the original author's thoughts, avoiding obtaining second-hand thoughts from blog interpretation of the paper. After all, everyone's understanding is different, and it is not necessarily right. Read it first, then look at other understandings, and discuss with Daniel more, thus broadening the thinking.Countries still keep their cards, so no one can know for sure which countries are capable of launching the largest attacks.

By default, Activity/ViewGroup/View does not intercept non-consumption events. It is easy to see from the log that the down event has gone through the following process, the following is the distribution process, and the following is the consumption process. If no one intercepts the distribution, the event will be passed down to the child view. If the child view does not consume the event, it will be passed to the parent view for consumption, i.e. The onTouchEvent of the parent view will be called back in turn.
