The event types in android include button events and screen Touch events. Touch events are the basic events of screen Touch events, so it is necessary to have a deep understanding of them.A simple screen Touch action triggers a series of Touch events: ACTION_DOWN-> ACTION_MOVE...-> ACTION_MOVE-> ACTION_UPWhen the screen contains a ViewGroup and the ViewGroup contains a sub-view, how does the

Android event bus and android Bus In Android, communication between Activity, Service, and Fragment is troublesome. The main methods are as follows: (1) When broadcast is used, the sender sends a broadcast, and the receiver receives the broadcast for processing; (2) Use Handler and Message. For example, after the downl

example, move), the event will be turned into a cancel event and passed to the child view that previously handled the gesture (gesture). The Ontouchevent method for ViewGroup is no longer passed (whether it is an intercepted move or a system-generated cancel). Only the events that come again will be passed to the ViewGroup ontouchevent method. From now on, you can go further: For example, ove

Android Touch event distribution mechanism: androidtouch Preface The delivery of touch events in Android is worth studying. I have never seen you introduce a ListView slide function, so that ListView will not follow your finger's call to scroll. I also don't know why the Button has set onClick and onTouch. Who will first respond; maybe you will ask what is the di

First, the bug appeared, Need to "kill" it is a scary bug, but as long as you understand, Android bug is very good solution, because Android provides the log mechanism, the specific underlying code, in the future to analyze, as long as you will see the bug, Application development in Android is also very simple. Let's
