When we don't know how it is distributed, we always feel confused, therefore, it is necessary to understand its overall distribution process, so it is necessary to keep a

The example of this article describes the Android touch screen test code, can realize the touch screen of the Click, move, leave and other events, for Android beginners have a good reference value. The specific function code is as follows: Package com.test; Import android.app.Activity; Import Android.os.Bundle; I

(Event. Getpointerid (i), action_id,Event. GetX (i),Event. GetY (i));}This action value is variable when Android is multi-touch. But it's very regular, (I don't know what Android is, it's not clear why), only one click is action = 0;When there are two click points will become 261 (256 + 5 + 0), when there are 3 points of Click will become 517 (512 + 5 + 0) and s

Android Touch-screen event deliveryA: Preface before due to do launcher part, involves a lot of interactive parts, because the project in the past a long time, and recently in doing gts,cts test and modification, many are not familiar with or even forget, combined with other people's article experience (I found that some places and others discrepancies, But self-test verification), coupled with their own te

intended to assign to the programmer, suddenly he did not want to pass, on the way to intercept down.And in our Android Touch event delivery mechanism is similar to this, the idea is almost, there is a saying, design comes from life. There are three main ways to deal with touch events:Dispatch Event Public boolean dispatchtouchevent (motionevent ev)//Intercept E

The existence of a simulator plays a role in it, but do not trust it in everything. Unless you are an android pure upper-layer application developer or enthusiast, I suggest you discard the simulator. Its idealized guidance makes us a lot of trouble. Of course, this is also a good thing. At the very least, I was more interested in fi
