Android uses viewflipper to switch pictures

Today, let's briefly talk about Android gestures. At present, gestures are rarely used in apps on the market. Android provides two kinds of gestures: ①. Android provides gesture detection and provides corresponding listeners for gesture detection ②. Android allows developers to add gestures and provides corresponding APIs to recognize user gestures

In a previous blog, I talked about how to use viewpager to realize image sliding and address switching: Android uses viewpager to realize image sliding preview effect

However, viewpager has its own gesture recognition, which means that it will automatically recognize whether the gesture is sliding right or left. Today, I'll talk about how to use the viewflipper control to realize picture sliding switching. The code is very simple. I'll write the implementation code below.

activity_ mian.xml

Viewpager has its own animation for image switching, and viewflipper does not have its own animation for switching, so we can write the animation first, and now create a folder anim under the res folder

Then write the animation file in the anim folder

left_ in.xml

left_ out.xml

right_ in.xml

right_ out.xml

MainActivity.java

The above code can realize picture switching!
