Custom View-a simple circular SS effect, view-circular Progress Let's take a look. We want to implement a custom View and draw an arc-shaped custom View in another circle. The idea is as follows: First, you must create a class ProgressView, inherit from the View class, and then override the two constructor methods. One is a parameter and the other is two parameters, because we want to use the custom contro

Various loading and circular progress effects, loading circular progress Effects Recently, the APP's progress loading effect needs to be modified to simulate the IOS color gradient effect. At the beginning, 12 images are rotated sequentially and placed in the animation-list to implement frame animation, after implementation, the effect is not very smooth. Later I thought of putting a loading image into the

Circular elements are widely used in interface design, from common circular icons to rounded heads or rounded contour shapes. A circle is a special shape that can be quickly noticed by us in many geometric shapes. As such, there are a few caveats when designing an interface with a round element. 　One, round Head Looking around, the rounded avatar has occupied our mobile phone. Take a look at these example

First, the circulation structure A circular statement can be used to satisfy a cyclic condition repeated execution of a piece of code, the repeated execution of the code is called the Loop body statement, when the recurrence of the loop body, the need to be in the appropriate time to change the cyclic judgment condition to false, thus ending the loop, otherwise the loop will continue to form a dead loop.
