What's the matter with Xiaomi 8 not responding to uniapp animation?

Recently, many users have encountered a problem when using uniapp, that is, on the Xiaomi 8 mobile phone, the animation effect cannot be displayed normally, and the expected animation effect does not appear. This is a relatively common problem. In this article, we will analyze the problem and provide some solutions.

First of all, we need to understand how animation effects are implemented in uniapp. The animation effect in uniapp is mainly realized through the CSS3 properties of H5. uniapp encapsulates these properties into some commonly used animation classes for the convenience of developers. For example, if we need to implement an animation that slides up from the bottom of the screen, we can use the following code:

.slide-up-enter-active {
  transition: all 0.3s ease-out;
  transform: translateY(100%);
}
.slide-up-leave-active {
  transition: all 0.3s ease-out;
  transform: translateY(-100%);
}
.slide-up-enter,
.slide-up-leave-to {
  transform: translateY(0);
}

There may be many reasons why the animation effect cannot be displayed normally on the Xiaomi Mi 8 mobile phone. Below we will start with the following Let’s analyze it from several aspects:

1. Xiaomi 8’s browser compatibility issues

First of all, we need to understand that not all browsers can fully support the CSS3 properties of H5 . The support of different browsers may vary, and the browser version of Xiaomi 8, especially the browser that comes with the MIUI system, may have compatibility issues, which results in the animation effect not being displayed properly on Xiaomi 8 mobile phones. .

Solution:

For this problem, we can solve it in the following ways:

• It is recommended to use the Chrome browser for debugging on Xiaomi 8 mobile phone , because the Chrome browser has better compatibility;
• For the browser that comes with Xiaomi 8, we can manually add the browser prefix to the style to be compatible with different versions of different browsers. For example, we can modify the above code to:

.slide-up-enter-active {
  -webkit-transition: all 0.3s ease-out;
  -moz-transition: all 0.3s ease-out;
  -o-transition: all 0.3s ease-out;
  transition: all 0.3s ease-out;
  -webkit-transform: translateY(100%);
  -moz-transform: translateY(100%);
  -o-transform: translateY(100%);
  transform: translateY(100%);
}
.slide-up-leave-active {
  -webkit-transition: all 0.3s ease-out;
  -moz-transition: all 0.3s ease-out;
  -o-transition: all 0.3s ease-out;
  transition: all 0.3s ease-out;
  -webkit-transform: translateY(-100%);
  -moz-transform: translateY(-100%);
  -o-transform: translateY(-100%);
  transform: translateY(-100%);
}
.slide-up-enter,
.slide-up-leave-to {
  -webkit-transform: translateY(0);
  -moz-transform: translateY(0);
  -o-transform: translateY(0);
  transform: translateY(0);
}

2. Hardware performance issues of Xiaomi 8

Another reason that may cause the animation effect to fail to display properly is that of Xiaomi 8 Hardware performance issues. On high-end mobile phones like Xiaomi 8, hardware performance is not a problem, but some users may install too many applications, or have some applications that occupy high system resources running, resulting in uneven distribution of system resources and resulting in animation effects. Unable to display properly.

Solution:

For hardware performance issues, we can optimize from the following aspects:

• Lazy pages or components that need to display animation effects Loading to avoid rendering all components at once when the page is loaded, resulting in excessive system resource usage;
• Disable some applications or services that occupy excessive system resources, such as applications and services running in the background.

3. Uniapp version problem

The last reason why the animation effect cannot be displayed normally is the uniapp version problem. If you are using an earlier version of uniapp, there may be deficiencies in compatibility. For example, some animation properties are not compatible, which will cause the animation effects to not be displayed properly.

Solution:

For the uniapp version problem, we can upgrade according to the actual situation:

• If you are using an earlier uniapp version, we can consider Upgrade to the latest version. The new version of uniapp usually optimizes compatibility to improve the performance of animation effects;
• If you are already using the latest uniapp version, we can learn about it by checking the official uniapp documentation, community, etc. Does the version have compatibility issues?

Summary:

In actual development, if we encounter the problem that the animation effect cannot be displayed normally, we need to analyze the possible reasons and make corresponding optimizations based on the actual situation. Through the introduction of this article, you should already know the possible reasons and solutions for why animation effects cannot be displayed normally on Xiaomi Mi 8 mobile phone. I hope it will be helpful to you.
