How to use the method to set the progress bar in Xamarin XAML language
This article will explain in detail how to use the method to set the progress bar in the Xamarin XAML language. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.
A ProgressTo method is defined in ProgressBar, which can also be used to set the current progress bar. The difference between ProgressTo and Progress properties is that ProgressTo provides animation. The ProgressTo method must be used in the code file, not in the XAML file. Its grammatical form is as follows:
ProgressBarObject. ProgressTo (value, length, easing)
The parameters are described as follows:
Value: indicates the current progress of the setting.
Length: indicates how long it takes to reach the set value (milliseconds).
Easing: represents the animation effect.
[example 12-9:ProgressBarProgressThree] the following will use the ProgressTo method to set the current progress of the progress bar. The specific steps are as follows:
(1) MainPage.xaml file, write code, layout the content page. The code is as follows:
(2) Open the MainPage.xaml.cs file, write code, and set the current progress of the progress bar. The code is as follows:
Using System
Using System.Collections.Generic
Using System.Linq
Using System.Text
Using System.Threading.Tasks
Using Xamarin.Forms
Namespace ProgressBarProgressThree
{
Public partial class MainPage: ContentPage
{
Public MainPage ()
{
InitializeComponent ()
}
/ / set the current progress of the progress bar
Void SetProgresse (object sender, EventArgs args)
{
ProgressBar.ProgressTo (1.0,2500, Easing.Linear)
}
}
}
When you run the program at this point, you will see the effect shown in figure 12.32-12.33. When the developer taps the PlayProgressAnimate button, the progress bar implements the loaded animation, similar to the one shown in figure 12.34-12.35. The loading animation is completed after 2.5 seconds, and the current progress of the progress bar will be 1.
