如何创建一个从左到右缓慢填充5,10或??的条形区域？秒？
Ala*_*an2 6 xamarin xamarin.forms
我有一个带有计时器的应用程序,可以在1到300秒之间计时.目前,我将剩余时间显示为每秒倒计时的数字.它是通过绑定标签完成的vm.Timer
App.Timer1Seconds = 10; // the value is set in code
// just using 10 as an example here
while (App.Timer1Seconds > 0)
{
vm.Timer = App.Timer1Seconds.ToString();
try
{
await Task.Delay(1000, App.tokenSource1.Token);
}
catch (TaskCanceledException)
{
App.Timer1Seconds = 0;
}
App.Timer1Seconds--;
}
我想要做的是用屏幕顶部和网格内的条形区域替换它,使它看起来像这样:
*********************
然后
********************
然后
*******************
然后
******************
随着时间的推移,条带的百分比从完全填充到没有任何东西以线性方式填充,可以是300到3秒.在检索页面时,有点类似于Web浏览器中的进度条,但在这种情况下,我知道活动的确切时间.
有没有人对如何创建它有任何想法？请注意,如果它需要自定义渲染器,那么我可以使用该解决方案.
更新:
我已经实施了Sharada的解决方案,但我有两个小问题:
这是我的XAML代码:
<Grid Grid.Row="3" Grid.Column="0" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" BackgroundColor="Aqua" RowSpacing="0" Padding="0">
<Grid.RowDefinitions>
<RowDefinition Height="2" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<local:TimerView Grid.Row="0" Grid.Column="0" StartTimerCommand="{Binding TimerStartCommand}" RemainingTime="{Binding TimeLeft}" HorizontalOptions="FillAndExpand" />
</Grid>
当它运行时,我希望进度条从右到左占据整个屏幕.但是它似乎只使用了大约10%的空间,如下所示:
|****** |
|***** |
|**** |
|*** |
|** |
|* |
你能否建议我如何能够让动画从屏幕的一侧移动到另一侧,然后像这样缩小尺寸:
|***************************************************************|
|************************************************************** |
|************************************************************* |
...
|** |
|* |
| |
我注意到后面的代码中没有timerView的定义.这是我添加的内容:
var timerView = new TimerView();
如果可以,请告诉我.
更新2:
这是该页面的完整代码.我仍然感到困惑的是,为什么标签没有从页面的一边填充到另一面:

正如@ hvaughan3建议的那样,可以使用ProgressBar控件.
但是,如果需要创建具有自定义外观和自定义动画的控件,则可以创建自己的自定义进度条.
public static class ViewExtensions
{
public static Task<bool> WidthTo(this VisualElement self, double toWidth, uint length = 250, Easing easing = null)
{
easing = easing ?? Easing.Linear;
var taskCompletionSource = new TaskCompletionSource<bool>();
var animation = new Animation(
callback: d => AbsoluteLayout.SetLayoutBounds(self, new Rectangle(0, 0, d, self.Height)),
start: self.Width,
end: toWidth,
easing: easing);
var offset = 1000;
animation.Commit(self, "WidthTo",
rate: Convert.ToUInt32(offset),
length: length,
finished: (v, c) => taskCompletionSource.SetResult(c)
);
return taskCompletionSource.Task;
}
}
下一步是创建一个扩展AbsoluteLayout并具有以下子控件的自定义控件:
进度条视图:将剩余进度表示为条形
轨迹栏视图:代表全长
计时器标签视图:将剩余进度时间表示为文本标签
自定义控件可用于DeviceTimer更新标签,同时使用上面的动画(如我们所定义)将进度条动画为空.
最后一步是创建一个触发计时器的命令.我们使用命令属性以使其对MVVM友好(即也可以通过视图模型触发).
public class TimerView : AbsoluteLayout
{
public TimerView()
{
//Load view when size has been allocated
SizeChanged += (sender, e) =>
{
if (Width == 0 || Height == 0)
return;
if (TrackBar == null || ProgressBar == null)
return;
Children.Clear();
//ensure track-bar gets full width and height as parent
SetLayoutFlags(TrackBar, AbsoluteLayoutFlags.SizeProportional);
SetLayoutBounds(TrackBar, new Rectangle(0, 0, 1, 1));
Children.Add(TrackBar);
//ensure progress-bar gets full height, but width can be changed
SetLayoutFlags(ProgressBar, AbsoluteLayoutFlags.None);
SetLayoutBounds(ProgressBar, new Rectangle(0, 0, Width, Height));
Children.Add(ProgressBar);
//if timer-label available, ensure it gets full width and height
if (TimerLabel != null)
{
SetLayoutFlags(TimerLabel, AbsoluteLayoutFlags.SizeProportional);
SetLayoutBounds(TimerLabel, new Rectangle(0, 0, 1, 1));
Children.Add(TimerLabel);
TimerLabel.SetBinding(BindingContextProperty, new Binding(nameof(RemainingTime), source: this));
}
if (AutoStart != default(TimeSpan))
{
RemainingTime = AutoStart;
StartTimerCommand.Execute(RemainingTime);
}
};
StartTimerCommand = new Command(async (timer) =>
{
if (!IsEnabled)
return;
//reset progress-bar width
SetLayoutBounds(ProgressBar, new Rectangle(0, 0, Width, Height));
if (timer != null && timer is TimeSpan)
RemainingTime = (TimeSpan)timer;
IsEnabled = false;
//Start timer for label update
var ctrlTobeUpdated = this;
Device.StartTimer(TimeSpan.FromSeconds(1), () =>
{
var oneSecond = TimeSpan.FromSeconds(1);
ctrlTobeUpdated.RemainingTime -= oneSecond;
if (ctrlTobeUpdated.RemainingTime < oneSecond)
{
ctrlTobeUpdated = null;
return false;
}
else
return true;
});
//Start animation
await ProgressBar.WidthTo(0, Convert.ToUInt32(RemainingTime.TotalMilliseconds));
IsEnabled = true;
});
}
public static readonly BindableProperty TrackBarProperty =
BindableProperty.Create(
"TrackBar", typeof(View), typeof(TimerView),
defaultValue: null);
public View TrackBar
{
get { return (View)GetValue(TrackBarProperty); }
set { SetValue(TrackBarProperty, value); }
}
public static readonly BindableProperty ProgressBarProperty =
BindableProperty.Create(
"ProgressBar", typeof(View), typeof(TimerView),
defaultValue: null);
public View ProgressBar
{
get { return (View)GetValue(ProgressBarProperty); }
set { SetValue(ProgressBarProperty, value); }
}
public static readonly BindableProperty TimerLabelProperty =
BindableProperty.Create(
"TimerLabel", typeof(Label), typeof(TimerView),
defaultValue: default(Label));
public Label TimerLabel
{
get { return (Label)GetValue(TimerLabelProperty); }
set { SetValue(TimerLabelProperty, value); }
}
public static readonly BindableProperty StartTimerCommandProperty =
BindableProperty.Create(
"StartTimerCommand", typeof(ICommand), typeof(TimerView),
defaultBindingMode: BindingMode.OneWayToSource,
defaultValue: default(ICommand));
public ICommand StartTimerCommand
{
get { return (ICommand)GetValue(StartTimerCommandProperty); }
set { SetValue(StartTimerCommandProperty, value); }
}
public static readonly BindableProperty RemainingTimeProperty =
BindableProperty.Create(
"RemainingTime", typeof(TimeSpan), typeof(TimerView),
defaultBindingMode: BindingMode.OneWayToSource,
defaultValue: default(TimeSpan));
public TimeSpan RemainingTime
{
get { return (TimeSpan)GetValue(RemainingTimeProperty); }
set { SetValue(RemainingTimeProperty, value); }
}
public static readonly BindableProperty AutoStartProperty =
BindableProperty.Create(
"AutoStart", typeof(TimeSpan), typeof(TimerView),
defaultValue: default(TimeSpan));
public TimeSpan AutoStart
{
get { return (TimeSpan)GetValue(AutoStartProperty); }
set { SetValue(AutoStartProperty, value); }
}
}

}
}
}
编辑 - 2:根据问题更新
如果你需要一个动画,它首先从一个瞬间从左到右然后再回到左边; 这也可以通过控制中的微小更新来实现.
然后,您将需要更新SizeChanged处理程序和StartTimer处理程序,如下所示:
public class TimerView : AbsoluteLayout
{
public TimerView()
{
SizeChanged += (sender, e) =>
{
if (Width == 0 || Height == 0)
return;
if (TrackBar == null || ProgressBar == null)
return;
Children.Clear();
SetLayoutFlags(TrackBar, AbsoluteLayoutFlags.SizeProportional);
SetLayoutBounds(TrackBar, new Rectangle(0, 0, 1, 1));
Children.Add(TrackBar);
SetLayoutFlags(ProgressBar, AbsoluteLayoutFlags.None);
SetLayoutBounds(ProgressBar, new Rectangle(0, 0, 0, Height));
Children.Add(ProgressBar);
if(TimerLabel != null)
{
SetLayoutFlags(TimerLabel, AbsoluteLayoutFlags.SizeProportional);
SetLayoutBounds(TimerLabel, new Rectangle(0, 0, 1, 1));
Children.Add(TimerLabel);
TimerLabel.SetBinding(BindingContextProperty, new Binding(nameof(RemainingTime), source: this));
}
};
StartTimerCommand = new Command(async (timer) =>
{
if (!IsEnabled)
return;
if (timer != null && timer is TimeSpan)
RemainingTime = (TimeSpan)timer;
IsEnabled = false;
var ctrlTobeUpdated = this;
Device.StartTimer(TimeSpan.FromSeconds(1), () =>
{
var oneSecond = TimeSpan.FromSeconds(1);
ctrlTobeUpdated.RemainingTime -= oneSecond;
if (ctrlTobeUpdated.RemainingTime < oneSecond)
{
ctrlTobeUpdated = null;
return false;
}
else
return true;
});
await ProgressBar.WidthTo(Width, Convert.ToUInt32(150));
await ProgressBar.WidthTo(0, Convert.ToUInt32(RemainingTime.TotalMilliseconds - 150));
IsEnabled = true;
});
}
编辑 - 3:删除了ProgressBar和,和的可绑定属性定义中的默认值的代码/支持TimerBar.
编辑 - 4:在加载时添加对自动启动计时器的支持.
示例用法4:自动启动计时器
XAML
<local:TimerView AutoStart="0:0:20"> <!-- timespan for 20 seconds or VM based AutoStart="{Binding SetTime}" -->
<local:TimerView.ProgressBar>
<BoxView BackgroundColor="Maroon" />
</local:TimerView.ProgressBar>
<local:TimerView.TrackBar>
<BoxView BackgroundColor="Gray" />
</local:TimerView.TrackBar>
</local:TimerView>
编辑 - 5:添加对计时器的暂停和停止命令的支持.此外,更新的计时器视图在设备方向更改方面更具弹性.
