[英]How can I get the selected time from my timepicker and assign it to a TextBox value?
[英]Get Selected Time from TimePicker in Xamarin Android
因為他們說 Java 可以做的任何事情,C# 可以做得更好......決定在 Xamarin Android 中設計一個警報應用程序,我似乎無法在 C# 中獲得所選時間的值......一個稱為 triggerTime 的變量應該播放一些音樂或在鬧鍾時間成熟時顯示警報對話框需要該值...這是 TimePicker 的 xml...
<TimePicker
android:id="@+id/timePicker1"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
這是在 AlarmActivity.cs 中定義了時間選擇器的 C# 代碼
base.OnCreate(savedInstanceState);
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
SetContentView(Resource.Layout.Alarm);
TimePicker timePicker2 = this.FindViewById<TimePicker>(Resource.Id.timePicker1);
//Code to getTime that user selects
謝謝您的幫助
Xamarin 提供了使用TimePicker的完整示例
基本上,你需要實現IOnTimeSetListener
具有OnTimeSet
方法
public void OnTimeSet(TimePicker view, int hourOfDay, int minute)
{
// hourOfDate and minute are the user's selected values
}
您可以使用TimeChanged
事件來獲取時間選擇器更改的時間。
xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TimePicker
android:id="@+id/timePicker1"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/timePicker1"/>
</RelativeLayout>
后面的代碼:
TextView textView = FindViewById<TextView>(Resource.Id.textView1);
TimePicker timePicker1 = FindViewById<TimePicker>(Resource.Id.timePicker1);
timePicker1.TimeChanged += delegate
{
var h = timePicker1.CurrentHour;
var m = timePicker1.CurrentMinute;
textView.Text = h + ":" + m;
};
