问题描述
我正在对条目进行自定义控件。我希望当您打开键盘时，该图标会出现在键盘上。
我看到可以通过将InputType设置为Android.Text.InputTypes.TextvariationShortMessage来完成此操作。 Android.Text.InputTypes.Classtext。问题是我不知道如何使用自定义控件来实现它。
自定义控件xaml：
<Entry
x:Name="EntryControl"
Margin="45,0"
Keyboard="Chat"
Placeholder="{Binding Placeholder}"
Text="{Binding EntryText}"
WidthRequest="320" />自定义控件xaml.cs：
public partial class CKEditor : ContentView

public CKEditor()
{

BindableProperty.Create("EmojiItemSource",typeof(IList),typeof(CKEditor));
public IList EmojiItemSource
{

set { SetValue(EmojiItemSourceProperty,value); }
}
//===============Border Color=====================
public static readonly BindableProperty BorderColorProperty =
BindableProperty.Create("BorderColor",typeof(Color),typeof(CKEditor));
public Color BorderColor

get { return (Color)GetValue(BorderColorProperty); }
set { SetValue(BorderColorProperty,value); }

public static readonly BindableProperty CornerRadiusProperty =
BindableProperty.Create("CornerRadius",typeof(int),typeof(CKEditor));

public ImageSource LeftSideIcon
{

set { SetValue(LeftSideIconProperty,value); }
}
//===============Placeholder=====================
public static readonly BindableProperty PlaceholderProperty =
BindableProperty.Create("Placeholder",typeof(CKEditor));
public string Placeholder
{
get { return (string)GetValue(PlaceholderProperty); }

解决方法
您提供的屏幕截图需要使用自定义键盘。由于Android和iOS平台的限制，如果不创建自己的键盘是不可能的。
我们可以创建自己的键盘视图，包括一些表情符号作为按钮以及一些其他控件。并将TapGestureRecognizer添加到图像中。当触发此事件时，它将显示您的自定义键盘视图。
