How to create two line TextView on Android?

Question

I'm making app with using Xamarin.forms.

My problem is there is no way to create TWO line TextView. The text will be automatically go to next line even if I set enough width.

If I want to create single line, I set singleline property as true and setMaxLine as 1.

But the Two line, If I set both of LineNumber and MaxLineNumber, it does not work. Text will makes third line. for example, if text value is "I'm a baby not robot.\\nPlease give me a milk", it goes like

I'm a baby not robot.
Please give me 
a milk

How to solve this problem?

Thanks.

By default all the EditText widgets in Android are multi-lined.

Here is some sample code:

<EditText
    android:inputType="textMultiLine" <!-- Multiline input -->
    android:lines="8" <!-- Total Lines prior display -->
    android:minLines="6" <!-- Minimum lines -->
    android:gravity="top|left" <!-- Cursor Position -->
    android:maxLines="10" <!-- Maximum Lines -->
    android:layout_height="wrap_content" <!-- Height determined by content -->
    android:layout_width="fill_parent" <!-- Fill entire width -->
    android:scrollbars="vertical" <!-- Vertical Scroll Bar -->
/>

Here is what works for me

<TextView
    android:text="I'm a baby not robot.\nPlease give me a milk"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/textView1"
    android:singleLine="false"
    android:maxLines="10" />

But the Two line, If I set both of LineNumber and MaxLineNumber, it does not work. Text will makes third line.

You can create a custom label control and consume it in your Xaml:

CustomLabel:

public class CustomLabel:Label
{
}

Xaml:

<ContentPage ...
         xmlns:local="clr-namespace:LabelDemo"
         ...>
<local:CustomLabel Text="I'm a baby not robot. \nPlease give me a milk"  VerticalOptions="Center" HorizontalOptions="Center" />

Then create a custom renderer in your Droid project like below:

using Android.Widget;
using Xamarin.Forms.Platform.Android;
using Xamarin.Forms;
[assembly:ExportRenderer(typeof(LabelDemo.CustomLabel),typeof(LabelDemo.Droid.MyLabelRenderer))]
namespace LabelDemo.Droid
{
    public class MyLabelRenderer:LabelRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<Label> e)
        {
            base.OnElementChanged(e);
            if (Control != null)
            {
                var text = Control.Text;
                text = text.Replace("\\n", "\n");//"\n" in shared project will be automatically transformed into "\\n", so we need to change it back
                Control.SetLines(2);
                Control.SetText(text, TextView.BufferType.Normal);
            }
        }
    }
}
