I am thinking if i can change font size for placeholder on EntryCell
without change fontSize
for Text on EntryCell
?
Is There away to change font size for Placeholder without change font size for Text
Code = new EntryCell { Label = "Code:*", Text = "", Keyboard = Keyboard.Default, Placeholder = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" };
Here is a custom renderer for android. Here I'm modifying the HintTextColor(placeholder). You can modify the font in a similar way.
using System;
using Xamarin.Forms.Platform.Android;
using Xamarin.Forms;
using communityhealth;
using Android.Graphics;
using communityhealth.Android;
[assembly: ExportRenderer (typeof (MyUsernameEntry), typeof (MyUsernameEntryRenderer))]
[assembly: ExportRenderer (typeof (MyPasswordEntry), typeof (MyPasswordEntryRenderer))]
[assembly: ExportRenderer (typeof (MyEntry), typeof (MyEntryRenderer))]
namespace communityhealth.Android
{
public class MyEntryRenderer : EntryRenderer
{
protected override void OnElementChanged (ElementChangedEventArgs<Entry> e)
{
base.OnElementChanged (e);
if (e.OldElement == null) { // perform initial setup
// lets get a reference to the native control
var nativeEditText = (global::Android.Widget.EditText) Control;
// do whatever you want to the textField here!
nativeEditText.SetBackgroundColor(global::Android.Graphics.Color.Transparent);
nativeEditText.SetTextColor(global::Android.Graphics.Color.White);
Typeface font = Typeface.CreateFromAsset (Forms.Context.Assets, "Neris-Light.otf");
nativeEditText.TextSize = 14f;
nativeEditText.Typeface = font;
}
}
}
public class MyUsernameEntryRenderer : MyEntryRenderer
{
protected override void OnElementChanged (ElementChangedEventArgs<Entry> e)
{
base.OnElementChanged (e);
if (e.OldElement == null) {
// lets get a reference to the native control
var nativeEditText = (global::Android.Widget.EditText) Control;
nativeEditText.Hint = "Username";
nativeEditText.SetHintTextColor (global::Android.Graphics.Color.White);
nativeEditText.TextSize = 18f;
}
}
}
public class MyPasswordEntryRenderer : MyEntryRenderer
{
protected override void OnElementChanged (ElementChangedEventArgs<Entry> e)
{
base.OnElementChanged (e);
if (e.OldElement == null) {
// lets get a reference to the native control
var nativeEditText = (global::Android.Widget.EditText) Control;
nativeEditText.Hint = "Password";
nativeEditText.SetHintTextColor (global::Android.Graphics.Color.White);
nativeEditText.TextSize = 18f;
}
}
}
}
Unfortunately, no.
There is no API in Forms to change the Placeholder font size. Instead, you could create your own custom control to do this, or use a custom renderer to modify the placholder in the native view.
