Android entry remove bottom line

[FM1973]

Hello.

.net 7 brought back the bottom line on android entries.
Our customer doesn´t like that.
Is there a way to remove the bottom line or at least set it´s color to transparent?

Thanks for your help!

You could try handlers?, but this may mean that some of the functionality would not be available.

You can modify how the EntryHandler creates EditText controls - put something like this in your MauiProgram.cs:

#if __ANDROID__
EntryHandler.PlatformViewFactory = (h) => {
	var editText = new AndroidX.AppCompat.Widget.AppCompatEditText(h.Context);
	editText.Background = null;
	editText.SetBackgroundColor(Android.Graphics.Color.Transparent);
	return editText;
};
#endif

Thanks for your help.
I did the following in MauiProgram.cs

`private static void SetHandler()
{

    Microsoft.Maui.Handlers.EntryHandler.Mapper.AppendToMapping("MyCustomization", (handler, view) =>
    {
        if (view is Entry)
        {

#if ANDROID
handler.PlatformView.Background = null;
#endif
}
});

}`

This works.
Thanks a lot!

Net7 also now adds underline to a maui picker before it is clicked, any ideas? Thanks.

The MAUI Picker is rendered on Android as a MauiPicker, which is actually an AppCompatEditText: https://github.com/dotnet/maui/blob/0062faeba1dd391b1468798cd29299403b9b67f0/src/Core/src/Platform/Android/MauiPicker.cs

Because the MauiPicker is an AppCompatEditText, it gets the same underlining styling on Android as any other EditText control.

So you can modify that by doing something like this (not exact code, probably) in MauiProgram.cs:

#if __ANDROID__
PickerHandler.PlatformViewFactory = (h) => {
	var picker = new MauiPicker(h.Context);
	picker.Background = null;
	picker.SetBackgroundColor(Android.Graphics.Color.Transparent);
	return picker;
};
#endif

Many thanks, works fine. I thought I had tried the MauiPicker, must have done something wrong as it didn't compile, oh well live and learn.
Thanks again.

What if I only want to change a certain entry separately? Your method is globally effective. @hartez

Then you would need to subclass Entry and add a property to handle this. Or, alternatively, modify the EntryHandler mapping to check for a condition before applying the transparent background.

For me it will works with BackgroundTintList.

Microsoft.Maui.Handlers.EditorHandler.Mapper.AppendToMapping("SetUpEntry", (handler, view) =>
{
#if ANDROID
handler.PlatformView.Background = null;
handler.PlatformView.BackgroundTintList = ColorStateList.ValueOf(Android.Graphics.Color.Transparent);
#endif
});
