如何更改禁用按钮的文本颜色？

Question

Currently, I have something like this inside my view:

public void DisableNextBtn(object sender, TextChangedEventArgs e)
{
    if (String.IsNullOrEmpty(emailentry.Text))
    {
        NextButton.IsEnabled = false;
        NextButton.TextColor = Color.FromRgba(0xFF, 0xFF, 0xFF, 0x80);
    }
    else
    {
        NextButton.IsEnabled = true;
        NextButton.TextColor = Color.White;
    }
}

However, even though I want to set the TextColor of the button to the color above, it won't change from the default dark disabled state text color. How can I change the TextColor for my button?

I have a custom button already, so I was thinking maybe there is a way to change the textcolor of disabled state button inside my custom renderer but I'm not entirely sure.

This is for Xamarin.Forms Android app.

Answer 1

            btn.SetTextColor(Color.Rgb(0:255, 0:255, 0:255));

Answer 2

mBtnEmail.setTextColor(ContextCompat.getColor(getContext(), R.color.text_gray));

Answer 3

In xamarin forms android, I just did this in my styles.xml for my disabled textcolor . I'm sure it's the same for button textcolor .

<item name="android:textColor">@android:color/black</item>

Answer 4

You can change it using NextButton.ForeColor = Color.FromRgba(0xFF, 0xFF, 0xFF, 0x80);.

Answer 5

if you'd like to change the color so it becomes like the color of it background, wich means you want to hide the text, you can do:

button1.Text = "";
button1.Enabled = true;
