EditText Edit Feature in MVVMCross

Question

I wonder how could I able to enable and disable edit feature in the EditText in mvvmcross.

<EditText
   style="@style/InputNumbersEditText"
   android:layout_weight="1"
   android:layout_width="0dp"
   android:focusable="true"
   android:layout_height="wrap_content"
   android:inputType="numberDecimal|numberSigned"
   local:MvxBind="Text Age" />

Answer 1

Since android:editable="false" is deprecated, you should set android:inputType="none" to disable input on the EditText. If you're looking to bind the inputType of the EditText with MvvmCross, you can create a Value Converter which takes an input value from your ViewModel, and returns an answer of type Android.Text.InputTypes.

Example implementation:

Add a class to your Android project with the following in it:

public class EditTextEnabledValueConverter : MvxValueConverter<bool, InputTypes>
{
    protected override InputTypes Convert(bool value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value)
            return InputTypes.ClassNumber | InputTypes.NumberFlagDecimal | InputTypes.NumberFlagSigned;

        return InputTypes.Null;
    }
}

and in your layout file:

<EditText
   style="@style/InputNumbersEditText"
   android:layout_weight="1"
   android:layout_width="0dp"
   android:focusable="true"
   android:layout_height="wrap_content"
   local:MvxBind="Text Age; InputType EditTextEnabled(MyProperty)" />

Where MyProperty is a bindable boolean on your ViewModel. You can use any type as a source type, it doesn't have to be a boolean. Happy converting!
