Programmatically set TextInputLayout Hint Text Color and Floating Label Color

Question

I use a TextInputLayout, I would want to programmatically set the hint text color and the floating label color if the input field is mandatory. Before moving to TextInputLayout I used to set the hint text color programmatically using the following

textField.setHintTextColor(Color.RED);

Can someone guide me on how to set the hint text color and the floating label color programmatically for a TextInputLayout.

In the screenshot attached i would want the hint text Address 1 to be in red when not focused and the on focus the floating label Address 1 should be in red.

I changed focused color with reflection. Here's the snippet it may help someone.

private void setUpperHintColor(int color) {
    try {
        Field field = textInputLayout.getClass().getDeclaredField("mFocusedTextColor");
        field.setAccessible(true);
        int[][] states = new int[][]{
                new int[]{}
        };
        int[] colors = new int[]{
                color
        };
        ColorStateList myList = new ColorStateList(states, colors);
        field.set(textInputLayout, myList);

        Method method = textInputLayout.getClass().getDeclaredMethod("updateLabelState", boolean.class);
        method.setAccessible(true);
        method.invoke(textInputLayout, true);

    } catch (Exception e) {
        e.printStackTrace();
    }
}

EDIT 2018-08-01:

If you are using design library v28.0.0 and later, fields had changed from mDefaultTextColorto defaultHintTextColor and from mFocusedTextColor to focusedTextColor.

Check decompiled class for other fields.

With the Material Components library you can use:

In the layout:

<com.google.android.material.textfield.TextInputLayout
    app:hintTextColor="@color/mycolor"
    android:textColorHint="@color/text_input_hint_selector"
    .../>

in a style:

<style name="..." parent="Widget.MaterialComponents.TextInputLayout.FilledBox">
    <!-- The color of the label when it is collapsed and the text field is active -->
    <item name="hintTextColor">?attr/colorPrimary</item>
    <!-- The color of the label in all other text field states (such as resting and disabled) -->
    <item name="android:textColorHint">@color/mtrl_indicator_text_color</item>
</style>

in the code:

// Sets the text color used by the hint in both the collapsed and expanded states
textInputLayout.setDefaultHintTextColor(...);

//Sets the collapsed hint text color
textInputLayout.setHintTextColor(....);

Please, take a good look at the documentation here: TextInputLayout Methods

There is a method :

setHintTextAppearance(int resId)

Which takes a resource id that could be a style resource!

I would try this and see how it goes!

I hope it helps you!
