Change TextInputLayout focused & unfocused hint color programmatically

问题

I wanted to change the color of hint in TEXT INPUT LAYOUT same when it is in focused or unfocused state.i have two TEXT INPUT LAYOUT fields.Both fields are same color.But it in focused state color appears but in an unfocused state the default grey color appears.i want to keep the color color of hint same in both focused and unfocused state.

   <com.example.viveka.snipeid.CustomTextInputLayout
        android:id="@+id/input_layout_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="15dp"
        app:errorEnabled="true"
        >
    <EditText
        android:id="@+id/editEmail"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:hint="email / snipe id"
        android:digits="abcdefghijklmnopqrstuvwxyz.@0123456789"
        android:textAllCaps="false"
        android:textSize="12sp"
        android:layout_marginLeft="-4dp"

You can do like this.

android:textColorHint="#FF0000" was EditText's hint color.

If you want the text color as well as the hint color.

You can change android:textColor="#FF0000" in the EditText.

You can add app:errorTextAppearance="@style/text_in_layout_error_hint_Style" to change the error text color.

<com.example.viveka.snipeid.CustomTextInputLayout
    android:id="@+id/input_layout_name"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="15dp"
    android:textColorHint="#FF0000"
    app:errorTextAppearance="@style/text_in_layout_error_hint_Style"
    app:hintTextAppearance="@style/text_in_layout_hint_Style"
    app:errorEnabled="true">

    <EditText
        android:id="@+id/editEmail"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_marginLeft="-4dp"
        android:digits="abcdefghijklmnopqrstuvwxyz.@0123456789"
        android:hint="email / snipe id"
        android:textAllCaps="false"
        android:textColor="#FF0000"
        android:textColorHint="@color/primary"
        android:textSize="12sp"/>
</com.example.viveka.snipeid.CustomTextInputLayout>

The LEFT-TOP hint color depended on app:hintTextAppearance="@style/text_in_layout_hint_Style".

And the style code:

<style name="text_in_layout_hint_Style">
    <item name="android:textColor">#FF0000</item>
    <item name="android:textSize">12sp</item>
</style>

Add error text style

 <style name="text_in_layout_error_hint_Style">
    <item name="android:textColor">#00ff00</item>
    <item name="android:textSize">12sp</item>
</style>

like this: Hope to help you.
