如何更改TextInputLayout中的浮動標籤顏色

Question

我試圖更改浮動標籤「電子郵件」的顏色，如屏幕截圖中所示。

這裏是佈局XML的內容：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context="com.premedios.streetler.LoginActivity"> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="150dp" 
    android:orientation="vertical" 
    android:layout_marginTop="10dp"> 

    <ImageView 
     android:layout_width="match_parent" 
     android:layout_height="150dp" 
     android:src="@drawable/logo"/> 

</LinearLayout> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center_horizontal" 
    android:layout_marginLeft="20dp" 
    android:layout_marginRight="20dp" 
    android:orientation="vertical"> 
    <android.support.design.widget.TextInputLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:theme="@style/TextLabel"> 
     <EditText 
      android:id="@+id/email" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:hint="@string/email_hint"/> 
    </android.support.design.widget.TextInputLayout> 
    <android.support.design.widget.TextInputLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:theme="@style/TextLabel"> 
     <EditText 
      android:id="@+id/password" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:hint="@string/password_hint"/> 
    </android.support.design.widget.TextInputLayout> 
    <Button 
     android:id="@+id/login" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginTop="20dp" 
     android:background="@color/colorText" 
     android:text="@string/LoginButtonText" 
     android:textColor="@color/colorPrimaryDark" 
     android:textSize="20sp"/> 
    <com.facebook.login.widget.LoginButton 
     android:id="@+id/facebook_login_button" 
     android:layout_gravity="center_horizontal" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:height="44dp" 
     android:visibility="gone"/> 
    <TextView 
     android:id="@+id/signup" 
     android:layout_width="match_parent" 
     android:layout_height="44dp" 
     android:layout_marginTop="10dp" 
     android:gravity="center" 
     android:text="@string/register_link_text" 
     android:textSize="18sp"/> 
</LinearLayout> 

我想改變這種浮動標籤顏色一樣的提示顏色。任何幫助讚賞。

使用this link

<style name="TextLabel" parent="TextAppearance.AppCompat"> 
<!-- Hint color and label color in FALSE state --> 
<item name="android:textColorHint">@color/Color Name</item> 
<item name="android:textSize">20sp</item> 
<!-- Label color in TRUE state and bar color FALSE and TRUE State --> 
<item name="colorAccent">@color/Color Name</item> 
<item name="colorControlNormal">@color/Color Name</item> 
<item name="colorControlActivated">@color/Color Name</item> 

你只需要使用這種風格在textInputLayout
