How to change the hint size of TextInputLayout

Question

This is my xml

<android.support.design.widget.TextInputLayout                 style="@style/main_input_text"                 android:layout_marginTop="@dimen/activity_medium_margin"                 app:hintTextAppearance="@style/TextAppearence.App.TextInputLayout">                  <android.support.v7.widget.AppCompatEditText                     style="@style/main_edit_text"                     android:inputType="text" />  </android.support.design.widget.TextInputLayout> 

And this is style

<style name="main_input_text">         <item name="android:layout_width">match_parent</item>         <item name="android:layout_height">@dimen/activity_edittext_height</item>         <item name="android:background">@drawable/mc_shape_border_button_transparent</item>         <item name="android:gravity">center_vertical</item>         <item name="android:paddingTop">@dimen/activity_extra_small_margin</item>         <item name="android:paddingBottom">@dimen/activity_extra_small_margin</item>         <item name="android:keyTextSize">8sp</item>         <item name="android:textSize">8sp</item> </style> 

I don't find something like hintSize, textSize and keyTextSize not helping

Answer 1

In your styles.xml

<style name="TextLabel" parent="TextAppearance.Design.Hint">     <item name="android:textSize">16sp</item> </style> 

And then in your layout file:

<android.support.design.widget.TextInputLayout          android:layout_width="match_parent"          android:layout_height="wrap_content"          android:layout_marginLeft="@dimen/activity_horizontal_margin"          android:layout_marginRight="@dimen/activity_horizontal_margin"          android:layout_marginTop="12dp"          app:hintTextAppearance="@style/TextLabel"          android:minHeight="30dp">

Change the TextInputLayout's app:errorTextAppearance in XML.

<android.support.design.widget.TextInputLayout             android:layout_width="wrap_content"             android:layout_height="wrap_content"             app:errorTextAppearance="@style/CustomTextInputLayoutStyle.ErrorTextStyle"> 

Where CustomTextInputLayoutStyle.ErrorTextStyle is defined in styles.xml as

<style name="CustomTextInputLayoutStyle.ErrorTextStyle" parent="TextAppearance.Design.Error">         <item name="android:textSize">10sp</item> </style>
