Question

这是我的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>

这就是风格

<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>

我找不到像hintSize，textSize和keyTextSize这样的东西没有帮助

Answer 1

在styles.xml中

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

然后在你的布局文件中：

<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">

Answer 2

以XML格式更改TextInputLayout＆＃39; app:errorTextAppearance。

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

CustomTextInputLayoutStyle.ErrorTextStyle中将styles.xml定义为

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

Answer 3

1）使用样式

将hintTextAppearance添加到InputLayout

<android.support.design.widget.TextInputLayout xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"     
    android:layout_height="wrap_content"
    app:hintTextAppearance="@style/TextInputLayoutHintText" >
    <android.support.design.widget.TextInputEditText            
        android:layout_width="match_parent"              
        android:layout_height="wrap_content"
        android:textSize="16sp" />
</android.support.design.widget.TextInputLayout>

2）然后只需将样式添加到styles.xml

<style name="TextInputLayoutHintText">
   <item name="android:textColor">@color/gray</item>
   <item name="android:textSize">12sp</item></style>

Answer 4

@SantiagoMartínez答案仅适用于非空Edittext（在TextInputLayout内部）的提示

但是对于空的Edittext，TextInputLayout提示从Edittext textSize获得属性。

Answer 5

您可以减少EditText上的字体大小 - 这也会减小提示的大小。即android：textSize =＆＃34; 16sp＆＃34;
