将新的TextInputLayout用于EditText的渲染问题 [英] Rendering problems using new TextInputLayout for EditText

问题描述

我正在尝试设置新的support.desing库，该库为旧的android版本提供一些棒棒糖的视觉效果.

I'm trying to set the new support.desing library that provides some lollipop visual effects to old android versions.

在这种情况下，我试图为edittext添加浮动标签，这是通过widget.TextInputLayout完成的:

In this case, I'm triying to add the floating labels for the edittext, which is done with the widget.TextInputLayout:

为此，我遵循了Google提供的一些指示:

To do this I have followed google's provided few indications:

• 我已经下载了最后一个支持库(22.2.0)，并包含在graddle文件中.

• I have downloaded the last support library (22.2.0) and included on graddle file.

编译'com.android.support:design:22.2.0'

compile 'com.android.support:design:22.2.0'

我已经通过以下方式在xml中添加了TextInputLayout:

I have added the TextInputLayout in my xml this way:

<android.support.design.widget.TextInputLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="30dp"
    android:layout_marginLeft="20dp">

    <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ems="12"
        android:hint="hint"
        android:inputType="number"
        android:id="@+id/edt" />
</android.support.design.widget.TextInputLayout>

但是Android Studio在布局预览中显示了此信息:

But Android Studio is showing this in the layout preview:

Rendering failed with a known bug. Please try a rebuild.  
The following classes could not be instantiated:
- android.support.design.widget.TextInputLayout (Open Class, Show Exception, Clear Cache)

Exception Details 
java.lang.NoSuchFieldError: TextAppearance

这是我正在使用的样式:

This is the style I'm using:

<style name="MaterialTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/md_red_500</item>
    <item name="colorPrimaryDark">@color/darkPrimaryColor</item>
    <item name="colorAccent">@color/md_green_500</item>
    <item name="android:textColorPrimary">@color/md_grey_900</item>
    <item name="android:textColorSecondary">@color/md_grey_600</item>
</style>

推荐答案

已解决.必须添加:

<android.support.design.widget.TextInputLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="30dp"
            android:layout_marginLeft="20dp"
            app:hintTextAppearance="@style/TextAppearence.App.TextInputLayout">

这就是这里:

<style name="TextAppearence.App.TextInputLayout" parent="@android:style/TextAppearance">
    <item name="android:textColor">@color/accentColor</item>
</style>
