在Android Library项目中使用TextInputLayout时出错

Question

我正在尝试在Android库项目中使用TextInputLayout。 但是我在使用XML设计布局时遇到错误，并且在执行项目时也出现了“ android.view.InflateException”。 我的XML布局文件是

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/root"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <CustomViewPager
        android:id="@+id/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true" />

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:gravity="bottom">

        <android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:focusable="true"
                android:focusableInTouchMode="true"
                android:imeOptions="actionDone"
                android:inputType="textNoSuggestions" />
        </android.support.design.widget.TextInputLayout>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Skip"/>
    </RelativeLayout>
</RelativeLayout>

在布局设计窗口中，我也得到以下错误

java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library.

带有构建工具版本24.0.1的项目minSDK是16，targetSDK是24，compileSDK是24。 另外，我还在应用程序和库模块中添加了以下gradle依赖项。

compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.android.support:design:24.2.1'
compile 'com.android.support:support-v4:24.2.1'

最后，将AppCompat主题直接添加到TextInputLayout可以使其正常工作。 我只是按照以下提到的帖子中提供的解决方案进行操作，

TextInputLayout AppCompat主题

我如下更新了布局文件，

<android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/Theme.AppCompat">

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:imeOptions="actionDone"
            android:inputType="textNoSuggestions" />
    </android.support.design.widget.TextInputLayout>

Answer 2

您应该使用TextInputEditText内TextInputLayout

 <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <android.support.design.widget.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

 </android.support.design.widget.TextInputLayout>

确保您的应用使用AppCompat主题

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

或其他扩展它的主题（如Theme.AppCompat.Light.DarkActionBar

最后，AndroidManifest.xml：

<application android:theme="@style/AppTheme">

Answer 3

您的活动必须扩展AppCompatActivity。 然后只有它对我有用。
