错误在Android库项目中使用TextInputLayout

Question

我想在Android库项目中使用TextInputLayout。但是，我在设计使用XML的布局时遇到了错误，并且在执行该项目时出现了'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> 

在版面设计窗口还我得到以下错误

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

项目minSDK是16，targetSDK是24和compileSDK是24与构建工具版本24.0.1。此外，我还在应用程序和库模块中添加了下面的gradle依赖关系。

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' 

Answer 1

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> 

确保您的应用程序使用程序兼容性主题

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

或其他延伸它像Theme.AppCompat.Light.DarkActionBar

最后，AndroidManifest.xml中：

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

Answer 2

最后将一个AppCompat主题直接添加到TextInputLayout使其正常工作。我只是遵循以下提到的职位提供的解决方案，

TextInputLayout AppCompat Theme

我更新了我的布局文件如下面，

<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 3

您的活动必须延伸AppCompatActivity。然后只有它为我工作。
