Question

Я пытаюсь использовать TextInputLayout с Theme.material и код выглядеть ....

activity_mail.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    xmlns:drawableLeft="http://schemas.android.com/apk/res-auto" 
    android:background="#2196F3" 
    android:orientation="vertical" 
    android:scrollbarAlwaysDrawVerticalTrack="true" 
    tools:context="com.realmilk.MainActivity"> 

    <TextView 
     android:id="@+id/login_title" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginBottom="16dp" 
     android:layout_marginTop="22dp" 
     android:gravity="center_horizontal" 
     android:text="Account Login" 
     android:textColor="#fff" 
     android:textSize="26sp" 
     android:textStyle="bold" /> 

    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_below="@+id/login_title" 
     android:layout_marginTop="70dp" 
     android:background="#fff" 
     android:elevation="4dp" 
     android:orientation="vertical" 
     android:padding="20dp"> 

     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:orientation="vertical" 
      android:paddingTop="30dp"> 

      <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:drawableLeft="@drawable/ic_supervisor_account_black_24dp" 
        android:drawableTint="#FF4081" 
        android:singleLine="true" 
        android:hint="User Name" 
        android:inputType="textEmailAddress" /> 
      </android.support.design.widget.TextInputLayout> 

      <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:layout_marginTop="16dp" 
        android:singleLine="true" 
        android:drawableLeft="@drawable/ic_lock_black_24dp" 
        android:drawableTint="#FF4081" 
        android:hint="Password" 
        android:inputType="numberPassword" /> 
      </android.support.design.widget.TextInputLayout> 

      <TextView 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:layout_gravity="right" 
       android:paddingTop="5dp" 
       android:text="Forgot Password?" /> 


      <Button 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:layout_margin="22dp" 
       android:background="#d67601" 
       android:text="Sign in" 
       android:textAllCaps="false" 
       android:textColor="#fff" 
       android:textSize="18sp" /> 
     </LinearLayout> 
    </RelativeLayout> 

    <ImageButton 
     android:id="@+id/user_profile_photo" 
     android:layout_width="100dp" 
     android:layout_height="100dp" 
     android:layout_below="@+id/login_title" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="16dp" 
     android:background="@drawable/user_profile_image_background" 
     android:elevation="4dp" /> 

</RelativeLayout> 

MainActivity выглядеть следующим образом ..

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
    } 
} 

Когда я пытаюсь выполнить это

Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

Это было в con единственная, которую я наблюдал.

Может кто поможет мне найти, где я ошибся.

изменить следующие файлы

style.xml

<resources> 

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
      <!-- Customize your theme here. --> 
      <item name="colorPrimary">@color/colorPrimary</item> 
      <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
      <item name="colorAccent">@color/colorAccent</item> 

     </style> 
</resources> 

colors.xml

<resources> 
<color name="colorPrimary">#3F51B5</color> 
    <color name="colorPrimaryDark">#1a237e</color> 
    <color name="transparent">@android:color/transparent</color> 
    <color name="colorAccent">#FF4081</color> 
    <color name="windowBackground">#313131</color> 

</resources> 

вы можете изменить цвета в соответствии с вашими потребностями.

AndroidManifest.xml

<application 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:supportsRtl="true" 
     android:theme="@style/AppTheme"> 

    //your activities 

</application> 

надеюсь, что это помогает ...
