blocks|key|103514|text|好了，看看你的gradle，你在app/build.gradle文件中添加了支持:appcompat依赖吗？也叫appcompat:设计依赖|type|unstyled|depth|inlineStyleRanges|entityRanges|data|103515|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Well, check your gradle , have you added support:appcompat dependency in app/build.gradle file ? also appcompat:design dependency

blocks|key|2853640|text|我解决了这个问题，将gradle插件版本升级到3.0.0-alpha2，并使用gradle包装器gradle-4.0-milestone+1-all.zip。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2853641|我在android+studio的问题跟踪器-+https://issuetracker.google.com/u/1/issues/62251892中记录了这个问题。|offset|length|2853642|entityMap|0|LINK|mutability|MUTABLE|url|https://issuetracker.google.com/u/1/issues/62251892^0|0|O|1F|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

I solved the issue by upgrading the gradle plugin version to 3.0.0-alpha2 and using gradle wrapper gradle-4.0-milestone-1-all.zip.

I logged the issue in android studio issue tracker - <a href="https://issuetracker.google.com/u/1/issues/62251892" rel="nofollow noreferrer">https://issuetracker.google.com/u/1/issues/62251892</a>

blocks|key|2853647|text|我也有这个问题，解决方法如下:将build.gradle+(modle:app)上的appcompat-v7:26.0.0-beta2修改为appcompat-v7:26.0.0-beta1。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2853648|entityMap^0|G|C|U|9|16|P|1Y|P|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

This will working for me. Make sure you add these dependencies:

<pre><code>compile "com.android.support:support-core-utils:26.0.0-beta2"
compile "com.android.support:support-v4:26.0.0-beta2"
compile "com.android.support:support-v13:26.0.0-beta2"

and 

<pre><code>classpath 'com.android.tools.build:gradle:2.3.3'

Dude
I'm also having same issue using Android Studio 3.0, 
I got an solution by just make some changes in style file under the value folder of res. 

Here it is...



<pre><code>&lt;!-- Base application theme. --&gt;
&lt;style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar"&gt;
 &lt;!-- Customize your theme here. --&gt;
 &lt;item name="colorPrimary"&gt;@color/colorPrimary&lt;/item&gt;
 &lt;item name="colorPrimaryDark"&gt;@color/colorPrimaryDark&lt;/item&gt;
 &lt;item name="colorAccent"&gt;@color/colorAccent&lt;/item&gt;
&lt;/style&gt;
</code></pre>



I have added "Base." in parent to make it work properly!

<h1>rendering failed in Android Studio android.support.v7.widget.AppCompatImageView</h1>
Environment I was working on: 
Android Studio 3.0.1
Cause was found to be in <code>app/build.gradle</code> file:
<pre><code>apply plugin: 'com.android.application'

android {
 compileSdkVersion 24 -----&gt; 1
 buildToolsVersion &quot;24.0.0&quot; -----&gt; 2

 defaultConfig {
 applicationId &quot;com.example.some_project&quot;
 minSdkVersion 15
 targetSdkVersion 24 -----&gt; 3
 versionCode 1
 versionName &quot;1.0&quot;
 }
 buildTypes {
 release {
 minifyEnabled false
 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
 }
 }
}

dependencies {
 compile fileTree(dir: 'libs', include: ['*.jar'])
 compile 'com.android.support:appcompat-v7:24.0.0' -----&gt; 4
}
</code></pre>
I changed some of the respective lines to be as follows:
<pre><code>compileSdkVersion 26 &lt;------------ 1
buildToolsVersion &quot;26.0.3&quot; &lt;------------ 2

targetSdkVersion 26 &lt;------------ 3

compile 'com.android.support:appcompat-v7:26.1.0' &lt;---- 4
</code></pre>
And I didn't need to change anything in the <code>styles.xml</code> file. Most of the answers above had suggested to change following line:
<pre><code>&lt;style name=&quot;AppTheme&quot; parent=&quot;Theme.AppCompat.Light&quot;&gt;
</code></pre>
into following:
<pre><code>&lt;style name=&quot;AppTheme&quot; parent=&quot;Base.Theme.AppCompat.Light&quot;&gt;
</code></pre>
But I didn't want to do it. It seems like that, Google Android has moved the <code>Theme(s)</code> API from <code>Base</code> package to a more root package, when they have upgraded the API.

I just started learning Kotlin for android development and started an empty project and added an activity. I have added the required gradle dependencies as said in Kotlin docs. By default the xml file of MainActivity contains only a TextView. But when I try to preview the xml in Layout Editor it shows a "Render Error" 

<pre><code>Render problem

Failed to load AppCompat ActionBar with unknown error.
</code></pre>

Also I'm getting this

<pre><code>The following classes could not be instantiated:
- android.support.v7.widget.AppCompatImageView (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.ActionBarContainer (Open Class, Show Exception, Clear Cache)

- android.support.v7.widget.ActionBarOverlayLayout (Open Class, Show Exception, Clear Cache)


Exception Details java.lang.ClassNotFoundException: android.support.v4.view.TintableBackgroundView
</code></pre>

I have tried rebuilding the project and refreshing layout manually. But nothing seems to work. 

So what do I do? I'm using Android Studio 3.0 Canary 2 with Kotlin

EDITED:

I have made some progress. I have found that none of my AppCompat Themes are working.
