Question

我刚刚更新了build.gradle（Module：app）dependecies，之后在Android Studio上出现了渲染问题。有什么不对，在更新依赖关系之前，everythink正常工作

以下是现在的情况：

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:design:23.0.0'
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.google.android.gms:play-services:7.8.0'
    compile 'com.android.support:support-v4:23.0.0'

    compile 'com.android.support:recyclerview-v7:23.0.0'
}

my_activity.xml

<?xml version="1.0" encoding="utf-8"?>

            android:layout_marginTop="4dp"

                android:layout_height="match_parent"

                <android.support.v7.widget.Toolbar
                    android:id="@+id/appToolbar"
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize"
                    app:layout_collapseMode="pin" />

                <android.support.design.widget.TabLayout
                    style="@style/AppTheme.TabLayout"

            </android.support.design.widget.CollapsingToolbarLayout>
        </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

得到了这个错误：

Rendering Problems Missing styles. Is the correct theme chosen for this layout?      

Use the Theme combo box above the layout to choose a different layout, or fix the theme style references.  

The following classes could not be instantiated:
    - android.support.design.widget.CollapsingToolbarLayout (Open Class, Show Exception, Clear Cache)

Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE
