为什么从约束布局1.0.2切换到1.1.3会破坏我的自定义工具栏？

我们有一个Android应用程序，其中一些活动共享一个工具栏。一切运行良好，直到（根据Android Studio的建议）我将build.gradle文件从constraint-layout：1.0.2切换到1.1.3。现在，工具栏覆盖了整个可见屏幕。我不确定为什么会这样或如何解决。我当前的解决方法是回到1.0.2。

关于这种情况为什么发生以及如何解决的任何想法？

这是build.gradle依赖项：

dependencies {
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:support-v4:26.1.0'

    annotationProcessor project(':annotations')
    implementation project(':falcon') // Supports screenshots

    testImplementation 'junit:junit:4.12'
    // We use Mockito because it doesn't need extra code to mock final methods and classes.
    // JMock could work, if DexOpener worked (like JDave-Unfinalizer, but for DEX files), but
    // I was unable to make it work.  Hence I switched to Mockito, which is the favorite among Android
    // Developers (SMM)

//    testImplementation 'org.mockito:mockito-inline:2.13.0'
    testImplementation files('../../../../lib/jmock-2.8.4/hamcrest-core-1.3.jar')
    testImplementation files('../../../../lib/jmock-2.8.4/hamcrest-library-1.3.jar')
    testImplementation files('../../../../nb/ORCCommon/dist/ORCCommon-test.jar')
    testImplementation files('../../../../nb/CommonLibrary/dist/CommonLibrary-test.jar')
    androidTestImplementation 'com.android.support.test:rules:1.0.1'
    androidTestImplementation('com.android.support.test.espresso:espresso-core:3.0.1', {
        exclude group: 'com.google.code.findbugs' // We already have findbugs
    })
}

这是工具栏：
