【Android运行时错误】Error inflating class CollapsingToolbarLayout

近期在调试代码时，突然遇到这样的一个错误，Error inflating class CollapsingToolbarLayout，这里记录一下。

刚开始并不知道问题所在，以为是自己的代码出问题了，因为毕竟报的错误是代码中的

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.itbird.test/com.itbird.test.ui.activity.RandomActivity}: android.view.InflateException: Binary XML file line #22: Error inflating class android.support.design.widget.CollapsingToolbarLayout  at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2325)  at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2387)  at android.app.ActivityThread.access$800(ActivityThread.java:151)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1303)  at android.os.Handler.dispatchMessage(Handler.java:102)  at android.os.Looper.loop(Looper.java:135)  at android.app.ActivityThread.main(ActivityThread.java:5254)  at java.lang.reflect.Method.invoke(Native Method)  at java.lang.reflect.Method.invoke(Method.java:372)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:903)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698)Caused by: android.view.InflateException: Binary XML file line #22: Error inflating class android.support.design.widget.CollapsingToolbarLayout  at android.view.LayoutInflater.createView(LayoutInflater.java:633)  at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:743)  at android.view.LayoutInflater.rInflate(LayoutInflater.java:806)  at android.view.LayoutInflater.rInflate(LayoutInflater.java:809)  at android.view.LayoutInflater.rInflate(LayoutInflater.java:809)  at android.view.LayoutInflater.inflate(LayoutInflater.java:504)  at android.view.LayoutInflater.inflate(LayoutInflater.java:414)  at android.view.LayoutInflater.inflate(LayoutInflater.java:365)  at android.support.v7.app.AppCompatDelegateImplV7.setContentView(AppCompatDelegateImplV7.java:276)  at android.support.v7.app.AppCompatActivity.setContentView(AppCompatActivity.java:136)  at com.itbird.test.ui.activity.RefreshableActivity.onCreate(RefreshableActivity.java:31)  at android.app.Activity.performCreate(Activity.java:5990)  at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1106)  at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2278)  at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2387)   at android.app.ActivityThread.access$800(ActivityThread.java:151)   at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1303)   at android.os.Handler.dispatchMessage(Handler.java:102)   at android.os.Looper.loop(Looper.java:135)   at android.app.ActivityThread.main(ActivityThread.java:5254)   at java.lang.reflect.Method.invoke(Native Method)   at java.lang.reflect.Method.invoke(Method.java:372)   at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:903)   at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698) Caused by: java.lang.reflect.InvocationTargetException  at java.lang.reflect.Constructor.newInstance(Native Method)  at java.lang.reflect.Constructor.newInstance(Constructor.java:288)  at android.view.LayoutInflater.createView(LayoutInflater.java:607)  at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:743)   at android.view.LayoutInflater.rInflate(LayoutInflater.java:806)   at android.view.LayoutInflater.rInflate(LayoutInflater.java:809)   at android.view.LayoutInflater.rInflate(LayoutInflater.java:809)   at android.view.LayoutInflater.inflate(LayoutInflater.java:504)   at android.view.LayoutInflater.inflate(LayoutInflater.java:414)   at android.view.LayoutInflater.inflate(LayoutInflater.java:365)   at android.support.v7.app.AppCompatDelegateImplV7.setContentView(AppCompatDelegateImplV7.java:276)   at android.support.v7.app.AppCompatActivity.setContentView(AppCompatActivity.java:136)   at com.itbird.test.ui.activity.RefreshableActivity.onCreate(RefreshableActivity.java:31)   at android.app.Activity.performCreate(Activity.java:5990)   at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1106)   at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2278)   at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2387)   at android.app.ActivityThread.access$800(ActivityThread.java:151)   at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1303)   at android.os.Handler.dispatchMessage(Handler.java:102)   at android.os.Looper.loop(Looper.java:135)   at android.app.ActivityThread.main(ActivityThread.java:5254)   at java.lang.reflect.Method.invoke(Native Method)   at java.lang.reflect.Method.invoke(Method.java:372)   at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:903)   at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698) Caused by: java.lang.NoSuchMethodError: No static method setLayoutDirection(Landroid/graphics/drawable/Drawable;I)V in class Landroid/support/v4/graphics/drawable/DrawableCompat;

自然而然，我就去查找自己的xml文件，到底有什么错误了

        <android.support.design.widget.CollapsingToolbarLayout            android:id="@+id/collapsing_toolbar"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:clickable="true"            app:contentScrim="@color/blue"            app:statusBarScrim="@color/blue_dark"            app:layout_scrollFlags="scroll|exitUntilCollapsed|snap"            >         //...省略        </android.support.design.widget.CollapsingToolbarLayout>

看着xml代码很正常，那么我们还是返回问题本身，错误日志里面是说CollapsingToolbarLayout控件解析异常，那么是否是android.support包导入有问题？
最终，尝试在 gradle文件中，添加v4的支持，运行正常了。

compile ('com.android.support:support-v4:23.4.0'){    force = true;}
