Question

我想在我的应用中实现一个CollapsingToolbarLayout（我希望它像Play商店的视差效果）

我在stackOverflow本身以及Android的开发者网站上看到了很多问题。

问题是，我总是在IDE（Android Studio）中出现错误

The following classes could not be instantiated: - android.support.design.widget.CollapsingToolbarLayout

如果我在手机上运行该活动，则该应用程序崩溃并显示错误

Caused by: java.lang.NoSuchMethodError: No static method setLayoutDirection(Landroid/graphics/drawable/Drawable;I)V in class Landroid/support/v4/graphics/drawable/DrawableCompat; or its super classes (declaration of 'android.support.v4.graphics.drawable.DrawableCompat' appears in /data/data/com.hemal.eventhub2/files/instant-run/dex/slice-com.android.support-support-v4-24.0.0_b8d850cc5f06d621d9211f2cbc20e32dfc36ae82-classes.dex)
                                                                       at android.support.design.widget.CollapsingToolbarLayout.setStatusBarScrim(CollapsingToolbarLayout.java:663)

我很确定这与冲突的导入或依赖关系有关。

我的app模块gradle脚本是

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.hemal.eventhub2"
        minSdkVersion 19
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.android.volley:volley:1.0.0'
    compile 'com.android.support:design:23.2.1'
    compile 'com.google.android.gms:play-services-auth:9.6.1'
    compile 'com.google.firebase:firebase-core:9.6.1'
    compile 'com.google.firebase:firebase-messaging:9.6.1'
}

apply plugin: 'com.google.gms.google-services'

以下是我应用的MainAcitivity中的一些导入

import android.support.design.widget.NavigationView;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.GravityCompat;
import android.support.v4.view.ViewPager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

上述导入或依赖项是否存在冲突导致问题。我还从1.5.1将我的Android Studio更新到2.2.1，希望它可以解决问题

您能否指导我删除，保存或下载哪些SDK，导入和依赖项以使CollapingToolbarLayout正常工作。

无法实例化CollapsingToolbarLayout
