我在片段中有这个xml代码:

<CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"                              xmlns:app="http://schemas.android.com/apk/res-auto"                         android:layout_width="match_parent"                    android:layout_height="match_parent"                       android:id="@+id/coordinatorLayout"                      android:fitsSystemWindows="true">
     <android.support.design.widget.AppBarLayout
            android:id="@+id/appBarLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/AppTheme"
            app:elevation="0dp">
     <android.support.design.widget.CollapsingToolbarLayout
                android:layout_width="match_parent"
                android:layout_height="300dp"
                app:layout_scrollFlags="scroll"
                android:id="@+id/collapsingToolbarLayout"
                app:statusBarScrim="@color/bestColor">
    <LinearLayout></LinearLayout> <!--this elements hide then appbar is collapsed-->
            </android.support.design.widget.CollapsingToolbarLayout>
    <LinearLayout>
    <ImageButton>
     android:id="@+id/profile_header_trophies"
    </ImageButton><!-- this elements like a tab,visible if appbar collapsed-->
    </LinearLayout> 
        </android.support.design.widget.AppBarLayout>

<android.support.v7.widget.RecyclerView
    android:id="@+id/profile_recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
    </android.support.design.widget.CoordinatorLayout>

在项目集上的Java类ClickListener:

@OnClick(R.id.profile_header_trophies)
    public void profile_header_trophies_clicked() {
        if (myProfile != null) {
            appBarLayout.setExpanded(false, false);
            if (myProfile.getBests().size() == 0) {
                profile_recyclerView.smoothScrollToPosition(3);
            } else {
                profile_recyclerView.smoothScrollToPosition(2 + 20);
                }
            }

当我点击ImageButton时,我的RecyclerView …

我有Android Studio的问题.将AS更新为2.2后,需要很长时间(约30分钟)来处理,表明它是"构建符号..."项目相当大并且包含NDK组件.

使用gradle构建非常快:

BUILD SUCCESSFUL
time: 12.089 secs

我的gradle_wrapper设置:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
android.useDeprecatedNdk=true
org.gradle.daemon=true
org.gradle.parallel=true
#android.dexOptions.preDexLibraries=true
#android.enableBuildCache=true
org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=1024m-
HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

Android Studio有什么问题？我怎样才能加快速度呢？
