.design.widget.CollapsingToolbarLayout{41e561a0 V.ED.... ......I. 0,0-720,400 #7f0c0068 app:id/collapsing_toolbar} during second layout pass: posting in next frame

我的主要問題是，build.gradle配置中使用的：

    compile 'com.android.support:design:22.2.0'

調整為：

    compile 'com.android.support:design:22.2.1'

問題解決正常顯示……….
