我有一个CollapsingToolbarLayout它在展开状态下显示后退按钮,但没有显示在折叠状态.

我试过setNavigationIcon()了,Toolbar但它设置了扩展状态.

这是布局

<android.support.design.widget.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:fitsSystemWindows="true">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="250dp"
    android:fitsSystemWindows="true">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/user_collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        app:contentScrim="@color/colorAccent"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            android:scaleType="centerCrop"
            android:src="@drawable/tbt_logo"
            app:layout_collapseMode="parallax" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/user_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?android:attr/actionBarSize"
            app:titleTextColor="@android:color/white"/>
    </android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <include layout="@layout/pen_point_item_layout" />
        <include layout="@layout/pen_point_item_layout" />
    </LinearLayout>
</android.support.v4.widget.NestedScrollView>

Java的:

toolbar = (Toolbar) findViewById(R.id.user_toolbar);
    toolbar.setNavigationIcon(R.drawable.ic_back);
    setSupportActionBar(toolbar);

    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowTitleEnabled(true);
    collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.user_collapsing_toolbar);
    collapsingToolbar.setTitle("Profile");
    collapsingToolbar.setCollapsedTitleTextColor(Color.WHITE);
    collapsingToolbar.setExpandedTitleColor(Color.WHITE);

我该怎么办？

我有一个由 NuxtJS 配置的 Vue 应用程序。我有以下模板和工作方法，应在单击按钮时调用。但他们没有被召唤。

<template>
    <button class="btn google-login" id="google-login" @click.native="googleLogin">
      <img src="~assets/google-icon.svg" alt />
      Login with Google
    </button>
</template>

<script>
import firebase from "firebase";
export default {
  data() {
    return {
      showPassword: false,
      checkbox1: false
    };
  },
  mounted: function() {
    console.log(firebase.SDK_VERSION);
  },
  methods: {
    googleLogin: function(event) {
      console.log('Reached inside the function');


      let googleProvider = new firebase.auth.GoogleAuthProvider();
      googleProvider.addScope(
        "https://www.googleapis.com/auth/contacts.readonly"
      );
      firebase.auth().useDeviceLanguage();
      console.log(googleProvider);
    }
  }
};
</script>

我有methods对象内部的方法。我曾尝试多种解决方案v-on:click，@click，@click.prevent但没有似乎工作

我在 CollapsableToolbar 内的 NestedScrollView 中有 View Pager。但是 ViewPager 片段的内容隐藏在 AppBarLayout 后面。然而，Viewpager 是完全可滚动的。

如何解决这个问题？
