Question

我正在开发一个应用程序，其中我使用了recyclerview以及工具栏，我的惊喜工具栏重叠了recyclerview，即使我使用了协调器布局，也许我在正确实现它时出错了所以这就是。< / p>

XML

 <android.support.design.widget.CoordinatorLayout
        android:id="@+id/main_content"
        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"
        >

    <!-- AppBarLayout is a wrapper for a Toolbar in order to apply scrolling effects. -->
    <!-- Note that AppBarLayout expects to be the first child nested within a CoordinatorLayout -->

        android:layout_height="wrap_content"

        <!-- Toolbar is the actual app bar with text and the action items -->
        <android.support.v7.widget.Toolbar

        android:layout_marginBottom="5dp"
        android:src="@drawable/ic_search_black_24dp" />
    </android.support.design.widget.CoordinatorLayout>

Answer 1

包含NestedScrollView的{{1}}个人应具有RecyclerView属性。

这会告知app:layout_behavior="@string/appbar_scrolling_view_behavior" CoordinatorLayout需要与应用栏协调一致。

Answer 2

您需要在app:layout_behavior="@string/appbar_scrolling_view_behavior"

中添加android.support.v4.widget.NestedScrollView

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="@+id/main_content"
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:paddingTop="15dp">

    </LinearLayout>
