我想成为AppBarLayout

中心页面的进度栏

如何将条形标题和后退按钮应用于右侧？

Answer 2

 /**Make a change in your listview**/

   ListView Interference with AppBarLayout:


  <ListView 
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:id="@+id/listView"
    android:layout_below="@+id/toolbar"
    android:layout_width="fill_parent"
    android:layout_height="match_parent" />


    App bar Title and back button to Right: 

    Just add below line inside application tag in AndroidManifestFile

    android:supportsRtl="true"

Answer 3

    For putting list below app bar you need to update listview layout with below app bar.
    Here is the updated code.

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/activity_category"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context="com.sokhanak.CategoryActivity"
        >
        <android.support.design.widget.AppBarLayout
            android:id="@+id/appBarLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="56dp"
                android:background="?attr/colorPrimary"
                />

        </android.support.design.widget.AppBarLayout>

        <android.support.v4.widget.ContentLoadingProgressBar
            android:id="@+id/progress"
            style="?android:attr/progressBarStyleLarge"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:visibility="visible" />

        <ListView app:layout_behavior="@string/appbar_scrolling_view_behavior"
            android:id="@+id/listView"
            android:layout_below="@+id/appBarLayout"
            android:layout_width="fill_parent"
            android:layout_height="match_parent" />

    </RelativeLayout>
