Android-在工具栏中显示文件路径

I solved this by using a RecyclerView as @aelimill suggested. This is the custom list item I used:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:gravity="center_vertical"
    android:id="@+id/relativeLayout">

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id="@+id/imageButton"
        android:src="@drawable/ic_keyboard_arrow_right_white_24dp"
        android:background="@null"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignTop="@+id/textView"
        android:layout_alignBottom="@+id/textView" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id="@+id/textView"
        android:background="?android:attr/selectableItemBackgroundBorderless"
        android:clickable="true"
        android:focusable="true"
        android:layout_centerVertical="true"
        android:layout_toRightOf="@+id/imageButton"
        android:layout_toEndOf="@+id/imageButton"
        android:gravity="center"
        android:textSize="16sp"
        android:minWidth="20dp"
        android:textColor="#ffffff"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>

Use selectableItemBackground instead of selectableItemBackgroundBorderless to support pre lollipop devices. (It wont be a circle animation, but a rectangle animation).
