由于某些 GUI 要求,我正在使用EditText&创建基于建议的搜索功能。PopupWindow搜索和建议工作完美,但我无法通过 Dpad浏览搜索EditText和列出项目。PopupWindow

以下是我整个屏幕的布局:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <ImageView

        android:gravity="center"
        android:padding="5dp"
        android:src="@drawable/ic_app_logo" />

    <EditText
        android:id="@+id/team_search_bar"
        android:layout_width="@dimen/home_screen_search_bar_width"

    <TextView
        android:id="@+id/team_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/logo"
        android:layout_marginLeft="@dimen/home_screen_content_margin_left"
        android:layout_marginTop="20dp"
        android:text="@string/home_title"
        android:textColor="@color/white"
        android:textSize="@dimen/home_screen_title" />

    <TextView
        android:id="@+id/team_description"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/team_title"
        android:layout_marginEnd="600dp"

        android:layout_marginStart="25dp"
        android:layout_marginTop="10dp"
        android:maxLines="4"
        android:maxWidth="600dp"
        android:scrollHorizontally="false"
        android:text="@string/short_description"
        android:textColor="@color/team_desciption_color"
        android:textSize="@dimen/home_screen_short_description" />

</RelativeLayout>

<fragment
    android:id="@+id/main_browse_fragment"
    android:name=".ui.HomeFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentBottom="true"
    android:layout_alignTop="@+id/top_baseline"
    android:nextFocusUp="@+id/team_search_bar"
    tools:context=".ui.HomeActivity"
    tools:deviceIds="tv"
    tools:ignore="MergeRootFrame" />

</RelativeLayout>  

BrowseFragment卡中包含一些细节。一切正常,除了我无法浏览EditText和.ListViewPopupWindow

有什么方法可以让我使用 D-pad 进行导航吗???
