我尝试了此操作，但仍然没有填充视频视图.

I tried this but I still didn't fill video view.

这是我的布局代码:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    android:background="@drawable/search_gren_screen">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/go_back"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:layout_weight="1"
            android:onClick="onclick"
            android:text="Try again" />

        <Button
            android:id="@+id/back_to_pick_song"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:text="Select another song" 
            android:onClick="onclick" />

        <Button
            android:id="@+id/btn_continue"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_weight="1"
            android:onClick="onclick"
            android:text="Amazing, continue!" />
    </LinearLayout>

    <FrameLayout 
      android:layout_width="fill_parent"
      android:layout_height="fill_parent">
    <VideoView 
        android:id="@+id/videoView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:layout_gravity="center" />
    </FrameLayout>
</LinearLayout>

这是我声明的布局的预览:

Here you have a preview of my declared layout:

但是，设备上的结果却不同:

However, the result on the device is different:

推荐答案

尝试使外部布局成为相对布局，然后将VideoView放在其中.

Try to make your outer layout a relative layout and put the VideoView inside that.

类似的东西:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/trim_container"
     android:layout_width="match_parent"
     android:layout_height="match_parent" >

     <LinearLayout
          android:id="@+id/buttonContainer"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:orientation="horizontal" >

     <Button
          android:id="@+id/go_back"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_gravity="center"  
          android:layout_weight="1"
          android:onClick="onclick"
          android:text="Try again" />

     <Button
          android:id="@+id/back_to_pick_song"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_weight="1"
          android:text="Select another song" 
          android:onClick="onclick" />

    <Button
          android:id="@+id/btn_continue"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_gravity="center"
          android:layout_weight="1"
          android:onClick="onclick"
          android:text="Amazing, continue!" />
  </LinearLayout>

  <VideoView
     android:id="@+id/VideoView"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:layout_alignParentLeft="true"
     android:layout_alignParentRight="true"
     android:layout_alignParentBottom="true"
     android:layout_below="@id/buttonContainer"/>
</RelativeLayout>
