android - android应用程序中的VideoView全屏

Question

我的应用程序中有一个视频视图。代码是这样的。

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

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/opsbuds"
    android:orientation="vertical">

    <TextView
        android:id="@+id/adtxt1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"></TextView>

    <VideoView
        android:id="@+id/videoView11"
        android:layout_width="300dip"
        android:layout_height="250dip"
        android:layout_marginLeft="30dip"></VideoView>

    <LinearLayout
        android:id="@+id/llv11"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"></LinearLayout>

    <Button
        android:id="@+id/button1211"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:layout_marginTop="10dp"
        android:background="@drawable/button"
        android:text=" Continue "
        android:textColor="#800080"
        android:textSize="20dp"
        android:textStyle="bold"></Button>
</LinearLayout>
</ScrollView>

xml 文件中提到了视频视图宽度和高度。我想要的是，一旦我按下一个按钮，videoview 应该全屏显示，一旦我按下返回按钮，videoview 应该回到它提到的大小。请帮忙？

我必须让我的 VideoView 位于 RelativeLayout 中才能使选择的答案起作用。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    
    <VideoView android:id="@+id/videoViewRelative"
         android:layout_alignParentTop="true"
         android:layout_alignParentBottom="true"
         android:layout_alignParentLeft="true"
         android:layout_alignParentRight="true"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent">
    </VideoView>
    
</RelativeLayout>

如此处给出：Android - 如何拉伸视频以填充 VideoView 区域在屏幕尺寸之间切换就像更改所选答案中给出的布局参数一样简单。

这样设置全屏，

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
params.width = metrics.widthPixels;
params.height = metrics.heightPixels;
params.leftMargin = 0;
videoView.setLayoutParams(params);

并以这种方式恢复原始大小。

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
params.width = (int)(300*metrics.density);
params.height = (int)(250*metrics.density);
params.leftMargin = 30;
videoView.setLayoutParams(params);

我已经这样做了：

检查这些参考屏幕截图。

添加类FullScreenVideoView.java：

import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

public class FullScreenVideoView extends VideoView {
    public FullScreenVideoView(Context context) {
        super(context);
    }

    public FullScreenVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public FullScreenVideoView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        setMeasuredDimension(widthMeasureSpec, heightMeasureSpec);
    }
}

如何与xml绑定：

<FrameLayout
   android:id="@+id/secondMedia"
   android:layout_width="match_parent"
   android:layout_height="match_parent">

     <com.my.package.customview.FullScreenVideoView
           android:layout_width="match_parent"
           android:layout_height="match_parent" 
           android:id="@+id/fullScreenVideoView"/>

</FrameLayout>

希望这会帮助你。

第一种方法

当您想为该活动全屏打开视频时，您必须在清单中设置主题属性。设置这个值是

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

在此处以编程方式更改主题

第二种方法

创建另一个 fullscreen.xml 如下所示并setContentView(R.layout.fullscreen)单击按钮

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

    <VideoView android:id="@+id/myvideoview"
        android:layout_width="fill_parent"
        android:layout_alignParentRight="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:layout_height="fill_parent">
    </VideoView>

</RelativeLayout>

在按钮上单击开始native video player，它将在以下位置打开full screen：

Intent intent = new Intent(Intent.ACTION_VIEW );
intent.setDataAndType(Uri.parse(path), "video/*");
startActivity(intent);

下面的代码有效。

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

在调用 videoView.start() 之前添加此代码。在大多数情况下，视频活动以全屏模式运行。但是，如果标题栏仍然显示，则将清单中的主题更改为此。

    android:theme="@style/Theme.AppCompat.NoActionBar">

您可以通过创建两个单独的活动来实现它。假设第一个活动是 halfScreen 活动。在此活动中，您的视频视图尺寸较小。点击全屏视频按钮启动另一个活动“全屏活动”。在第二个活动中，视频视图应该与父布局匹配。您还可以从半屏暂停的位置开始全屏播放视频。在我的代码中，我已经实现了这一点。您也可以在半屏上恢复视频全屏活动的后按。这对我有用。希望它也对你有用。

我通过切换到横向并将布局参数设置为MATCH_PARENT. 就在切换到全屏模式之前，我们需要将当前的方向模式和VideoView参数存储在相应defaultScreenOrientationMode的defaultVideoViewParams变量中。这样我们就可以在退出视频全屏模式时使用它们。因此，当您想以全屏模式打开视频时，请使用makeVideoFullScreen()方法，退出 - exitVideoFullScreen()。

请注意，我用于RelativeLayoutmy VideoView，在您的情况下，它可以是另一种布局类型。

private RelativeLayout.LayoutParams defaultVideoViewParams;
private int defaultScreenOrientationMode;

// play video in fullscreen mode
private void makeVideoFullScreen() {

    defaultScreenOrientationMode = getResources().getConfiguration().orientation;
    defaultVideoViewParams = (LayoutParams) videoView.getLayoutParams();

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

    videoView.postDelayed(new Runnable() {

        @Override
        public void run() {
            RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.MATCH_PARENT,
                    RelativeLayout.LayoutParams.MATCH_PARENT);

            videoView.setLayoutParams(params);
            videoView.layout(10, 10, 10, 10);
        }
    }, 700);
}


// close fullscreen mode
private void exitVideoFullScreen() {
    setRequestedOrientation(defaultScreenOrientationMode);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);

    videoView.postDelayed(new Runnable() {

        @Override
        public void run() {
            videoView.setLayoutParams(defaultVideoViewParams);
            videoView.layout(10, 10, 10, 10);
        }
    }, 700);
}

无论您是想保持视频的纵横比还是拉伸它以填充其父区域，使用正确的布局管理器都可以完成工作。

保持纵横比：

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">

<VideoView
  android:id="@+id/videoView"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:layout_gravity="center"/>

</LinearLayout>

！！！要填写该字段：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <VideoView android:id="@+id/videoViewRelative"
         android:layout_alignParentTop="true"
         android:layout_alignParentBottom="true"
         android:layout_alignParentLeft="true"
         android:layout_alignParentRight="true"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent">
    </VideoView>

</RelativeLayout>
