I had to make my VideoView sit in a RelativeLayout in order to make the chosen answer work.

我必须让我的 VideoView 坐在一个 RelativeLayout 中才能使所选的答案起作用。

<?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>

As given here: Android - How to stretch video to fill VideoView areaToggling between screen sizes would be as simple as changing the layout parameters as given in the chosen answer.

Set full screen this way,

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);

And back to original size, this way.

并回到原来的大小，这样。

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);

Add class FullScreenVideoView.java:

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);

First Method

第一种方法

when you want to open a video in full screen for that Activity you have to set the theme attribute in the Manifest. set this value that is

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"

change theme programmatically here

在此处以编程方式更改主题

Second Method

第二种方法

create another fullscreen.xml like below and setContentView(R.layout.fullscreen)on click of the button

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

<?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_alignParentRight="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:layout_height="fill_parent">

On Button click start the native video playerwhich will open in full screen:

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

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

I achieved it by switching to landscape orientation and setting layout params to MATCH_PARENT. Just before switching to fullscreen mode, we need to store current orientation mode and VideoViewparams indefaultScreenOrientationModeand defaultVideoViewParamsvariables correspondingly. So that we can use them when we exit from video fullscreen mode. Thus, when you want to open video in fullscreen mode, use makeVideoFullScreen()method, to exit - exitVideoFullScreen().

我通过切换到横向并将布局参数设置为MATCH_PARENT. 在切换到全屏模式之前，我们需要相应地存储当前的方向模式和VideoView参数defaultScreenOrientationMode和defaultVideoViewParams变量。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()。

Please, note I used RelativeLayoutfor my VideoView, in your case it can be another layout type.

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);
}

回答by Chandra Sharma

you can achieve it by creating two separate activity. Suppose first activity is halfScreen activity. In this activity your video view having small size. On button click of full screen video start another activity 'fullScreen activity'. In second activity the video view should be match parent to the parent layout.you can also start video in full screen from where it is paused in half screen.In my code i have implemented that.Also you can resume the video in half screen on the back press of fullscreen activity. This is work for me.Hope it will work for you also.

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。单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。你也可以从半屏暂停的地方开始全屏视频。在我的代码中，我已经实现了。此外，你可以在半屏上恢复视频全屏活动的背面按下。这对我有用。希望它也对你有用。

回答by K. Rea

whether you want to keep the aspect ratio of a video or stretch it to fill its parent area, using the right layout manager can get the job done.

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

Keep the aspect ratio :

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>

!!! To fill in the field:

！！！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>

回答by saketha yellanki

The below code worked.

下面的代码有效。

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

Add this code before calling videoView.start(). With this the video activity runs in full screen mode in most of the cases. But if the title bar is still displayed then change your theme in your manifest to this.

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">
