一切正常，就像流媒体视频一样，但我无法让这个 VideoView 转到 landscape 并在 中显示视频全屏。我试过用谷歌搜索它，但我发现的所有例子目前都不适合我。所以请告诉我如何切换 全屏 。
谢谢。
要全屏播放视频，您必须创建单独的 activity，如下所示。
半屏 activity 是 -
public class HalfScreen extends Activity {
Button fullbtn;
VideoView videoView = null;
final int REQUEST_CODE = 5000;
// "https://www.youtube.com/embed/olsO7UJemhE";
final String videoToPlay = "http://bffmedia.com/bigbunny.mp4";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.half);
videoView = (VideoView) findViewById(R.id.VideoViewhalf);
final ProgressBar progressBar = (ProgressBar) findViewById(R.id.progressBar);
fullbtn = (Button) findViewById(R.id.btnfullScreen);
Uri video = Uri.parse(videoToPlay);
videoView.setVideoURI(video);
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
progressBar.setVisibility(View.GONE);
videoView.requestFocus();
videoView.start();
}
});
fullbtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent videointent = new Intent(HalfScreen.this,
FullScreen.class);
videointent.putExtra("currenttime",
videoView.getCurrentPosition());
videointent.putExtra("Url", videoToPlay);
startActivityForResult(videointent, REQUEST_CODE);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK && requestCode == REQUEST_CODE) {
if (data.hasExtra("currenttime")) {
int result = data.getExtras().getInt("currenttime", 0);
if (result > 0) {
if (null != videoView) {
videoView.start();
videoView.seekTo(result);
ProgressBar progressBar = (ProgressBar) findViewById(R.id.progressBar);
progressBar.setVisibility(View.VISIBLE);
}
}
}
}
}
}
//Now the full screen activity
public class FullScreen extends Activity {
Button btn;
VideoView videoView = null;
int currenttime = 0;
String Url="";
private static ProgressDialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();
if (null != extras) {
currenttime = extras.getInt("currenttime", 0);
Url=extras.getString("Url");
}
setContentView(R.layout.full);
progressDialog = ProgressDialog.show(this, "", "Loading...", true);
videoView = (VideoView) findViewById(R.id.VideoViewfull);
MediaController mediaController = new MediaController(this);
mediaController.setAnchorView(videoView);
Uri video = Uri.parse(Url);
videoView.setMediaController(mediaController);
videoView.setVideoURI(video);
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer arg0) {
progressDialog.dismiss();
videoView.start();
videoView.seekTo(currenttime);
}
});
}
@Override
public void finish() {
Intent data = new Intent();
data.putExtra("currenttime", videoView.getCurrentPosition());
setResult(RESULT_OK, data);
super.finish();
}
}
//To make the video full screen use below layout
full.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ff99cc"
android:orientation="vertical" >
<VideoView
android:id="@+id/VideoViewfull"
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" >
</VideoView>
</RelativeLayout>
我所做的是创建了一个 CustomVideoView，它像这样扩展 VideoView：
public class CustomVideoView extends VideoView {
private int measuredWidth = 0;
private int measuredHeight = 0;
public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
// TODO Auto-generated constructor stub
}
public CustomVideoView(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public CustomVideoView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public void setNewDimension(int width, int height) {
this.measuredHeight = height;
this.measuredWidth = width;
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// TODO Auto-generated method stub
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
setMeasuredDimension(measuredWidth, measuredHeight);
}
}//end class
然后在我的播放器 activity 上，我在全屏按钮的 onclick 上实现了这个：
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
android.widget.RelativeLayout.LayoutParams params = new android.widget.RelativeLayout.LayoutParams(
android.widget.RelativeLayout.LayoutParams.MATCH_PARENT,
android.widget.RelativeLayout.LayoutParams.MATCH_PARENT);
player.setNewDimension(metrics.widthPixels, metrics.heightPixels);
player.getHolder().setFixedSize(metrics.heightPixels,
metrics.widthPixels);
player.setLayoutParams(params);
这样我的问题就解决了。希望它也能解决其他问题。
注意：很抱歉没有给任何人积分，因为我忘记了我在 google 上找到的链接，这些链接让我为自己制定了一个合适的解决方案。
我知道为时已晚，但我只是为其他朋友写的。
只需将此行添加到您的清单 activity 以避免重新加载视频
android:configChanges="orientation|screenSize|keyboardHidden"
