我在玩视频(在VideoView
在肖像模式)(全屏幕不是),当我改变
横向模式的视频站。
当我把它改为横向该视频将出现全屏幕上,并会继续打球。
什么建议吗?

所有你需要做的是增加在AndroidManifest.xml活动:
android:configChanges="orientation"
您的视频活动应该是这个样子。
<activity android:name=".VideoPlayerActivity"
android:configChanges="orientation" />
如果你的目标API等级13以上,你必须包括screenSize
,除了价值orientation
所描述的价值在这里 。 您的视频活动应该是这个样子。
<activity android:name=".VideoPlayerActivity"
android:configChanges="orientation|screenSize" />
然后将下面的方法添加到VideoPlayerActivity:
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}
横向全屏视频
AndroidManifext.xml(设置方向)
<activity
android:name=".Video1"
android:screenOrientation="landscape" />
Video1.xml代码:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Video1">
<VideoView
android:id="@+id/videoView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
</VideoView>
Video1.java代码:
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.WindowManager;
import android.widget.MediaController;
import android.widget.VideoView;
public class Video1 extends AppCompatActivity {
private VideoView videoView;
private MediaController mediaController;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video1);
videoView = findViewById(R.id.videoView);
String fullScreen = getIntent().getStringExtra("fullScreenInd");
if("y".equals(fullScreen)){
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
getSupportActionBar().hide();
}
Uri videoUri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.YOUR_VIDEO_NAME);
videoView.setVideoURI(videoUri);
mediaController = new FullScreenMediaController(this);
mediaController.setAnchorView(videoView);
videoView.setMediaController(mediaController);
videoView.start();
}
}
FullScreenMediaControler.java代码:
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.Gravity;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.ImageButton;
import android.widget.MediaController;
public class FullScreenMediaController extends MediaController {
private ImageButton fullScreen;
private String isFullScreen;
public FullScreenMediaController(Context context) {
super(context);
}
@Override
public void setAnchorView(View view) {
super.setAnchorView(view);
//image button for full screen to be added to media controller
fullScreen = new ImageButton (super.getContext());
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.RIGHT;
params.rightMargin = 80;
addView(fullScreen, params);
//fullscreen indicator from intent
isFullScreen = ((Activity)getContext()).getIntent().
getStringExtra("fullScreenInd");
if("y".equals(isFullScreen)){
fullScreen.setImageResource(R.drawable.ic_fullscreen_exit);
}else{
fullScreen.setImageResource(R.drawable.ic_fullscreen);
}
//add listener to image button to handle full screen and exit full screen events
fullScreen.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getContext(),Video1.class);
if("y".equals(isFullScreen)){
intent.putExtra("fullScreenInd", "");
}else{
intent.putExtra("fullScreenInd", "y");
}
((Activity)getContext()).startActivity(intent);
}
});
}
}
除非你指定,配置变化(如屏幕方向,语言,输入设备等的变化)将导致破坏你的当前活动,通过在onPause()的onStop()的正常活动的生命周期过程中去,的onDestroy()作为合适的。 如果活动已经在前台或对用户可见,一旦的onDestroy()被调用该实例,则活动的新实例将被创建,与任何savedInstanceState以前的实例已经从的onSaveInstanceState(束)产生。
到底发生了什么幕后:currnet VideoView活动(横向)被破坏,新的VideoView活动(纵向)已更改创建由于screenOrientation配置和immidiately destoryed(在这里你可以看到屏幕上的影响),在堆栈上一次活动被示出。
尝试处理这个方法,并检查
@Override
protected void onResume() {
mVideoView.resume();
super.onResume();
}
@Override
protected void onPause() {
mVideoView.suspend();
super.onPause();
}
@Override
protected void onDestroy() {
mVideoView.stopPlayback();
super.onDestroy();
}
