android使用video开发简单的视频播放！

来源：互联网发布：阿里云域名管理平台编辑：程序博客网时间：2024/05/18 23:53

由于做资讯类的app，所以涉及到的与h5交互的情况比较多。。。由于项目以前用的是优酷的视频外链。app可以直接用webview 来播放，优酷那边已经做过处理。所以webview那儿可以直接播放。但是现在视屏都上传自己服务器，资讯视屏也用h5原生的。导致app端无法全屏播放视频。网上也有很多方法来解决不是全屏问题，但是曲线救国，有点。。。不予评论。。。

于是乎，决定自己写个简易播放器来全屏播放，一般有三种方式，1。直接用系统的播放器。2.用videoview+mediacontroller 来播放。3.用sufaceview+mediacontroller

由于需要纪录播放进度。所以第一种直接弃用，开发时间有限，所以就决定用第二种。第三种方法适合定制性比较高。功能比较齐全的。但是相对复杂的，我也尝试过

只是做了简单的播放处理。关于第三种，网上有的博客忘记写了，就是 media 发起异步准备的时候，一定要在onPrepared准备的方法里 start一下，否则无法播放。

在此其他的不做过多的叙述，视屏链接如何获取也不予详细说明。网上有很多种。我的大致思路就是与h5开发人员约定一个超链接。我用webview 的方法截取超

链接。来解析获取url。

接下来，请欣赏核心代码简易视屏播放器。大神请绕道。思路是这样的，（因为22版本sdk进度条特别的。。那啥。23版本的还阔以，但是项目的 build版本22 没办法，所以决定，设置控制器后，隐藏掉它自己的显示界面，自定义自己的控制器，加监听。加功能）

布局文件很简单。

简易布局

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.myapplication.MainActivity">    <com.example.myapplication.CustomVideoView        android:id="@+id/vv"        android:layout_width="match_parent"        android:layout_height="match_parent" />    <LinearLayout        android:id="@+id/video_title_name"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentTop="true"        android:layout_centerHorizontal="true"        android:gravity="center"        android:orientation="horizontal"        android:padding="5dp">        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_margin="5dp"            android:text="back"            android:textColor="#666" />        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_margin="5dp"            android:layout_weight="1"            android:text="这是视屏的名称"            android:textColor="#666" />        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_margin="5dp"            android:text="下载"            android:textColor="#666" />    </LinearLayout>    <LinearLayout        android:id="@+id/video_ll"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:orientation="horizontal">        <TextView            android:id="@+id/play"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_gravity="center"            android:layout_margin="10dp"            android:gravity="center"            android:text="暂停"            android:textColor="#eee"            android:textSize="16sp" />        <TextView            android:id="@+id/now_time"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="00:00" />        <SeekBar            android:id="@+id/video_seek_bar"            android:layout_width="wrap_content"            android:layout_height="20dp"            android:layout_marginBottom="20dp"            android:layout_weight="1"            android:maxHeight="10dp"            android:minHeight="10dp" />        <TextView            android:id="@+id/total_time"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="00:00" />    </LinearLayout></RelativeLayout>

下面是java核心代码。超级简单。。

public class MainActivity extends Activity implements View.OnClickListener, SeekBar.OnSeekBarChangeListener, MediaPlayer.OnCompletionListener {    CustomVideoView videoView;    Timer timer = new Timer();

       WindowManager.LayoutParams params = window.getAttributes();        params.systemUiVisibility = View.SYSTEM_UI_FLAG_LOW_PROFILE;        window.setAttributes(params);        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initDatas();        initViews();    }    private void initViews() {        videoView = (CustomVideoView) findViewById(R.id.vv);        videoView.setVideoURI(uri);        seekBar = (SeekBar) this.findViewById(R.id.video_seek_bar);        video_title_name = (LinearLayout) this.findViewById(R.id.video_title_name);        video_ll = (LinearLayout) this.findViewById(R.id.video_ll);

               seekBar.setProgress(mp.getCurrentPosition());            }        });        videoView.setOnCompletionListener(this);        seekBar.setOnSeekBarChangeListener(this);        timer.schedule(new TimerTask() {            @Override            public void run() {                handler.sendEmptyMessage(isPlaying);            }        }, 300, 300);        videoView.requestFocus();    }    private void initDatas() {        uri = Uri.parse("http://iplaymtgtest.oss-cn-beijing.aliyuncs.com/video/2016/08/29/b3592f52-bd2f-462b-99f6-c32bdc593493.mp4");    }    public static int nowNumber = 0;    public static final int isPlaying = 1;    private Handler handler = new Handler() {        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            switch (msg.what) {                case isPlaying:                    if (videoView.isPlaying()) {                        nowNumber = videoView.getCurrentPosition() / 1000;                        if (nowNumber > 0 && nowNumber < 60) {                            now_time.setText("00:" + getTimeS2(nowNumber));                        } else if (nowNumber >= 60) {                            now_time.setText(getTimeS2(nowNumber));                        }                        seekBar.setProgress(videoView.getCurrentPosition());

       videoView.pause();    }    @Override    public void onClick(View v) {        switch (v.getId()) {            case R.id.vv:                break;            case R.id.play:                if (play.getText().toString().equals("暂停")) {                    play.setText("播放");                    videoView.pause();                } else {                    play.setText("暂停");                    videoView.start();                }                break;        }    }    @Override    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {    }    @Override    public void onStartTrackingTouch(SeekBar seekBar) {    }    @Override    public void onStopTrackingTouch(SeekBar seekBar) {        videoView.seekTo(seekBar.getProgress());    }    @Override    public void onCompletion(MediaPlayer mp) {    }    Date d = new Date();    public String getTimeS2(long time) {        SimpleDateFormat sdf1;        if (3600000 < (time * 1000)) {            sdf1 = new SimpleDateFormat("HH:mm:ss");        } else if (60000 <= (time * 1000)) {            sdf1 = new SimpleDateFormat("mm:ss");        } else {            sdf1 = new SimpleDateFormat("ss");        }        d.setTime(time * 1000);        return sdf1.format(d);    }}

哦，对了。最后别忘记在 manifest 里注册 activity 为横屏

android:screenOrientation="sensorLandscape"

一个简易的视频播放器完成。。。

补充：

public class CustomVideoView extends VideoView {    public static int mVideoWidth;    public static int mVideoHeight;    private Context context;    public CustomVideoView(Context context) {        super(context);        this.context = context;//        mGestureDetector = new GestureDetector(context, new LearnGestureListener());        // TODO Auto-generated constructor stub    }    public CustomVideoView(Context context, AttributeSet attrs) {        super(context, attrs);//        mGestureDetector = new GestureDetector(context, new LearnGestureListener());        // TODO Auto-generated constructor stub    }    public CustomVideoView(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);//        mGestureDetector = new GestureDetector(context, new LearnGestureListener());        // TODO Auto-generated constructor stub    }    @Override    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        // TODO Auto-generated method stub        // Log.i("@@@@", "onMeasure");        //下面的代码是让视频的播放的长宽是根据你设置的参数来决定        int width = getDefaultSize(mVideoWidth, widthMeasureSpec);        int height = getDefaultSize(mVideoHeight, heightMeasureSpec);        setMeasuredDimension(width, height);    }    GestureDetector mGesture;    @Override    public boolean onTouchEvent(MotionEvent e) {        if (mGesture == null) {            mGesture = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {                @Override                public boolean onDown(MotionEvent e) {                    return true;                }                @Override                public void onLongPress(MotionEvent e) {                    super.onLongPress(e);                }                @Override                public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {                    return super.onScroll(e1, e2, distanceX, distanceY);                }            });            mGesture.setOnDoubleTapListener(new GestureDetector.OnDoubleTapListener() {                @Override                public boolean onSingleTapConfirmed(MotionEvent e) {                    return true;                }                @Override                public boolean onDoubleTap(MotionEvent e) {                    return true;                }                @Override                public boolean onDoubleTapEvent(MotionEvent e) {                    return false;                }            });        }        GestureDetector mGestureDetector;////        private class LearnGestureListener extends GestureDetector.SimpleOnGestureListener {//            @Override//            public boolean onSingleTapUp(MotionEvent ev) {//                Log.d("onSingleTapUp", ev.toString());//                return true;//            }////            @Override//            public boolean onDown(MotionEvent e) {//                return true;//            }//        }        return super.onTouchEvent(e);    }}
