Android多媒體播放器之視訊播放器

Android視訊播放器

這裡我們大家分享兩種視訊播放的方法：
           

第一種是用MediaPlayer+SeerBar+SurfaceView

MediaPlayer：加載視訊檔案mediaPlayer.setDataSource(this, Uri.parse("file://storage/sdcard/DCIM/Camera/ddbb.mp4"));
SeerBar：顯示目前視訊播放的的位置，快進、後退視訊
SurfaceView：顯示視訊畫面
           

先看效果圖：

因為MediaPlayer是從SD卡拿視訊的，是以要權重限：
           

下面是具體代碼：

public class MainActivity extends AppCompatActivity {

    private SurfaceView sv_main_surface;
    private SeekBar sb_main_seekBar;
    private MediaPlayer mediaPlayer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        }
        setContentView(R.layout.activity_main);
        //擷取SurfaceView
        sv_main_surface = (SurfaceView) findViewById(R.id.sv_main_surface);
        //擷取SeekBar
        sb_main_seekBar = (SeekBar) findViewById(R.id.sb_main_seekBar);
        //進度條滑動事件
        sb_main_seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
            }
            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {
            }
            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
                //擷取seekBar的目前滑動位置
                int sb=sb_main_seekBar.getProgress();
                //快進視訊
                mediaPlayer.seekTo(sb);
            }
        });
    }

    public void startMediaPlayer(View view){
        final ImageView imageView= (ImageView) view;

        //SD卡播放視訊
        if (mediaPlayer==null) {
            mediaPlayer=new MediaPlayer();
            try {
                //設定視訊SD卡路徑
                mediaPlayer.setDataSource(this, Uri.parse("file://storage/sdcard/DCIM/Camera/ddbb.mp4"));
                //準備
                mediaPlayer.prepare();
            } catch (IOException e) {
                e.printStackTrace();
            }


                    imageView.setImageResource(android.R.drawable.ic_media_pause);
                    //将視訊展示到sv_main_surface
                    mediaPlayer.setDisplay(sv_main_surface.getHolder());
                    //進度條最大值
            Log.i("test","DDDDDDDDDDD="+mediaPlayer.getDuration());
                    mediaPlayer.start();
                    sb_main_seekBar.setMax(mediaPlayer.getDuration());
                    new myThread().start();


        }else if (mediaPlayer.isPlaying()) {
            //暫停視訊
            mediaPlayer.pause();
            imageView.setImageResource(android.R.drawable.ic_media_play);
        }else{
            //播放視訊
            mediaPlayer.start();
            imageView.setImageResource(android.R.drawable.ic_media_pause);
        }


    }

    //seekbar
    class myThread extends Thread{
        @Override
        public void run() {
            super.run();
            while(sb_main_seekBar.getProgress()<=sb_main_seekBar.getMax()){
                //擷取視訊目前播放的位置
                int position=mediaPlayer.getCurrentPosition();
                sb_main_seekBar.setProgress(position);

            }
        }
    };
}
           

第二種視訊播放VideoView：

使用VideoView播放視訊就比較簡單了，不像使用MediaPlayer那麼麻煩
還是老規矩先看效果圖：
           

這兩張圖檔看起效果差不多，其實仔細看這一張是沒有進度條的好了廢話不多說，直接看代碼：

public class VideoviewActivity extends AppCompatActivity {

    private VideoView vv_videoview_video;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        }
        setContentView(R.layout.activity_videoview);
        //擷取VideoView
        vv_videoview_video = (VideoView) findViewById(R.id.vv_videoview_video);
        //設定視訊位址
        vv_videoview_video.setVideoPath("file://storage/sdcard/DCIM/Camera/ddbb.mp4");
        //執行個體化媒體控制器
        MediaController mediaController=new MediaController(this);
        mediaController.setMediaPlayer(vv_videoview_video);
        vv_videoview_video.setMediaController(mediaController);
    }
}
