1、基本使用

        private VideoView videoView;        /**         * 本地视频播放         */        videoView.setVideoPath("");        /**         * 网络视频播放         */        videoView.setVideoURI(Uri.parse(""));        /**         * 使用MediaController控制视频播放         */        MediaController controller=new MediaController(this);        /**         * 设置VideoView与MediaConroller类建立关联         */        videoView.setMediaController(controller);        /**         * 设置MediaConroller与VideoView建立关联         */        controller.setMediaPlayer(videoView);

2、设置自定义界面，横竖屏切换，调节音量和亮度

  @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        audioManager=(AudioManager)getSystemService(AUDIO_SERVICE);        /**         * 本地视频播放         */        videoView.setVideoPath("");        videoView.start(); initView();        //播放器事件        setPlayEvent();    }

  private void initView(){        controllayout=(LinearLayout)findViewById(R.id.controllerbar_layour);        videoView=(VideoView) findViewById(R.id.videoView);        pause_img=(ImageView) findViewById(R.id.pause_img);        screen_img=(ImageView) findViewById(R.id.screen_img);        current_text_tv=(TextView)findViewById(R.id.time_current_tv);        time_toatal_tv=(TextView)findViewById(R.id.time_total_tv);        play_seek=(SeekBar)findViewById(R.id.play_seek);        volumm_seek=(SeekBar)findViewById(R.id.volumm_seek);        screen_width=getResources().getDisplayMetrics().widthPixels;        screen_height=getResources().getDisplayMetrics().heightPixels;        videolayout=(RelativeLayout) findViewById(R.id.videolayout);        volume_img=(ImageView)findViewById(R.id.volume_img);        //获取当前设备最大音量        int maxVolume=audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);        //获取当前设备的音量        int streamVolume=audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);        volumm_seek.setMax(maxVolume);        volumm_seek.setProgress(streamVolume);    }

@Override    protected void onPause() {        super.onPause();        UIHandler.removeMessages(UPDATE_UI);    }    @Override    protected void onDestroy() {        super.onDestroy();        UIHandler.removeMessages(UPDATE_UI);    }

    private void setVideoViewScale(int width,int height){        ViewGroup.LayoutParams params= videoView.getLayoutParams();        params.width=width;        params.height=height;        videoView.setLayoutParams(params);        ViewGroup.LayoutParams params1=videolayout.getLayoutParams();        params1.width=width;        params1.height=height;        videolayout.setLayoutParams(params1);    }

       }        textView.setText(str);    }    /**     * 时时更新UI     */    private Handler UIHandler=new Handler(){        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);

               play_seek.setProgress(currentPosition);                UIHandler.sendEmptyMessageDelayed(UPDATE_UI, 500);            }        }    };    private void setPlayEvent(){        /**         * 控制视频的播放和暂停         */        pause_img.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if(videoView.isPlaying()){                    //更改图标                    //暂停                    videoView.pause();
