视屏播放主要使用VideoView来实现。他将视屏的显示和控制集一身，使用它可以做一个简单的视频播放器。
File file = new File(Environment.getExternalStorageDirectory(), path); videoView.setVideoPath(file.getPath()); // 指定视频文件的路径 videoView.start(); // 开始播放 videoView.pause(); // 暂停播放 videoView.resume(); // 重新播放完整代码：
//视频播放 public class MainActivity extends AppCompatActivity { private VideoView videoView; private Button play; private Button pause; private Button replay; /** * 设置view播放控制条 */ private MediaController mediaController; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); initData(); } private void initView() { videoView = (VideoView) findViewById(R.id.video_view); play = (Button) findViewById(R.id.play); pause = (Button) findViewById(R.id.pause); replay = (Button) findViewById(R.id.replay); // //初始化videoview控制条 // mediaController=new MediaController(this); // //设置videoview的控制条 // videoView.setMediaController(mediaController); // //设置显示控制条 // mediaController.show(0); } private void initData() { if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1); } else { initVideoPath("123.mp4"); // 初始化MediaPlayer } play.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (!videoView.isPlaying()) { videoView.start(); // 开始播放 } } }); pause.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (videoView.isPlaying()) { videoView.pause(); // 暂停播放 } } }); replay.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (videoView.isPlaying()) { videoView.resume(); // 重新播放 } } }); } private void initVideoPath(String path) { File file = new File(Environment.getExternalStorageDirectory(), path); videoView.setVideoPath(file.getPath()); // 指定视频文件的路径 } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { switch (requestCode) { case 1: if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { initVideoPath("movie.mp4"); } else { Toast.makeText(this, "拒绝权限将无法使用程序", Toast.LENGTH_SHORT).show(); finish(); } break; default: } } @Override protected void onDestroy() { super.onDestroy(); if (videoView != null) { videoView.suspend(); } } }
