安卓中视频录制与播放的简单总结

1. 调用本地相机进行录像

        Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
        startActivityForResult(intent, RECORD_VEDIO);
    // 接收返回的数据
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == RECORD_VEDIO && resultCode == RESULT_OK) {
        //将返回的content://地址转换为sd卡上的绝对路径
            String filePath = convertContentUri2FilePath(data.getData());
        }
}
    // 将媒体库content://相对路径转化为普通的绝对路径（这里需要read_external_storage permission）
    public String convertContentUri2FilePath(Uri contentUri) {
        String filePath = null;
        if (contentUri != null && "content".equals(contentUri.getScheme())) {

            Cursor cursor = this.getContentResolver().query(contentUri,
                    new String[] { MediaStore.Video.Media.DATA }, null, null,
                    null);
            cursor.moveToFirst();
            filePath = cursor.getString(0);
            cursor.close();
        } else {
            filePath = contentUri.getPath();
        }
        Log.d("", "Chosen path = " + filePath);

        return filePath;
    }

2. 使用本地播放器进行播放

public void intentPlayVideo(String videoPath) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        File file = new File(videoPath);
        intent.setDataAndType(Uri.fromFile(file), "video/*");
        startActivity(intent);
        this.finish();
    }
}

3. 使用widget VideoView 进行播放

        videoView.setKeepScreenOn(true);
        videoView.setVideoPath(videoPath);

        android.widget.MediaController mediaController = new android.widget.MediaController(
                    this);
            videoView.setMediaController(mediaController);
        videoView.start();

4. 使用本地播放器播放网络视频

这里需要Intent Permission

    final String path_video =

    "http://video.ted.com/talk/podcast/2016/None/KennethLacovara_2016-480p.mp4";
    public void intentPlayVideo(String videoPath) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        Uri uri = Uri.parse(path_video);
        intent.setDataAndType(uri, "video/*");
        startActivity(intent);
        this.finish();
    }

5. 使用VideoView widget播放网络视频

// 由于资源问题，播放等待的时间较长
    final String path_video =

    "http://video.ted.com/talk/podcast/2016/None/KennethLacovara_2016-480p.mp4";

        videoView.setKeepScreenOn(true);
        Uri uri = Uri.parse(path_video);
        videoView.setVideoURI(uri);
        android.widget.MediaController mediaController = new android.widget.MediaController(
                this);
        videoView.setMediaController(mediaController);
        videoView.start();
    }

}
