我想将视频上传到服务器。我的下面的代码记录并保存了视频，但是我想让它在我按下停止按钮后立即上传录制的视频。
例如，在Instagram或Whatsapp上，相机会录制视频，停止播放时会向我们提供上传按钮。那我怎么能实现呢？
MainActivity .java
public class MainActivity extends Activity {
private static int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE ;
private TextView output;
/**
* Called when the activity is first created.
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.activity_main );
Button buttonRecording = (Button) findViewById( R.id.s );
output = (TextView) findViewById( R.id.output );
buttonRecording.setOnClickListener( new Button.OnClickListener() {
@Override
public void onClick(View arg0) {
// create new Intentwith with Standard Intent action that can be
// sent to have the camera application capture an video and return it.
Intent intent = new Intent( MediaStore.ACTION_VIDEO_CAPTURE );
// create a file to save the video
Uri fileUri = getOutputMediaFileUri( MEDIA_TYPE_VIDEO );
// set the image file name
intent.putExtra( MediaStore.EXTRA_OUTPUT, fileUri );
// set the video image quality to high
intent.putExtra( MediaStore.EXTRA_VIDEO_QUALITY, 1 );
// start the Video Capture Intent
startActivityForResult( intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE );
}
} );
}
