我正在尝试对布局实现选框效果,以帮助它从右侧内侧向左侧内侧滚动/动画,就像自动收报机视图一样.

从以下两个链接中,您可以获得更多知识,就像股票市场通过以循环常量方式显示值来更新用户一样.

为此,我已经实现了下面的代码,使其有些类似.

public class HorizonalSlideActivity extends Activity
{
    private LinearLayout horizontalOuterLayout;
    private HorizontalScrollView horizontalScrollview;
    private int scrollMax;
    private int scrollPos = 0;
    private TimerTask scrollerSchedule;
    private Timer scrollTimer = null;
    private ScrollAdapter adapter = null;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.horizontal_layout);

        adapter = new ScrollAdapter(HorizonalSlideActivity.this);

        horizontalScrollview = (HorizontalScrollView) findViewById(R.id.horiztonal_scrollview_id);
        horizontalScrollview.setOnTouchListener(new OnTouchListener()
        {
            @Override
            public boolean onTouch(View v, MotionEvent event)
            {
                return false;
            }
        });
        horizontalOuterLayout = (LinearLayout) findViewById(R.id.horiztonal_outer_layout_id);
        horizontalTextView = (TextView) findViewById(R.id.horizontal_textview_id);
        horizontalScrollview.setHorizontalScrollBarEnabled(false); …

mMediaRecorder = new MediaRecorder();
    // Step 1: Unlock and set camera to MediaRecorder
    mCamera.unlock();
    mMediaRecorder.setCamera(mCamera);
    // Step 2: Set sources
    // activate this for recording with sound\

    mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

    mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

    mMediaRecorder.setVideoSize(getMaxSupportedVideoSize().width,getMaxSupportedVideoSize().height);

    mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
    mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

    // Step 4: Set output file
    mMediaRecorder.setOutputFile(getOutputMediaFile("movie"));

    // Step 4: Set output file
    mMediaRecorder.setOutputFile(getOutputMediaFile("movie"));


    // Step 5: Set the preview output
    mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());

    mMediaRecorder.setOrientationHint(90);

以上代码工作正常但是,视频的质量与我在本机安卓摄像头拍摄的视频不一样,我使用媒体录像机录制的视频质量较差,与原生录像机相比,我怎样才能提高视频质量.

如果有人知道帮助我.谢谢
