我正在使用videoView播放视频，但我收到致命的信号6错误，所以我得到了使用textureview而不是videoview的解决方案，但我不知道如何使用它。 这是我的代码。
public class MainActivity extends Activity {
ListView listview;
CustomListAdapter adapter;
private static ProgressDialog progressDialog;
public static int currentItem;
public static ArrayList<String> videoLIst;
public static MediaController mediaController ;
boolean pauseOnScroll = true;
boolean pauseOnFling = true;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view);
System.gc();
videoLIst = new ArrayList<String>();
mediaController = new MediaController(MainActivity.this);
videoLIst.add("http://journey.coderspreview.com/uploads/Home_Video/mov_bbb.mp4");
videoLIst.add("http://journey.coderspreview.com/uploads/experience/165/video/father-and-young-daughter.mp4");
videoLIst.add("http://journey.coderspreview.com/uploads/experience/185/video/couple-on-sail-boat.mp4");
videoLIst.add("http://journey.coderspreview.com/uploads/experience/39/video/VID-20141231-WA0006.mp4");
videoLIst.add("http://journey.coderspreview.com/uploads/experience/26/video/VID-20141216-WA0004.mp4");
listview = (ListView) findViewById(R.id.list);
listview.setAdapter(new CustomListAdapter(this, videoLIst));
listview.setRecyclerListener(new RecyclerListener() {
@Override
public void onMovedToScrapHeap(View view) {
VideoView videoView = (VideoView)view.findViewById(R.id.VideoView);
}
});
listview.setOnScrollListener(new AbsListView.OnScrollListener() {

public void onScrollStateChanged(AbsListView view, int scrollState) {
}
@Override

int visibleItemCount, int totalItemCount) {
int firstVisibleRow = listview.getFirstVisiblePosition();
if( mFirstVisibleRow != firstVisibleRow )
{
mFirstVisibleRow = firstVisibleRow;
// Cancel the video of the previous active item
VideoView prevActiveVideoView = getVideoViewForRow(mActiveItem);
if( prevActiveVideoView != null )
{
prevActiveVideoView.pause();
}
// Start the video of the new active item
mActiveItem = mFirstVisibleRow + 1;

我正面临着这两个问题。 1）在滚动视频/列表项上，对已经缓冲的项目再次开始缓冲。 2）快速滚动列表变得过于迟缓，卡住并崩溃。
请指导我如何使用视频视图中的textureview。
